Toothed Roller Granulators

The granulator next to the injection moulding machine is a proven means of implementing inline recycling in plastics processing cost-effectively and efficiently. It is important to process sprues and plastic waste into high-quality regrind without thermal damage and with low noise and dust levels.

Side granulators are integrated into the workplace of the injection moulding machine in such a way that sprues and rejects are conveyed directly into the granulator hopper. In this way, the scrap does not accumulate in the first place, but is ground immediately. A suitable conveyor system then extracts the fresh regrind from the mill. In the next step, this regrind is fed back into the injection moulding process via mixing diverters or dosing devices.

Granulators for auxiliary operation are available in different sizes. The appropriate granulator size is designed according to the geometry of the parts to be ground and the required throughput in kg/h. Digicolor relies on the proven, slow-running toothed roller mills from Moditec. Each granulator can be equipped with different hoppers in order to optimise the granulator to the individual installation situation of the processing machine. Low designs can be positioned directly under the production mould so that sprues fall directly into the granulator hopper.
All grinders are designed so that the combs and counter-combs of the cutting unit can be reversed. In this way, the service life of these cutting elements is doubled. The unique design of these granulators guarantees easy maintenance and cleaning of the grinding chamber.
Goliath beside-the-machine granulators are characterised by their high performance and industrial suitability in recycling processes in plastics processing. These toothed roller granulators can always be operated economically when sprues and rejects, which previously had to be disposed of, are processed into valuable regrind.
