Control system for a vertical shaft impactor (VSI) rock crusher to control the cascade ratio

摘要

A control system for a rock crusher, said control system being adapted to control a cascade ratio of said crusher, wherein a portion of material entering the crusher is placed into cascade, and the remainder of said material entering the crusher is supplied to a crusher rotor, the control system including a processing means, said processing means being adapted to receive a throughput signal from at least one throughput sensor, said processing means also being adapted to transmit at least one control signal to at least one control mechanism of the crusher, wherein said at least one control signal or signals are transmitted to each control mechanism to adjust the amount of material entering the crusher rotor to provide a specific cascade ration for said crusher in response to a variable throughput for said crusher.
