Crumbler

The crumbler produces crumbled feed to control reduction to a specific particle size with a minimum of fines. It's a roller mill with rolls specially designed for crumbling feed pellets, as well as in the flour milling and oilseed processing.
La Meccanica's crumbler is a very solid machine, that allows to obtain a very homogeneous and regular granulometry of crumbled pellet. The cutting rollers are adjustable and spring-mounted to protect against damage which could be caused by foreign objects.
