Raymond Mill

Introduction of Raymond mill:
After many years' practice and constant improvement, the structure of R type raymond mill has been already completed day by day. It has high efficiency, low consumption, small space, little investment, no pollution and so on. Therefore it is widely used for in the fields of metallurgy, building materials, mining, chemical industry and so on. The materials must be non-flammable and non-explosive materials such as: gypsum, talcum, calcite, limestone, potassium, barite, dolomite, granite, kaoline, amargosite, medical stone, bauxite, iron oxide red, iron ore and so on. The materials should have the hardness less than 7 in Moh's scale and humidity less than 6 percent . The granularity of the end products can be adjusted from 613 to 440 micra(0.613-0.44 centimeters). It can meet different users' demands through the combinedaction of analyzer and blower.

The Structure of Raymond Mill:
The Raymond mill mainly consists of host, analyzer, blower, product cyclone separator, plumbing equipment, electric machine and so on. Among those the host is formed of frame, inlet casing, blade, grinding roller, grinding ring, inclosure and electric machine. The additional equipment has jaw crusher, bucket elevator, electromagnetic vibrating feeder, control cabinet, etc. The users can choose flexiblly according to the conditions.

The Working Principles Of Raymond Mill:
The jaw crusher breaks up the raw materials into needed feeding granularity, after that, the bucket elevator takes the material to the hopper and then the electromagnetic vibrating feeder sends them to the host' s hohlraum averaglly. In the rolling process of blade and grinding roller, the materials are feeded into the spaces of grinding rings which form the padding layer. The materials are grinded between grinding roller and grinding ring to get the purpose of making powder. After being grind, the powder is selected by classifier via the circle wind of the blower and the rough

powder wil be back to the grinding room for regrinding. The qualified powder is brought into the power collection together with the airflow. The unqualified powder will be separated with the airflow by throwing to the out wall. All the air system of the machine is closed recirculation and operate under the condition of positive-negative pressure.

Features of Raymond Mill:
1. The whole machine is vertical structure and occupies small area, strong systematicness. From the rough process to the power and to the end packing, the machine can be a independent producing system.
2. Compared with other grinding equipment, the rating of throughing screen can be 99 percent maximally.
3. The hoister’s transmission gear applies of seal gearbox and belt pulley, steady transmission, reliable operation.
4. All the important components are made of high quality casting and section. Therefore they have exquisite workmanship which guarantee the durability of the whole system.
5. Concentrate control of electrical system, advance, reasonable and highly automated.
