Grinding Mill, Raymond Mill

1.Lower power consumption& Low pollution 2.Reliable working condition 3.Easy installation, easy operation 4.ISO9001:2008&CE

Features of The 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 hoster'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.

Concentrate control of electrical system, advance, reasonable and highly automated.

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 makig powder. After being grind, the powder is selected by classifier via the cucle 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.

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 Use of Raymond Mill

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.
