Raymond mill is an efficient grinding milling machine instead of ball mill for processing ore powder. The Raymond Mill has strong advantages such as strong system, high screening rate, smooth transmission, high abrasion resistance and convenient maintenance. Raymond mill is widely used in grinding and processing of mineral products in mines, building materials, metallurgy, chemical industry and other fields.

Raymond mill is widely used in the pulverization of barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass and other non flammable and explosive materials less than 7 and less than 6%.

Raymond mill is mainly composed of main engine, fineness analyzer, blower, finished product cyclone powder collector, bag dust collector and connecting duct. According to user's demand, it can be equipped with crusher, hoist, storage bin, electromagnetic vibration feeder and electrical control cabinet and other auxiliary equipment.

After the material is crushed to the desired particle size, the material is sent to the hopper by the hoist, and then the material is sent to the mill room of the rayon grinding mill evenly and continuously through the vibrating feeder. The grinding roll is swinging outward, the grinding ring is pressed tightly, and the scraper is shoveled between the grinding roller and the grinding ring because of the rotation of the centrifugal force. The purpose of comminution. The fine powder after the grinding of the material is sorted with the air blower's circulating wind, and the coarse materials fall back to the regrinding. The qualified fine powder enters the finished whirlwind collector with the air flow, and is discharged through the powder pipe, that is the finished product.

Sand machine is a very important mechanical equipment in the production and processing of sand and gravel. The sand making machine can make the ore making into fine aggregate. The sand machine is a large ore processing machine. There are a lot of parts in the sand machine. The lining plate is a part of the sand machine very close to the key.

The lining plate is installed inside the sand making machine. The lining plate of the sand making machine plays a protective role on the equipment itself during the crushing operation. Due to the high hardness of materials crushed by gravel sand-making machine, the lining plate will suffer varying degrees of wear and tear during the long-term crushing process. The majority of users need timely replacement when the liner of the sand making machine is worn out. How to replace the lining board of the sand making machine?

The longer the lining plate of the sand making machine, the higher the power consumption. When processing hard materials, users need to select short lining boards and soft materials to select long lining boards. Select the short lining of the fine material, and select the long lining for the coarse material. Generally speaking, the material less than the closing edge of the discharge port can not exceed 10%, if more than 10%, then the power consumption increases, product granularity becomes flake. The increase of moisture content of viscous materials will affect the throughput of materials. Generally speaking, the moisture content of materials is not more than 5%.

In the process of sand making operation of sand making machine, great vibration problems will occur. After a long period of operation, the balance of sand making machine equipment will be reduced. The re operation of the sand making machine will lead to the phenomenon that the roller can not rotate normally, and the high quality liner is added at the bottom, which not only reduces the wear degree, but also prolongs the service life of the gravel making machine.
