Working Principle

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.
