Features and benefit

Features

The unique design of the cutting area, the variable cutting frequency,the continuously adjustable rotor speed and the optimal selection of screen sizes, all together secure high rates of homogenous output.

The shaft positions in the twin shaft M&J FineShred secure a self-feeding effect, eliminating the need for additional pushers. Along with the geometry of the 12-edged shaft, which minimizes the risk of material wind up of the shafts, this prevents heat development in the machine.

Easy maintenance and short downtime

With the new design feature that allows the two shafts to be moved apart, access to the shafts and the cutting tables has been improved greatly. This makes maintenance easy, which minimizes downtime.

Benefits

Our range of FineShredders has been developed to serve the needs in the recycling industry and work with either a pusher or two shaft self-feeding systems. The 3 different solutions share certain key benefits like:
• Homogeneous output from 10-100 mm
• Minimal fine particles
• Minimal dust emissions
• No heat generation
• Easy maintenance

Drive and screen

Drive
The hydraulic system consists of a variable pump with power control, an integrated feed pump and a hydraulic motor mounted on each shaft. All together a “state of the art” double hydrostatic system, providing the maximum output and the most reliable performance available.
Screen
Due to the precise cutting of the material the strain on the screens is minimal and the design can therefore be made in very thin materials. Typically screens can be made in 3 - 6 mm plates. As there is not pressure on the screen the open area can be optimized and secure a high output rate. Discharge of the granules can be executed either using screw conveyors or belt conveyors.

Multi-edge rotor and hydraulic drive

Two counter rotating shafts fitted with knives specially selected for the individual applications ensure a high degree of flexibility of the units. The unique design of the cutting area ensures minimal friction on the shaft. In combination with the continuously adjustable rotor speed, the variable cutting frequency and the optimal selection of screen sizes a very homogeneous output with a minimum content of fine fractions can be achieved.


The hydraulic drive of the shafts guarantees an impact resistant and resonance free power transmission. All together a minimum of wear and energy consumption is secured.
