Drive
- Diesel hydraulic drive with Caterpillar-engines or alternatively with electric hydraulic drive.
Operating
- via switch box and through an upstreamed plant. The secondary shredder has a direct connection to the primary shredder, therefore a priority switch off in case of interferences is possible.
Permanent over-belt magnet
- The magnet is installed in line over the discharge point of the output belt. Metal parts are discharged in moving direction to achieve the best possible metal separation. The measurement of the magnets depend on application size.
Options
- different electric or permanent magnets
Automatic metal separation
- The automatic metal separation consists of a metal detector and a discharge flap. It recognizes ferrous and non-ferrous metal parts in the material. The metal detector is adjustable to variable sensitivity. It is positioned at the feeding belt and controls a discharge flap, which is situated at the end of the belt or before the secondary shredder.
Rotor and screen operation
- The rotor diameter is about 700 mm or 1.000 mm according to the version. The rotor’s working width and the number of fixed knives depend on the type. The screen basket is hydraulically capable and equipped with overload protection. The mesh sizes of the screen basket can be chosen according to the required end product size.
Material discharge
- The discharge belt is approx. 1.000 mm wide and has a discharge height of approx. 3.400 mm 4.300 mm. A magnet roll is build at the end of the belt to separate the uncovered small metal parts like nails, screws etc. from the final material.
Options
- belt cover
- hydraulically adjustable belt height
Additional equipment
- water sprinkling system
- noise absorbing package
Type HAMMERMILL
- Normally we use for our Secondary Shredder a rotor with fixed knives. However it is possible to choose the shredding unit as a HAMMERMILL with swinging hammers.
- Advantages for a rotor with fixed knives
very high performance, extremly low energy consumption, quick and easy maintenance of the tools, low wear costs, equal end product, reduced sawdust
- Advantages for the HAMMERMILL with swinging hammers
longer service intervals, insensitive to foreign bodies, massive hammers
