Attritors
Our attritors are used for grinding and homogenizing a wide variety of material suspensions. The machines are primarily used in the hard metal, ceramic and powder industries.
A vertically arranged agitator rotates in a container equipped with grinding media (grinding balls). The high kinetic energy of the agitator and the huge amount of contact points of the grinding bodies ensure rapid grinding, homogenization and mixing of the raw materials.
The grinding bodies are selected according to the process (diameter, shape, material). The processing of very hard and abrasive raw materials is also possible.
Further technical features:
- Explosion-proof version (ATEX) possible
- Simple manual machine operation up to modern Siemens system controls and process visualizations.
- Double-walled grinding container for heating or cooling the suspension
- Pumping around the suspension (circulation) during the grinding process
- Container inner jacket made of stainless steel or with application-specific lining/coating
- Wear protection for the agitator
- Soundproofing insulation (optional)
- Additional equipment for powder handling and filling the machine
- Integration into higher-level production systems on request

Ball mills
The ball mill or drum mill is a machine for the classic crushing, grinding and homogenization of raw materials.
The ball mill consists of a horizontal cylindrical drum that is supported on both sides. The grinding chamber is filled with grinding bodies, usually grinding balls, and the material to be ground (raw materials and process liquid).
The rotation of the drum and the targeted movement of the grinding media generates kinetic energy, which acts on the material to be ground in the form of impact, friction and shear forces.
The material can be cooled or heated during the process via the double wall of the container. The ball mills are suitable for batch processes. Filling/emptying takes place via a nozzle on the circumference of the drum.
Our ball mills are also available in an explosion-proof version (AETX).
Further product features:
- Drive power and speed according to customer process
- Filling/draining opening adapted to customer process
- Variable speed (optional)
- Wear protection or application-specific coating for the drum (optional)
- Control / degree of automation according to customer requirements
