Grinding

Reduce product size to a specific fineness

From pre-crushers for the comminution of coarse materials to jet and ball mills for ultra-fine grinding: Hosokawa Alpine offers mills for a wide range of fineness levels. The mill type that is best suited to your application depends not only on the desired fineness level, but also on which raw material is to be ground and for what purpose.

Pre-Crusher
The primary crusher is used to pre-crush coarse-grained materials. It is often used as the first crushing step in compaction with roller presses.
More about
Granulators and Shredders
Granulators and Shredders are available in numerous sizes and designs. Popular applications include recycling tasks and the pre-shredding of products before they are fed into the actual grinding process.
More about
Hammer Mills
Hammer mills are suitable for grinding soft to medium-hard products. Grinding is carried out by rotating hammers that strike the material to be ground. In addition, the hammers throw the material against the mill wall, where it is further broken up by the impact.
More about
Flake Crushers
In a flake crusher, the product is ground between the rotor and the screen so that a defined upper grain size limit is achieved. Screen mills are suitable for grinding soft to medium-hard brittle materials.
More about
Table Roller Mills
Table roller mills operate on the principle of pressure comminution. The material is subjected to pressure between the grinding plate and the grinding rollers and is thus comminuted. They are suitable for brittle-elastic materials, with the fineness of the end product ranging between 20 100 µm.

Fine Impact Mills
In a fine impact mill, the material to be ground collides with the grinding tool and is broken down into small particles. Our fine impact mills cover a wide range of requirements, ensuring that you get the right mill for every application.
More about
Classifier Mills
A classifier mill combines a fine impact mill and an air classifier in a single machine. This means that the mill covers two different process steps. They are suitable for a wide range of applications in the food, chemical, pharmaceutical/cosmetics, and minerals industries.

Spiral Jet Mills and Fluidised Bed Opposed Jet Mills
Unlike other types of mills, jet mills do not have grinding tools. Instead, the material to be ground is repeatedly thrown against each other in a gas stream and thus ground and crushed. Because there are no mechanical grinding tools, there is no wear and tear.
More about
Ball Mills and Agitated Media Mills
In a ball mill, freely moving balls are located in a drum. These balls are set in motion by the drive and the material to be ground is crushed between the balls. In an agitator ball mill, the balls are set in motion by an agitator.
