In the field of industrial mixing equipment, the highest praise we receive is not just good reviews on the equipment — it’s our customers’ long-term repeat orders.
Recently, one of our valued clients from Malaysia visited LRMIX (LaiHong Machinery) again. Their purpose was to expand their plastic color masterbatch production line. After purchasing their first LRMIX screw kneader in 2023 and personally experiencing the machine’s excellent stability and performance, they decided this year to order another identical machine!
Application
So, what materials is this kneader actually designed to mix? It is specially built for the color masterbatch and plastics industry. It excels at perfectly blending plastic pellets with color pigments. Melting plastic pellets and then mixing in powders is extremely challenging, but our carefully engineered Sigma-type blades and optimized clearances ensure that every batch achieves 100% uniform dispersion.Key Features & Advantages
Here’s why this kneader is the ideal choice for large-scale color masterbatch production lines:
- Large Capacity — The total volume reaches 1230L, with a working volume of 800L. It is designed for high daily output.
- Efficient Granulation — The machine can be directly paired with an extruder to create a complete production line. After kneading, the material is fed through the screw directly into a single-screw or twin-screw extruder for pelletizing. Multi-zone heating prevents the plastic from solidifying inside the screw. The entire process requires almost no manual intervention, greatly improving efficiency and final product quality.
- Dust-Free & Zero Pollution — Unlike traditional high-speed mixers that create heavy dust, our kneader features a hydraulic sealing lid. Once closed, the chamber becomes a fully sealed environment, effectively eliminating powder dust and keeping the workshop clean.
- Excellent Wear Resistance & Easy Cleaning — All material-contact parts are made of thickened 304 stainless steel with mirror polishing, ensuring zero contamination and making cleaning much easier — even with sticky plastics. For black, blue, or other non-sensitive colors, carbon steel is also available as a more cost-effective and highly wear-resistant option.
- Optimized for Plastics — The special design allows smooth and efficient processing of various plastic colors and formulations.
