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

What is a pipe production line? A pipe production line is a manufacturing system that transforms raw materials into finished pipes, typically through extrusion. It involves a series of sequential operations, from preparing the raw materials to cutting or winding the final product.  A pipe production line is an assembly line for pipe production, which is composed of the control system, extruder, head, shaping cooling system, tractor, planetary cutting device, turnover rack, and other equipment. Our company specializes in manufacturing various plastic pipe extrusion production lines. Including PE and PP pipe production lines, PVC pipe production lines, MPP pipe production lines, PPR pipe production lines, PERT pipe production lines, PA pipe production lines, PU pipe production lines, etc. To manufacture HDPE pipe, HDPE resin is heated and squeezed through a mold in a process called extrusion. First, raw polyethylene material in the form of pellets is moved from a silo into a hopper dryer in order to remove any moisture. The raw material is then pulled out by a vacuum pump and moved into a device called the blender. Inside the blender, a barrel heater heats the raw material until it becomes molten (at about 356 degrees Fahrenheit), which makes the material soft enough to feed through a mold. The mold, called a die, shapes the molten material into its final cylindrical form. HDPE pipes are made of food-grade polyethylene virgin material, making it safe for the transfer of potable water. These pipes are used in private and public water supply systems due to their high resistance to corrosion, wear and tear, and chemical exposure
