Product Description

Twin-screw extrusion unit underwater pelletizing

This lab twin screw plastic extrusion machines consisted of transmission device, extrusion device, heating and cooling system, electric control system, etc.  

The lab twin screw plastic extrusion machines appropriate for the mixing processing experiment of engineering plastics, modified plastics, waste plastics and color masterbatch etc., suitable for all kinds of plastic extrusion granulation, plasticizing homogeneous, color proofing, filling modification, etc.

Parameters:

Output	According to the raw material formulation process
Temperature range	Normal temperature ~300ºC
Screw diameter	Φ20 mm
Length diameter ratio	1:40 optional
Screw direction	Rodent type, parallel and same direction
Screw rotation speed	0-280rpm
Screw material	The mandrel is made of 40CrNiMoA chromium-molybdenum alloy tool steel, and the threaded components are made of W6Mo5CR4V2 wear-resistant alloy steel, with a hardness of HRC60, with conveying blocks, mixing blocks, shearing blocks, banburying blocks, kneading blocks, countercurrent blocks, building block series components, and the mandrel is gradually splined and can be combined according to any material ratio to meet the needs of different extrusion processes
Combination method	The combination mode of the screw suite is building block spiral and the machine barrel is multi-section type, with self-cleaning function
Heating zone	5 cast aluminum heaters fixed at  barrel, 1 heater at handpiece, each section with 1 kW heating power, external covered with safety protective wind hood
Cooling zone	The entire section of the barrel adopts a soft water circulation cooling system, each segments of cooling water flow rate is adjustable, equipped with self-priming circulating water pump, 304 stainless steel water storage tank, inlet and outlet water pipes and the electromagnetic valve components,etc. Can implement independent temperature control and cooling for each section of the barrel unit
Electric control system	PLC programmable color touch screen, man-machine interface operation system, extrusion process can be displayed and monitored dynamically, including temperature control, driving, speed, pressure, interlocking and intercontrol function
Power	3∮, AC380V, 50Hz Three-phase five-wire

Features:

1. The screw diameters of lab twin screw plastic extrusion machines are 20, 25, 30 (optional), and the length diameter ratio is 10~30 times can be optional.
2. The material of the screw and the charging barrel is 40CrNiMo special tool steel which is hard & wear resistant and has been processed through nitriding, tempering, chromeplate and super-precision grinding.
3. The twin screw adopts the compound mode of building block, including the conveying building block of screw thread, kneading building block, shear building block and remilling etc. The screw suite consisting of these kneading blocks of different alternate angles and width can meet different shearing forces and mixing effects required by multi materials production and can carry out the craft scheduled combination in accordance with any material.
4. The twin screw component combination has the self clean function like mutual cleaning up etc. at high-speed rotating, reducing material wastes during the experimental process and saving clean-up time.
5. The charging barrel is heated by the cast copper heater which is simply maintained and easily installed and costs little heating time & high heat rate, ensuring the required temperature. The charging barrel adopts soft water circulation cooling with a good cooling effect.
6. The host machine transmission box and torque divider are put into one of tight structure, steady operation and large torque, appropriate for any output of power of high shear rate.
7. The dies adopt the quick connecting loop which makes the fast dismounting, easily connection to the downstream equipment and time and labor-saving transfer test.
8. The optional spreader plate and the filter mesh enclosure prevents non-moltened particles and impurities to improve the melt pressure and guarantee plasticizing quality.
9. This machine has a removable stainless steel cooling water sink and its guide wheel device and drying machinery with simple and fast assembly and good effect of water cooling and water removal dryness.
10. The handpiece is equipped with a quick converter and a high precision melt temperature & pressure transducer, the pressure of the detecting handpiece being accurate and reliable. The interlock joint control intelligent pressure control system has the function of automatic alarm and automatically-controlled stop.
11. PLC programmable color touch screen, man-machine interface operation system, can dynamically display and monitor extrusion process, including temperature control, driving, pressure, interlocking spreading function.
