Parallel Twin-Screw Extruder for Plastics Profile

Product Name : ATE Parallel Twin Screw Extruder

Product Description

Typical applications:

Engineering plastics, masterbatch, filler, TPE, TPR, TPV, direct extrusion

ATE Parallel Twin-Screw Extruder

ATE series parallel twin screw extruder is driven by motor, torque distribution gearbox, processing part, temperature control device, mold part and downstream grain cutting system.

ATE twin screw extruder adopts the principle of modular design and standardized production of components, so as to present stable and reliable performance.

With the principle of modularization, ATE series extruding machines can provide highly customizable solutions according to customers' process and special requirements. Based on different output torque levels, there are two types of ATE extruders: basic type and efficiency type.

ATE co-rotating twin screw extrusion machinery combines a variety of cutting systems, such as water strands cutting system, die surface cutting system and underwater cutting system.

Relay control and PLC control are both used in ATE electrical control system. All key electrical components are European branded to ensure significant stable performance of the control system.

Screw loader

Screw loader for loading dried flakes up into the extruder. Screw Loader to load PP flakes into extruder’s feeding hopper. Loading motor power: 2.2 kw. Conveying pipe made with stainless steel material, pipe inner thickness is 2mm, pipe diameter is 102mm.

Volumetric Feeder

Special design. No blockage. With ABB/Schneider inverter.

Intelligent Control

Intelligence Start: One button only Following set logistical sequence and materials processing requirement, interlocked system modules can start by "one button only” Intelligence Stop: One button only Each related modular part in ACS system available to shut down by only one button. Emergency Stop Emergency stop function is available in ACS system in case that uncertain risk occurred during machine running.

Remote Monitoring And Information Transmission

System program remote monitoring and transmission system,bluetooth both are available for ATE system realizing functions of remote monitoring and information transmission.

Twin-screw Extruder

Screw diameter: 71 mm. L/D = 40 Main drive motor: AC 132 Kw. Speed controlled by ABB/Schneider inverter. Rotary speed of extruder: 60～600rpm Processing section (barrels and screw elements).

Silo Light Tube

Can watch the working state of the machine.

Heater

Cast copper heater.

Heating power: 36kw, equip with 1.1kw heating blower.

Soft Water Cooling System

Material of input and output pipes is stainless steel. Manual valves to adjust flowing rate of cooling water; solenoid valves are to control opening and closing of cooling water flowing in.

2 In 1 Option

This model combines our self-developed self-cleaning filter.The new SCF self-cleaning filtration system makes non-stopping recycling extrusion, especially suitable to highly contaminated materials re-pelletizing. SCF filtration system can handle and remove up to 5% contaminates in the melt flowing, can separate the contaminates as: paper, wood, aluminum, unmelted plastic and rubbers etc.

Melt filtration

A regular single-plate/ piston double-station screen changer or non-stop double-plate/ piston four-station can be installed on head of extruder to present significant filtration performance. the requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules.

Pelletizing

Die-face water ring pelletizing system set as the standard granulating method in ACSS-HTM system. Self-adjusting pelletiziin head for the best granulate quolity and long uptime thanks to consistently correct blades oressure. RPM of rotatory blades is automatic based on melt extruding pressure.

Vibration Dry

Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.

Plastic Particles

Final output: plastic particles.
