Stone Raymond mill

Barite Raymond Mill Introduction:

Barite Raymond mill is used for grinding the barite, limestone, kaolin, cement, slag, etc, below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and nonexclusive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 30-425 (600 the largest) meshes. It is possible to produce 30-80 mesh coarse powder through special device in the machine. 
 

 

Barite Raymond Mill Features :

1. Compared with other mills under the same power output increased 20-30%, Barite Raymond Mill grinding roller pressure on the material under the action of the spring in the high-pressure increase 800 - 1200kg.

2. Barite Raymond Mill on the Mohs hardness of less than 9.3 processing of mineral materials can be crushed.

3. Barite Raymond Mill wide range of product particle size, particle size up to 0.613 mm the thickest (30 mesh) particle size of generally up to 0.033 mm (425 mesh), few materials can reach 0.013 mm the smallest (1, 000 head).

4. Barite Raymond Mill dust effect is entirely up to the national dust discharge standard.

5. Barite Raymond Mill analyzer easy to adjust.

6. Barite Raymond Mill grinding device of overlapping multi-stage seal, seal.

Structure of  Barite Raymond Mill 
Barite Raymond Mill is mainly composed of main unit, analyzer, fan, dischargeing cyclone separator, powder cyclone separator and air duct. Among them, the main unit consists of frame, blow shell, shovel, grinding roller and grinding ring.

 

Barite Raymond Mill Working principle:

First the materials are crushed by the jaw crusher,then the crushed materials are transferred to a hopper by the bucket elevator ,fed uniformly.quantltatively and continously by the vibration feeder to the grinding chamber of the main frame for grinding.the grinded particles are brought up by the air current from the blower into the classifier for classification.the particles with the required fineness are brought up by the air current through the pipe into a collector for separation and collection,the finished particles are discharged from a pipe outlet,Because of some moisture contained in the materials to be grinded,the heat resulting from grinding leads to the vaporized air which changes the airflow volume,Moreover,the outside air inhaled from the narrow gaps of the piping connections can increase the volume of air current.Therefor,it is necessary to adjust redundant air pipe between the blower and the main unit for keeping the balance of the air current.Then the redundant air is quided into a cloth bag of a dust cleaner to collect the fine power in the air,Finally, the redundant air is discharged after purfication.

Barite Raymond Mill Main Parts

The main parts of Barite Raymond mill is grinding roller, grinding ring, grinding roller assembly, the plum flower frame, air flue, coupling, perching knife and so on.
