Plastic Processing & Recycling Equipment
Granulators, Shredders, Washers, and more
Neue Herbold, the German equipment manufacturer, is a global specialist in plastics recycling that offers a full range of machines including shredders, granulators, grinders, pulverisers, hammer mills, guillotines, washers, and dryers.
In addition to above, we also supply other peripheral devices, for example, conveyor belts for material feeding or for the forwarding of shredded material to the following units: pre-wash screws, suction units, cyclones and fines separators.
The ZRM series of two shaft shredders is characterised by their low shaft speeds, which can be either electrically or hydraulically powered.
The HZR range of pipe shredders can process up to three Tonnes per hour, although actual throughput is determined by the impact strength and wall thickness of the pipe together with the screen size.
The RL series has been specially designed for the efficient processing and recycling of high-volume Styrofoam and insulation material.
The SB range of equipment is designed to process large items such as pallets and cable drums as well as for breaking up baled material.
The Neue Herbold Guillotine Shears are specifically designed for the processing of special wastes such as fiber-bales, tapes, fishing nets, innerconnected adhesive films as well as large chunks or even rubber bales.
The HM range of hammer mills is available with different tool designs and housings to permit the high-speed processing of different materials.
Neue Herbold offers a range of washing lines that may be specially designed to meet customers’ requirements. Washing lines can include hot or cold wash, can be suitable for food grade applications, can be designed to handle glue separation and are able to be specified to handle films or rigids.
The FW series of friction washers are used to thoroughly wash plastic material including film flakes and bottle flakes (e.g. PET) and other rigid plastics.
Material which has been washed and size reduced using a wet granulator passes to a dewatering screw which separates out the water containing the dissolved contamination.
The pre-wash screw has been specially designed to remove foreign bodies from the material and for wetting the material with water. This is primarily intended for the recycling of film for pre-treatment and to protect the intensive washer.
The pre-wash drum consists of a cylindrical separation level with material discharge as well as a conical feed hopper for the recycling material as well as the water.
The Neue Herbold TM range of mechanical dryers are used as a downstream component following a washing process. It is used for surface drying of the washed material, primarily for film flakes, granulate from PET bottles and other rigid types of plastics.
Neue Herbold has designed their T series stage dryers specially for the gentle drying of PET plastic regrind. They are suitable for removal of surface moisture from the plastic granules. Depending on the temperature, size and structure of the product, a residual surface moisture content of about 1 to 2 percent, by weight, can be achieved.
The Neue Herbold TT range of thermal dryers are intended to be used downstream, after a mechanical dryer (TM Series). They are designed to achieve a final material moisture of 3% or less. Following the drying process the material is blown into film silos (FS Series) or into big-bags for further treatment.
Neue Herbold Holding Silos / Film Silos FS Series are developed for the intermediate storage of material thas does not flow easily.
One major component of a recycling plant for plastic scrap is the storage of valuable substances.
Neue Herbold designs and manufactures tailor made suction units and material transport systems to suit specific, customer oriented, applications. These may comprise venturis, blower systems (MFT Series), cyclones, gravity separation systems etc.
When it comes to the density separation of plastics, primarily for film flakes, granulate from PET bottles and other rigid types of plastics, Neue Herbold offers their TB range of Separation Tanks. Depending on the application, the required polymer can be floated to separate it from other materials. The standard separation tanks are manufactured from stainless steel.
The Neue Herbold HS range of fines separators are designed for the removal not only of the dust from rigid granulate but also can be applied for removal of dust and fluff (for example in HDPE blow moulding waste or injection moulding waste). The separated fine material is discharged into a container to ensure a dust free environment.
Neue Herbold has designed their ZS range of cascade (or zig-zag) sifters for the density separation of various types of dry materials, for example materials that must be separated for environmental reasons, separation for improved quality or separation prior to further processing. To achieve the best results, it is necessary to look at the specific density, form, surface characteristics and size of the material being processed.
