With linear feed rate adjustment, the UN-COALER® provides constantly uniform discharge into the crusher, assuring maximum efficiency and extended wear life on the crusher elements.
For feeding systems with higher amplitudes, ratios of up to 8 : 1 can be required. Feeder Control Systems. As a vibrating feeder is a relatively simple piece of equipment, the control requirements are small. Once a feeder is set up to perform it's intended function, control requirements are usually limited to 'stop' and 'start'.
Single-roll crushers may be either feeder-breakers, or conventional rolls. The rolls on feeder-breakers resemble the cutting head of continuous coal mining machines. Feeder-breakers have very high capacities of up to 2000 tons/h, and are mainly intended for oversize control rather than achieving a high degree of size reduction.
