Descriptions:

Raymond grinding mill is a type of industrial grinding mill used for grinding materials into fine powder, used for all kinds of materials with Mohs hardness less than 9.3 and humidity less than 6%.

What Is a Raymond Grinding Mill?

Raymond grinding mill, also known as a Raymond mill, is a type of industrial grinding mill used for grinding materials into fine powder. Raymond mill machine is new equipment instead of the ball mill in dealing with industrial powder, particularly requiring finer grinds and lower energy consumption.

Raymond mill is suitable for grinding all kinds of materials with Mohs hardness less than 9.3 and humidity less than 6%, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about 1000 kinds of materials.

What Is Raymond Grinding Mill Used For?

• Grinding Powder Plant

• Cement Processing Plant

• Mineral Grinding Line

• Metallurgy Industry

• Building Materials

What Are the Features of Raymond Grinding Mill?

1. The fineness can be adjusted between 50 and 325 mesh (315-45 microns).

2. High precision classifier and unique airtightness can ensure the quality of end products.

3. The isolated cyclone collector can effectively improve the classifying efficiency and accuracy.

4. The wear-resistant volute can effectively improve the material liquidity, decrease the air volume loss, and avoid air energy loss.

5. The bevel gear overall dive can achieve higher transmission efficiency, easy installation and adjustment, and lower cost.

6. Inner thin oil lubrication system can realize lubrication between the main bearing and drive bearing, without any additional lubrication pump, easy to maintain.

7. The curved surface shovel with the split design, only the blade is to be replaced during maintenance. Thus, the shovel has a long service life.

What Are the Parts of Raymond Grinding Mill?

A Raymond grinding mill consists of several important parts, including the motor, main shaft, grinding roller assembly, grinding ring, grinding chamber, classifier, decelerator, main frame, and other wear-resistant parts.

Several spare parts of a Raymond grinding mill are susceptible to wear due to the abrasive properties of the materials being ground. Here are some of the vulnerable parts: grinding roller, grinding ring, and decelerator. Lubrication of the contact surfaces can help reduce friction and wear.

How Does Raymond Grinding Mill Work?

After the materials enter the grinding chamber, 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 the 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 a dust filter.
