Uni shredders - Robust two-shaft shredder
The Uni shredder effectively shreds coarse particles such as fibers, wood chips, plastic, membranes, and fabric remnants etc., ensuring stable operation in the subsequent process. The Uni shredder homogenizes the medium to prevent blockages in downstream pumps.
Operation
Blades mounted on two hexagonal shafts act as rotors rotating at different speeds. This creates a relative movement between the blades, ensuring efficient shredding/cutting function. The degree of shredding can be varied by the number of teeth, rotational speed, and blade configuration.Thanks to the service-friendly MIP (Maintenance In Place) design, all blades etc. can be quickly replaced through the service hatch.
Technical Configuration
- Service Cover- All normal wear parts can be replaced through the front cover while the chopper is installed in the piping system (MIP)
- Protective Plates- The pump casing is protected by easily replaceable axial protective plates
- Knives- The chopper is supplied with a variety of knife configurations with fine or coarse teeth depending on the task at hand.
- Shaft Seals- Single mechanical front-mounted shaft seals with oil cooling ensure trouble-free operation
- Ripper Housing- The ripper housing can be supplied in gray cast iron - Ductile cast iron - Stainless steel or Duplex
- Quench for Shaft Seals- The oil chamber behind the shaft seals ensures optimal lubrication and cooling of the seals under all conditions
- Heavy-duty Gearbox- The gearbox is equipped with extra heavy-duty shafts and large bearings that ensure a long service life, even under the most demanding conditions
General structure
Various rotational speeds of shafts and knives provide optimal cutting and self-cleaning results.
Chopper Plus with Integrated Stone Trap
Portable Unit
In the above example, the chopper is mounted on a base frame for easy and quick transport with a forklift truck.
Space-saving and service-friendly
The compact motor with angular gear reduces the space required by the unit. Furthermore, the chopper is mounted at an ergonomically optimal height.
Fast drainage of stone trap
The stone trap is easily and quickly emptied by opening the drain valve. Debris is easily and quickly removed through the large emptying door at the end.
Numerous design & configuration possibilities
Uni-chopper + lobe pump
The chopper and pump have the same design which provides an elegant installation
Stone trap + Uni chopper + centrifugal pump
Hard foreign objects such as stones and metal can often be a problem for twin-shaft shredders. By installing a stone trap in front of the chopper, foreign objects are settled in the stone trap to avoid blockages in the chopper.
90° connections
Connections are adapted to the existing piping system. Here is an example with upward connections
Vertical Unihacker + lobe pump
Suitable for low-viscosity fluids coming from screw conveyors or belts
Feed screw + Uni chopper + lobepump
It is often necessary to install a feed screw in front of the chopper so that the medium is pressed through the chopper. Suitable for e.g. meat, vegetables, and similar items that are not liquid before passing through the Uni chopper
Uni-chopper + feed screw + lobe pump
Example where a partial stream is chopped before being fed to the feed screw and mixed with another medium.
