Hammer- / cutting mill
High-speed machines for impact/crushing or shearing/cutting Crushing & Milling. Processing of soft to medium-hard and fibrous materials, as well as in the recycling of multi-material components
Our hammer and impact hammer mills are used for Crushing & Milling soft to medium-hard, brittle or fibrous materials. The machines can also be equipped with a rotor with cutting tools, which extends the range of applications to plastic products. Our series also includes machines for small batch grinding.
Our hammer mills and hammer impact mills are equipped with
- Pendulum suspended rackets
- Removable grate baskets or perforated plates to ensure the required grinding fineness
- Replaceable wear plates in the grinder housing
- Inspection openings in the housing to check the beaters and the grate basket
- Crushing & Milling independent of the direction of rotation on some models, i.e. the hammer mill can be operated in both directions of rotation, so the wear parts can be operated up to a maximum degree of utilization.
Areas of application & machine types
The hammer mill is just as suitable as the hammer impact mill for Crushing & Milling soft to medium-hard materials (hardness grades according to F. Mohs 2 – 5). These include, among others: Agglomerates, coal, limestone, gypsum and slag. Our mills are designed for high throughput rates and are absolutely trouble-free in operation.
Hammer impact mills are particularly suitable for the size reduction of coarse material when it comes to achieving high degrees of Crushing & Milling at high throughputs. The hammer impact mill differs from the hammer mill
by the additional impact chamber into which the material is thrown after contact with the beaters.
Tailored to your needs – whether as a single machine or a complete system!
We also manufacture our Hammer- and hammer impact mills in stainless steel according to your wishes or equip them with appropriate sensors for bearing monitoring, speed control or for recording energy consumption.
If you require a complete system with feed/discharge and, if necessary, additional machines such as a screening machine, we are also available to you as a competent and experienced system manufacturer.

Operating behavior & mechanical features
In hammer mills, the material is drawn into the grinding chamber by the hammers suspended from the high-speed rotor. Crushing & Milling is mainly carried out by impact and impact stress in the area of the grate basket. The ground material remains in the grinding chamber until it has reached the required fineness and can pass through the discharge grate.
The final fineness of the finished product is influenced in both types of grinder by changing the grate gap width and the circumferential speed.
In contrast to hammer mills, hammer impact mills have an additional impact chamber in the upper part of the housing. The fed material is caught by the hammers of the rotor and thrown against the impact bars of the impact chamber. The pre-crushed material enters the lower grinding chamber and is mainly re-crushed on the grate basket.
