Hammer and impact hammer mills
High-speed machines for impact shredding and impact crushing. Processing of soft to medium-strength materials and recycling of multi-material components.
Our hammer mill can be used for Crushing & Milling soft to medium-hard, brittle or fibrous materials.
The machine can also be fitted with a rotor with cutting tools so that the range of applications can be extended to include plastic products.
The hammer mill has the following features
- A replaceable rotor with
- Pendulum suspended rackets
- or cutting blades, which can be replaced individually.
- Easily removable grate basket or perforated plates to ensure the required grinding fineness
- Replaceable wear plates and crushing/cutting bars in the grinder housing
- Housing door for easy inspection/cleaning of the grinding chamber and for changing from beaters to cutting tools
- Frequency inverter-driven direct drive.
- Tamper-proof feed hopper
- Collection container can be removed via quick-release fastener
- Instead of the collection container, a hopper with suction connection can also be used as an option. A vacuum cleaner and cyclone can be used to achieve higher throughput rates, particularly with very light products such as chamfers and plastics.
Innovative app control
- Standard Operating Procedures (SOP)
- Variable speed
- Calling up the operating instructions
- Direct spare parts inquiry
- Sample/machine data can be exported via csv file
- Updateable app and firmware
Areas of application & machine types
The hammer mill is suitable 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, metal chips, recycling products. Our mill is designed for Crushing & Milling larger sample quantities and is absolutely trouble-free in operation.
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.
Talk to us – we will be happy to advise you!
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.
