Agglomerators, densifiers, plastcompactors

The densifier model HV is a system to densify flakes and regrind of low bulk density - e.g. shavings, film, fibers and foam - with. The agglomerate has a higher bulk density than the original flakes, it has good flow characteristics and can be extruded or injection-molded without forced feeding. In mixing silos (e.g. after film washing systems) densified material gives higher amounts of material in a mixing batch, thus producing a more equal mixture, compared to material not densified. Compared to standard batch type agglomerators the HV densifier is a continuous process without adding water to the material. The flakes are being granulated and automatically fed into the agglomerator via a buffer silo. The densified material is being reground in a second granulator; an air classifier sorts out dust and fine particles and returns them again into the densification process for further agglomeration. The agglomerator itself consists of two discs equipped with kneater pads. One of the discs is rotating with high speed; a drive power between 22 kW and 160 kW (30 HP to 220 HP) on the rotating disc generates the friction needed for the densification process.

Ancillary equipment for granulators, pulverizers and fine grinders

All components of our size reduction systems are also available as individual elements for the modification of your existing lines to replace broken elements, to increase throughput, to improve the automatic operation and to increase efficiency. The following essential components are available: Big bag discharge units: They take the load of a big bag, e.g. in front of a pulverizer, and automatically transport it into a buffer or silo. They allow for a semi-automatic operation of a pulverizer line or semi-automatic discharge of the feedstock from big bags into a silo in front of the pulverizer line. Belt conveyors: Widths from 200 to 2000 mm (8 to 78 inches), lengths from 1000 to 25000 mm (39 to 975 inches). Models for light, medium and heavy loads. Vibrating conveyors: As feeders for pulverizers and discharge conveyors for hammermills; widths from 200 to 1500 mm (8 to 58 inches), lengths from 300 to 6000 mm (12 to 230 inches). Scales: To measure the throughput of your size reduction line, to transfer the measured data into your process control system. Metal detectors: Built into belt conveyors to protect the succeeding granulator from metallic parts. The detection coil will automatically stop the conveyor as soon as metal enters its detection zone. Blowers, pipes, cyclones and all ancillaries for pneumatic conveying systems: Our blowers are available from 1.5 kW to 30 kW (2 HP to 40 HP); we use pipe diameters of 60 mm to 300 mm (2.5 to 12 inches); for each blower the matching cyclone separator is available. Our own manufacturing of essential components keeps costs down for reasonable pricing. Metal separators: To protect the succeeding injection molding or extrusion systems that use the regrind material. Metal particles will automatically get separated. Big bag filling stations: For semi-automatic packaging operations we provide double big bag filling stations to ensure a continuous grinding process that will not be interrupted by big bag changes.

Granulators - SML Series

The SML models are machines for normal, everyday use in the plastics industry, besides the press or extruder as the central granulator for larger parts, as edge trim cutters and for many more application possibilities. Granulators of the SML series are available with rotor diameters from 220 to 800 mm (8 to 30 inches), a working width of 300 to 1450 mm (12 to 56 inches) and drive motors from 5.5 kW to 160 kW (7.5 to 210 HP). The C-types of the SML series are available with a space-saving fully integrated sound enclosure.

Herbold HOG-Shredder - Series HGM

The New Series: Low Speed HOG-Shredders HERBOLD Meckesheim GmbH has developed a new series of low-speed HOG-shredders, expanding their product range: HGM series, available in two sizes - HGM 60/100 and HGM 60/145 Advantages of the HGM series Insensitive to foreign bodies due to an integrated shear pin coupling Smooth running due to the massive full-steel rotor and the V-belt drive Longer knife life Most inexpensive knife design Armour-plated housing Excellent access to the rotor and the cutting knives due to a horizontally divided housing Low-speed operation, less fines, dust and noise HOG-shredders of the HGM series have been developed for the reduction of difficult, especially tough material or material containing tramp material.

Pulverizers and fine grinders

Our fine grinders model SMF and our disc pulverizers model PU have been designed for the pulverization of plastic granules, regrind, soft and semi-rigid materials. The final particle size to be obtained ranges between 0-1000 microns and 0-200 microns, depending on the type and configuration of the machines. Our focus and special knowledge centers on the pulverization of soft and rigid PVC, of PE for coating, rotomolding and the textile industry, of cellulose and the production of metal powders, e.g. calcium. The fine grinders model SMF are preferably used for soft, fibrous, thin-walled and/or elastic materials, e.g. PE drilling and milling shavings or cellulose sheets. The disc pulverizer model PU is used for grainy or brittle materials, e.g. PE-granules or rigid PVC regrind. We provide systems with and without screening machines, tandem systems with a pre-pulverizer for the raw material and a separate re-pulverizer for the oversize material returned from the screener.
