redesign of hammer mill to reduce power consumption

Industrial feed manufacturer reduces power consumption

Currently they are using a hammer mill. By adding a SKIOLD disc mill, Viet Duc anticipates to reduce power consumption by 50 % per ton feed manufactured on the disc mill compared to the hammer mill. This is a major saving, due to the fact that electricity costs in Vietnam are equal to e.g. Denmark.
