cement vertical roller mill

For the cement industry were 30,25,20,10,8.8 tons of annual production and other industries use to meet the users of different materials with different yield and grinding requirements. At the same time I also have fine vertical grinding mill, the State Development Center has fine vertical cement mill as the "Eighth Five-Year" period focused on promoting the application of high efficiency, new energy-saving products.

The working principle of vertical roller mill

1, the main structure and function

Roller is the main material for rolling mill parts. Mill built with two pairs of roller, each pair of rollers mounted on the same shaft, rotating at different speeds.

Disc fixed to the reducer output shaft, the upper part of the disc material bed, the bed material a circular groove.

PRM-type separator mainly composed of vertical roller mill ,roller, disc, compression device, reducer, motor, housing and other components.

Fineness of separation is an important component of the decision, which consists of adjustable speed drives, rotor, guide blades, housing, meals, fighting off the cone material, composed of the outlet, and the separator works similar.

Pressure device is called the grinding pressure of the components provided by the high pressure oil station, hydraulic cylinder, rod, storage and other components, able to exert enough pressure roller grinding of materials.

2, the working principle of vertical roller mill

The material flow through the separator, in the role of guide vanes and the rotor, the coarse material to the disc from the hopper cone, the fine powder with a mill with air, dust collection device in the system to collect, is the product, the material in the contact process with the gas being dried to the required product water, by adjusting the angle and the wind guide vane separator rotor speed can be different fineness of the product.

Motor through reducer drive the disc rotation, the current hot air from the air inlet into the mill, the material from the feed opening falls on the central disc; the centrifugal force, material to the disc edge and moved across the ring groove on the disc by the grinding roll rolling and grinding, to the edge of the disc, moving through the air with the wind at the starting of large particles falling back to disc on the direct re-grinding.

Compared with the ball mill, vertical roller mill with the following features;

Compared with the cement vertical mill to mill the advantage is obvious, in order to establish a more intuitive description of the characteristics of MPS vertical mill, following the annual output of 10 tons of cement and production of raw material preparation system, for example, compared with the two HRM vertical mill and ball mill kinds of program indicators.

Grinding efficiency; drying large capacity; into the grinding material Liaodu large, medium and large vertical mill can save two broken; products, chemical stability; stars are homogeneous gradation, product Liaoduo uniformity is conducive to burning ; process is simple; low noise, less dust, the operating environment clean; metal loss, high utilization; use of the economy.

Assuming an annual output of 10 million tons of cement in order to meet production needs, may use the following two options:

Programme 1: HRM1300 vertical mill grinding system

Programme 2: @ 2.2 × 6.5 米 closed-circuit grinding system

Table II installed capacity of the two programs, technical and economic indicators in Table III.

As can be seen from the above comparison, the choice of vertical roller mill to reduce annual operating costs only 380,200 yuan, and the level of technology and products to improve yield, save energy, improve the operating environment, reducing noise and pollution, and enhance ability to adapt to other aspects of the play is not assess the long-term benefits.

Vertical roller mill grinding cement technology

International Progress:

• In the past 10 years, the vertical roller mill for cement and slag grinding technology has made an important breakthrough.

• the world's largest cement producer Ruishi Hao Rui Group in 1998 and Loesche companies, Hon Chong Cement Plant in Vietnam into the first vertical mill for cement grinding. Since then, more and more vertical roller mill for cement and slag in the final grinding.

•vertical roller mill for cement producers traditional grinding system compared with the practical and the quality of the cement to produce the same concerns have been eliminated. Vertical mill grinding cement has many advantages, not only has the economic advantage, while versatile, represents the future direction of development of cement industry.

Since the first vertical mill grinding cement in use since the cement grinding process, especially a large cement grinding power consumption and reduce power consumption is also a great potential. Cement and slag grinding, the vertical mill grinding energy is about 50% of the traditional ball.

• vertical mill is an air swept mill, so the fan's energy consumption must be included in the grinding system. Generally speaking, the vertical roller mill grinding plant ball mill power consumption is about 70%, which is new on the market to other comparable grinding technology.

