Understanding the Working Principle of the 3 Roller Raymond Mill in India

The 3 roller Raymond mill is a commonly used milling equipment in mining, metallurgy, building materials, chemical industry, and other industries. It is suitable for grinding non-flammable and explosive materials with Mohs hardness not greater than 9.3 and humidity below 6%. The fineness of the finished product is adjustable between 80-600 mesh.

The working principle of the 3 roller Raymond mill starts with crushing materials. Raw materials are crushed by jaw crusher to the desired size, and then the crushed materials are evenly sent to the storage hopper by the elevator. The material is transported to the main machine grinding chamber through the feeder and the inclined guide tube. The material falls into the grinding chamber and is suspended on the roller device. Under the centrifugal force of the grinding roller, it is pressed against the grinding ring and the blade is scraped. The powdered material is in contact with the air flow and eliminated by the fan, and the wind is blown into the powder concentrator and classified. The coarse powder falls into the grinding chamber and is re-grinded, and the qualified fine powder enters the cyclone powder collector with the airflow. After collection, the powder is discharged through the powder discharge pipe to become the finished product. The airflow is returned to the fan by the upper part of the cyclone powder collector to form a closed loop for circulation.

The 3 roller Raymond mill adopts a multi-layer grinding ring design, which improves the utilization rate of the grinding ring and reduces the wear of the grinding ring and roller. In the milling process, the blade system plays an important role. The material is shoveled and ground between the roller and the grinding ring, and the blade system is used to ensure the stable operation of the grinding system and the uniform fineness of the finished product.

The 3 roller Raymond mill in India has low energy consumption, high production efficiency, convenient adjustment of product fineness, and simple maintenance. The grinding roller device is detachable and can be easily removed and replaced. The grinding ring is made of wear-resistant material, which has a long service life and is not easy to be damaged. The overall structure of the mill is compact and the system works under negative pressure, which effectively prevents the processing of explosive materials from causing accidents. In addition, the mill has a small footprint and can be flexibly installed and used in various production sites.

In summary, the 3 roller Raymond mill in India is a highly efficient and energy-saving milling equipment, which plays a crucial role in the production of various mineral powder materials. Understanding its working principle and usage methods can help investors better grasp its operation and optimize the performance of the mill.
