PTH-Series - Perfected fine shredding

PTH Hammer mills
Fine crushing of the heaviest materials

The hammer mills of the PTH series are designed for crushing and upgrading the heaviest materials and are often used for grinding limestone, phosphates or gypsum. However, the machines are also suitable for other applications, such as glass recycling.

Our hammer mills
Robust construction

The mill housing of the hammer mill is made in a sophisticated welded construction with two hinged parts, which can be opened hydraulically. The interior is armored in the wear zones with wear-resistant Hardox sheets or castings, and the rotor disks are also made of a wear-resistant material suitable for hammer mills. The drive is provided by a motor pulley and a mill V-belt pulley and can be equipped with different power levels. Depending on the drive power of 7.5-300 kW, the hammer mill has a throughput of up to 60t/h and a unit weight between 2t and 6t. Due to the various options and extensions, the right machine can be found for every feed material and desired end product.


Powerful - Compact - Efficient
The right machine for your requirements

Depending on the desired feed size, the material and throughput or even the final particle size, the right machine will be found for your requirements. We would be pleased to help you with the selection and conceptual design of your machines and support you with our more than 25 years of experience with hammer mills.

Impact mill meets hammer mill
For perfect comminution of a wide range of materials

The combination of impact mill housing and hammer mill rotor is particularly suitable for applications such as the separation of PVB film and glass for car windshields or safety glass. By using different beaters, hammers, knives or blades in the rotor, we can ensure perfect size reduction of a wide range of materials and products. The wearing parts in the PTKSH are made of chrome castings and ensure cost-efficient and low-cost production.


The 2-rotor hammer mill
For maximum degree of crushing

This hammer mill has 2 rotors, which in combination with each other provide a maximum degree of comminution. The target of this machine are final particle sizes below 1 mm.

A hammer mill as shredder
For a wide range of products and applications

The PTH SI shredder was developed on the basis of our hammer mills. This is mainly used in the shredder light fraction or also in the processing of electronic scrap. The rotor can be equipped with various different hammers and beaters, and the shredder has a 240° grate basket through which the shredded material reaches the outlet. The size of the end product can thus be determined by different sized grate baskets. All in all, a shredder for a wide variety of products and applications!

Primary crusher + hammer mill
A powerful combination

These two machines are often used together, since the impact mill alone cannot guarantee ultra-fine comminution and the hammer mill is limited by the feed size of the material. Depending on the requirements and tasks, impact mills and hammer mills can be used in a wide variety of sizes to break down feed sizes of over 1000 mm to less than 1 mm in just 2 steps. The sizes of the machines are mainly determined by the factors feed size and throughput per hour.
