Kleemann’s improved jaw crusher increases output
The key product launch for Kleemann at Intermat is its latest mobile cone crusher. Kleemann’s new MCO 9 EVO cone crusher is designed to work with the firm’s recently introduced Mobicat MC 110 Z EVO mobile jaw crusher, also on display at the event. The new cone crusher now closes a gap in the Kleemann model range and carry out secondary crushing, with the primary function typically being carried out by the firm’s MOBICAT MC 110 EVO mobile jaw crusher.
Using similar technology to other Kleemann crushers in the EVO line, the MCO 9 is aimed at customers in the contractor market. It features a direct crusher drive, with electric drives for the conveyor belts. This is said to optimise working efficiency, a feature common to the other EVO models in the Kleemann range.
The 248kW delivered by the drive system is said to be used optimally in crushing, due to the performance-enhanced housing design. A continuous drive power of 160kW is available at the crusher and together with a large stroke, this enables throughput of up to 260tonnes/hour. In addition, the machine delivers a high crushing ratio and produces a final product with a high amount of fine particles when compared with other cone crushers in its class. The crusher features an anti-spin system, which prevents the cone from rotating, reducing wear. A magnet and a metal detector are also available as options, which further increase safety.
Weighing some 30tonnes, the MCO 9 EVO is very easy to transport and can be made ready for operation again quickly and easily. The feed unit can be shifted by a simple slide mechanism from the transport to the operation position. This slide mechanism allows adjustment of the material discharge during operation. The feeding unit can be adapted to the crushing product, preventing wear on one side.
Kleemann has used a proven touch panel control system, which has already been used on other EVO plants and is said to be both easy to operate and intuitive in layout.
Working with the firm’s Mobicat MC 110 Z EVO primary crusher, the two machines are said to deliver an optimum material flow in a linked plant combination. Both machines are equipped with a continuous feed system (CFS), which individually controls the material flow of each plant. Connecting the control systems of each plants allows both CFS units to exchange information. This means that the MCO 9 controls its own conveyor unit through its crusher filling level, but also the conveyor elements of the upstream MC 110. This ensures that the jaw crusher in the primary stage always provides the exact amount of material so that the cone crusher maintains its set filling level, achieving optimal efficiency.
