Grain crushing mill assembly - has rotor on vertical shaft carrying impact elements with forked ends

摘要

The grain crushing mill consists of a housing (1) in which the grinding space (2) is provided by surrounding perforated surfaces (3) and (4). Between the cylindrical surfaces (3) and the housing wall (1) an annular gap is provided allowing the grain particles ground to the required size to leave the grinding space. The grinding tool (8) is fitted on a vertical shaft (6) which is seated in ball bearings (14) mounted in a bearing housing (5). The material is fed into the crushing mill through a hopper (16) connected with the grinding space (2) by a coller (15) with an adjustable sliding gate (18). The shaft (6) carries on its lower end a hub (12) on which a rotor disc (9) is fitted carrying a number of impact elements (10, 11) with ends bent in opposite directions to form a fork-like shape.
