FAM-compact-type ball mills are characterized by their compact design. All ball mill components such as the feeding and rejecting chutes, the mill body bearing and the entire drive system are fixed on one or two base frames (depending on size) and tested in a trial run before delivery.
| Test run preparation of a FAM compact-type ball mill |
The entire system is transported as completely assembled unit and merely needs to be set up on the prepared foundation.
The entire drive unit of the ball mill consisting of the main engine, mechanical start and safety coupling and gear is also assembled in the factory. Solely final adjustment and the connection of the mill body to the drive unit using a connection pipe are effected on site. This simple set-up makes the FAM compact-type ball mill immediately ready for operation.

Effective wet-grinding plants with FAM compact-type ball mills
For more than 100 years ball mills have been the most common crushing machines. Their simple design makes for high availability and reliability in continuous operation. Ball mills are used to process mineral raw materials in various industries such as building materials, ore dressing and energy management for the processing of mineral raw materials.
FAM wet-grinding systems with compact-type ball mills are used in flue-gas desulfurization (FGD) plants to reduce the maximum feeding grain size of limestone from 20mm to a product fineness of for instance P80= 32 µm. The Figure illustrates how a FAM limestone grinding plant works. The compact-type ball mill operates with a one-stage hydrocyclone in a circuit. This classifying process uses centrifugal forces to separate different sized particles.

A limestone suspension with a narrow grain size distribution and a proportion of solids of
20 –35% results from the efficient control of the suspension density.
This high reactivity suspension is temporarily stored in a tank in the FGD-plant.
