Year of construction: 2025, condition: new, ceramic ball mill ,Batch ball mill ,also called ceramic ball mill ,it is used for fine grinding of feldspar,quartz,clay,ore and so on.The ceramic ball mill is mainly used for material mixing, grinding,uniform product fineness,and saving power.It can be dry or wet.The machine can use different liner types according to production needs to meet different needs.The fineness of the grinding operation is controlled by the grinding time ceramic ball mill Working principle when ball mill working,steel balls inside drum will rotate with the drum to some height,and then steel balls fall down with materials to reach the point of grinding. Working Principle of Ceramic ball mill ceramic ball mill ,Intermittent ball mill grinding operation is finished in the cylinder body. When the cylinder rotates, materials ascend to a certain height and then fall along a certain path due to the balls' gravity. Two forces are generated on the balls inside. One is the force on balls through tangent direction; the other is a opposite force in the contrast to the diameter of balls, as a result of the force generated when the balls slide down. These two forces will constitute a couple for the steel balls. The balls are squeezed between the cylinder and the adjacent steel balls, so the couple can make unequal-sized friction force. The balls will orbit along with the cylinder axis and then fall down, which can produce a strong impact force on the ores in the cylinder body and, as a result, the ores will be crushed. In conclusion, the ores in the cylinder body are mainly crushed by composite effect of peeling force, impact force and extrusion force. Ceramic ball mill also named Intermittent ball mill which adopts the wet intermittent operation, is used for fine grinding and mixing the material such as feldspar, quartz, clay ceramic raw materials. The discharging and the mud size can through through 1000 sieve pore. This machine is high milling machinery, materials should be Broken in the fineness of the state into the grinding mill to get the highest efficiency and economic benefits. The cement mill is key equipment for the grinding process of the cement clinker after the crushing process of it. It is mainly used in the cement silicate product industry.

The cylinder adopts new type step lining to increase the grinding area. And it is easily repairable and changeable. The new designed separate-chambered structure adopts flexible lifting blade and fixed lifting blade and it is easily fixed and repaired. Working Principle of Cement Mill The cylinder will rotate by the transmission device. Due to the inertial centrifugal force, the steel balls will stick on the liner plate and rotate with the cylinder together. When the steel balls come to a certain height, it will fall down by gravity and impact the raw material. And the repeated going-up, falling down, slide and roll of the steel balls can grind the raw material together with the liner plates. Bdjdpfjvzx Ausx Ab Tek
