Properties

The MC 140 Z specializes in high annual mining capacities and large feed sizes. This is helped by the solid double-deck prescreen, which is over three meters long, as well as the powerful diesel engine. The single toggle jaw crusher with its weight of over 50 tons can process feed sizes of up to 1300 x 1000 mm edge length and depending on the feed material reaches capacities of up to 750 t/h.

  • Frequency-controlled vibrating feeder
  • Independently vibrating double-deck prescreen
  • Possibility for external power supply (option)
  • Diesel-electric drive concept

Continuous Feed System (CFS)

For a continuous crusher feed.

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.

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.

Effective prescreening - better results and less wear

For effective prescreening of the feed material, the crushing plants are equipped with an independently vibrating double-deck prescreen. Wear in the crushing chamber is thus reduced by diverting the medium grain directly onto the vibrating extractor. The screen surfaces in the upper and lower deck can be changed easily and safely.

Jaw crusher

Jaw crushers operate according to the principle of pressure crushing. The crushed material is crushed in the wedge-shaped pit between the fixed crusher jaw and the crusher jaw articulated on an eccentric shaft. The material is crushed by the elliptic course of movement and falls down due to gravity. This occurs until the material is smaller than the set crushing gap.
