Large-Scale Recycling Plant Mass Production Case: 1000-type Crushing and Washing Line for High-Pollution Film & Woven Bag Water Washing Production
With the standardized and large-scale upgrading of the plastic recycling industry, small and medium-sized simple washing equipment can no longer meet the mass production and quality improvement needs of high-pollution mixed materials. Many recycling factories can only process clean and light mixed materials due to insufficient equipment decontamination capacity, incomplete sorting and limited output. High-oil and muddy waste films and woven bags cannot be efficiently utilized, resulting in serious material waste and narrow profit margins. A large professional plastic recycling enterprise in Hebei mainly engages in the recycling and deep processing of industrial and agricultural waste PE films and PP woven bags, processing large quantities of long-term open-air stacked and heavily polluted waste plastics all year round with thick oil stains, excessive sediment and mixed impurities. The original small and medium-sized single-stage crushing and washing line has insufficient output, incomplete cleaning, mixed light and heavy materials and poor dewatering effect, resulting in uneven finished product quality, inability to meet high-end deep processing orders and dual limitations in production capacity and quality. After on-site testing, parameter comparison and cost accounting of multiple models, the customer finally fully commissioned our 1000-type crushing and washing line to achieve comprehensive production line upgrading.
Before renovation, the customer’s original equipment had many mass production pain points: the thin-walled crushing host with insufficient power caused uneven crushing of large bundled materials, requiring manual pre-cutting and increasing labor costs; single-stage friction washing had weak decontamination force, failing to completely remove stubborn oil stains and aging dirt, resulting in black flakes and high impurity content; the short rinsing tank had poor sorting accuracy, allowing heavy impurities such as sand and metal to mix into finished products and reduce material purity; poor dewatering and air-drying effects led to damp and adhesive materials, causing frequent bubbles and defects in subsequent pelletizing, low yield rate and insufficient production capacity for large-scale factory production. To break through the capacity and quality bottlenecks, the customer specially selected the high-configured fully automatic 1000-type crushing and washing line to replace old equipment.
After the official commissioning of the equipment, all mass production pain points are fully solved. The 25mm thick steel plate 75KW heavy-duty crusher delivers strong and stable crushing power, directly crushing bundled and large waste plastics without manual pre-cutting, achieving uniform flake size and greatly improving front-end pretreatment efficiency. The linked operation of dual 22KW high-speed friction units performs high-intensity kneading to strip stubborn oil stains, deep sediment and aging colloid on material surfaces, completely solving the previous problems of residual stains and black flakes and significantly upgrading material cleanliness.
The 8-meter extended sink-float rinsing tank exerts precise sorting advantages. The sufficient water washing space realizes thorough stratification of light and heavy materials. The 3KW shifting teeth push materials uniformly to avoid accumulation. Dual 325-type independent spirals respectively discharge sinking impurities and convey clean floating materials, completely preventing impurities from mixing into finished products and significantly improving material purity. The rear 4KW lifting machine automatically feeds materials, the 22KW horizontal dryer performs deep dewatering, and the 7.5KW air separator removes impurities via wind sorting, achieving layer-by-layer purification and drying. The final plastic flakes are dry, clean, oil-free, sediment-free, free of light debris, with uniform appearance and stable quality.
The full-line national standard star-delta electric control system features convenient operation and stable equipment operation with smooth starting, lower energy consumption and low failure rate, supporting 24-hour full-load continuous mass production. High automation greatly reduces manual intervention and significantly cuts operation and maintenance costs. The customer’s production supervisor feedback: after upgrading the crushing and washing line, the utilization rate of factory high-pollution mixed materials is greatly improved. Previously unusable dirty materials and wastes can be efficiently purified and recycled, and the finished product quality fully meets high-end pelletizing and deep processing standards with obvious product premium. The production capacity is doubled, material loss is sharply reduced, the equipment pays off in a short term, and the overall production efficiency achieves leapfrog improvement.
This case fully verifies that the 1000-type crushing and washing line perfectly adapts to the large-scale purification production of high-pollution mixed plastics in large and medium-sized recycling factories with the core advantages of heavy-duty high output, deep decontamination, precise sorting and full-automatic stable production, serving as a benchmark model for the upgrading and replacement of plastic washing production lines.
