Raymond Mill has almost several tens of years history, and the Shanghai Shibang Raymond mill has the same age with the first one all over the world.

Currently, the most popular Raymond mill in the leading position are on the basis of Newell Company and occupies 70% market share. Raymond mill’s production and development has closely related to the development of scrap industry. Firstly, most raymond mills are used for handling with some frivolous material, but with the deepening of understanding and the superiority of the crushing steel, all kinds of raymond grinding machine are developed quickly and used wider and wider. Even to the entire scrapped cars and household appliances, processed with appropriate conveyor and sorting equipment, the composition of scrap broken lines can be easily finished ,so it is no need to dismantle of scrapped cars and household appliances and it is easily to product and process automatically to get pure crushed steel, non-ferrous metals and non-metallic materials available.

Raymond mill is a common industrial powder equipment, and the main factors of affecting Raymond mill’s yield have been listed here:

1.The hardness of the material. It is obviously that the harder of the material and the harder for milling of Raymond mill and the worse for Raymond mill. Also, if the Raymond mill gets slow milling speed, its milling ability will drop down.

2.The humidity of materials. When the raymond mill’s material is too wet for milling, the material is easily adhere to inner of Raymond mill and also easily conveying the course of the next block, resulting in reduced ability of Raymond powder mill.

3.The fineness of the output material. The finer material you want, the little ability of Raymond mill persent.

4.The composition of material. Fine milling material contained before milling is bad for Raymond mill. Because these fine powder have adhesion effects that easily block conveying. So we should process before starting of raymond mill.

5.Material viscosity.

6.Raymond mill main part’s wear resistance. In our common sense, the ability of Raymond mill is up to the wear parts.

1.During the application of the raymond mill, some personnel shall be arranged to take responsibility of management. The operators must be qualified with the required technical knowledge. Before the installation of the grinding mill, the persons related to the operation should receive technical training and fully understand the operating principle, performance and regulations of the raymond mill.

2.In order to guarantee the raymond mill in a normal working state, a Safety Operation System for the Maintenance of the equipment must be established. Only in this way can this grinding mill be guaranteed to have a long-term and safe operation. Meanwhile, it is necessary to have the required repairing tools, lubricant and grease, spare parts and accessories.

3.After some period of running, the raymond mill should receive an examination and repairing. The components vulnerable to worn out, such as grinding roller, grinding ring, relieving tool etc. should be repaired or replaced. Before and after the operation, a careful examination should be carried out for the connecting screws, bolts and nuts on the grinding rollers so as to find whether they are loose or sufficiently lubricated.

4.When their application time surpassing about 500 hours, all the rolling bearings in the roller sleeves must be cleaned, and the damaged parts should be replaced. The oiling tool can be either a manual oiling pump or grease gun.
