3. Mill head 4. Trunnion liner 5. Bearing liner The best a ball mill can get FL has installed almost 4000 ball mills at locations worldwide – which has given us a unique insight into the stresses and strains arising out of ball mill operations. The large alternating stresses placed on ball mill trunnions and heads are a great example.
