Working Principles

After being fed into grinding chamber by a frequency transducer, the material is ground under the action of roll extrusion and shears and grind, and then enters into the classifying-section with the upward air and the coarse and fine fraction are separated by centrifugal force of classifying wheel and attraction force of draft fan. The unqualified powder is rejected to the grinding chamber and the qualified enters the cyclone and the bag collector for collection and purified gas is exhausted.

Performance and Characteristics

The new generation of roll crusher has breakthrough technology in performance compared to the other ones.
1. The innovative design enables low consumption and grinding efficiency in operation owning to the pressure equalization, save 20-30% energy under the same production capacity compared to other ones.
2. Classification precision is improved because of the innovative self-detaching grading plant and flow field structure as follows:
◇It can meet the standards of particle size distribution which you need by adjust.
◇Assure the product free of oversized particle and residue owning to the exact cutting point.
◇Fineness of product can be D97≤5 micron
3. The particle size ranging from 50 to 5 micron is available because of innovative design of flow field structure; it is not only used for fine powder, but also for coarse grain which usually is produced by Raymond mill.
4. The service life of critical components made of wear resistant material is long and the rotor is wearproof for grinding medium hard materials, abrasion and contamination are minimized for high hardness materials.
5. Feeding system equipped with magnetic separator assures material free from iron pollution and abrasion to the equipment.
6. The main machine installed with resilient cushion member is free of shock, riding stability, and little maintenance and long service life.
7. The system does not need the foundation, the investment and installation time are reduced largely.
8. The main body is oiled by a quick lubricating system.
9. The material with less than 8% moisture can be ground directly because of its own wind power.
10. Environmental protection measures:
◇The noise from main body is separated by isolation booth design and the draft fan is equipped with a silencer
◇Operation under Negative Pressure and free of dust..
11. Automatic control, easy and stable operation.

Application Fields

Non-metal mines, Chemical industries, building materials, minerals, refractory materials, metallurgy, new material, environment protection, feedingstuff, pesticide, food and dry powdery material.
Meanwhile, it can be used for fibroid materials such as cellulosine and herbal medicine.
