Plastic Coarse Crusher for PP PE Plastic Waste

What is a Plastic Coarse Crusher for PP PE Plastic Waste?

A Plastic Coarse Crusher for PP PE Plastic Waste is a high-efficiency crusher used in the pre-treatment stage of a plastic recycling production line. It is mainly used for coarse crushing of large-volume, irregularly shaped polypropylene (PP) and polyethylene (PE) waste plastics. It uses a high-speed rotating blade assembly and fixed blades to shear in tandem, quickly breaking large-sized plastic waste into uniform particles, facilitating subsequent washing, dewatering, and granulation.

The Plastic Coarse Crusher for PP and PE Plastic Waste features a heavy-duty design for continuous operation. Its blade structure and screen size are configured according to different plastic properties to achieve high-efficiency crushing. Depending on the material characteristics and capacity requirements, the processing capacity typically reaches 500–5000 kg/h, with the output particle size generally controlled between 10–50 mm, adjustable by changing the screen.

What are the applications of the Plastic Coarse Crusher for PP PE Plastic Waste?

The Plastic Coarse Crusher for PP PE Plastic Waste can process various plastic wastes such as PP, PE, PET, PVC, ABS, and PC. It can process plastic products in various shapes, including blocks, rounds, and strips. Its applications cover a wide range of products, including plastic pipes, injection molded parts, blow molded parts, appliance casings, automotive bumpers, thick-walled rubber plastic products, woven bags, films, bottles, and beverage bottles. It can crush large, intact pieces of plastic waste into uniformly sized particles.

What are the advantages of the Plastic Coarse Crusher for PP PE Plastic Waste?

The Plastic Coarse Crusher for PP PE Plastic Waste features a large-size feed design, suitable for films, drums, and irregularly shaped plastics. The blades are made of imported special tool steel, with optional materials including 9CrSi, SKD-11, D2, DC53, and Cr12MoV alloy tool steels. The blade hardness reaches HRC60-63, offering excellent wear resistance and impact resistance. The blades can be repeatedly disassembled and sharpened after dulling, ensuring a long service life. The spindle uses a high-strength welded steel structure with a unique V-shaped design. All spindles undergo rigorous dynamic and static balancing tests to ensure operational reliability. The spindle design can be customized to meet different material requirements, and the final output particle size can be controlled between 10mm and 50mm by adjusting the screen.

How Does the Plastic Coarse Crusher for PP PE Plastic Waste Work?

During operation, waste plastic is fed into the inlet manually or via a conveyor. Under the shearing force created by the high-speed rotating blade assembly and the fixed blade, the plastic is rapidly crushed. The crushed material is filtered through a screen; materials that do not meet size requirements are further recycled and crushed. Once the target particle size is reached, the material is automatically discharged for washing or granulation. The entire process is continuous and stable, meeting the needs of large-scale plastic recycling.

Plastic Coarse Crusher for PP PE Plastic Waste Case

A plastic recycling company in the Middle East needed to pre-process and crush recycled plastic buckets, sheets, and injection molding scraps when building a PP and PE waste plastic washing and granulation production line. Considering both capacity and material size requirements, they ultimately selected a Plastic Coarse Crusher for PP PE Plastic Waste for coarse crushing of rigid PP and PE waste plastics. The feed particle size is ≤800mm, and the output particle size after crushing is controlled at 20-30mm, with a processing capacity of 3000kg/h, which can be directly fed into the subsequent washing system. The machine is equipped with a heavy-duty frame, SKD11 wear-resistant blades, a 30mm replaceable screen, a 75kW motor, and an automatic conveyor belt feeding system, achieving continuous and stable operation, effectively reducing labor costs, and improving the efficiency of subsequent washing and granulation.

Plastic Coarse Crusher for PP PE Plastic Waste FAQ

Q: Can the Plastic Coarse Crusher for PP PE Plastic Waste directly wash materials? 

A: The main function of the Plastic Coarse Crusher for PP/PE Plastic Waste is dry sizing. When crushing PE film with high clay content, a drainage screen can be installed at the bottom to remove some of the clay and sand. For thorough cleaning, a dedicated friction washer must be connected afterward.

Q: What if the output flakes are not uniform in size?

A: The flake size is determined by the screen mesh size. As long as the blade and screen gap are adjusted correctly, more than 85% of the flakes will be within the target range. It is recommended to check the blade wear regularly; uniform wear indicates good flake consistency.

Q: Does the electrical system support remote monitoring?

A: Standard configuration includes a conventional electrical cabinet with start/stop protection. We can upgrade to an intelligent control box with a PLC and communication interface upon customer request, supporting real-time monitoring of current and temperature, and can be integrated into the factory management system.
