ZENITH stone grinding machine
This type stone grinding machine is mainly used for grinding the material with middle and low hardness, below 6% moisture, and the material should be non-explosion and non-flammability, such as: calcite, chalk,limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite,iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite,barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassiumore pumice, etc
stone grinding machine Features:
1. Reliable
2. High capacity and low cost
3. Easy adjustment of product fineness
4. Clean, environmental protection
stone grinding machine 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. The set's airflow system is closely sealed up and circulated under condition of negative and positive pressure.
