KEMROC Spezialmaschinen GmbH

Technology

The experience gained from many years of cutting rock has gone into the design of the cutter wheels, drums and chains. They are designed to give maximum cutting performance with minimum wear costs.

Well proven cutting technology

When grinding with round attack picks, each tool penetrates into the rock along parallel paths and breaks material out from the space between the paths.

The selection of picks and boxes, as well as the design of the pick pattern, are part of our continuous product improvement.

The cutting rate depends to a large degree on the uniaxial compressive strength of the rock being cut. Other significant factors affecting production rates include the hydraulic pressure and flow that the excavator is able to supply to the attachment, as well as the stability and weight of the excavator.
