Friction machine

Product Name: High speed Friction Cleaning Machine (also known as Strong Friction Cleaning Machine)

Product positioning: The core equipment of the "hot washing" or "friction cleaning" section in the crushing and cleaning line, responsible for thoroughly removing stubborn stains, grease, sediment, label residue and other impurities attached to the surface of plastic sheets through high-strength mechanical friction and hot water/cleaning agent chemical action. It is a key purification unit to improve the quality and value of recycled plastics.

1、 Core functions and working principles

Core functions:

Strong peeling: Using high-speed friction, collision, and scrubbing between materials and equipment, as well as between materials, to physically peel off surface pollutants.

Pre impurity removal: Separate loosely attached impurities (such as residual sand and paper scraps) from plastic sheets.

Heating and chemical cleaning assistance: usually combined with hot water and cleaning agents to soften pollutants, reduce their adhesion, and achieve "physical+chemical" collaborative cleaning.

Material conveying and lifting: The built-in rotating mechanism of the equipment forcibly transports materials from the feeding end to the discharging end while cleaning, achieving continuous production.

Working Principle:

The broken plastic sheets, along with hot water and cleaning agent, enter the water filled cleaning tank through the feeding port. The high-speed rotating spindle in the groove drives the friction blades to generate strong turbulence. Plastic sheets collide with each other, rub against groove walls and blades in turbulent flow, and dirt is peeled off and dissolved or suspended in water. The clean material after cleaning is lifted by the rotating mechanism and discharged into the next process through the discharge port, while the sewage containing impurities is discharged from the bottom or overflow port and enters the water treatment system.

2、 Main structural components

Durable groove body: Made by bending 6mm thick wear-resistant plate, corrosion-resistant and wear-resistant. The tank design includes an inlet, a drainage/discharge outlet, and an overflow outlet.

Core rotation system:

Main shaft: heavy-duty solid shaft, made of wear-resistant and corrosion-resistant materials, verified by dynamic balance in the factory.

Friction blades: core working components. The blade and spiral designs made of wear-resistant alloy steel are arranged at specific angles to achieve stirring, friction, and conveying functions.

Power and transmission system:

Main motor: High power motor (from 28kW to over 30kW), providing powerful mixing power.

Incoming and outgoing equipment:

Feed inlet: connected to upstream equipment such as elevators or conveyor belts.

Discharge outlet: The tank is equipped with a water filter screen for preliminary solid-liquid separation during discharge.

3、 Core features and advantages of the product

Efficient and powerful cleaning: The mechanical force generated by high-speed rotation is one of the most effective means of removing oil stains, label glue, and stubborn stains, and the cleaning effect is significantly better than simple soaking.

Continuous automation operation: integrating cleaning, conveying, and lifting, seamlessly connecting with front and rear equipment, achieving continuous production on the assembly line with high efficiency.

Durable and sturdy structure: Key components are designed for high wear and corrosion conditions, with a long service life.

4、 Key application scenarios

Typical applicable materials: PET bottle flakes, HDPE/PP hard plastic flakes, agricultural film/plastic film fragments, household appliance shell crushing materials, etc. after rough crushing, especially adept at handling materials with heavy oil stains, adhesive substances (labels), and high sediment.

Typical positions in the production line:

Pre crushing material → High speed friction machine → Clear water rinsing tank → Dehydrator → Drying system

Operation and maintenance:

Startup sequence: Usually, water is injected first, then the spindle is started, and finally the material is fed.

Regular inspection: Check the wear of the blades and replace them in a timely manner.

Maintain water level: Ensure stable operating water level to achieve optimal friction and conveying effects.

Daily sewage discharge: After shutdown, thoroughly discharge the sewage and clean the sediment at the bottom.
