Unique Advantages

To achieve ultrafine, high purification, functional, intelligent, carbon reduction, energy conservation and environmental protection is the mission and responsibility that time has given us.

Wide grinding range

Adapting to the grinding of different drugs.

Fine Grinding

Particle size is fine, could reach 300 mesh.

PLC programming control

Achieve hierarchical authority management, storable, vibration sensors etc. using effective warning to prevent problems before they occur.

No sieve classification, negative pressure operation

Independent air inlet and exhaust system, meet GMP requirements.

Working Principle

Creating the future of advanced materials with powder technology.

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.
