In the complete waste plastic recycling and regeneration process system, raw waste plastics enter production lines in large, irregular, thick-walled and hollow forms, including home appliance casings, automotive plastic parts, plastic pipes and profiles, packaging containers, and industrial plastic scraps. Featuring large volume, inconsistent dimensions and disordered shapes, these raw materials cannot be directly processed by fine procedures such as air sorting, silicone sorting, grinding and pelletizing. Without professional crushing and volume reduction equipment, subsequent multi-stage sorting and purification, precision grinding and finished product production cannot be carried out normally. Therefore, as the first core process unit of the plastic sorting, crushing and milling line, the plastic crusher undertakes the basic functions of full-line material pretreatment, dimension standardization and volume reduction, serving as the starting point of the entire production line’s closed-loop process.
Rather than operating as standalone processing equipment, the plastic crusher is fully embedded in the process chain of automated complete production lines. Installed downstream of the tipper feeding system and upstream of the air sorting machine, it receives various waste plastics conveyed by the feeding system, and converts bulky and irregular materials into uniformly sized plastic fragments through mechanical shear crushing, providing qualified feeding conditions for all downstream processes, including air impurity removal, silicone fine sorting, material buffer storage, grinding and pelletizing, and dust treatment. Its structural design, mechanical strength, electrical configuration, safety protection and energy consumption standards are strictly formulated in accordance with universal international industrial specifications. Adaptable to continuous production, environmental compliance and safety production requirements of recycling factories worldwide, it serves as the standard foundational equipment for international standardized plastic recycling production lines.
The plastic sorting, crushing and milling line adopts a progressive process logic of step-by-step processing and purification: the tipper feeding system realizes automatic feeding, the plastic crusher completes material volume reduction and dimension shaping, the air sorting machine removes light impurities, the silicone sorting equipment eliminates elastic colloidal impurities, the buffer hopper balances production rhythm, the grinding system manufactures finished pellets, and the baghouse dust collector achieves eco-friendly dust removal. The operating parameters, feeding standards and load limits of all downstream equipment are established based on the discharging specifications of the plastic crusher.
Connected upstream to the automatic tipper feeding system, the crusher receives continuous and uniform bulk waste plastic materials conveyed from the feeding device, replacing manual feeding and realizing full-line automatic feeding. It uniformly crushes mixed waste plastics with varying thicknesses, sizes and materials, solving the problem of disordered raw materials that cannot be processed via batch sorting.
It is directly matched with the air sorting machine downstream. The dimensional uniformity of crushed materials directly determines the air sorting accuracy and impurity removal efficiency. Uniform particle size ensures stable airflow sorting and efficient separation of paper scraps, floating dust, film and other light impurities. Inconsistent fragment sizes and mixed thick and thin materials will cause airflow disorder, residual impurities and reduced sorting efficiency. Meanwhile, uniform crushed materials are a prerequisite for high-precision operation of silicone sorting equipment, effectively preventing roller jamming, unstable material bouncing and declined sorting accuracy.
From the perspective of overall process structure, the plastic crusher acts as the “material shaping source” of the entire production line. Crushing quality determines full-line sorting quality, and crushing stability governs the overall operational stability. As the first process checkpoint for standardized material shaping, the crusher lays a solid foundation for subsequent sorting, purification and pelletizing procedures, enabling automated, standardized, large-scale and international production of plastic recycling lines.
Adopting heavy-duty industrial structural design, the plastic crusher features a thick steel plate welded fuselage with high rigidity, strong impact resistance and outstanding wear resistance, capable of withstanding long-term shear processing of various hard and thick-walled industrial plastics and adapting to 24/7 non-stop mass production in overseas factories. The equipment consists of a feeding box, crushing chamber, main spindle rotor, alloy moving blades, fixed bottom blades, screen mesh filtering structure, drive motor, belt transmission system, overload protection system and electric control operating system. With a mature and stable structure, highly standardized wearing parts and low maintenance difficulty, it meets international industrial design standards for low failure rate and low operating cost.
The equipment adopts pure mechanical shear crushing principles, different from impact pulverization methods. After entering the sealed crushing chamber, waste plastics are continuously sheared, torn and cut by high-speed rotating moving blades cooperating with fixed bottom blades, turning bulky plastics into fine uniform fragments. A customized screen mesh at the bottom of the chamber screens qualified materials for discharge, while unqualified bulky materials remain inside for secondary circulating crushing until meeting dimensional standards. Replacing screen meshes with different apertures can precisely adjust discharging particle sizes to match feeding requirements of different downstream processing equipment.
The integrated fully sealed crushing chamber prevents material splashing, reduces raw material loss and restrains dust diffusion during operation. Equipped with feeding buffering and anti-rebound structures, it solves slipping and feeding difficulties of thin and hollow plastic materials, greatly improving feeding stability and crushing efficiency. The belt buffer transmission system eases startup impact and instantaneous load, protecting the main spindle and motor to extend overall equipment service life.
The electric control system is equipped with multiple safety mechanisms, including overload protection, blockage reverse rotation protection, no-load standby and emergency stop self-locking. When encountering uncrushable foreign matter, material accumulation or overload operation, the system automatically stops and reverses to discharge blocked materials, avoiding motor burnout and blade damage. The equipment supports linkage with the full-line PLC control system, realizing synchronous start-stop and rhythm coordination with feeders and air sorters to ensure continuous automated production.
It uniformly crushes diverse raw materials including home appliance casings, automotive plastic parts, pipes, plates, packaging plastics and industrial scraps into standardized plastic fragments. It eliminates production obstacles caused by irregular raw material sizes and uneven thicknesses, unifies full-line feeding standards, stabilizes operating parameters of all downstream sorting equipment, and guarantees consistent processing quality of the entire production line.
Equipped with high-toughness and high-hardness alloy blades, the crusher is compatible with soft plastics, hard plastics and thick-walled engineering plastics. It stably processes thin packaging plastics as well as thick home appliance and automotive structural plastics. Featuring strong material universality, it adapts to diversified waste plastic recycling working conditions across global markets.
The fully sealed crushing structure controls dust diffusion at the source. Reserved standard dust removal interfaces can be seamlessly connected with baghouse dust removal systems to collect fine operational dust. Workshop dust concentration and noise indicators meet environmental access standards of industrial parks in Europe, America, Southeast Asia, the Middle East and other regions, supporting environmental assessment approval and clean production requirements of overseas factories.
Optimized chamber structure and blade layout, combined with automatic reverse discharging function, effectively solves common industrial problems such as spindle winding, material accumulation and equipment jamming caused by the high toughness of plastic materials. With ultra-low failure rate and excellent continuous operation capability, it perfectly adapts to the low-labor and unattended automated production mode of overseas factories.
The crusher’s electric control system integrates with the centralized production line control system. It automatically adjusts feeding speed and crushing power according to the operating load of downstream air sorting and fine sorting equipment, balancing full-line production rhythm, preventing material accumulation and blockage, and improving overall production capacity and finished product qualification rate.
