Method one: gas sweep A common cleaning method is relatively simple, requiring the use of air pump, purge gun and fume hood. It is often used for cleaning dry and non-sticky samples after grinding, such as soil, coal, dry cement and so on. After the grinding of such samples, the grinding tank and the grinding medium can be put into a fume hood and cleaned with a blowing gun, and can be used again after completion. Method two: Wipe with paper towels or dry cloth Paper towels or dry cloth are also common cleaning methods. It should be noted that paper towels and dry cloth should be clean and pollution-free. This method is also suitable for cleaning dry and non-sticky samples after grinding. After grinding, the grinding tank can be directly wiped with paper towels or dry cloth, grinding ball is only suitable for slightly larger diameter, less. Method three: water washing Water is our daily cleaning common liquid, also suitable for grinding tank and grinding ball cleaning. Before cleaning, we can soak the grinding tank and grinding ball, and then rinse the tank and ball with running water. For oil, solvent and other substances that are difficult to clean with water in the tank, the grinding ball and detergent (such as washing powder, small pieces of soap, detergent, etc.) can be put into the grinding tank with water, put the lid on the ball mill to run over for a few minutes, and then wash with pure water, and then dry or dry. Method four: add cleaning solvent Some sample residues, only water and detergent is difficult to clean, then we can choose the appropriate cleaning solvent according to the chemical properties of residual samples, such as acetone, butanone, ethanol (alcohol), oxalic acid, hydrochloric acid, and so on, and then soak cleaning.

The length to diameter ratio below 2 is the short mill, also known as the ball mill, generally for single bin, for rough grinding, multiple ball mills in series can be used as a first-level mill. Medium length mill with length-diameter ratio of 2~3. Length-diameter ratio above 4 is long mill, also known as tube mill, its interior is generally divided into 2~4 bins.

Definition of wear: Wear is the inevitable result of friction caused by continuous loss, transfer or residual deformation of surface materials in relative motion of objects in contact with each other. Some wear is beneficial, such as "grinding," which reduces the surface roughness of parts and sharpened the blade.

If the lining plate is of a special shape, such as corrugated or stepped type, it must be reasonably corrected and the average value should be used.
