Reliable shredder for individual plastic applications; Customers like to use the reliable and sturdy LRK1000 and 1400 plastics shredders in the plastic processing industry for re-granulation, in-house recycling and volume reduction. Similar to all UNTHA shredders, the LRK plastics shredders can be used as a stand-alone solution or integrated into complex systems. High throughput performance, high availability and a precisely defined end product guarantee high economic efficiency for the user.

The cutting units can be easily and quickly replaced, thereby reducing the shredding machine's downtimes to a minimum. The rugged swivelling pusher with its maintenance-free guide is moved by two hydraulic cylinders, which prevents jamming and thus further increases the machine's availability

We equip our plastics shredders of the LRK- and VR series with a rotor cooling system for materials with a low melting point. This makes them particularly effective with regard to throughput performance.

The reliable and rugged LRK1000 and LRK1400 shredders are popular with companies in the plastics processing industry for volume reduction and in-house recycling.

Like all UNTHA shredders, these machines can stand alone or be integrated into comprehensive systems. High throughput, outstanding availability and consistent particle size ensure an efficient and profitable operation.

During shredding, the load-controlled hydraulic ram (1) pushes the material to be shredded against the rotor (2) which is driven by an electric motor, V-belt and spur gear.

The rotor is equipped with replaceable indexable cutters (3) and shreds the material against the main (4) and secondary (5) stationary cutting bars.

The shredded material then falls through the perforated screen (6); the particle size is determined by the size of the screen. The particles are discharged via an integrated screw conveyor (7) to which additional material handling equipment can be connected.
