Cutting drums for Surface Miners

For each application, we are making every effort to optimize the cutting performance while at the same time maximizing the service life and minimizing operating costs. To achieve this goal, the cutting drum and toolholder system are given a heavy-duty design tailored to performance requirements in accordance with the type of rock to be mined, rock hardness and material gradation.

Depending on the material to be mined, different drum and pick configurations are available for each type of machine. Based on the material properties and rock hardness, the optimum solution in terms of the drum diameter with picks, pick spacing, holder bases and additional special equipment for increased wear resistance is determined in close cooperation between the customer and WIRTGEN experts.
