What is Ball Mill How Many Types of Ball Mills MC

03/01/2020  1. Tail Discharge Mill: The head and tail of tail discharge mill are used as the inlet and outlet of materials. When the mill is working, the material is fed from the inlet end and discharged from the other end. 2. Middle Discharge Mill: The inlet of the middle discharge mill is at both ends, and the outlet is in the middle of the mill. Generally, materials are fed from both ends and then discharged

Overflow VS Grate Discharge Ball or Mill - Why Retrofit

The overall life of the discharge end parts generally is greater than that of the feed head liners or shell liners. The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied

Converting a ball mill from overflow to grate

Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until the slurry builds up to a level at which it is possible to overflow out of the discharge

Ball Mills - Mine Engineer.Com

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back,

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at relatively higher speeds has
