Ball Mill Maintenance Installation Procedure

Oct 19, 2016 · Where a concrete floor slab is adjacent to the mill foundations, an expansion joint should be used. For convenience in maintenance, the mill foundations should be equipped with jacking piers. These will allow the lifting of one end of the mill by use of jacks in the event maintenance must be carried out under these conditions.

Earth Retaining Systems for Deep Excavations

Concrete prefabried panels may be designed quite thin by the use of good quality concreting and reinforcement. These may allow cheaper alternative projects than conventional diaphragm walls. Sheet piles or prefabried steel slabs can also be used as alternatives for reinforced concrete panels.

Grinding Mills

Size for size, the Intermediate Level mill offers a capacity greater than the Overflow mill and less than the LowLevel diaphragm mill. Use of the diaphragm is almost universal with ball mills in the cement and rock products industries because of the many dry grinding operations in this field.
