Raymond Mill

Overview
Raymond mill, also known as raymond grinder, raymond grinding mill and raymond pulverizer, is commonly used grinding equipment, mainly used for grinding barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate ore, gypsum, glass, insulation materials and other materials with Mohs hardness not more than 7 degree and humidity below 6% in mineral, chemical, construction and other industries. Final size of finished products can be adjusted within 60-325 meshes.

Principle
Firstly, raw material crushed to suitable size is elevated into the 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.
Then the ground stuff is 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.

Feature
1. Small footprint, strong systemic 
Vertical and simple structure, small footprint, systematic, from raw materials roughing to transport to the milling to packaging, forming an independent production system.
2. Good stability, high reliability
Mainframe gearing adopts sealed pulley and gear box, smooth transmission, reliable operation. Raymond Mill important parts are made of high quality castings and extrusions, sophisticated technology and rigorous process to ensure that the durability of the equipment.
3. Good product size, through screening rate is 99%
Electrical system adopts centralized control, milling workshop basic enable unmanned operation. Compared with other milling equipment, through screening rate is 99%.
