Abstract:
Global plastic production has seen a significant surge owing to its versatile applications resulting in a large volume of plastic waste polluting the environment. However, the high cost and size of plastic crushers have hindered efficient plastic recycling efforts. This research focused on creating a cost-effective, portable plastic crusher tailored for local use. The machine comprises four main units: the feeding, grinding, power, and framework units. A 3D model was crafted using Solid Works software (2017 version 25), and essential components were constructed from mild steel. The feeder has a capacity of 837480 mm3, a 20 mm diameter shaft with a power rating of 2.078 kW, and an outlet volume of 748692 mm3. Performance tests using High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Poly Vinyl Chloride (PVC), and Polyethylene Terephthalate (PET) indicated throughput capacities of 2.83, 2.71, 6.00, and 1.60 kg/h, respectively. The machine has efficiencies of 73.3%, 53.85%, 60%, and 50% for HDPE, LDPE, PVC, and PET, respectively. Notably, the portable plastic grinding machine excels in grinding HDPE, making it highly recommended for small and medium-sized enterprises. This innovation focused on bolstering plastic recycling efforts in localized contexts.
