SD turbine Food fine mill
Specifications
SD turbine Food fine mill has the features of high output, fine fineness, low noise, low energy consumption, simple maintenance
1. General Description
SDtype impact mill is designed by Zhejiang LEAP Pulverization equipment Co., Ltd. It is widly used for comminution of low-hardness materials in fields of chemical industry, dyestuff, paint, plastics, coating, pesticide, foodstuff, feedstuff, metallurgy and non-metallic minerals.
2. Structure and Working Principle
SD impact mill consists of machine housing, a door, turbo, main shaft and screen. During running, the motor drives the main shaft and turbo for high-speed rotation. The turbo and blades on screen ring integrate a compact comminution area. Material fed in this machine in the roating airflow rub compactly and impact strongly to the inner side of turbo vane, and the material is re-grinded in the gap between vanes and blades.
During this process, the turbo sucks in large amount of air for cooling the machine and material and transferring fines.
The product fineness depends on specification of material and dimension of screen, and as well as flow volume of material and air.
Special labyrinth sealing at the bearing part efficiently blocks powder getting in, so as to extend the bearing¡¯s application life.
Two O-type rubber sealing ring in the door guarantees no powder pollution.
