Manufacture of the GNR PDK01 Primary Impact Crusher Completed for a Stationary Plant in Novi Pazar

We have completed the manufacture of the GNR PDK01 primary impact crusher for a stationary crushing plant to be installed in Novi Pazar, Serbia. On the stated stone and mineral materials, the crusher runs at an average capacity of 250-500 tonnes per hour.

In a quarry processing limestone, the biggest gain from using an impact crusher at the primary stage is that it delivers a high reduction ratio in a single step. Because the run-of-mine material is broken down considerably at the first stage, the downstream crushers can be selected lighter.

The limit of this choice is set by the abrasiveness of the material.

In abrasive rock the impact elements wear quickly, and money spent on wear parts wipes out the gain on the crushing side. For that reason it is not possible to decide which crusher type to use before a quarry analysis has been carried out.

The fact that the crusher was built for a stationary plant also shapes the design. With no transport constraints, there is no limit on body weight, which creates an advantage in controlling vibration and balancing the rotor. When part of the vibration is passed into the ground, the fatigue load the body is exposed to is reduced as well.
