Recycling
-
Our product range for the RECYCLING industry consists of shredders, bag openers, screens and conveyor systems for the mechanical treatment of solid waste products.
Depending on the input material and the application, we offer both slow speed pre-shredders (RAPTOR, DINOSAURUS®, TRIREX) and high speed calibrating shredders (WOODHOG). Bag openers (BAGRIPPER®) open up collection bags and tangles of waste, release the contents without damage and dose the material into the downstream sorting plant.
Next to that, we build screens for the correct separation of fines (ECODISC®) or for the removal of oversized parts (SCALPEL) to avoid clogging in the subsequent separation line. Finally, we build turnkey shredding and screening solutions completed with a total range of modular conveyor systems. 
DINOSAURUS
-
The DINOSAURUS is a stationary, slow speed, double-rotor shredder with hydraulic or electric drive.
The two hydraulic driven rotors are independently programmable and shred the input material through a central knife and two lateral knives. The different types of central and lateral knives that can be used, together with the unlimited adjustment possibilities of the PLC, turn the DINOSAURUS into the most flexible shredder available on the market. This enables us to adapt each shredder to the specific requirements of our customers and to the required product specifications for their production processes.
The individual control of the shredding rotors also ensures a regular and adjustable dosage of your waste stream, avoiding bridging and winding of the material to be shredded.The DINOSAURUS pre-shredder is available in the following models, depending on the capacity to be processed and the desired setup:
- DINOSAURUS 1800S
Stationary, slow speed, double rotor pre-shredder with electric power pack. This model has shorter rotors and less power.
- DINOSAURUS 2600S
Stationary, slow speed, double rotor pre-shredder with electric power pack.
- DINOSAURUS 2600T
Mobile, slow speed, double-rotor shredder on a semi-trailer chassis, with integrated diesel engine power pack.
- DINOSAURUS 2600R
Mobile, slow speed, double-rotor shredder on tracks, with integrated diesel engine power pack.
- DINOSAURUS 1800S
TRIREX
-
The TRIREX is a stationary, slow speed triple-rotor shredder with hydraulic drive.
Three rotors with individual hydraulic drive shred the input material in both directions of rotation through two central knives and two lateral knives. The rotating speed is continuously adjustable per rotor.
Throughput varies from 15 to 150 tonnes per hour, depending on the input material and the desired output size.
The heavy-duty construction and the powerful hydraulic drives guarantee a high availability at low and manageable operating costs over the long term, even in continuous operation and under extreme conditions. The shredding table is virtually insensitive to unshreddable material.
The TRIREX is further characterised by its large square input hopper. This makes the machine particularly suitable for bulk loading by a large-capacity polyp grab. The wide cutting table avoids bridging.
BagRipper
-
The RENTEC BAGRIPPER is a totally new approach to the classic bag ripper or bag shredder, in which RENTEC remains faithful to the qualities for which it is famous.
The machine differs in several aspects from classic bag openers / bag shredders :
- no cutting process
- totally insensitive to intruding material
- perfectly constant output => higher separation efficiency, higher sorting quality and higher availability of the sorting plant
- opening degree > 99% => higher recycling rate and reduced share of residual material
- no damage to the recyclables => no creation of additional fines
- gigantic capacity
- minimal maintenance and cleaning
When sorting separately collected lightweight household packaging (density of 80 kg/m3), the BagRipper eDrive (2 x 55 kW) can process over 25 tons/hour. The intelligent PLC can be adjusted to any desired capacity, thus feeding a perfectly constant and dosed flow to the (automatic) sorting plant. The machine is also able to treat the more elaborate plastics (films, tapes, ribbons ...) of P+MD (Belgium).
RAPTOR
-
The RAPTOR is a stationary, slow speed, monorotor shredder with hydraulic drive.
One hydraulically driven rotor, with a diameter of 1 meter, shreds the input material in both directions of rotation on two bolted side combs. The side combs can be different on the left and right side to achieve a coarser or finer end product according to the preferred rotating direction. The operator can determine the rotating speed, direction and time per rotating direction according to the specific application via the control display. In case of overload, the rotor switches to the other rotation for an adjustable time.
This shredder is particularly suitable for the shredding of household waste and biodegradable waste streams.The RAPTOR pre-shredder is available in following models, depending on the capacity to be processed and the desired layout:
- RAPTOR 2600S
Stationary, slow speed, mono-rotor shredder with electric power pack (90 kW - 132 kW - 160 kW).
- RAPTOR 2600T
Mobile, slow speed, mono-rotor shredder on trailer chassis, with integrated diesel engine power pack.
- RAPTOR 2600S
Woodhog
-
RENTEC installs the first 4064 WoodHog in Belgium.
This super-duty, high-speed grinder processes post-consumer wood waste to the specifications of the chipboard industry and the green energy suppliers.
The shredder is equipped with a 250 - 315 kW electric motor with frequency control. This offers following advantages :
- total control of power surges during start-up
- adjustable rotor speed to adapt the size of the output material to the customer's specifications
- controlled reduction of the rotor speed to a standstill within 2 minutes after switch-off
The rotor is suited for 100 mm thick, 25 kg heavy, both swinging and fixed hammers. These are equipped with dismountable and weldable hammer tips. The calibration basket consists of individual welded screens that can be exchanged according to wear or desired final product size.
A ballistic ejector is mounted in the feed hopper which allows solid metal jamming material to leave the grinding chamber immediately in order to avoid further wear and damage.
