Function of Raymond Mill in Powder Industry

Raymond mill is a kind of grinding equipment widely used in mine development. In practical application, Raymond Mill plays a very important role. Raymond mill is mainly composed of main engine, analyzer, fan, finished product cyclone separator, micro powder cyclone separator and air duct. The main machine of Raymond mill is composed of frame, air inlet volute, blade, grinding roller, grinding ring and casing.

The space occupied by the roller in the working chamber of the main machine of Raymond mill is small, and the working space is larger. The high-pressure wind energy of the blower enters into more working area, so that the ground fine powder has more opportunities to be quickly taken out of the main machine and into the cyclone collector, so as to avoid the invalid grinding of the ultra-fine powder, This is the main reason why the output of the new energy-saving Raymond mill is higher than that of the ordinary three roller Raymond mill.

Structure Features of Raymond Mill:

1、 The fineness of the finished powder is relatively uniform, and the screening rate is as high as 99%, which is difficult for other grinding equipment.

2、 The important parts are made of good steel, and the wear-resistant parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation.

3、 Centralized control of the electrical system, grinding workshop can basically achieve unmanned operation, and maintenance is simple and easy.

4、 Its shape belongs to three-dimensional structure, covers a relatively small area, and complete sets of strong, from fast material to finished powder independent of a production system.

5、 The transmission device of the machine adopts sealed gear box and belt wheel, with stable transmission and reliable operation.

Although Raymond mill has good performance in use, as a manufacturer in production also need to pay attention to its maintenance, reasonable maintenance will bring better benefits, otherwise it will affect the overall economic development, or even lag behind.

1、 In order to ensure the normal use and production of the mill, the user usually needs to formulate a series of systems, such as "equipment maintenance safety operation system", and prepare the necessary maintenance tools, grease and corresponding accessories.

2、 After using for a period of time, the equipment needs to be overhauled, and the vulnerable parts such as grinding roller, grinding ring and blade need to be overhauled and replaced. Before and after using the grinding roller device, the connecting bolts and nuts should be carefully checked to see whether there is looseness and whether the lubricating grease is sufficient.

3、 As for the grinding roller device, when it is used for more than 500 hours, the grinding roller should be replaced again, and the rolling bearings in the double roller sleeve must be cleaned. The damaged parts should be replaced in time, and the oil filling tools can be manual oil pump and grease gun.

4、 Also need to pay attention to the user is that Raymond Mill in the process of use should be a fixed person responsible for care, the operator must have a certain level of technology. Before the installation of Raymond mill, necessary technical training must be carried out for the operators to make them understand the principle and performance of the mill and be familiar with the operating procedures.
