Vibrating Grizzly Feeders are devices that sit below a hopper that is filled with mass production. The feeder is driven by an out of balance electric motor. The motor is controlled by a soft start speed controller, which controls the speed of the engine from zero to full rpm. When the motor starts it results in the feeder trough to vibrate causing the product on the trough to move away from the hopper in a controlled way along the trough to crusher becoming fed.
For Vibrating Grizzly Feeders to function at maximum efficiency, they ought to be matched with the right program and be properly maintained. Correctly maintained feeders create for cost effective and efficient operation.
Feeders are designed to perform specific jobs. If they are not used with the ideal program, then this will cause them to break up or malfunction, which could cost your business a lot of money. WPE Process Equipment manufacture high quality vibratory screening machine in Australia. When the right feeder is utilised, and proper maintenance procedures are followed, then grizzly feeders may last for several years. When things go wrong, it is usually because the feeder isn’t the right one for your job and it’s either too brief or not adequately wide or heavy duty.
Length of the Feeder
Though might not seem, length is a significant factor in feeder’s operational efficiency. The length of feeder, even if adequate, allows for the material to be rolled onto the horizontal surface of the pan and not to the grizzly bars, which reduces the risk of material getting wedged between them and causing damage.
Longer feeders also allow the material to stratify, therefore decreasing the bed thickness before the material reaches the bars. This results in better efficiency and quick removal of fine material that does not need primary crushing.
Width of this Feeder
Width is selected based on various factors such as feed rate, the size of the material to be fed, as well as the magnitude of the crusher being fed.
Heavy Duty or not
The choice for a feeder to be heavy duty or not is frequently based on the dumping method i.e. truck dump or loader dump. Truck dump involves very rough dumping of big sized feed in 30-40 feet straight onto the pan of this feeder. Such an impact can severely harm the unit unless the unit is a sufficiently heavy duty, reinforced with thicker steel plates on the pan and sides. Long and heavy springs with long displacement would be used to soften the impact without coils becoming collided.
On the other hand, loader dump entails softer dumping with smaller top-size feed that places a far less effect upon the feeder. Thus, the feeder doesn’t need heavy duty design.
