Product catalog summary
Design Features
The MHC Twin Shaft Breaker is designed to crush soft and sticky materials like marl, clay, shale, and coal. It is available in two teeth configurations suitable for ball mills and vertical mills, ensuring optimized product size. The type designation, such as MHC 630 x 1.45, indicates rotor shaft spacing and length.

Power Consumption and Wear Reduction
The breaker consists of a frame and two rotors with toothed discs. The cutting action of the teeth keeps specific power consumption low. The rotors operate at low speed, minimizing fines generation and reducing wear on replaceable parts.

Stable Operation
Cleaning teeth inside the breaker frame prevent rotor clogging. The drive station includes an electric motor, pulley drive, and fluid coupling, designed to start even with material on the rotors.

Maximum Protection
If non-breakable material is trapped, the fluid coupling slips, and a speed monitor stops the motor, sending a signal to the control room. If this fails, a mechanical switch activates, and a melting plug releases oil from the coupling, stopping torque transmission.

Installation
The breaker is delivered as a single unit with the drive station, grease lubricating unit, and barrel pump. It is installed in the chute, and power and control systems are connected.

Main Features
  • Ideal for sticky materials
  • Low energy consumption
  • Minimized fines generation
  • Easy maintenance and inspection
  • Automatic lubrication systems
  • Compact design


Adjustments and Maintenance
Adjustments can be made to accommodate harder materials or higher output needs by altering drive pulleys or rotor synchronization. Maintenance is facilitated by a grease pump and easy monitoring of wear parts. The breaker can be moved for maintenance using supplied tools and lifting yoke.

Technical Specifications
Various models are available with different dimensions and weights, suitable for specific mill types and output sizes. Key dimensions and weights are provided for each model.

Adjustments and maintenance Changing operating conditions require adjustments When the crusher has been running for some months or some years, the raw materials may become harder to crush or a higher output may be needed. The MHC Twin shaft breaker can then be adjusted in several ways. The size of the drive pulleys may be altered to achieve a higher throughput or a higher torque. The condition of the wear parts (toothed discs in rotors and cleaningteeth) is easily monitored by taking a glance inside the breaker. The breaker is moved into maintenance position by lowering the wheels at the corners....
