Ecuador-PE/PP Household Waste Plastic Flakes Shredder Washing Pelletizing System

I. Project Background & Client Pain Points

In the South American recycled plastics market, the recycling of household waste plastics has always been a challenging industry issue. Local recycling companies in Guayaquil, Ecuador, have long been deeply involved in the recycling of household waste plastics, mainly dealing in the recycling and remanufacturing of waste plastic baskets, plastic buckets, plastic chairs, drip irrigation tape, and miscellaneous PE/PP materials. Before equipping with a professional plastic recycling system, they faced common industry pain points that severely restricted capacity and profitability:

1. Complex Raw Materials with Many Impurities, Making Processing Difficult: Household waste plastics are diverse, varying in type and hardness, with surfaces covered in stains, mud, and other impurities. Furthermore, the materials vary in size and are hard, making it impossible for ordinary simple equipment to thoroughly clean and purify them. The purity of the finished particles does not meet standards, resulting in low market premiums.

2. Fragmented processes and low production efficiency: Traditional recycling equipment is mostly pieced together from individual machines, lacking standardized production lines. The processes of shredding, washing, drying, and granulation are disconnected, relying heavily on manual labor. This results in high production costs, unstable capacity, and an inability to achieve large-scale continuous production.

3. Unstable finished product quality and high loss rate: Single-stage pelletizing processes result in incomplete filtration and uneven plasticization, leading to numerous impurities and inconsistent quality in recycled particles. This makes it difficult to meet the high-quality raw material procurement standards of local and surrounding markets, causing customers to face long-term problems of raw material waste and unsold finished products.

4. Low automation and high maintenance costs: Outdated equipment lacks intelligent control systems, making precise control of production parameters impossible. Frequent malfunctions, high energy consumption, and poor long-term operational stability make it unsuitable for sustained mass production.

To address these pain points, Kitech Machinery provides customized integrated household waste plastic solutions, creating a highly adaptable, and highly stable recycling solution that completely solves the industry problems of difficult waste material processing, poor quality, and low efficiency. The complete set of equipment has been operating stably in the local area for 4 years, continuously producing high-quality PP/PE recycled particles for customers, helping them achieve stable profitability and green and compliant production.

II. Kitech Customized Plastic Recycling Line Solution

The production line delivered this time is a fully automatic plastic recycling machine integrated waste plastic recycling and granulation solution. It integrates two core modules: pretreatment cleaning and fine granulation. Equipped with a PLC intelligent computer control system, it achieves fully automated operation from waste raw material feeding, impurity removal, shredding, washing, drying, plasticizing, filtration to finished product granulation, requiring no manual intervention and significantly reducing labor costs and production errors.

1. Pretreatment Washing System: Deep Impurity Removal, Ensuring Raw Material Cleanliness

Addressing the characteristics of household waste plastics—high impurity content, large volume, and hard texture—Kitech Machinery has equipped a professional plastic recycling washing line with highly adaptable pretreatment equipment to achieve fine pretreatment of raw materials, controlling finished product quality from the source. Core configurations include: AGS series high-power shredder, AGF series high-efficiency crusher, dual rinsing tanks, continuous low-speed friction washing equipment, high-efficiency dewatering machine, hot air drying system, and pre-mounted metal detection device.

During production, waste plastic raw materials are first precisely screened by a metal detector to thoroughly remove metal impurities, preventing equipment wear and eliminating finished product defects. Then, a shredder and crusher uniformly pulverize the varying sizes of rigid waste plastic into 3×3cm standard fragments, standardizing the material specifications and laying the foundation for subsequent cleaning processes.

The standardized plastic fragments are then soaked in a rinsing tank for decontamination, followed by low-speed continuous friction washing to deeply remove stubborn stains, thoroughly removing mud and residual contaminants from the raw material surface. Finally, a high-speed dehydration and hot air drying integrated equipment completely removes moisture from the material, preventing damp materials from affecting subsequent plasticizing effects and ensuring the dried material is dry, clean, and of uniform quality.

2. Two-Stage Single-Screw Plastic Pelletizing Line: Stable Plasticization, High-Quality Particles

To address the issues of uneven plasticization, impurity residue, and poor product stability associated with traditional single-stage granulation, Kitech Machinery employs a two-stage single-screw granulation process, coupled with a refined filtration and cooling plastic pelletizing line. This significantly improves the purity and appearance of recycled particles. The core configuration includes: a KSP first-stage single-screw extruder, a KCP second-stage single-screw extruder, and a water-cooled pelletizing system.

The dried, clean plastic fragments are fed into the first-stage extruder for initial melting and plasticization, followed by primary filtration to remove large molecular impurities. The second-stage extruder then undergoes secondary refined plasticization and high-precision filtration to thoroughly remove fine residual impurities, ensuring a uniform and stable plastic melt. Finally, the pellets are water-cooled, drawn into pellets at a uniform speed, producing full-bodied, highly pure, and stable PP/PE recycled particles, fully meeting the market's high-end material requirements.

III. Core Advantages and Adaptability of the Recycling Line

Kitech Machinery's integrated recycling and pelletizing production line boasts four core advantages: high compatibility, high stability, high cost-effectiveness, and low maintenance costs. It is highly versatile, adaptable to various types of household and industrial waste plastics for recycling:

1. Wide Range of Raw Material Adaptability, Solving the Problem of Mixed Material Processing: The fully automatic plastic recycling machine can comprehensively process various types of hard plastics and mixed materials, including plastic baskets, plastic buckets, plastic boxes, waste drip irrigation tape, plastic pipes, plastic toys, car bumpers, etc.; it is compatible with various common plastic materials such as PE, PP, PC, ABS, HDPE, and LDPE, offering multiple uses and expanding the customer's raw material recycling scope, thus increasing revenue potential.

2. Intelligent Fully Automated Production, Significantly Reducing Costs and Increasing Efficiency: The entire process is controlled by PLC intelligently controlling production parameters, ensuring smooth process transitions and a high degree of automation. This significantly reduces manual input, minimizing human error and labor costs; the continuous mass production mode effectively improves production efficiency, helping customers expand production capacity and seize market share.

3. Dual-stage precision manufacturing process for superior finished product quality: Dual remodeling and multi-stage filtration processes completely solve the problems of high impurities, poor appearance, and unstable performance in traditional regenerated particles. The finished particles have high purity, good uniformity, and strong stability, resulting in higher market acceptance and added value.

4. Precision manufacturing for durability and long-term stable operation: The core components of the equipment are precision-manufactured, wear-resistant, durable, and have a low failure rate, making them suitable for long-term, high-intensity continuous operation. The equipment's stable and trouble-free operation for four years in this project fully verifies the superior quality of Kitech equipment, helping customers reduce downtime losses and lower subsequent maintenance costs.
