Avoid crusher downtime

During routine mobile crushing operations, short-term or prolonged overload situations can occur, interrupting production. To help counter this, Kleemann’s latest-generation Mobicat MC 110(i) EVO2 and MCO 90(i) EVO2 units come equipped with revolutionary overload mitigation features to help keep crushed materials flowing.

The multistage overload system on Kleemann’s Mobicat MC 110(i) EVO2 jaw crusher improves efficiency and safety. If, for example, metal enters the crushing process, the crushing gap (CSS) opens automatically in up to two seconds over the complete gap range. When the overload situation is corrected, the system moves back to the original crushing gap and the crushing process is continued.
Tramp Release and Ringbounce Detection
The Mobicone MCO 90(i) EVO2 cone crusher has two different overload systems installed, namely Tramp Release and Ringbounce Detection.
Tramp Release protects the crusher against uncrushable material such as wood or metal. During this process, the bowl – including the bowl liner – lifts automatically to allow uncrushable material to fall through.
In turn, the Ringbounce Detection system reacts to an excessively high share of fines in the feed material and prevents ‘briquetting’ – i.e. the clogging of the crusher or the sticking together of the material. The crusher’s hydraulic pressure is monitored continuously, and the system reacts as required to prevent latent overloads. Depending on the machine application, Ringbounce Detection can be oriented via the control system to Mixture Mode (output) or Precise Mode (product quality).
By preventing machine damage and production bottlenecks, Kleemann’s overload systems guarantee increased operational reliability.
