Abstract
In a grinder-mixer apparatus there is provided an improved dust collection system which draws off air and suspended finely ground crop particle materials from the front side of the hammermill, transfers it to a cyclone separator where the particulate matter is separated out and fed back into the top of the hammermill for further grinding and ultimate delivery to the mixing tank.
