The most important measure to reduce dust leaking is to reform the new technology, new devices, and new materials, so it can achieve mechanization and automation [10].
The material of cartridge is replaced by metal mesh.
Through using the materials and devices above, the actual concentration of high-allergenic dust touched is lower than 0.1mg/m3 which meets the occupational exposure limit.

NPC: With the repeated action of the load, the state of pressed materials is changed from stationary to motion.
Since the friction of between pressed materials particles is converted from static friction to dynamic friction, the frictional resistance between the material particles is reduced.
