WhatsApp: +86 18037808511For an extremely basic answer, an end mill is rotated in the spindle of a milling machine and moved against a piece of material (metal or otherwise) and the rotating 'blades' on the edge of the tool will slice away material to produce the desired form or shape. Originally an end mill was used to remove material using only the cutting flutes ...
WhatsApp: +86 18037808511The water amount in ball mill cylinder is an important index in ball milling process. It reflects the carrying energy of particle materials in ball mill. Therefore, the water amount through ball mill cylinder is corresponding with the material throughput of ball mill, which should be controlled in a suitable limit.
