The motor of the ceramic ball mill is started by the coupling reduce voltage which lowers the starting electricity and the ball mill’s structure is divided into integral type and freestanding type advantages of the ceramic ball mill are lower investment, energy saving, structure novelty, simply operated, used safely, ability even, etc.
220.127.116.11 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 20–40 water by weight.
A Slice Mill of 72” diameter by 12” wide would replicate the result of a normal production, mill 72” in diameter as 120” long. A Slice Mill is the same diameter as the production mill but shorter in length. Click to request a ball mill quote online or call 630-350-3012 to speak with an expert at Paul O. Abbe to help you determine.
