Features of raymond grinding mill:, 1.Fine finnished products, 2.Energy saving, 3.Wide application - details see: https://www.machineto.com/2013-hot-selling-raymond-grinding-mill-10284713

Introduction of raymond mill:

Raymond mill is suitable for grinding the nonflammable and non-explosive materials with humidity below 6% and Mohs hardness less than 7, such as barite, calcite, limestone, marble, glass and so on. It is widely used in mining, chemical industry and building material.

Features of Raymond Mill

1. Reliable working condition
2. High efficiency
3. Stable processing capacity
4. Stable working performance
5. With qualified products and good service, our company supplies series Raymond Roller Mill(Raymond Mill), which is suitable for grinding barite, calcite, potash feldspar, talcum, marble, limestone, ceramics, etc.

Structure of Raymond Mill:

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.
4. Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant.
5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

Working Principle of raymond mill

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 sets airflow system is closely sealed up and circulated under condition of negative and positive pressure.
