PDK-70 Primary Impact Crusher

FEATURES ROTOR

Rotor is the key component in the crushing process and together with shaft and bearings forms the heart of the crusher, that’s why we have ensured that the rotor is robust and efficient to handle up to 1 m3 large lumps. Rotor is manufactured from solid-cast steel with heavy duty rotor discs, essential for delivering the high inertia required for optimum crusher performance. Solid forged steel shafts are precision machined for assembly. Rotor shaft is supported on grease lubricated, self aligning large spherical roller bearings with labyrinth type seals for extended life. The bearings have a pedestal mounted split pillow block housing for easy maintenance. The open rotor design additionally provides the ability to handle re-enforcing bars etc. in recycling applications

Designed to process large feed sizes and high capacity crushing, Fabo PDK impact crusher is suitable for primary processing of limestone materials or medium hard materials. It is very compact and it can achieve high performance and excellent cubicity of the crushed product.

The PDK crusher can replace the CLK jaw crusher when the feed material is particularly not hard and abrasive, because in addition to the high particle size reduction, it provides a higher percentage of fine grain. The maximum feeding size is designed depending on the size of the feeding opening

Impact bars in manganese steel casting are very wear resistant and can be of different types which have different profiles depending on the requirements and nature of the material being processed. The hydraulically adjustable rods can be approached or removed from the rotor to obtain the correct particle size distribution curve, allowing to keep the final product constant in time. The same hydraulic system also allows the machine to be opened for maintenance and inspection.

Advantages:

• excellent cubical shape of crushed material
• excellent reduction ratio
• high quality material production
