China Wholesale Double Screw Plastic Granule Extruder Factories – PET flake granulation machine – Purui

The PET characteristic viscosity can be controlled very well without complicated precrystallization dryer system.

PURUI research and design new single screw with compactor especial for processing PET flakes, double cutter and special insulation layer. Adopt underwatering cutting system. The IV drops a little during the whole production process. And the IV can be improved by adding some suitable additives.

new recycling technology is designed for productivity. New force feeding system plus single screw extruder with compactor significantly increased raw material intake efficiency. New type of pelletizing is more user-friendly and low maintenance.

Features & Advantages

High efficient vacuum keeps the IV drop minor

Optimized screw design avoids yellowing

Streamline the process

Pre-drying-free technology saves energy up to 35%

Minimize the investment

Technical Parameter

Double Layer Disc

Double Layer Disc for excellent degassing

Double disc and mixing dryer, mixing and drying bottle flakes

Instruction: The strong friction and heat generated by the double blade plates cause the material to dry and shrink; the feeding amount is automatically controlled, and there are two sets of temperature monitoring systems.

Blade material: D2 Bi-metal

Steel thickness:8mm

Roots Vacuum Pump

Fast start-up, low power consumption, low operation and maintenance costs, high pumping speed, high efficiency, insensitive to the small amount of water vapor and dust contained in the pumped gas, and a larger pumping rate in the pressure range of 100 to 1 Pa. Can quickly remove the suddenly released gas.

Under water cutting system

Since the plastic is scraped off by the blade in the melt state and solidified after being cooled by circulating water, the pellets under the melt will not form any dust, and the pellets are of regular shape and uniform size, and the packaging and transportation are more convenient.

The molten plastic is directly cut into pellets after flowing out of the die hole, and is taken away by the cooling water in time. As long as the temperature and flow rate of the circulating water are controlled, the crystallinity of the product can be controlled. The quality of the pellets is very stable, and the transparency and gloss are very stable. Degree is higher.

Since the pelletizing is carried out under water, the oxidation of the product in the air can be avoided.

A plastic recycling and granulating machine is a type of equipment used to recycle plastic waste into granules or pellets that can be reused in manufacturing new plastic products. The machine typically works by shredding or grinding the plastic waste into small pieces, then melting and extruding it through a die to form pellets or granules.

There are different types of plastic recycling and granulating machines available, including single-screw and twin-screw extruders. Some machines also include additional features such as screens to remove impurities from the plastic waste or cooling systems to ensure the pellets are solidified properly.

Plastic recycling and granulating machines are commonly used in industries that generate large amounts of plastic waste, such as packaging, automotive, and construction. By recycling plastic waste, these machines help reduce the environmental impact of plastic disposal and conserve resources by reusing materials that would otherwise be discarded.

Lithium battery recycling equipment is a type of equipment used to recycle and recover valuable materials from lithium-ion batteries, which are commonly used in electronic devices such as smartphones, laptops, and electric vehicles. The equipment typically works by breaking down the batteries into their constituent parts, such as the cathode and anode materials, electrolyte solution, and metal foils, and then separating and purifying these materials for reuse.

There are different types of lithium battery recycling equipment available, including pyrometallurgical processes, hydrometallurgical processes, and mechanical processes. Pyrometallurgical processes involve high-temperature processing of the batteries to recover metals such as copper, nickel, and cobalt. Hydrometallurgical processes use chemical solutions to dissolve the battery components and recover metals, while mechanical processes involve shredding and milling the batteries to separate the materials.

Lithium battery recycling equipment is important for reducing the environmental impact of battery disposal and conserving resources by recovering valuable metals and materials that can be reused in new batteries or other products.

In addition to environmental and resource conservation benefits, lithium battery recycling equipment also has economic benefits. Recovering valuable metals and materials from used batteries can reduce the cost of producing new batteries, as well as create new revenue streams for companies involved in the recycling process.

Furthermore, the increasing demand for electric vehicles and other electronic devices is driving the need for a more efficient and sustainable battery recycling industry. Lithium battery recycling equipment can help meet this demand by providing a reliable and cost-effective way to recover valuable materials from used batteries.

However, it’s important to note that lithium battery recycling is still a relatively new industry, and there are challenges to overcome in terms of developing efficient and cost-effective recycling processes. Additionally, proper handling and disposal of battery waste is crucial to avoid environmental and health hazards. Therefore, proper regulations and safety measures must be in place to ensure the responsible handling and recycling of lithium batteries.
