Abstract

High-Density Polyethylene (HDPE) plastic is one of the most widely used types of plastic, commonly found in products such as bottles, containers, and pipes. However, if not managed properly, HDPE plastic waste poses a significant environmental challenge. An HDPE plastic crusher machine is a tool designed to shred HDPE plastic waste into fine powder, facilitating recycling and its use in composite materials. The objective of this research is to design and construct an efficient and effective HDPE plastic crusher machine. The HDPE plastic crusher machine features a rotary knife and a robust steel frame. The rotary blade is crafted from a hard, sharp material, while the steel frame provides support for the machine's body and drive motor. The machine is powered by a 3 HP electric motor operating at a speed of 1400 RPM. Power transmission is achieved through a belt and pulley system. The machine functions by transferring power from the main 3 HP electric motor to the shaft of the crusher knife. Direct testing of the HDPE plastic crusher machine was conducted using shredded HDPE plastic. The testing process was divided into two types: one without HDPE plastic and one with HDPE plastic. The results indicated that the machine produced 100 grams of fine powder in 30 minutes. The belt and pulley transmission system demonstrated a maximum tension of 216.5 N and a working tension of 176.4 N.

Abstract

The amount of plastic waste continues to rise alongside the increasing use of plastic packaging products. To mitigate the plastic problem in Indonesia, one approach is to recycle HDPE plastic waste into powder that can be utilized for composite materials. The initial step in producing powder from HDPE plastic waste involves shredding the HDPE plastic into small flakes. These plastic flakes are then ground into fine powder. The HDPE plastic crusher machine is powered by a 3 HP electric motor and operates at a rotational speed of 1400 rpm. The design of the blades on this machine features sharp and wide edges, with a total of eight blades. Additionally, the machine body is designed with a wider shape to optimize the plastic crushing process. The transmission system used to transfer rotation consists of a pulley, V-belt, and shaft. Proper planning of the shaft is essential to determine the appropriate diameter for the HDPE plastic crusher machine. Based on the planning results, the shaft diameter selected is 25 mm, with a minimum required diameter of 16.24 mm. The final rotational speed of the crusher blade shaft is 2800 rpm, with a torque of 13,410 N·mm applied to the shaft.
