Last year both of our ball mill shells cracked where they sit on shoe bearings. This happened to almost all of shells, which have been used by our contactors in Iran with the same sub supplier (like seven shells!) after a while new shells with same supplier were replaced (no difference but just a biggest welding fillet where the shell mounts).

Initially the mill was jacked-up to remove the weight of the mill and the charge from the trunnion. The sections in the upper half of the trunnion that either exhibited cracking or were less than 1.905cm (.75″) thick were removed.
The crack generally is directed down into the base metal, right at the weld toe. If you don't create a smooth transition of weld metal to base metal, you can disrupt the flow of forces through the weld. Such a high volume of weld metal creates significant shrinkage forces. When these forces exceed the strength of the weld, cracking ensues.

Cement mill – Cracks in the mill ends . This case of damage was investigated to decide if repair-welding is a sufficient solution when the ends of a cement mill start to crack and are in danger of breaking. To ensure that the damage is repaired reliably, the cause of the damage must be investigated and weld seams examined carefully.

Composite rubber shell plates Most mills can be converted from metal liners to composite rubber liners. These liners combine the best characteristics of metal alloys and rubber to obtain a superior design for use in AG/SAG, grate discharge, overflow ball mills and grinding ball mills. By using special alloy steel segments
the same as the shell axis slope at each pier. Please note that the shell axis slope at a particular tire is not necessarily the same as the kiln overall slope. This is because vertical shell deflection due to gravity may not be the same uphill and downhill of a tire. 6. The tire and support roller radiuses do not vary by more than .010".

8.3.2.2 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.

Ball milling replaces potentially unsafe hand grinding of chemicals and compositions. The crushing of the material is accomplished by the repeated falling of heavy balls onto it, over and over, inside the mill jar. So, it sounds like I need a ball mill. I want my chemicals to have small particle size and be intimately mixed. What are my choices?
