Granulator with force feeding device - NEUE HERBOLD GMBH

NEUE HERBOLD Maschinen- und Anlagenbau GmbH, D-74889 Sinsheim-Reihen offers a large range of machines and plants for size reduction and recycling of plastics scrap, from production or waste collection. To increase the through-put rate of a granulator used for size reduction of loose, unpressed plastics a force feeding technique was developed.
A screw conveyor is utilized for a technically optimized material feed.

Via conveyor the material is fed in the feed hopper. The transport to the grinding chamber is now no longer only based on the principle of gravitation - in fact the material is now fed to the grinding chamber by one / or more vertically assembled screws. Depending on the required granulator size the number of screws, the rotation speed as well as the drive capacity can vary. A transport screw equiped with a load-dependent control as well as a frequency converter prevents a rotor blockage caused by material accumulation. This results in a throughput rate which is ideal for the processed material. The wear protected design of the transport screw guarantees a long lasting operation time of the machine.

The features of this feeding method offer customers a number of advantages:

Wide range of application areas.

Especially suitable for PET bottle, furthermore are all kinds of plastics bottles, canisters, packing materials from food production, as well as all thin walled hollow containers suitable materials for this feeding method.
Increased throughput rate.
The feed hopper is equiped with a worm gear shaft which enables a continuous material feed
and prevents material swerve at the same time, which results in throughput increase of up to 30%.
Increased efficiency .
The accurate and constant material feed leads to an ideal utilization of the rotor capacity and
supports the efficiency of the entire plant. Furthermore the material fly-out from the feed hopper is reduced which leads to complete processing of the entire material fed to the system.

Increased material feed.

Due to the continuous size reduction of the material, the feed hopper is ready to receive large amounts of material. Compared with a standard granulator feed a material blockage in the hopper is almost impossible, hence the input capacity is maximized.
Decreased sound- and power peaks.
The controlled material feed guarantees a constant, smooth rotor operation and therefore
reduces sound peaks, which could occure by overfeeding. This constant material feed also prevents power peaks during the operation of the machine.

Neue Herbold Maschinen- und Anlagenbau GmbH offers a large range of granulators
which are equiped with force feeding device.

NEUE HERBOLD Maschinen- und Anlagenbau GmbH
We are a German manufacturer of size reduction machines / recycling systems for recyclable materials. Our mainfield is the preparation of plastics but also other recyclable materials such as electrical waste, cable, wooden pallets ,. , , , Our production program here includes the full range of shredding technology (Shredder, Bale Breaker, Screw Shredder, Pipe Shredders, Guillotines, cutting mills, pipe mills, profile mills, hammer mills, pulverizers, impact disc mills) to the Processing Technology in the wet area. Here, to be recycled plastics are prepared after size reduction by adding water (or even partial liquor) in our washing plants. Here are among other complete especially compiled for the customer demand systems available or also the corresponding individual units or as a supplement to optimize existing customer plants. (such. ss separation tank (float / sink tank), Friction washers, intensive washer, drying centrifuge, thermal dryers, dewatering screws, ...) Also we provide aggregates for the recycling of plastic waste and the separation technology for mixed Materials. Conveyors for feeding (conveyor belts, screw conveyors) of the feed material - and removal of the crushed material. We are continually examining in our technical guide our conceptions and when necessary adjustments. We offer our customers the opportunity to experience the capabilities of NEUE HERBOLD in our technical center. Finally, we can offer our customers a quality service and are also capable of your existing machinery and equipment to care for properly and to incorporate new ideas
