In modern industrial production, the recycling and reuse of plastics has become a crucial link in resource circulation. Plastic squeezer, as key pretreatment equipment, are widely used in plastic recycling processes. Their main function is to dehydrate and dry the crushed and washed film, providing dry raw materials for subsequent pelletizing, extrusion, and blow molding. This equipment can be used independently or in conjunction with a plastic film recycling and washing line.
01. Main Advantages
- High Squeezing Capacity: Utilizing screw squeeze technology, drying efficiency can reach over 95%, especially suitable for soft film materials.
- Increased Production Efficiency: The JGM series squeezer uses screw and electric heating, achieving a processing capacity of 200-1000 kg/h.
- Efficient Energy Saving: Compared to the traditional centrifugal dehydrators, mechanical squeezer significantly reduces energy costs.
- Automated Production: The equipment supports continuous operation, has a high degree of automation, reduces labor costs, and improves production efficiency.
- Environmental Protection: The squeezing process is environmentally friendly and pollution-free, improving the production environment.
- Modular Design: One squeezer can perform dehydration drying, hot air drying, and pelletizing, resulting in higher production efficiency.
02. Main Shortcomings
- High Initial Cost: The complex equipment structure, using wear-resistant materials and an intelligent control system, leads to higher costs than some traditional dewatering equipment.
- Limited Raw Material Types: The dewatering effect on high-viscosity or special-component plastics may be limited, it can only process certain specific types of plastics.
03. Working Principle
This equipment is mainly used in the plastic recycling industry and is suitable for processing various types of plastic films, such as LDPE film, agricultural film, and PP woven bags. The crushed and washed material enters the barrel and screw, where the screw applies high-intensity squeeze pressure. After extrusion, the material is pushed into the die surface cutter, ultimately cut into semi-plasticized granules.
Machine Screen System
04. Structural Features
Its main components include the barrel, screw shaft, drive unit, die cutter, and screen system.
- The barrel is typically made of stainless steel to resist corrosion and wear.
- The screw shaft is precision-machined to ensure smooth rotation and high squeezing efficiency.
- The drive unit usually employs a combination of a motor and a reducer to provide stable torque.
- The screen section allows for the replacement of screens with different sizes to suit various plastic types, depending on the particle size and dewatering requirements.
- A specially designed high-torque gearbox and a self-developed bearing seat provide powerful screw thrust, resulting in superior drying performance.

05. Maintenance Points
Regular maintenance is crucial for the long-term stable operation of the plastic squeezer. Maintenance includes cleaning residues inside the barrel, inspecting the screw shaft for wear, lubricating drive components, and replacing damaged screens. It is recommended to stop the machine for inspection after a period of operation to prevent excessive wear leading to malfunctions. Operators should receive basic training and be familiar with the correct operating procedures to avoid overloading the equipment or handling unsuitable materials.
