CONTROL OF CRUSHING CIRCUITS WITH VARIABLE SPEED DRIVES

Jan 01, 2005 Crushers play an important role in the comminution of minerals and the control of its operation can lead to an increase of the plant throughput and efficiency. This work presents a simple but effective method for controlling a crusher circuit by acting over the feeder and the speed of the conveyor belt carrying out the mineral up to the crusher.

Optimal feed arrangement — SRP

Coupling a variable speed feeder with the feed-level sensor will help you maintain a constant material level in the hopper. A pre-crusher surge bin with a low-level monitor connected to the control system can also ensure proper feeding. Spider-arm placement.

Conveyor Drive: Feeder Drive for Rock Crusher/Pick Breaker

The unloaded pick motor draws a low current that causes the controller to call for a maximum conveyor speed. As product is delivered to the conveyor inlet and up to the breaker section, pick/crusher motor current increases, reaching a trigger point at which the feeder conveyor drive begins to reduce conveyor speed.

Apron Feeders Mineral Processing & Metallurgy

May 31, 2016 Feeders are driven by less than one horsepower up to 40-hp motors, depending on feeder size and expected load. The main point to consider in selecting a feeder is that it must provide an even flow of material to the primary crusher. The size of the feeder and its speed should provide a capacity 25-35% greater than the capacity of the crusher.
