1. Product Overview

The Raymond mill or the Raymond grinder is a kind of grinding plant used widely to grind materials in the industries of metallurgy, construction materials, chemical engineering and mining. Raymond mill can process the non-flammable and non-explosive materials with the mohs hardness of smaller than seventh grade and the humidity less than 6% such as the gypsum, talc, calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, iron oxide, iron ore etc. The fineness of the finished products is between the 0.613mm-0.44mm range. By working with the analytical machine and the fan, the Raymond mill can meet different requirements from customers.

2. Advantages

1.High efficiency,small occupied area,low power consumption;

2.No environmental pollution and clean workshop for the producing process with little dust;

3.The concrete base weight required is only 3 times of that of other similar machines thus the construction expenses is greatly reduced;

4.Small vibration while using and doesn't need shock-absorbing device;

5.Large load adjustment scope, so it can run under various environments;

6.Can bear very strong explosion pressure;

7.Long cycle of the replacement of grinding roller and the ring;

8.The grinding roller adopts new material and new craft, which ensures long service life and low maintenance cost;

9.There is gap between the grinding parts; it can start with load or offload.

3. Working Principle

The jaw crusher breaks the bulk materials to the required particle size, the bucket elevator will convey the materials to the storage bin and then the magnetic vibrating feeder will transport the materials to the main body of the Raymond mill or raymond grinding mill uniformly. When the scraper knife and the grinding roller of raymond grinder rotate at the same time, they raise the materials to the space between the grinder roller and ring, forming a plastic layer. Materials grind each other between in the space between the grinding roll and grinding ring of grinding plant. The ground powder is conveyed to the analytical machine by the draught fan and the fine powder with the required fineness will flow to the cyclone collector along with the air flow. Then they are discharged as the finished particles. The unqualified powder is thrown out of the external wall of the raymond grinding mill and rough powder falls into the grinding chamber under the gravity force. The whole airflow system is a closed circulation under the positive and negative pressure.
