Brief Introduction of Small double roller rock crusher for sale

 

Double Roller Crusher A mining machinery, also called dual-roll crusher. Mainly used for crushing ore. This machine has a small size, large crushing ratio (5-8), low noise, simple structure, easy maintenance advantages of the material to be broken,, uniform particle size, over crushed low, easy maintenance, overload protection is sensitive, safe and reliable. For coal, metallurgy, mining, chemicals, building materials and other industries more suitable for large-scale coal or coal preparation plant (including gangue) broken. Roll crusher capacity, coupled with the limited pitch type fluid coupling between the motor and reducer to prevent power overload, overload sensors, safe and reliable. Roll spacing hydraulic adjustment, toothed roller bearing concentrated lubrication. Tooth design optimization, select the shear pull crushing, high efficiency and low consumption, the grain evenly.

 

Application of  Small double roller rock  crusher for sale

 

The roll crusher applies to the cement, chemical, electric power, mining, metallurgy, building materials, refractory materials, coal and other industries of thick, brittle block material intermediate crushing, it into the grain-size, discharging granularity is adjustable, can fight pressure strength of 160 mpa or less materials are broken. Especially in the coal industry, the use of native raw coal fragmentation, as long as after iron, removing impurity, without gangue removal, can be directly to broken, broken out of material, granularity and the crushing rate is low, thus simplifies the coal preparation process, reduce the investment and production cost

Working principle of Small double roller rock  crusher for sale

The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls. Some major advantages 

Advantage of Small double roller rock  crusher for sale

1. Double Roller Crusher has the characteristics of large breaking force, high efficiency, high crushing capacity, low operating cost and long service life. It is convenient to operate and is economical.

 

 2. The crushed materials are of equal size, thus reducing circulating load.

 

3. Large and medium-sized crushers adopt cleaning systems, which will help reduce the down time.

 

4. As the overload protection device, spring safety device allows foreign matter and iron pieces to pass through the crushing chamber without jeopardizing machines. 

 

 

Technology Parameter of Small double roller rock crusher for sale
