5. The size of the ball mill is large, and it is necessary to carry out lifting work during the process of replacing the ball mill liner. The hoisting ball mill liner is the responsibility of the hoist. The lifting process requires attention to the operation of the wire rope and the hook. 6.
Filling Degree. Ball charge filing degree: Measurement by free height: 1- Measure average internal g,diameter, Di. 2-Measure height, h, in three different points along axis for each grinding compartment. For Best results the measurements takes place in an empty mill (mill feed stopped for approx. 10 min).
Wet ball milling has several advantages over dry ball milling. Let's explore some of them: 1. Better Grinding Efficiency. The liquid in wet ball milling acts as a lubricant, reducing friction and improving the grinding efficiency. The particles are more effectively ground and dispersed, resulting in a finer particle size distribution.
Grinding Action: The ball mill operates 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. Monitoring and Adjustments: Continuously monitoring the process ...

A ball mill is simply a container that is filled with pebbles (either of porcelain or stones e.g. Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, low-speed ...
Feeding >15mm to a ball mill this size is not typical - much larger ball mills (>21' or 7.0m diameter) typically get 12-16mm feed (from what I have seen in my experience) With regards to 3.5"- 4" media, typically for Ball mills of this size (16'), max size of ball used should be around the 50-60mm.
