The single screw volumetric dosage units DVG are ideal to dose material in form of granule, free flowing ground material. They are usually employed to dose masterbatch, virgin material and regrind.
They are available in several configurations to achieve outputs from 0,3 to 5000 kg/h.
They have been designed to provide precise and reliable dosage. The predisposition to a quick disassembly allows easy and fast cleaning.
Indicated outputs are based on tests with material in granule having BD 0,60 kg/dmc
Application
DVG dosage units are usually placed directly under the hopper of the extruder. Depending on the requirements, the individual dosage units can be installed in groups of 2 or 3.
Main sectors of use:
– extrusion
– injection moulding
– blow moulding
– recycling
Operation
The volumetric dosage units are devices for the dosage provided by means of a screw. The dosage units used singularly operate with a speed variation and their output is determined by the rotation speed of the dosage screw.
Advantages
– no need to create blends beside the machine
– faster production changes
