Classification & Storage / Crushers

When conveyed material needs resizing

Kopar crushers typically act as primary crushers for metallurgical lumps from waste heat boilers, slags, and dusts. They can tolerate a continuous temperature of 300 °C.

Our roll and rotor crushers are suitable for crushing cloddy or lumpy materials. Waste heat boiler slag, dust lumps, and bottom ash are typical materials crushed with our solutions.

Our crushers are designed to last. When they require maintenance, our specialists ensure that the production halts are as short as possible.

You can easily integrate our crushing solutions with our pneumatic  or mechanical conveying solutions to maximize your facility’s efficiency and productivity.

Different crusher for different materials

Combination of crushers for optimal results

A required crushing process may consist of one rotor crusher, a combination of two rotor crushers, a combination of one rotor and one roll crusher or one roll crusher.

Rotor crushers for coarse materials

Our rotor crushers can treat relatively coarse material with a maximum inlet size of around 300×300 mm. As the typical crushing ratio is ten at a single stage, the material can be downsized to 12 – 30mm. If 12 – 30 mm is not small enough for your needs, you can continue the process either with a finer-bladed rotor crusher, or with a roll crusher, depending on the required final particle size and capacity.

Roll crusher for fine materials

With our roll crusher, it is possible to meet the final size distribution down to 100 % < 3 mm, depending on the material and the capacity. It is adjustable for your customized needs.
