Hammer mills

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.

Applications of a hammer mill

The optimal solution for every application

Whenever a final grain size of 1 mm and smaller is to be produced, in many cases the most economical solution is to use a hammer mill. Hammer mills are often used for grinding limestone, phosphates or gypsum, but are also suitable for other applications such as glass recycling. Due to the many designs and operating modes of different models of hammer mills, we can offer and install the optimal solution for your application in any field of use. On request, the hammer mills can also be integrated into existing plants in order to generate a higher throughput with more economical production at the same time.

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.
