thyssenkrupp Offers Multirok Vertical Shaft Impactors

Multirok vertical shaft impactors, manufactured by thyssenkrupp can be used flexibly in stationary, semi-mobile and mobile plants. thyssenkrupp also carries out intensive research and development work to continuously optimize the proven concept.

thyssenkrupp copyIn vertical shaft impactors, the material is fed centrally into the rotor from above. The centrifugal forces inside the rotor throw the material against the sidewall, resulting in a highly cubical product.

Multirok impactors from thyssenkrupp are available in two sidewall and rotor variants: the sidewalls can be equipped either with anvils or with a material bed. For the rotor, there is a choice of open or closed configuration. The optimum design is selected on the basis of the feed material and the specific customer requirements.

thyssenkrupp offers its Multirok vertical shaft impactors in three sizes: Multirok 7 for throughputs of up to 200 tph; Multirok 9 for throughputs of up to 300 tph; and Multirok 9 Duo – which has two drive motors – for throughputs of up to 400 tph. The product size is mainly influenced by the rotational speed of the rotor. The Multirok can be equipped with a variable frequency drive to adjust the rotor speed. This ensures quick and easy product changes during operation.

Maintenance is a key issue in the operation of vertical shaft impactors. Multiroks from thyssenkrupp are of robust design and offer a long service life while ensuring easy access to key components. The rotor liners and liner plates on the rotor and the anvils in the anvil ring can be accessed and replaced simply via a hydraulically removable housing cover. All wear parts are made of highly wear-resistant materials.

The versatility of the Multirok does not end with the configuration of the sidewall and rotor. Operators can respond at any time to changes in operations and subsequently switch between anvil ring and material bed and between open and closed rotor designs. All Multiroks are also equipped with automatic lubrication units for the drive shaft roller bearings to ensure reliable lubrication.
