New EVO2 generation guarantees higher operational reliability

June 1, 2022  By Wirtgen Group

In rock and stone processing, during the crushing process various short-term or prolonged overload situations can arise. The overload systems of the MC 110 EVO2 and MCO 90 EVO2 pursue an important goal: Increase in the operational readiness of the plant in a sustainable manner by guaranteeing a crushing process that is as continuous as possible. Both crushing plants are equipped with mechanically and software-supported overload systems.

With its multi-stage overload system, the jaw crusher MOBICAT MC 110(i) EVO2 provides more safety with uncrushable material. If, for example, metal enters the crushing process, the crushing gap (CSS) opens automatically in up to two seconds over the complete gap range. The crusher itself does not have to be stopped during the temporary overload situation, which means that the crushing chamber is empty and manual clearing of the crusher is not necessary which saves work and time. When the overload situation is corrected, the system then moves back to the original crushing gap and the crushing process is continued. The pressure plate installed as a predetermined breaking point is preserved. The consequences are reduced downtimes and increased crushing capacity.

The cone crusher MOBICONE MCO 90(i) EVO2 has two different systems installed. The overload system “Tramp Release” protects the crusher against uncrushable material such as wood or metal. The bowl including the bowl liner lifts automatically to allow uncrushable material to fall through. The “Ringbounce Detection”, on the other hand, reacts to an excessively high share of fines in the feed material and prevents “briquetting” – which means the clogging of the crusher or sticking together of the material. Here, the hydraulic pressure of the crusher is monitored continuously. The system reacts as required and thus prevents latent overloads. Depending on the machine application, the “Ringbounce Detection” can be oriented via the control system to output (“Mixture Mode”) or product quality (“Precise Mode”).

By preventing machine damage and thus production downtimes, the overload systems from Kleemann thus guarantee increased operational reliability for the users.
