High-Speed Dispersion
The 45 kW, 900 RPM hot mixer rapidly disperses PVC resin, filler and additives while generating self-friction heat.

Product Overview
This 200/500L hot-cold mixing unit is professionally optimized and specially designed for the compound mixing process of PVC powder, calcium carbonate and various functional additives. It adopts industry-standard graded parameter matching design, with perfectly calibrated tank volume, stirring speed and cycle time between hot mixing and cold mixing modules tailored for plastic formula mixing. The hot mixer realizes high-speed thermal homogenization and full dispersion of PVC powder, calcium carbonate fillers and additives, while the cold mixer completes low-speed constant-temperature cooling and material conditioning, forming a mature closed-loop continuous production process exclusive for plastic compounding. It eliminates production disconnection, material uneven mixing and capacity attenuation caused by mismatched unit parameters, delivering a sustained and stable hourly output of 280~320KG.

Core Advantages
Right-Sized Batches
A 150 L effective hot-mixer volume handles 70–80 kg batches for stable 280–320 kg/h output.
Controlled Cooling
The 500 L cold mixer combines a 7.5 kW, 100 RPM drive with jacket water for even, gentle cooling.
Repeatable Processing
Thermocouple monitoring and adjustable 8–12 minute cycles support consistent batches.

Frequently Asked Questions
What is the hourly capacity?
Stable output is 280–320 kg/h with 8–12 minute cycles and 70–80 kg hot-mixer batches.
How is the hot mixer heated?
Self-friction heating is standard; electric or steam heating can be customized.
How does the cold mixer cool material?
Jacket circulating water removes heat while a thermocouple monitors temperature.
What are the mixer speeds?
Maximum speed is 900 RPM for the hot mixer and 100 RPM for the cold mixer.
What are the motor powers?
The hot mixer uses 45 kW and the cold mixer uses 7.5 kW.
Can mixing time be adjusted?
Yes, normally within 8–12 minutes for PVC, modified plastics, rubber materials and additives.
What are the effective volumes?
The hot mixer is 150 L effective with a 70–80 kg batch; the cold mixer is 375 L effective.
Can the configuration be customized?
Yes. Heating, cooling, speed, feeding, discharge and controls can be tailored.
How is temperature measured?
Both stages use thermocouples for real-time monitoring.
What are the service and delivery terms?
The standard offer includes a one-year warranty and lifetime support; typical delivery is 15–25 working days, subject to configuration.
