The summery of Raymond mill

Raymond Mill is relevant towards the grinding and processing of more than 280 types of non-flammable and non-explosive materials with hardness lower than 7and humidity lower than 6% in mining, construction, chemical industry and metallurgy.

Raymond mill also named Raymond grinder or Raymond grinding mill can grind many kinds of non-explosive and non-flammable mineral materials such as marble, sandstone, granite, gravel, basalt, gypsum, calcite, quartz, limestone etc. The functions sometimes like the stone grinder machine. Raymond mill is a kind milling equipment of industrial miller and used widely in grinding industry.

milling equipment

When the Raymond Mill is working, firstly, raw material is crushed by rock grinder to the required size, and 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.

Raymond Mill Features:

1. Three-dimensional structure

2. Land-saving

3. The screen-passing rate can reach to 99%

4. The transmission is steady and reliable;

5. The transmission device of mainframe adopts airtight gear case and zonal wheel.

6. Centralized control for the electric system, convenient to operate.

7. Applications 80-325mesh fine powder grinding

8. Field of application Agriculture, biology, construction materials, glass / ceramics, mining, mineralogy / metallurgy

9. Feed material medium-hard, hard, brittle, tough

10. Size reduction principle pressure

11. Material of grinding tools manganese steel, Chromium - molybdenum Alloy

12. Dust Filter System With Bag Dust Filter

13. Durability depending on feed material

Working Principle of Raymond Mill

First material should be crushed into the desired size by powder mill, and delivered to the Silo by Bucket Elevator. Our Designed Vibrating Feeder will feed the material into the grinding room. With the air current from the Air Blower, those powder conforms to the fineness degree will be blew into the cyclone collector and those powder that is not consistent with the desired size will return to the grinding room to be re-ground. The whole system is airtight circulation, and the circulatory flow under the negative pressure.

Make the safe operation of Raymond mills

When starting milling, you should check whether all the Raymond mills maintenance doors closed tight, check the crusher jaw plate gap is in line with the feed grain size, adjust the analytical engine speed should reach approximate finished size requirements. And press to start the order.

The Steps of starting the Raymond pulverizer:

1. starting basket bucket elevator;

2. activate the jaw crusher;

3. when there are material silo, start analysis machines;

4. to start the air blower (air load to start until the normal operation after the load);

5. Start the host, start the host instant starts electromagnetic vibrating feeder. Grinding work shall be started at this time. Simple sequence of operations is as follows: Start: enhancing machine crusher →Fan →analyzer mainframe → Feeder.
