The future development trend of toothed roller coal crusher

Since its extensive localization, the toothed roller coal crusher is currently mainly used in major industries such as electric power, mining, and chemical industry. With the continuous progress of science and technology, its development is becoming more and more professional and intelligent. For example, in the mining and coal industries, there are more jaw and roller coal crushers, and in the electric power and chemical industries, especially the industries that use circulating fluidized bed boilers for coal-fired power generation, they are more inclined to use four-tooth roller coal crushers.

Therefore, professional and targeted development is the future development direction of the toothed roller coal crusher. In addition, with the continuous progress of remote control technology, the combination of PLC remote control and local control is widely used in the toothed roller coal crusher, and the intelligent level has been significantly improved. For example, the toothed roller coal crusher produced by Xinxiang Gaofu Screening Machinery has the core technology of the toothed roller coal crusher - liquid spring integrated parallel flashback technology, and anti-sticking and uniform distribution technology, and is equipped with PLC electric control cabinet to realize the combination of remote control and local control in the centralized control room.

Therefore, the GF series toothed roller coal crusher produced by it is a representative of specialized and intelligent products in the industry.

Toothed roller coal crusher equipment occupies an important role in the mining equipment industry, and the toothed roller coal crusher not only has the international leading technical level in the processing of raw materials such as coal deep processing, electric power, mining machinery, building materials industry, etc., but also makes an indispensable contribution to the national economic infrastructure. As we all know, the toothed roller coal crusher is the most important crushing capacity of mining equipment, which occupies a great significance in the crushing capacity of the toothed roller crusher, and it is a super crushing resource in the sand and gravel production line. Zhengzhou Dingsheng has a professional toothed roller coal crusher, which can be used for crushing both dry and wet materials.

The two relative running rollers of the toothed roller crushing pin crusher are running at differential speed, and the teeth are cleaned with each other, which can avoid the sticking and blocking of the clay, and the toothed roller is a forced occlusion of the principle of a crushing, and the liquid degree of the particles after crushing is evenly distributed, which is convenient for the sintering and other processes. In on-site operation, the crushing particle size can be quickly adjusted by the lead screw** to quickly meet the requirements of different particle rot levels.

The integration of the above technical characteristics determines its low price and high quality, and the price is close to half the price of imported equipment.

Compared with similar products at home and abroad, the differences between this new type of toothed roller crusher are mainly manifested in the following aspects:

1) It has the dual functions of screening and crushing.

The two toothed roller shafts are fixedly installed, their relative movement is like a rotating griddle screen, and the material that meets the particle size requirements is first leaked by the tooth roller or the gap between the tooth roller and the lining plate to achieve preliminary screening, so as to avoid the re-crushing of that part of the material through the roller tooth, which not only reduces the over-crushing rate and energy consumption of the material, but also reduces the crushing time of the roller tooth and prolongs the service life. At the same time, the toothed rollers run in opposite directions at differential speed, which has better shearing and tensile crushing effects. The movement of the roller teeth also makes the material forced to be discharged after crushing, which is not easy to cause congestion, so it is also suitable for viscous materials and materials with high moisture content.

2) The two-tooth roller is non-circular, non-meshing, and non-constant speed operation.

This feature greatly increases the shear crushing effect of the ore and reduces the blockage phenomenon of toothed roller crusher at home and abroad.

3) Double overload protection is adopted.

On the one hand, the torque limiting type hydraulic coupling absorbs the impact force generated when crushing to make the machine run smoothly, on the other hand, it plays a safety protection role for the whole machine, once the equipment is stuck or overloaded, the hydraulic coupling will automatically cut off the transmission of power, so that the motor and the large and small tooth rollers play a protective role;

The machine is equipped with a moving jaw buffer device, when the toothed roller is overloaded due to crushing force, it will force the compression spring to move out radially horizontally to increase the gap between the toothed roller and the jaw plate, and protect the toothed roller and the jaw at the same time.

4) Flexible assembly and easy maintenance.

The toothed roller shaft is equipped with a broken toothed ring, which is inlaid with a tooth sleeve and fixed with bolts. When the wear of the rack reaches a certain level during the crushing process, it can be replaced individually and quickly, thus reducing downtime and reducing production costs.

5) Reasonable structure and long life.

The crushing roller teeth are arranged in a special spiral, which is not only convenient for the discharge of materials that meet the particle size requirements, but also reduces the number of roller teeth that are stressed by the toothed rollers at the same time, which is conducive to crushing large materials. At the same time, the dual role of the tooth roller, the lining plate and the jaw body is used to realize the crushing of the material, reduce the workload of the gear teeth, improve the crushing efficiency, and prolong the service time of the whole machine.

The toothed roller coal crusher is suitable for crushing raw coal in coal mines, coal preparation plants and other industries (allowing raw coal to contain less than 30% gangue), and can also be used to crush other brittle materials similar to the hardness of raw coal. It has the characteristics of high efficiency, long life, full sealing, low noise, small crushing and uniform discharge particle size.

The crusher installation method is divided into left and right, people stand on the side of the mobile tooth roller to look at the machine, the motor is arranged on the left side of the left, and the opposite is the right type.

The toothed roller crusher is suitable for coal, metallurgy, mining, chemical industry, building materials and other industries, and is more suitable for the crushing of raw coal (including gangue) in large coal mines or coal preparation plants. The toothed roller crusher has a large crushing capacity, and the motor and the reducer are connected with a limiting fluid coupling to prevent power overload, and the sensor is overload protected, which is safe and reliable. The toothed roller spacing is hydraulically adjusted, and the toothed roller bearing is centrally lubricated.

Tooth shape optimization design, tensile and shear force selective crushing, high efficiency and low consumption, uniform granulation.

The birth of PCM toothed roller crusher completely replaced the existing 2PGC toothed roller crusher in China.
