Raymond grinding mill machine

Product introduction

Raymond grinding mills are one of the indispensable equipment for non-metallic ore grinding processing in the powder industry. The pulverizer produced by Shuguang machinery adopts the advanced structure of similar products at home and abroad, and is updated and improved on the basis of the traditional Raymond grinding mill.This equipment has higher efficiency than ball mills, lower power consumption, smaller floor space and lower one-time investment.

Purpose and scope of use

Raymond grinding mills are widely used in barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass , Mohs hardness of insulation materials is not more than 9.3,high-fine powder processing of more than 280 materials in non-flammable and explosive mineral, chemical, construction and other industries with a humidity below 6%,the granularity of the finished product of R-type Raymond grinding mill can be adjusted arbitrarily within the range of 80-325 mesh, and when some materials are high, it can reach 2000 mesh.

Structure

The structure of Raymond grinding mill machine is reasonable and scientific, and it is mainly composed of main machine, analyzer, blower, finished cyclone separator, pipeline device, motor, etc. The main machine is composed of frame, inlet volute, blade, grinding roller, grinding ring, Shell composition. Raymond grinding mill machine with jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc., can be combined into a complete grinding production line.

Working principle

1. Raymond milling process: When working, add the material to be crushed into the machine from the hopper on the side of the machine casing.Relying on the grinding roller device suspended on the plum blossom frame of the main engine, it revolves around the vertical axis,

at the same time it rotates itself;due to the centrifugal force during rotation, the grinding roller swings outwards and tightly presses on the grinding ring, so that the shovel blade scoops up the material to be sent between the grinding roller and the grinding ring. The grinding roller achieves the purpose of crushing the material due to the rolling and rolling of the grinding roller.

2. The air separation process of the Raymond mill: After the material is ground, the fan blows the wind into the main casing to blow up the powder, and the analyzer is placed above the grinding chamber for sorting, and the coarse material falls again. It enters the grinding chamber for regrind, and the fineness meets the specifications and enters the cyclone collector with the wind flow. After being collected, it is discharged through the powder outlet, which is the finished product. The wind flows back into the fan from the return duct at the upper end of the cyclone collector. The wind path is cyclic and flows under negative pressure.The increased air volume of the circulating air path is discharged through the exhaust gas pipe between the fan and the main engine, and enters the small cyclone collector for purification treatment.

Product advantages

1. Easy to transport and install

With the unique structural design, it occupies a smaller space area and is more convenient for transportation, installation, operation and maintenance;

2. High efficiency and less pollution

The Raymond grinding mill adopts PLC electrical automation control, which effectively reduces the failure rate and labor cost of the equipment, while achieving high-yield, high-efficiency production, and a good production environment with low noise and less pollution;

3. Fineness can be adjusted arbitrarily

The fineness of grinding powder can be adjusted arbitrarily between 80-800 mesh, and the applicability is more flexible and wide. 

4. Long parts replacement cycle

The replacement cycle of grinding roller and grinding ring is long, thus eliminating the shortcomings of short replacement cycle of wearing parts of centrifugal crusher.
