For Operating Cement Mills

Electrostatic precipitators (ESP) - FL

In the cement mill ESP, inlet dust load can exceed 700 g/Nm 3. Our ESP includes a pre-separator hopper to separate coarser dust and maximise overall efficiency. FL’s coal mill ESP can be designed with a N 2 or CO 2 purging system. Explosion flaps can be added to the roof to meet ATEX/NFPA standards requirement for vent pressure clearance.

The operating principle of the ball mill

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

Ball Mill Maintenance & Installation Procedure

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.
