Welcome to ANDA
The Anda Machinery SRL-Z series high-speed heating and cooling mixer unit is the premier solution for raw material pre-treatment in plastic extrusion. It is widely used for the homogeneous compounding, coloring, and drying of PVC powder, WPC formulations, and various plastic additives. With its integrated hot-and-cold combination design, it ensures maximum process efficiency and excellent bulk density control before extrusion.
SRL-Z Series High-Speed Mixer Unit For PVC/WPC Powder
Dual-Pot Synchronized System: The upper 500L hot mixer utilizes high-speed friction to rapidly blend and pre-heat materials, while the lower 1000L cold mixer cools the mixture efficiently to eliminate residual gases and prevent caking.
Premium SUS304 Construction: Both the inner wall of the pots and the highly optimized mixing blades are crafted from premium SUS304 stainless steel. The surface is mirror-polished, ensuring extreme wear resistance, corrosion resistance, and zero material contamination.
Advanced Pneumatic Discharging: Equipped with heavy-duty pneumatic cylinders for automatic discharge. The discharge valves seal tightly with no leakage and open completely for zero-residue material transfer.
High-Torque Reliable Drive: Powered by industrial-grade copper core motors featuring soft-start capability to reduce grid impact and ensure stable, low-noise operation under continuous full-load conditions.
Dynamic Balance Testing: All mixing blades undergo strict static and dynamic balancing tests to eliminate vibration and significantly prolong the lifespan of main bearings and seals.
