Graphite Grinding Mill

Refractory materials: Graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to make graphite crucibles. They are often used as protective agents for steel ingots and as linings for metallurgical furnaces in steelmaking.

Conductive materials: In the electrical industry, graphite powder is used to make electrodes, brushes, carbon rods, carbon tubes, positive electrodes of mercury current flow devices, etc. In addition, it is also used in the manufacture of graphite gaskets, telephone parts, coatings for television picture tubes, etc.

Wear-resistant lubricating materials: Graphite is often used as a lubricant in the machinery industry. Especially under high-speed, high-temperature, and high-pressure conditions, graphite wear-resistant materials can replace lubricating oil. For example, many equipment conveying corrosive media use graphite materials to make piston cups, sealing rings and bearings, and do not need to add lubricating oil during operation.

Other uses: Graphite powder also has good chemical stability and is widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fibers, papermaking and other industrial fields. In addition, graphite powder can also be used in processes such as casting, sand foundry, molding and high-temperature metallurgy. For example, as a casting mold for glass products, it can improve the dimensional accuracy and surface finish of castings.

Bentonite grinding mill workflow

1.After big block be crushed into small particle by the jaw crusher.

2.Fall into the silo through the bucket elevator,The electric magnetic vibrating feeder under silo evenly feed the material into the Raymond mill to grinding according to the set quantity of flow.

3.When the main machine of the Raymond mill is working, the grinding roller rolls tightly on the grinding ring under the action of centrifugal force. The material is scooped up by the shovel and sent to the middle of the grinding roller and the grinding ring. The material is broken into powder under the action of the grinding force. Then, under the action of the fan, the powdered materials are blown up and passed through the analyzer. The materials that meet the fineness requirements pass through the analyzer. The materials that do not meet the requirements are returned to the grinding chamber to continue grinding.

4.The qualified material go into the double cylone powder collector with the airflow,then transport to the discharge hole by the discharge screw, the excess air suction into pulse dust collectorby the negative pressure fan and discharge after reach the standard of the dust remove .

5.The finnal products transport to the cylinder silo by Pneumatic transmission device.

Large pieces of material are broken into small particles by the crusher and sent to the storage bin by the elevator. Then the materials are evenly sent to the middle of the upper turntable through the belt conveyor weighing scale.

2.The motor of the micro-grinding machine drives the spindle and the turntable of each layer to rotate through the reducer, and the turntable drives dozens of ring rollers to roll and rotate in the raceway of the grinding ring through the pin.

3.The material is scattered to the periphery of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring by the ring roller punching, rolling, grinding and crushing. The suction effect of the high pressure centrifugal fan will draw the external air into the machine, and the coarse powder after the third layer of grinding will be brought into the separator.

4.The snail flow generated by the rotating worm gear in the separator makes the coarse particle material fall back to the re-grinding, and the fine powder enters the cyclone powder collector with the air flow and is discharged by the discharge valve at its lower part, which is the finished product.

5.The air flow with a small amount of fine dust is purified by the pulse dust collector and discharged by the fan and silencer.