Vertical roller mill raw material recycling technology

5000t / d production line of raw material preparation using RMR57/28/555 vertical roller mill. In the trial production period, there are often caused by improper operation of bucket elevator loop current is too high, resulting in crushing bucket elevator, mill jump stop the phenomenon, not only to field a larger increase in the workload of staff, also affected production. Through the operator and the constant review and practice, the current form of a set of effective control measures to effectively prevent the occurrence of such phenomena.

Problems outside the circle bucket elevator model: NSE300 × 33350, transmission capacity of 450t / h, motor power 75kW, rated current of 140A, the alarm value of 150A. In actual production, often due to sudden changes in raw materials, incoming instability and other reasons, the status changed to wear, resulting in material outside the circle, resulting in high current hoist. Early in the production, operation of commonly used method is a rapid reduction of the volume of feed at the same time increase the grinding pressure, appropriate to reduce the speed of the powder, so that as many as possible with the gas from the powder mill, mill to reduce the volume within the material, thereby reducing the external of recyclable materials. However, in practice found that such methods of operation to adjust for too long, large number of materials from outside the mill, will eventually cycle crushing bucket elevator. As the hoist is a chain of relations with the vertical roller mill, skip hoist will stop after the mill shut down.

Improvements through exploration and discovery, when the cycle of bucket elevator reach the threshold current 140A, even to the alarm value of 150A, to take the following measures, which can effectively avoid the cycle of bucket elevator of death.

① trip into the grinding belt, prohibited materials into the vertical roller mill. ② to quickly lower the ground pressure, so that in the disc of material formed on a temporary thick layers, so that the cycle bucket elevator plummeted materials. ③ appropriate separator to reduce speed, so that in fine grinding as soon as possible from outside the mill (separator speed should not be too low to prevent the raw material through the rough.) ④ When the cycle of current bucket elevator downward trend and dropped to 140A, can reduce the feeding amount to 200 ~ 300t / h, open the feed into the grinding belt, adjust the grind to a steady state condition, then normal operation.

Practice has proved that such methods of operation is simple, rapid decrease in a relatively short period of time outside the volume of recyclable materials to effectively prevent the large amount of recyclable materials caused by circulating outside the bucket elevator crushing, grinding stop jumping phenomenon long-term operation of the mill has played a crucial role, thus ensuring the normal kiln feed, but also greatly reduces the power consumption of raw material grinding system

If changing the upper and lower parts of the heavy hammer of the phase angle can change the direction of travel of raw materials.

Flannery Plant's new J-1175 jaw crusher adds to C&D waste processing

Jaw Crusher jaw plate on the use of two materials extrusion and bending and breaking all kinds of coarse broken or hardness of the material in the crushing machine. The broken body from the fixed jaw plate and movable jaw plates, jaw plates close to the time when the two materials Jibei broken jaw plate away when the two nesting population is less than block from the bottom of the discharged material. It's crushing action is carried out intermittently. This stone crusher due to simple structure, reliable and can be broken advantages of hard materials are widely used in mineral processing, construction materials, silicate and ceramics industries.

80 to 20 of the 20th century, 800 tons of material per hour, breaking a large jaw crusher to a particle size has reached approximately 1,800 mm. Commonly used jaw crusher with elbow board and two single brackets. The former moving jaw at work only a simple swing arc, so called simple swing jaw crusher; the latter for the swing arc to move up and down also, so called complex swing jaw crusher. Jaw Crusher widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and other sectors, breaking strength no more than 320 MPa of various materials.

Single-plate jaw crusher elbow mobile jaw plate up and down movement to promote the role of nesting, and its level of travel is greater than the upper part of the lower part of bulk materials easily broken, so the broken above the elbow plate efficiency. The disadvantage is that jaw plate wear faster, and the materials have been smashing the spontaneous increase in energy consumption. In order to protect the important parts of the machine is not damaged due to overload, and often the shape of the small size of the brackets designed for weak links, overload the machine when it first deformation or fracture.

In addition, to meet the requirements of different marker size and compensation jaw plate wear and tear, but also the addition of nesting population adjustment device, usually in brackets after the frame between the seat and adjust the pads or radiotherapy, wedge. However, in order to avoid damage to replace broken parts to affect production, but also can be used hydraulic equipment to achieve security and adjustment. Some jaw crusher also has a direct hydraulic drive to drive fixed jaw plate, to complete the materials in the crushing action. These two types of hydraulic transmission equipment jaw crusher, often referred to as hydraulic jaw crusher.

