Abstract
A crusher device for performing a crushing operation, including a hollow part of frusto-conical shape narrowing downwardly, a crusher spindle rotatably mounted coaxial with the hollow part, at least one crusher impeller rotatably mounted on the crusher spindle, and a crusher driving device for rotatably driving the at least one crusher impeller relative to the first hollow part; the at least one crusher impeller comprises a first crusher impeller containing a first crushing blade and a second crushing blade, each of the first and second crushing blades extending radially from the crusher spindle and being fixedly connected to each other at their distal extremities by a blade member. The crusher device can be combined with a milling device providing an apparatus of compact size, adapted for reducing material from a size up to 36000 cm3 to particles having a size below 250 microns.
