stretch film recycle plastic granulator melt pump

The melt pump for the stretch film recycling plastic granulating machine plays a pivotal role in the plastic recycling and granulation process. Below is a detailed introduction to this equipment:

I. Definition and Function

The melt pump for the stretch film recycling plastic granulating machine is a specialized device designed for the conveyance, pressurization, and metering of high-temperature, high-viscosity polymer melts. It is primarily employed in the recycling process of plastic waste such as stretch films, converting the recovered plastics into reusable granules through the granulating machine. The stability and efficiency of the melt pump are crucial in ensuring the quality of the granulated product.

II. Key Features

Stable Flow Rate: The melt pump adopts a unique volumetric design that effectively isolates the pressure and flow fluctuations in the feed zone from affecting the discharge zone, achieving stable flow delivery. This is significant for controlling the melt flow rate during granulation and enhancing product consistency.

High Pressure Capability: The melt pump generates high pressure, enabling the transportation of high-viscosity melts to required locations. In the stretch film recycling and granulation process, this high pressure facilitates better penetration of the melt through filters, reducing clogging issues.

Precise Control: By adjusting the pump's rotational speed, the melt pump achieves precise flow control. This is vital for meeting various process requirements and optimizing production parameters.

High Efficiency: The melt pump can produce high flow rates at low rotational speeds, thereby enhancing energy efficiency and production output. This contributes to lower production costs and improved economic benefits.

III. Parameters and Specifications

The melt pump's parameters encompass various aspects, including model specifications, conveying capacity, pressure range, temperature range, and viscosity range. The specific parameter selection depends on the actual needs and process conditions of the stretch film recycling plastic granulating machine. For instance, model specifications are typically expressed in terms of displacement per revolution, measured in cubic centimeters (cc), ranging from 0.1cc to tens of thousands of cc; conveying capacity is directly related to the model specifications, with output flow further adjustable by altering the rotational speed; the pressure range can reach 0-40MPa or even higher; and the temperature range covers the processing temperatures of most plastics.

IV. Applications and Advantages

The melt pump for the stretch film recycling plastic granulating machine is widely used in the plastic recycling and reuse industry. It not only enhances the processing efficiency and quality of recycled plastics but also reduces production costs and energy consumption. Furthermore, the pump's stability and reliability help minimize downtime due to malfunctions, thereby improving the overall operational efficiency of the production line.

V. Maintenance and Servicing

Regular maintenance and servicing are necessary to ensure the normal operation and extended service life of the melt pump. This includes checking the pump outlet pressure, tightening bolts, monitoring bearing temperature, inspecting shaft seals, and checking the power supply. Additionally, maintaining the pump's cleanliness and lubrication while preventing foreign objects from entering the pump body to avoid damage is crucial.

In conclusion, the melt pump for the stretch film recycling plastic granulating machine is a crucial piece of equipment in the plastic recycling and reuse sector. With its features of stable flow, high pressure capability, precise control, and high efficiency, it plays a vital role in the production process.
