In general ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um. This duty represents reduction ratios as great as 100. The ball mill an intermediate and fine-grinding device is a tumbling drum with a 40% to 50% filling of balls.
The grinding medium of cement dry ball mill includes steel ball steel rod steel pipe stone porcelain ball etc. the steel ball is divided into cast iron bearing steel carbon steel and other materials and the diameter of steel ball varies from 15mm to 125mm.
Introduction : Dry rod mill is a dry grinder machine with fine discharge. Capacity : 64-180t/h Improvement : dry rod mill is developed with the international technical level which is featured with simple structure strong production capacity especially suitable for the fine materials.
Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility cryogenic wet and dry grinding at room temperature makes the CryoMill the ideal grinder for quantities up to 20 ml.
Ball mills are used for crushing and mixing of materials. While rotating the grinding media balls beads pulps etc. and the material rotate along with the mill drum. The feed material is grinded as a result of the grinding media shifts and mill drum`s rotation. There are several construction types for the ball mills.