Gyrating crusher cone crusher is used in the shell cavity of the cycle within the cone movement of materials generated extrusion, splitting and bending and hardness of coarse broken all kinds of large-scale ore or rock crushing machinery. Broken cone axis with the upper bearing bush in the middle of the beam, the lower end of the eccentric sleeve is placed in the hole. Sleeve rotates around the broken cone axis for eccentric cycle exercise machine of its crushing action is continuous, and therefore the efficiency of higher than jaw crusher machine. To the early 70s, large gyratory crusher has been able to handle material per hour, 5,000 tons, the largest feeding up to 2,000 mm diameter.

Cone Crusher - broken machine industry outstanding in the field

Mining machinery industry from the last century, since the early '90s, in China is big and amazing the last 20 years the rate of growth Rang Shi Jie of China was the envy of, in particular on infrastructure in the field, in recent years, China was born Henduo landmark buildings, such as the "Water Cube", "Oriental Pearl", "Three Gorges Dam", "Qinghai-Tibet Railway," and so on.

The construction of key projects each have a large demand for mining machinery, mining machinery companies in recent years so that our exponential growth, the mining equipment company's strength is also uneven, most companies produce jaw crusher, Impact crusher, Raymond mill, high pressure medium speed mill, cone crusher rely on imitation, imitated by many companies can only say that the normal machinery of production, simply can not talk about security, stability, and energy saving.

Impact crusher test is successful, for the safety of equipment, in order to achieve the international advanced equipment, energy standards, in order to impact crusher to achieve maximum output, China Mining Equipment Co., Ltd. for as long as a year of technical improvements of work, we have repeated on the cone crusher machine was empty running test, impact crusher on-site production tests, test some out by the data, our products vsi impact crusher has the international advanced standards . Impact crusher pcl sand making machine is an alternative product, the appearance of side pcl sand making machine and the impact crusher of the difference is not very obvious, but in energy efficiency in vulnerable parts of the loss is totally standard with Europe and the United States, pcl sand making machine using a "stone blacksmith" works, vsi impact crusher works by "a stone at stone." Our impact crusher to enter the market over the past year, through the re-discovery, impact crusher in pebbles, river pebbles, granite, basalt, limestone and sand has a good model, by the client as "sand experts" the world. Mining machinery proved to lack of innovation there, the blind imitation and no way out. Domestic enterprises this year, very little innovation in the field of mining machinery, most of all ism, impact crusher came, not only in China, is the impact of the global cone crusher is broken is a masterpiece of mining machinery in the field!

Single rotor impact crusher

(1) without even sieve-plate impact breaker (impact crusher )

(2) take even sieve-plate impact crusher. This crusher machine  can control the product, so big particle size, narrow particle size distribution range of products, product size evener. This expression due to sieve grading and broken plays a big role of particles.

(3) single reversible impact crusher (back rotor broken). The rotor can reverse, positive rotation feeding port in the body, decorate in the upper part, crushing cavity symmetrical arrangement of two back plate, double rotor counterattack crusher is the following 3 kinds.

Therefore, we should not only help us choose a real machine, but also not forget the love that we carefully choose Haohao De machine!

Details crusher machine

Crusher is mainly used in industry to smash the operation, compared to grinding equipment, crushing machine for large size, large particles of material more significant the effect. Therefore, in powder processing, ore mining and smelting operations in the sand crusher is widely used as its preferred tool for initial processing. Depending on the model, divided into crusher cone crusher machine, impact crusher, jaw crusher, etc., different works were used in the processing of different materials. So, in addition to the role of crusher broken, the broken machine if there are other more extensive use?

In order to explore new uses for the crusher, the definition of the crusher is the basic principle of what the industry can be close with. The traditional view that Crusher machine is mainly used for grinding and slag made a first step, when the processing of crude materials. To adapt to the expected range of grinding equipment. Then, in the general sense had to restrict the use of crusher ore smelting or materials made on.

