The hammer mills are of robust construction and are, depending on the model, designed for a certain excess pressure so as not to cause any personal injuries in the event of possible deflagrations within the mill. Of course, this is also taken into consideration for the following conveyors.
An additional pressure relief is provided for the safe control of possible excess pressure within the range of the hammer mill. Depending on the model and the incoming material, the hammer mills have a throughput of 5 - 20 t/h at a motor power of 75 - 450 kW. The hammer mill beaters used are ensured service lives between 2000 and 4000 h with their hard surfacing.
