4r Series Raymond Mill For Limestone Calcite Barite Dolomite  

Introduction:
Raymond roller mill  is used in the mining, metallurgical, industrial, chemical engineering and building material industries.
This series, our patent product, is used in grinding the non-inflammable and non-explosive stuff with Moh’s hardness below 9.3 and humidity less than 6%, such as barite, limestone, ceramics, slay, etc.
Fineness of final product can be adjusted between 80 and 425 meshes and part of then can add up to 1000 meshes of final being equipped particular parts, the machine can produce coarse powders ranging from 30 to 80 meshes.

Structure:
1. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
2. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach.
3. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.

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.
