Granulation and pelletization of plastics
Plastic recycling
Waste in the form of dust, chips, scraps, etc. from plastics is created during the production of windows, toys and a huge number of other products. A large part can be granulated and reused. A simple granulation line is enough to manage plastic waste. Plastic packaging, suitably ground, can also be granulated and used to produce, for example, extrudates in the form of long and flexible rods, which can be used in another industry.
Plastic waste can be granulated similarly to other raw materials. A characteristic feature of this raw material is a very low degree of stickiness, which requires the use of high-power granulators. For example, the GRB2 850.264 granulator will produce about 1.0 - 1.5 t/h of plastic granulate, and about 3 t/h of sawdust granulate.
The lower efficiency is caused by the feathery structure of the ground material, which significantly reduces the bulk density and causes low efficiency of the granulator.
The development of a production line concept for plastic granulate requires granulation tests in our laboratory. The test requires a minimum of 1 ton of raw material to obtain reliable information.
The plastics processing (granulation) line must include a grinding unit that reduces the size of the primary raw material to meet the technological requirements of granulation.
