Survey:
WFJ ultra micro pulverizer is a kind of advanced pulverizing machine, which is developed by absorbing the technology of Japan Hosokawa company and combining with the actual situation in China. The unit has the advantages of stable technical performance, low noise, low power consumption and high production efficiency. Compared with domestic models, the fineness of its products can be adjusted arbitrarily, and the grinding temperature rise is slow. Therefore, it is especially suitable for the grinding of sugar, plastic powder, Chinese medicine and other heat sensitive materials. The unit is composed of pulverizer, fine powder collection device, powder transmission pipeline and electric control cabinet. The main machine is equipped with a wind grading device, which makes the particle size of the products arbitrarily adjustable and prevents excessive crushing. The crushed powder is conveyed to the cyclone and bag filter by negative pressure for collection and discharged through the discharge valve.
Main structure and working principle of main engine:
1. Main structure and working principle of pulverizer:
The main machine is composed of frame, stepless speed reducer, automatic feeder and crushing chamber. The grinding chamber is equipped with classification device, lining ring, grinding knife and other main working parts. The classification shaft is sleeved into the grinding main shaft, and the bearing seal is labyrinth type.
2. Working principle:
The material is pushed into the crushing chamber by the automatic feeder. Due to the negative pressure, the material entering the crushing chamber is impacted and sheared by the pulverizer at high speed, and is also crushed by the high-frequency vibration caused by the eddy current. The pulverized powder enters the grading wheel due to the negative pressure. Due to the rotation of the grading wheel, the powder a is also affected by the centrifugal force F of the pneumatic knife e, and the powder is larger than the grading The particle size, which is thrown to the cone sleeve, returns to the crushing chamber, continues to crush, and the qualified materials are sent to the aggregate pipe by the aerodynamic force to the auxiliary machine for elimination.
