Kitech Machinery Customized 500-800 kg/h PE/PP Rigid Plastic Washing Line

Kitech Machinery proudly presents a high-performance, automated plastic washing line custom-engineered for our client in Saudi Arabia. This system is specifically designed for the efficient recycling of HDPE/PP rigid plastic containers (gasoline bottles, daily-use containers, shampoo bottles). Achieving an output of 500-800 kg/h, it meets the demands of large-scale, continuous operation, significantly enhancing the recovery value and reuse rate of post-consumer rigid plastics.

I. Main Process Flow

Belt Conveyor → Crusher → Screw Loader → Low‑Speed ​​Friction Washer → Separation Tank → Screw Loader → Centrifugal Dryer → Pipe line Heater → Packing Silo

II. Main Core Components

✅ A belt conveyor equipped with a sensitive metal detector to remove metal impurities.

✅ A heavy‑duty crusher with alloy blades crushing plastic containers into uniform flakes.

✅ Enclosed screw conveyors ensure smooth plastic material transfer between stages.

✅ The low‑speed friction washer gently removes most surface dirt, labels, and sand.

✅ The separation washing tank further purifies flakes through deep cleaning

✅ A centrifugal dryer efficiently removes surface moisture, reducing energy consumption in the following pipe line dryer.

✅ Pipe line dryer where controlled hot air circulation brings moisture content below 3%.

✅ Finally, clean, dry flakes are stored in a sealed, moisture‑proof silo, ready for reuse.

01 Belt Conveyor

Equipped with a wear-resistant rubber belt, it ensures smooth and constant feeding of raw materials into the crushing stage. An integrated high-sensitivity metal detector effectively identifies and alerts operators to remove metallic contaminants, protecting downstream equipment and ensuring operational safety.

02 Crusher Machine

Optimized for plastic films, small hollow containers, and bottles, our crusher produces uniform flakes ideal for subsequent washing and drying. It features high-quality bearings and counterweight wheels, a low-consumption WEG motor, an automated electric hydraulic control system, high-hardness D2 alloy blades, a programmable PLC control system, and customizable screen sizes.

03 Screw Conveyor

As a versatile Screw Conveyor, it utilizes a rotating spiral driven by a motor to transfer materials. Its enclosed structure seamlessly connects key process stages, ensuring steady transport of crushed flakes, preventing spillage and secondary contamination, thereby guaranteeing coherent production flow. It is renowned for its simple structure, small footprint, easy operation, and low maintenance cost.

04 Friction Washer

This Friction Washer employs a slowly rotating drum to create gentle yet continuous physical friction among the flakes. This method effectively removes most surface contaminants, sediment, and label residues without relying on high-speed water impact or harsh chemicals. It minimizes material breakage and powder generation, ensuring cleaning efficacy while preserving flake quality. Serving as a pre-wash stage, it significantly reduces the burden on subsequent steps and conserves water.

05 Floating Washing Tank

This Floating Washing Tank is a crucial component for deep cleaning and impurity separation in plastic recycling. Constructed from premium corrosion-resistant materials, it withstands potential chemical wear during the process, ensuring long service life and reduced upkeep. Kitech offers various sizes to accommodate different production scales, effectively separating and rinsing flakes for higher purity.

06 Centrifugal Dryer

Utilizing high-speed centrifugal force, this Centrifugal Dryer rapidly removes the bulk of surface moisture from plastic flakes. It delivers excellent dewatering performance for rigid plastics like PP, PE, HDPE, and PET, substantially lowering the energy load for the subsequent thermal drying phase.

07 Pipe Line Dryer

The Pipe Line Dryer ensures thorough convective drying of flakes through a controlled hot air circulation system. It meticulously reduces the material's moisture content to below 3%, a critical step to ensure the recycled plastic meets the moisture standards required for downstream reprocessing such as blow molding or injection molding.

08 Packing Silo

Finally, the dried and clean flakes are conveyed into a sealed packing silo for temporary storage. Designed to be moisture-proof and dust-proof, it prevents material reabsorption of humidity or contamination, guaranteeing stable quality for either packaging or direct feeding into reproduction lines.
