waste plastic PP PE film recycle granulating pelletizing melt pump and screen changer

Here is the translated text about the melt pump and screen changer in the recycling and pelletizing process of waste PP and PE plastic films:

Melt Pump

Role and Importance:

In the recycling and pelletizing process of waste plastic, the melt pump is one of the critical pieces of equipment on the plastic pelletizing production line. It significantly enhances production efficiency, reduces material residue, and improves product quality. As the importance of waste plastic recycling grows, the demand for melt pumps is also increasing, especially in high-temperature, high-pressure, and high-viscosity operating conditions, where the role of the melt pump becomes even more pronounced.

Features and Advantages:

High Temperature and Pressure Resistance: The Haike H-series high-temperature melt pump can withstand operating conditions of high temperature (up to 510°C) and high pressure (up to 70MPa), meeting the demands of waste plastic recycling and pelletizing.

Optimized Design: The optimized inlet and outlet design minimizes dead zones within the flow path, reducing material residue and enhancing product quality.

High Pressure Capability: Improved gear parameter design allows it to withstand ultra-high pressures and larger pressure differentials, ensuring stable production.

Long Lifespan: Constructed with special materials, it has high temperature resistance and a long service life.

High-Precision Sealing: Equipped with high-precision mechanical seals, it ensures stable pump operation without leakage.

Screen Changer

Role and Importance:

The screen changer is an essential piece of equipment in the production of recycled plastics such as PE and PP. It filters out foreign particles and impurities from the plasticized material, ensuring product quality and preventing an increase in defective products and production interruptions caused by impurities. During waste plastic recycling, the role of the screen changer is even more crucial due to the potential presence of impurities such as paper scraps, aluminum foil, gravel, iron filings, and other contaminants in the raw materials.

Types and Features:

Dual-Column Large Filter Cartridge Screen Changer: Made from high-quality alloy steel through multiple special processing steps, it features a dual-filter, dual-channel design. The filter screen is wound to increase the filtration area. Screens are replaced alternately during operation, ensuring continuous production. Equipped with a pressure stabilization structure, it operates without stopping the machine, interrupting material flow, or halting production, satisfying the high-capacity, high-quality production requirements of customers.

Fully Automatic Screen Changer: Such as the mesh belt-type fully automatic screen changer, it uses a mesh belt filter screen that automatically advances based on material pressure, eliminating the need for manual screen changes. The screen changing process is smooth and stable, with minimal material pressure fluctuations, making it suitable for various pelletizing production processes.

Other Types: Such as single-plate dual-station screen changers and double-plate dual-station screen changers, which are also suitable for different production needs.

Configuration Options:

For high-corrosion operating conditions, options for high-corrosion-resistant materials are available.

An automatic control system integrated with a PLC control system can be selected for easy operation.

A complete solution can be provided, integrating the connection and control of components such as the melt gear pump, mixer, start-up valve, underwater pelletizing die head, and others.
