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.

Belt transmission, stable and reliable

The traditional method uses a DC motor with poor precision control, high motor failure rate and limited speed.We use belt transmission, stable and reliable, achieve high speed.

High Precision Classifying Rotor

High-precision classifying rotors ensure precise apex cutting for demanding product requirements.World-class ceramic rotor with line speeds up to 65m/s. High-precision and high-purity ultra-fine powder classifying can achieve a specific gravity of 26g/cm, D100: 8um.

Automation technology, stable and consistent

Automation technology, precise weighing control, free from human interference, stable from start to finish; super fine powder grinding is more stable and reliable; ceramic protection technology, no metal pollution, meet the requirements of high purity materials; zero metal contact of the whole powder process , to meet the highest standards.

Large scale, Large production capacity

We have the jet mill which own the largest production capacity currently operating in China and have independent intellectual property rights. Supporting 1000KW power air compressor, the capacity is 57T/h (toothpaste grade calcium hydrogen phosphate D97=<10um).

Working Principle

Creating the future of advanced materials with powder technology.

The classifier and cyclone separator, dust collector and induced draft fan form a classifying system.Under the action of fan suction, the material is moved from the lower inlet of the classifier to the classifying zone with the ascending airflow. Under the strong centrifugal force generated by the high-speed rotating turbine, the materials are separated and the fine particles which meet size requirements through the classifier impeller gap into the cyclone separator or the dust collector, the coarse particles entrained part of the fine particles collided with the wall and the velocity disappeared, descending along the cylinder wall to the secondary air outlet, and the coarse and fine particles were separated by the strong washing action of the secondary air. The fine particles rise to the classification zone for secondary classifying, and the coarse particles are lowered to the discharge port for discharging.

Product Atlas

From dots to planes, from detail to the whole, from product to management, and from consultation to compliant production, we have always insisted on the relentless pursuit of perfection and the courage to surpass ourselves.
