Features

• Plant linkage for perfect combination versatility: The line coupling option allows special KLEEMANN plants to be coupled with one another. The crushing process between the crushing plants is automatically controlled so that material is always conveyed with maximum efficiency through the machines. A probe is installed at the crusher discharge conveyor of the upstream machine, which monitors the filling level of the feeding unit of the downstream machine. When the filling level reaches a defined height, the output of the upstream plant is temporarily reduced or feeding is switched off, thus effectively reducing the overfilling of individual machines and ensuring that machine utilisation is always ideal. The feed control Continuous Feed System (CFS) also guarantees optimum utilisation of the crusher.

• Innovative diesel-direct electric drive concept - impressive performance with the best possible consumption values: The crushers of the EVO line have an innovative "diesel-direct electric" drive concept and are powerful and economical at the same time. An efficient and powerful diesel engine drives the crusher directly via a fluid coupling. The drive technology thus impresses with extremely low efficiency losses and maximum output directly at the crusher. All secondary drives – for example, for prescreen, vibrating chutes and conveyor belts – are driven electrically. The fluid coupling guarantees high operational safety – for operator and machine.

• Cone Crusher: Cone crushers crush the feed material in a circulating opening and closing crushing gap between bowl liner and crusher cone. Opening and closing also takes place simultaneously on the opposites sides of the crushing chamber.

• Continuous Feed System (CFS): Uniform loading is indispensible for a good product, optimum throughput and low wear. To ensure that the long crushing chamber is always evenly, the Continuous Feed System (CFS) monitors the crush level (jaw crusher and cone crusher) or the load at the rocker and rotor as well as the motor utilisation (impact crusher).

• Ring Bounce Detection: During ring bounce, a movement is created between the bowl and the main frame of the cone crusher as a result of excessive crushing forces. This is triggered by feed sizes that are too large or small, an excessive fine content or the continuous feeding of uncrushable material. To protect the crusher, software continuously monitors the hydraulic pressure of the crusher overload system and reacts when necessary with two modes: Mode 1 – PRECISE MODEfor the production of grit: the machine stops feeding if ring bounce is detected; the operator receives a fault message and can adapt his process. This mode assures that no impermissible oversize grain is produced and the machine is protected against crusher damage. Mode 2 – MIXTURE MODEfor the production of mixtures: in this mode, the machine adjusts the crushing gap - without intervention of the operator - automatically to prevent ring bounce. After a defined period without ring bounce, the gap is closed again to keep the share of oversize grain as low as possible.
