Raymond Mill, also known as Raymond Mill, Raymond Mill, is a widely used suspended roller disc fixed disc mill. The following is a detailed introduction about it:

Working Principle1

Grinding process: The grinding roller of Raymond Mill rolls tightly on the grinding ring under the action of centrifugal force, and the scraper scoops up the material and sends it to the middle of the grinding roller and the grinding ring. The material is crushed into powder under the action of the grinding pressure.
Grading process: The powder after grinding is taken away by the airflow of the fan, and is graded by the analyzer. The powder that meets the fineness enters the large cyclone collector with the airflow through the pipeline, is separated and collected, and then discharged through the powder pipe as the finished powder; the powder that does not meet the requirements returns to the grinding chamber for further grinding. The entire airflow system is a closed cycle, and it circulates under negative pressure.
Structural composition

Host: It is the core component of Raymond Mill, consisting of a frame, an air inlet volute, a scraper, a grinding roller, a grinding ring, a cover and a motor, responsible for the grinding and preliminary crushing of materials1.

Analyzer: Also called powder selector, used to classify the ground material. According to different fineness requirements, the powder that meets the requirements is selected, and the unqualified powder is returned to the host for re-grinding1.

Blower: Provides air flow power for the entire system, allowing the material to circulate in the pipeline to achieve grinding, classification and transportation processes1.
Feeding equipment: Such as electromagnetic vibrating feeder, which can evenly and quantitatively feed the material into the host grinding chamber for grinding1.

Dust removal equipment: such as bag filters, dust collectors, etc., used to collect dust in the system, protect the environment, and achieve dust emission standards13.
Performance characteristics1

Strong applicability: It can be used to process more than 280 materials in various mineral, chemical, construction and other industries with Mohs hardness not greater than 9.3 and humidity below 6%, such as barite, calcite, potassium feldspar, talc, etc.
The finished product has uniform particle size: the screening rate can reach 99%, which can meet the requirements of different users for product fineness.
Compact structure: three-dimensional structure, small footprint, strong set-up, from block material to finished powder, it is an independent production system, which can effectively save production space.
Stable operation: The main engine transmission device adopts a closed gear box and pulley, and the transmission is stable; important components are made of high-quality steel, and wear-resistant parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation.
Easy operation: The electrical system adopts centralized control, and the grinding workshop can basically achieve unmanned operation, and it is easy to maintain, reducing labor costs and labor intensity.
Application field

Mining industry: used for ore grinding, such as fine powder preparation of quartz, feldspar, kaolin, bentonite and other ores, to provide qualified raw materials for subsequent mineral processing, smelting and other processes14.
Building materials industry: can process limestone, marble, gypsum and other materials, produce cement, lime, gypsum powder, etc. for construction, and can also be used to prepare wall insulation materials, coating fillers, etc.1.
Chemical industry: suitable for processing various chemical raw materials, such as activated clay, activated carbon, phosphate rock, etc., to provide the required powdered raw materials for the production of chemical products1. Metallurgical industry: used for grinding metal ores such as iron ore and bauxite, and providing raw materials with suitable particle size for sintering, ironmaking, steelmaking and other processes in the metallurgical process14.
