The Use Of Small Twin Screw Extruder
- Small and medium-sized modification factories use it to undertake small batch custom orders from downstream customers such as automotive parts and electronic appliances, breaking through the bottleneck of large production lines with flexible production capacity.
- Laboratories in universities and research institutes utilize it to establish a comprehensive verification chain, spanning from formula design to the preparation of physical granules.
- A manufacturer of masterbatch and additives, utilizing it to complete small-scale trial production of new products and provide samples to customers.
- No matter the scenario, a small twin-screw granulator with excellent quality and flexible configuration serves as a fulcrum, leveraging controllable inputs to gain process autonomy.
The Advantages Of Our Extruder
Micro-dosing reduces the cost of trial and error.
- The consumption of materials for a single startup of a large twin-screw extruder often starts at hundreds of kilograms. For the research and development of new materials in the formula verification stage, this consumption is a continuous loss.
- The small twin-screw granulator requires less than 200g, which means that the same batch of raw materials can be divided into multiple variable groups for parallel verification, significantly improving R&D efficiency and minimizing raw material waste.
Screw modularization, one machine adapts to hundreds of formulas.
- Different materials have varying requirements for shear strength, residence time, and mixing methods.
- Users can adjust the arrangement and type of the conveying section, melting section, mixing section, exhaust section, and homogenizing section according to the recipe.
Strict material system
- The screw element undergoes overall nitriding treatment, achieving a surface hardness of RHC60~62; the barrel is lined with high-rigidity alloy steel, ensuring minimal wear under continuous operation conditions.
- The transmission case adopts a high-torque graded transmission design, and the servo motor direct drive solution reduces energy consumption by approximately 18% compared to conventional variable frequency drives, while also avoiding speed drift caused by belt slippage.
Process closed loop
- Equipping a vacuum devolatilization system after the exhaust section can effectively remove residual moisture and low molecular weight volatiles from the melt, eliminating internal pores and surface defects in the particles.
PLC control
- The complete machine control system has reserved a digital interface that can be connected to the laboratory information management system, enabling automatic archiving of process data such as shear rate, average residence time, exhaust vacuum degree, and temperature curves of each section for each batch.
- This is not just a granulator, but also a process database that can be accumulated, traced, and optimized. When customers require proof of process capability during audits, you have complete data assets at your disposal, rather than vague recollections of experience.
Due to the influence of details such as temperature, material, and LD, some materials cannot be satisfied by the MT series. In such cases, the MH and MU series are the best choices.
MH series: When dealing with complex materials, the torque needs to be increased
| Type | L/D | Main Power(kw) | Screw Diameter(mm) | Screw Speed (rpm) | Output(kg/h) |
|---|---|---|---|---|---|
| MH25 | 28~48:1 | 7.5 | 25 | 600 | 5~25 |
| MH36 | 28~62:1 | 30 | 35.6 | 600 | 40~80 |
MU series: particularly complex materials require strong torque support
| Type | L/D | Main Power(kw) | Screw Diameter(mm) | Screw Speed (rpm) | Output(kg/h) |
|---|---|---|---|---|---|
| MU25 | 28~48:1 | 15 | 25 | 600 | 5~30 |
| MU36 | 28~62:1 | 37 | 35.6 | 600 | 40~85 |
