Introduction of Raymond Roller Mill
Raymond roller mill is commonly used milling equipment. It is suitable for all kinds of mineral powder preparation and pulverized coal preparation, such as raw ore, gypsum mine, coal and other non-flammable and non-explosive materials in the fine powder processing with hardness less than 7 and humidity less than 6%. The product size is adjustable on required in the range of 100-425 meshes.
Working Principal of Raymond Roller Mill:
The materials enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls.
After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding chamber for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust filter.
Structure of Raymond Roller Mill:
1、The whole system of Raymond mill consists of main frame, separator, blower, piping device, electromagnetic vibrating feeder, electric control panel, etc.
2、Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach.
3、Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4、Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant.
5、The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
6、Low dust pollution, smoothly running.
7、The use of electromagnetic vibrating feeder to feed evenly, easy to adjust, small size, light weight, fuel-efficient power-saving, easy to maintain.
