Unlike other items thrown away on a daily basis such as paper waste and food waste, plastics are not biodegradable, so landfills accumulate large amounts of plastic jugs, bottles and bags. In fact, plastics make up around 20% of the material found in solid waste recycling streams nationwide. A granulator is used to shred this material into tiny flakes called granules, making it reusable and reducing the pileup in landfills. Along with being environmentally friendly, this method is also cost-effective because not only does the company reduce their disposal costs, there is also money gained from selling the raw material to manufacturers who will reshape it into new plastic products.
The process of recycling plastic isn’t very difficult, so long as you have the right equipment. The primary piece of machinery used in plastic recycling is a granulator. This size-reduction device takes whole plastics down to a uniform blend of flakes in just a matter of minutes. Granulators are quick and easy to use, and as long as they used and maintained properly, they provide years of quality service.
As the material is fed into the granulator, it falls into the cutting chamber where rotating knives pass alongside stationary knives, shearing the plastic (think scissors). High impact plastics that cannot be sheared easily are granulated as the knives cut the plastic like an axe, shattering it. The output is chips of a random size and shape; the maximum chip size is dictated by a screen at the exit of the cutting chamber. The plastic is cut down further and further until it reaches a small enough size to fit through the screen.
This Cumberland Granulator is powered by a 100 hp, 220/460 V, 3-phase electric motor. It has a 20” x 12” infeed opening and comes equipped with an infeed hopper, stand and controls.
