Description

Introduction
The series is used in grinding the non-flammable and non-explosive stuff which has the Moh’s hardness below 7,humidity less than 6%,such as gypsum,talc,calcite, limestone,marble,feldspar,barite,dolomite,granite,kaolin,bentonite,bauxite,iron ore etc.,the final products change from **3 micron to *4 micron.Through the function of separator and blower, it can meet different customers’demand.It is ever the mainstream grinding machine in powder making industry.

Features
1.Take little working spaces.
2.Closed system and steady performance.
3.Durable and long service life.
4.It can be controlled intensively and high automation.

Working Principle
Firstly,raw material is crushed by jaw crusher to the size required,then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder,evenly and continuously into the grinding chamber for powder-processing.The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials,send to the middle between ring and roller to accomplish the grind.

After this, the ground stuff are carried by the air from the blower into the separator for screening.The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding.
