Grinding barley-rich pig feed with hammers and rollers

Particle size in pig feed matters. This article describes how the particle size structure of a pig feed mixture with a high barley content can be optimised by means of stage grinding with a hammer mill and a downstream crushing roller mill. Animal nutrition research findings have shown that an increased content of fines in the pig feed meal can have a negative influence on the health and performance of the animals. This is caused by the formation of gastric ulcers in the animals, by a non-optim
