Working Principle & Advantages
1.The material (≤6mm) is sent to the grinding chamber under negative pressure. The grinding chamber consists of three grinding zones:
The first grinding zone: pendulum - can grind various harder materials, such as minerals, leather, animals;
The second grinding zone: pendulum knives - can grind various fiber materials, rhizomes, whole grasses, fruits, fungi, flowers and others;
The third grinding zone: fixed knives - control particle size by adjusting the gap.
The material is conveyed to the classifying chamber. Centrifugal force field is generated by classifying impeller.
The qualified fine powder is moved to the center of the rotor, sucked away by draft fan, and then collected by cyclone collector; the coarser particles return to grinding chamber for secondarily grinding. Material recovery rate is above 99%.
2. Designed according to the "GMP" standard of the pharmaceutical industry. Stainless steel. Dust-free and can be installed in clean workshop.
3. Easy to operate, high efficiency and low cost. Widely used in pharmaceuticals and food industries.
4. Could be used not only in single machine, but also in closed loop system with air classifier to obtain finer particles.

About Our Equipment
Impact mill
High efficiency, has two milling effects of impact and grind, large milling ratio, simple structure, stable operation, suitable for milling medium-soft hard materials.
Jet mill
Uses the high speed turbulence airflow generated by compressed air or superheated steam as milling power. Impact extrusion, friction and shear between the particles or between the particles and the fixed plate occur, so as to achieve milling.
Ball mill + Classifying
The ball mill and classification production line refers to a complete set of milling system composed of Ball mill, cyclone, dust collector and fan.
