Nowadays, the ball mill can be divided into stainless steel, corundum, nylon, agate, polyurethane, zirconia, silicon carbide, hard alloy and polytetrafluoroethylene according to the material. It can be divided into vertical ball mill tank and horizontal ball mill tank according to the grinding form. , vacuum ball grinding tank, then how should we choose the right ball mill material?
The choice of material for the ball mill can generally depend on the administrative and mechanical properties (including physical properties and chemical properties) of the abrasive sample. The hardness of the sample must be less than the hardness of the ball mill and the grinding ball. The material of the ball mill and the grinding ball. The same is true, so we should choose the same material when choosing the ball mill and the grinding ball. If the hardness of the sample is greater than the hardness of the ball mill and the grinding ball, then the grinding is the ball grinding pot and the grinding ball , and the sample can not be crushed. The effect, and the wear of the ball mill and the grinding ball can cause contamination of the sample. It is better to use different ball mill tanks for different materials of the grinding ball instead of universal.
Ball mills of different materials commonly used in order of hardness from high to low are silicon carbide, zirconia, agate, corundum, stainless steel. Under normal circumstances, such as metal powder, ore and other hard samples can be selected to choose stainless steel ball mill tank or carbon steel ball mill tank, the hardness of the material can be selected with silicon carbide ball mill jar, glass, ceramics and other samples can be selected with nylon ball mill tank, corundum The ball mill or the zirconia ball mill can be used to grind the ball to avoid contamination of the sample with metal impurities in the metal ball mill. It also prevents discoloration of the sample. Corrosion samples with strong acidity and alkalinity are commonly used in Teflon. Ball mill, PP polypropylene, and ultra-high molecular polyethylene ball mill can be used in sample grinding applications where the purity of samples is high in food, medical, and cosmetic industries. In special cases, some samples can be vacuum ball milled or vacuum gas ball milled in order to avoid deterioration in air or need to be ground in medium gas. Vacuum ball mill tank is generally made of 304 stainless steel or 304 stainless steel lining. Several other materials, when the sample needs to be ground using a vacuum ball mill but can not be ground with stainless steel, can be lined in stainless steel vacuum ball jar such as nylon, polytetrafluoroethylene, polyurethane, polypropylene, corundum, zirconia, agate, Other materials such as cemented carbide can avoid vacuum ball milling and inert gas ball milling while avoiding sample contact with stainless steel.
According to the above principles, you can basically choose a ball mill tank suitable for your own use. Of course, because of the wide range of planetary ball mill applications and the variety of grinding samples, if you still have doubts about your grinding needs, please contact us Changshami.