However, by year of practice, we find that many industries require materials or broken. Not solely limited to the traditional light industry. The emerging industry in the crushing area, far can learn from experience. For this reason, many companies spend a high cost, detour to find other ways for processing. The results are not satisfactory.

So, we look at the building demolition industry. Often these involve public works, this is indeed in recent years, new areas of application Crusher machine. Through large-scale removal of machinery, can be split into building blocks of granular materials, and then transported to processing plants. Many removal companies often do not realize the role and use of these materials and rash of these valuable substances as a waste. But at this stage, the Shanghai Dragon King has been successfully carried out some construction sand recycling program design. This demolition of old buildings by the construction waste generated after the application of crusher sand and gravel products can be effectively turned into recycling. On the one hand to reduce the burden on enterprises, it also addresses the requirements of urban waste disposal and environmental protection.

Again, this stage is rather deep in some ore hidden underwater, while others need excavated underwater tunnel operation. Shanghai Dragon King through the use of high corrosion-resistant material crusher, can effectively complete the crushing operation in the water. The advantage is to facilitate the recovery of the broken product. Traditional fooled underwater tunnel excavation or mining, if there are massive stone must be designed very large conveyor so that transport to the surface. Underwater operations through this stone crusher, the particle size range of control in a certain range, you can try to siphon pumping, significantly reduced the conveyer installation complexity.

On the other hand the application is, there are many minerals will form during processing of granulated slag block, so do not facilitate their post-treatment. So, how could it be more efficient disposal of slag? Now, many manufacturers have been broken in the testing machine using slag removal operation. Great order of nickel on the election equipment in this crusher's recycling of slag, it is known, the effect is very obvious, and saves its mineral waste processing costs.

Crusher role in the extensive use of outside

Crusher is mainly used in industry to smash the operation, compared to grinding equipment, crushing machine for large size, large particles of material more significant the effect. Therefore, in powder processing, ore mining and smelting operations in the sand crusher is widely used as its preferred tool for initial processing. Depending on the model, divided into crusher cone crusher machine, impact crusher, jaw crusher, etc., different works were used in the processing of different materials. So, in addition to the role of crusher broken, the broken machine if there are other more extensive use?
In order to explore new uses for the crusher, the definition of the crusher is the basic principle of what the industry can be close with. The traditional view that Crusher machine  is mainly used for grinding and slag made a first step, when the processing of crude materials. To adapt to the expected range of grinding equipment. Then, in the general sense had to restrict the use of crusher ore smelting or materials made on.
However, by year of practice, we find that many industries require materials or broken. Not solely limited to the traditional light industry. The emerging industry in the crushing area, far can learn from experience. For this reason, many companies spend a high cost, detour to find other ways for processing. The results are not satisfactory.
So, we look at the building demolition industry. Often these involve public works, this is indeed in recent years, new areas of application crusher machine. Through large-scale removal of machinery, can be split into building blocks of granular materials, and then transported to processing plants. Many removal companies often do not realize the role and use of these materials and rash of these valuable substances as a waste. But at this stage, the Shanghai Dragon King has been successfully carried out some construction sand recycling program design. This demolition of old buildings by the construction waste generated after the application of crusher sand and gravel products can be effectively turned into recycling. On the one hand to reduce the burden on enterprises, it also addresses the requirements of urban waste disposal and environmental protection.
Again, this stage is rather deep in some ore hidden underwater, while others need excavated underwater tunnel operation. Shanghai Dragon King through the use of high corrosion-resistant material crusher, can effectively complete the crushing operation in the water. The advantage is to facilitate the recovery of the broken product. Traditional fooled underwater tunnel excavation or mining, if there are massive stone must be designed very large conveyor so that transport to the surface. Underwater operations through this crusher mahcine, the particle size range of control in a certain range, you can try to siphon pumping, significantly reduced the conveyer installation complexity.
On the other hand the application is, there are many minerals will form during processing of granulated slag block, so do not facilitate their post-treatment. So, how could it be more efficient disposal of slag? Now, many manufacturers have been broken in the testing machine using slag removal operation. Great order of nickel on the election equipment in this crusher's recycling of slag, it is known, the effect is very obvious, and saves its mineral waste processing costs.
