Their main function is to use effective friction force and centrifugal force to grind materials. Specifically, the barrel of the calcium carbonate mill is mainly made of rolled and welded steel plates. 

The flange on the barrel is connected with the inlet and outlet hollow shafts at both ends to form a whole with hinged hole bolts, and then the grinding body is installed in the barrel. 

The two ends of the cylinder are the feeding port and the discharging port. The devices inside the two hollow shafts provide channels for feeding and discharging, and the bushing inside can be replaced. 

The calcium carbonate mill cylinder moves around the horizontal axis, which generates a high centrifugal force in a certain process, makes it reach the specified height through the action of the mixture, and then falls in a parabolic arc. 

In this process, the material is affected by the medium and has a certain collision, and is also affected by the cylinder, crushed, rolled and ground. 

Experience, let's briefly talk about how to deal with the problem of too much sludge in the slurry in the operation of the limestone grinding plant. 

Add chemicals to eliminate the harmful effects of the sludge: commonly used water glass, soda, caustic soda, etc., can reduce the flocculation cover effect of the sludge. In order to reduce the harmful effects of a large amount of adsorbents in the sludge, it can be considered to adopt the method of adding chemicals in stages; 

Deslime the ground ore before flotation and discard it as tailings. If the content of useful components in the sludge is high, the removed sludge can also be treated by flotation alone or by water treatment. 

Commonly used desliming methods and equipment mainly include: 1. Desliming by classifier; 2. Desliming by hydrocyclone; flotation

Today, the editor continues to sort out some sudden failures and solutions of mini cement plants for you. The sudden failure of the mini cement plant is generally caused by multiple reasons such as long-term high-speed operation, job responsibility and improper operation.

The stator coil of the mini cement plant is broken down in the whole system of the mini cement plant. There will be iron-containing dust in the air around the material. After a long time of operation, the iron-containing dust will adhere to the coil of the mini cement plant stator. Thickness will cause short-circuit discharge on the surface of the stator coil. When a short circuit occurs for many times, the insulator of the coil will be damaged, resulting in the phenomenon of ignition breakdown, which will cause the mini cement plant to stop running.

Friction generates heat and heats up rapidly, causing the surface of the tile lining to be melted and scratched. If there is no spare spherical tile, it can only be stopped for inspection, and the tile surface can be repaired before continuing to use. The smoothness of the scratched surface can be restored by filing, cutting, grinding, etc., but the undamaged part needs to scrape out a micro oil groove, repair the tile mouth, and empty the material and grinding medium in the mini cement plant.

Manual methods are used. , Rotate the cylinder for no-load grinding, and when it reaches a certain level, carry out a no-load test operation with the transmission part, and then load the material and grinding medium into the mini cement plant for load operation, so that the mini cement plant can resume normal operation.
