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.

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

Intuitive control concept SPECTIVE - for simple operation

The easy-to-operate control concept SPECTIVE allows the machines to be operated at a touch panel. All components and functions can be controlled comfortably from the ground.

SPECTIVE guides the operator step by step through the starting procedure. The start screen provides a graphical view of the plant with all adjustable functions at a glance. When the desired function is selected, clear instructions guide users through all operating steps. If a fault occurs, a fault diagnosis appears on the display. Fault localization, the description and remedy tips result in reduced downtimes. The 12" touch panel is resistant to dust and always easy to read thanks to the light intensity and high contrast. It reacts to fingers, pen or gloves.

Continuous Feed System (CFS)

Uniform loading is indispensable for a good product, optimum throughput and low wear.

To ensure that the crushing chamber is always evenly filled, the Continuous Feed System (CFS) monitors the crusher level (jaw crusher and cone crusher) or the load at the rocker and rotor as well as the motor utilization (impact crusher).

Independently of this, the CFS regulates the frequency of the vibrating feeder and prescreen. A backlog on the prescreen is thus avoided and crusher utilization is optimized. When the crushing chamber is free again after overloading, material transport is continued without a delay.

The CFS facilitates the work of the operator because the machine automatically guarantees a homogeneous material flow, thus ensuring optimum loading of the crusher.
