What is the working principle of The large-scale-scale Industrial Raymond Mill

The large-scale Industrial Raymond Mill is being widely used in the industrial field today. Ever related to the non-metallic mineral grinding, industries will choose to use the Raymond Mill. So, do you know about the working principle of the mill? What material can the Raymond Mill be used on?

The large-scale industrial Raymond Mill is a mechanical mill with mature technology. It uses the friction force generated by the rotation of the grinding roller and the grinding ring to achieve the effect of crushing and grinding the material. Its working principle is mainly divided into two parts: grinding and collection. 

Grinding part:

Raw materials with suitable particle size are sent to the main engine through the feeding mechanism. The high-speed rotating grinding roller is tightly rolled on the grinding ring under the action of centrifugal force, and the material is scooped up by the spatula and sent to the grinding area formed by the grinding roller and the grinding ring , the material is crushed into powder under the action of the rolling pressure; under the action of the fan, the ground material is blown up and passed through the sorting machine, and those that meet the fineness requirements pass through the sorting machine, and those that fail to meet the requirements are sorted Stop the selection machine and return to the grinding chamber to continue grinding. 

Collection part:

1. Closed-circuit system: The qualified materials sorted out are blown into the cyclone collector through the pipeline, and the separation of material and gas is realized through the action of the cyclone. The collected materials are sent to the next process through the discharge valve, and the separated air flows through the action of the fan and then enter the main engine, participating in the next cycle. The excess air in the system passes through the pulse dust collector and is discharged into the atmosphere to ensure the stable operation of the system. The collection efficiency of the pulse dust collector reaches 99.99%, ensuring that the discharge meets environmental protection standards.

2. Open circuit system: the sorted finished material is blown into the pulse collector through the pipeline, and the separation of material and gas is realized through the function of the filter bag. The collected material is sent to the next process through the discharge valve, and the separated finished product is passed through the blower, entered the pipeline, then discharged into the atmosphere. The collection efficiency of the dust collector reaches 99.99%, ensuring that the discharge meets environmental protection standards.

Large-scale industrial Raymond mills can grind a lot of materials, mainly non-metallic minerals, such as limestone, dolomite, calcite, kaolin, talc, gypsum, bentonite, wollastonite, etc., which are often used in refractory materials. It can be seen that, such as grinding bauxite, magnesia, mullite, etc.. Coal powder, activated carbon, humic acid, etc. can also be used for grinding. Generally speaking, as long as the grinding materials’ Mohs hardness is below 7 and the humidity is within 6%, the large-scale Industrial Raymond Mill can be ground into fine powder. 

Guilin Hongcheng is an early domestic manufacturer that independently developed large-scale industrial Raymond mills. It is a leader in the field of ore grinding equipment in China. It has more than 100 technical patents and a research and development team of more than 100 people. It is committed to providing customers with a full set of green milling solution. Large-scale industrial Raymond mill is one of Guilin Hongcheng's flagship products. Compared with traditional Raymond mills, it has more stable performance, higher production capacity, and better environmental protection.
