Product Introduction
The disc screen is a roller-type disc dynamic screening device specifically developed for light impurity separation, screening of flexible and entanglement-prone materials, and fine material classification. It focuses on material sorting and impurity removal, accommodating materials up to 1,000 mm. Widely used in OCC (Old Corrugated Containers) waste paper sorting, household waste, aged waste, and recyclable solid waste screening scenarios, it is a specialized core screening device for solid waste sorting, recycled resource processing, and refined material classification industries.
The equipment features a horizontal parallel roller installation structure. A drive system powers multiple sets of parallel shafts to rotate synchronously, with each shaft equipped with integrated, uniquely shaped screening discs. During operation, the discs rotate in an interleaved pattern, continuously conveying, tumbling, and loosening the material. As the material is conveyed forward along the rollers, fine particles rapidly drop through the gaps between discs for separation, while oversized materials, light debris, plastic fabric strips, and impurities are conveyed along the discs to the discharge outlet.
The proprietary interleaved disc structure features a hole-free design that eliminates clogging and material sticking, adapting to high-humidity, high-adhesiveness, and entanglement-prone complex materials. It effectively resolves common industry pain points found in traditional screening equipment, such as easy material clogging, material wrapping, poor screening stratification, and incomplete impurity removal.
The equipment employs a user-friendly modular structural design. Both the discs and rollers are independently removable for convenient maintenance and replacement. The entire machine is equipped with an external dust- and odor-proof sealed enclosure and an electrical overload protection system, balancing screening precision, operational stability, and production safety. With low operating noise, anti-wrapping performance, a low failure rate, and convenient disassembly and maintenance, the simple maintenance workflow effectively reduces labor intensity and equipment operation and maintenance costs. It supports round-the-clock continuous industrial operation and delivers exceptional scenario adaptability and practical performance.
Core Advantages
The equipment uses multiple sets of interleaved wear-resistant discs, abandoning the traditional screen mesh screening model. It relies on the roller gaps for material screening, fundamentally eliminating screen mesh clogging, material adhesion, and fabric strip wrapping issues. The proprietary dynamic tumbling structure continuously breaks apart damp, caked materials and precisely separates fine materials from light impurities. Disc spacing can be customized according to customer material specifications and screening standards, accommodating various wet, sticky, and entanglement-prone mixed materials, delivering screening performance far superior to traditional screening equipment.
The roller rotation speed can be precisely adjusted, accommodating materials of varying moisture content, adhesiveness, and hardness, making it perfectly suited for differentiated operational scenarios such as OCC waste paper decontamination, solid waste sorting, and spoil screening. Combined with independent drive vibration-damping structures and integrated rubber vibration-damping components, the equipment effectively buffers operational vibrations and reduces operating noise. The entire machine exhibits minimal oscillation amplitude and a low component wear rate, running smoothly and continuously throughout, ensuring efficient and stable production line output.
The entire machine adopts a modular split structure, where individual discs and rollers can be independently disassembled and replaced without dismantling the entire machine. Maintenance can be completed using common tools. The equipment body provides ample operating access, with a simple structure free of complex components, making troubleshooting, equipment cleaning, and component replacement straightforward. This significantly reduces equipment downtime and effectively lowers labor maintenance difficulty and production operation and maintenance costs.
Equipped with a professional electrical overload protection and automatic material jam alarm shutdown system, the equipment automatically shuts down and triggers an alarm when issues such as material jamming, feed overload, or abnormal current occur, mitigating risks of motor burnout and component damage. The discs are made of high-strength, wear-resistant materials with corrosion resistance, wear resistance, and fracture resistance. The rollers deliver excellent load-bearing performance, capable of long-term operation in harsh working conditions with high dust, high humidity, and heavy debris. The entire machine features a robust and durable structure, ensuring a long equipment service life.
