Hard Plastic Crusher: Core Equipment for Efficient Hard Plastic Waste Processing
In the plastic recycling and processing industry, the hard plastic crusher is a key piece of equipment for realizing the resource utilization of hard plastic waste. It is widely applicable to high-hardness plastic materials such as polyethylene, polypropylene, nylon, and ABS, and can crush large pieces of hard plastic waste such as plastic pallets, pipe fittings, and waste appliance casings into uniform particles, providing high-quality raw materials for subsequent granulation and recycling.


The core structure of the equipment consists of a feeding system, a crushing system, a screening system, and a discharge system. The feed inlet features a widened design, coupled with a guide plate to prevent hard plastic raw materials from jamming. The crushing system's cutter shaft is made of high-strength alloy steel, and the blades are hardened to a hardness of HRC58-62, easily cutting through the internal fibrous structure of hard plastic. The screening system controls the discharge particle size through replaceable screens, with common specifications ranging from 3mm to 20mm to meet different recycling needs. During operation, the motor drives the cutter shaft to rotate at high speed via belt drive. The shearing and impact action of the moving and fixed blades crushes the hard plastic raw materials. The crushed particles are then screened; qualified particles are discharged from the outlet, while substandard materials continue to circulate and be crushed within the crushing chamber.

Compared to ordinary plastic crushers, hard plastic crushers have three major advantages: First, high wear resistance; the cutter shaft and liners are made of wear-resistant materials, extending their service life by more than 30% compared to ordinary equipment. Second, low noise design; the crushing chamber is equipped with sound insulation cotton, controlling the operating noise below 85 decibels, meeting workshop environmental standards. Third, high efficiency and energy saving; using a variable frequency motor, the speed can be adjusted according to the material hardness, achieving a crushing capacity of 500-2000 kg/h per unit time while reducing energy consumption by 15%.

During operation, please note the following: Before starting the machine, check the blade gap and screen sealing to prevent hard impurities from entering the crushing chamber; feed the material evenly to prevent overload and motor tripping; for routine maintenance, regularly clean the residual material in the crushing chamber and lubricate the bearings every six months to ensure stable operation of the equipment. Today, hard plastic crushers have become essential equipment for plastic recycling companies and injection molding plants, contributing to the effective implementation of the "green circular economy."
