Table Roller mill
Table Roller mill operates in the accordance with the principle of pressure comminution, making them
suitable for brittle feed products. The product is subjected to compressive stress between the grinding table
and the grinding rollers. It is used wherever a high degree of production flexibility is demanded.
Depending on the integrated classifying wheel, the table roller mill can produce end-product fineness values
between approx. 10 µm and 100 µm.
Ball mills and agitated media mills
Different designs of media mills can produce extremely high fineness powders, whether the process is dry or
The mills are filled with grinding media (balls, cylpebs, pearls), which are formed of steel or aluminium
oxides, according to the material being processed, this enables us to grind materials which have hardness
below 9 Mohs.
The motion of the grinding media inside the mill drum, is due to the rotation of an agitator or due to the
rotation of the drum itself, this rotation generates relative movements between the grinding media and the
material, which perform the grinding process in terms of impact and shear forces.
Mechanical fine impact mills
Particles are accelerated mechanically by hammers, beaters, plates, rotors or pins. Size reduction occurs
as a result of impact against a solid surface or by inter-particle collision.
One takes advantage of the fact that as compressed gas exits a nozzle, it is accelerated to extremely high
speeds. Comminution is a result of inter-particle collision in the jets of air and also in the core area which is
where the opposing jets intersect. This implies a contamination free process making these types of mills
suitable for every application.
