What is the SWP crusher?

The SWP crusher is a horizontal heavy-duty crushing equipment specifically designed for recycling soft materials like plastics and rubber. It operates on a shearing principle, where high-speed rotating blades interact with fixed blades to shear and tear materials apart. Its standout feature is the ability to handle long, continuous feeds of materials such as PVC pipes, door/window profiles, and plastic sheets without requiring pre-cutting .

Its key differences from other crushers are as follows:

• Working Principle: The SWP crusher utilizes a shearing action​ between rotating and fixed blades. In contrast, jaw crushers rely on compression, hammer crushers on impact, and impact crushers on collision. These conventional crushers are primarily built for hard materials like ores and rocks .

• Applicable Materials: The SWP crusher is specifically for soft, tough materials​ like plastics and rubber. Other crushers, such as jaw or cone crushers, are mainly used in mining, construction, and metallurgy for hard materials .

• Feeding Method: A major advantage of the SWP crusher is whole-piece feeding; it can directly process pipes or profiles up to 6 meters long without pre-cutting. Other crushers typically require materials to be broken into smaller pieces before feeding, limiting feed size .

• Application Fields: The SWP crusher is primarily used in environmental protection areas​ like plastic and rubber recycling. Other crushers serve sectors such as mining, construction waste processing, and metallurgy, representing different application scenarios .

• Structural Design: The SWP crusher features a horizontal structure​ with an elongated hopper for long materials and horizontally arranged blades. Other crushers often have vertical, jaw, or conical structures, reflecting different design philosophies .

• Discharge Characteristics: The SWP crusher uses a screen to control particle size, producing relatively uniform discharge​ (typically 3-10mm) suitable for subsequent reuse. Other crushers offer a wider range of output sizes, from coarse to fine crushing, but may cause wrapping or over-crushing with soft materials .

• Energy Consumption & Environmental Impact: The SWP crusher is optimized for soft materials, resulting in relatively low energy consumption. Noise is controlled below 85 dB, and dust removal devices are equipped. Crushers for hard materials consume more energy, generate more noise, and have higher environmental control requirements .

In short, the SWP crusher is a specialized equipment for the plastic recycling industry. Its unique characteristics of "whole-piece feeding and shearing" are irreplaceable by general-purpose crushers, as they differ fundamentally in material type, working principle, and application scenarios
