MR-1500, 2000 & 2500 Single Shaft Shredder
High-throughput for heavy-duty industrial applications, high-availability due to short maintenance times and functionality custom-made for the individual requirements - these were the specifications for development of the "MR" series.
Function

During the shredding process, the hydraulic ram pushes the material loadcontrolled against the rotor. The rotor is equipped with exchangable indexable inserts and cuts the material through the stator blade. The shredded material falls through the grid of the screen that defines the granule size.

The Cutters
The cutters consist of an indexable insert holder and an indexable instert. The indexable insert holder can be easily removed if damaged by foreign material. The indexable insert is suitable for multiple use. A large number of indexable insert sizes and forms are available.

The Rotor
Two different cutting systems with various numbers of cutters are available, thereby ensuring perfect suitability of the machine for individual requirements.

The Control
The machine is controlled by a Siemens SPS S7. All data can be entered and read via an LCD display. The machine is adjusted to the material to be processed by various adjustable program sequences.

The Stator Blade
The stator blade is divided. When foreign material is fed into the machine, parts of the stator blade strip are hydraulically folded away, independant of each other.

The Ram Device
The bearing of the ram device and the obliquely arranged hydraulic cylinders are placed outside the cutters room, so that they are protected against dirt and mechanical impact. The special slide construction allows space-saving design.

The Drive
The machine is driven by a spur gear running in an oil-bath. Thanks to the proven modular design either an electromechanical or an electrohydraulic drive is possible.

Rotor Cooling
When material; with a melting point below 100 degrees Celcius is processed, rotor cooling is used. A coolant is pumped through the rotor and the outside casing of the rotor is cooled.
