The eccentric vibrating mill CVM is a single-tube mill with a modular design. On one side of the spring-mounted grinding tube an exciter unit is placed- It consist of a bearing body and an eccenter mass, which is connected to the drive via a cardan shaft. To balance the mass of the eccenter unit, a compensating mass is installed on the opposite side of the milling tube.

Compared to conventional vibratory mills, the eccentric vibrating mill performs ellipses, circular and linear oscillations simultaneously, which result in vibration amplitudes not yet achieved. The eccentric vibrating mill is characterized by an energy input untypically high for vibrating mills. This minimizes the fraction of low-energy zones in the grinding tube. As a result, the grinding tube diameter can be increased beyond 600 mm thus increased throughput.

Applications:

Eccentric vibrating mills are used in the production of powders, pigments and fine particles in the chemical and ceramic industries, as well as in raw material processing.
Eccentric vibratory mills are suitable for wet and dry grinding of brittle materials of all degrees of hardness. The maximum feed grain size can be up to 20 mm. The feed material can be milled down to 0-5 µm as a function of its material properties and the grinding time. The main advantage of vibratory grinding is the dry fine milling and the possibility of mechanochemical activation of the materials.

• Discontinuous dry and wet micro-milling

• Mechanochemical activation of raw materials

• Dry homogenization of powders and dopants

• Chemical-physical process control (reactor function)

Advantages for the operator:

• Milling of the hardest materials

• Performance up to a factor of 2 compared to conventional vibrating mills

• Increasing the feed grain size to 20 mm and thus skipping a milling stage

• Development of new applications for which there is no suitable mill type (mechanochemistry)
