WET GRINDING INSTALLATIONS WITH CONTINUOUS CONICAL MILL

Continuous conic mill
The mills of this series are developed in accordance to the same principles of construction of cylindrical drum mills.
The difference lies in the shape of the milling drum: these mills have a conical shape.

This innovative milling system is protected by an international patent. Thanks to the special shape of the drum, it is possible to obtain an even and constant distribution inside the mill, according to the diameter of the grinding charge.

Owing to this simple but important principle, there is no longer need to install diaphragms. This feature combined with the continuous and simultaneous infeed of the grinding charge and raw materials eliminates the need to stop the mill to add the grinding charge.

THE MILLS ARE AVAILABLE WITH A CAPACITY RANGING FROM 40.000 TO 125.000 LT AND ARE COMPOSED OF:

- conical grinding body complete with heads, loading orifice and support with adjustable bearings;
- manifold for the slurry discharge made of stainless steel with pre-sieving system;
- wear-resistant rubber lining;
- grinding charge made of silica pebbles or aluminous ceramic balls with a high content of alumina;
- electric control board for the computerized control of the mill.

 

THE MILL DRIVE INCLUDES

a) for powers up to 630 kW

- driving unit with three-phase-induction electric motor, hydrodynamic joint, reduction unit with parallel axis , motor for the positioning of the orifices;

- transmission system by V-belts with "V"-shaped pulleys made on the drum belt;



b) for powers over 630 kW

- driving unit with electric motor fed with alternate current at low or medium tension, hydrodynamic joint by variable filling, parallel axis reduction unit with forced lubrication, gear motor with orifice positioning;

- transmission system with cylindrical-teeth pinion and crown gear assembled on the drum.


Endothermic driving units, for the cogeneration applications, are also available for conical continuous mills.
