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

Lumps or thick flakes after crushed, conveyed into the single screw extruder by screw loader, then, compress, plasticize in the extruder and removed volatiles and moisture by vacuum system, after filtering through the filtration system, to pelletize into granules. Depending on the different screw diameters of single screw, the typical capacity can cover from 100kg/h to 1000kg/h,Loading motor power: 2.2 kw. Conveying pipe made with stainless steel material, pipe inner thickness is 2mm, pipe diameter is 102mm.

Main feeder (Volumetric)

It will feed the materials into the extruder. There is a stirring screw to avoid material’s blockage at the bottom of the feeder. Feeding hopper with level indicator.
If  you want to compound the materials, side feeders are optional.

SILO LIGHT TUBE

Can watch the working state of the machine.

proimages/product/ATE_pelletizing_machine_(5).JPG
Gearbox

The gearbox will reduce the motor speed to the screw shafts speed and distributes it to the two output shafts.Low-noise, high torque output.

Infrared heaters

Cast copper heater, easy to assemble and disaassemble. Faster heating and low energy waste.

proimages/product/ATE_pelletizing_machine_(8).jpg
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.

None-stop Piston Type Filter

* 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.
* Long screen lifetime, lower screen change frequency: Long filter lifetime owing to large filter areas. 
* Easy to use and none-stop type: easy and quick screen change and do not need to stop the running machine.
* Very low operation cost.

proimages/product/ACS-H_pelletizing_machine_(12).jpg
Plate type filter

The Plate type filter is made in a continuous type with two filter plates. There is at least one filter working when the screen is changing.Ring-shaped heater for consistent and stable heating.
