SRL500/1000 Hot and Cold Mixing Unit

The SRL500/1000 Hot-Cold Mixer Unit is a professional mixing equipment designed for efficient blending, heating, and cooling of plastic raw materials (PP, PE, PVC), ideal for plastic processing industries like sheet extrusion and injection molding.​

● As a flagship model of SRL series hot-cold mixer unit, it integrates a high-speed hot mixer (500L) and a low-speed cold mixer (1000L), forming a seamless workflow that meets the strict mixing demands of Plastic hot-cold mixing unit applications. The hot mixer uses a stainless steel rotor with special blades, generating high shear force to heat materials to 80-120℃ quickly-ensuring uniform dispersion of additives (fillers, stabilizers) in plastic pellets, a key advantage over single-mixer systems in SRL series hot-cold mixer unit designs.​

● The cold mixer, with a large 1000L capacity, rapidly cools mixed materials from 120℃ to 40-50℃ via water jacket cooling, preventing material agglomeration and maintaining particle shape-critical for subsequent plastic processing steps. This hot-cold combination reduces mixing time by 30% compared to traditional equipment, aligning with the high-efficiency standards of Plastic hot-cold mixing unit. The unit's total mixing capacity reaches 500-800kg/h, suitable for medium-to-large batch production.​

● Equipped with a frequency conversion control system, it adjusts hot mixer speed (800-1500rpm) and cold mixer speed (50-150rpm) based on material properties-lower speeds for fragile pellets, higher speeds for high-viscosity mixtures, a flexibility inherent in SRL series hot-cold mixer unit. A PLC control panel with a 7-inch touchscreen enables automatic operation: it starts the hot mixer, transfers materials to the cold mixer via a pneumatic valve, and triggers cooling-minimizing manual intervention.​

● Safety and durability are prioritized: the hot mixer has over-temperature protection (auto-shuts at 150℃), and both mixers feature pressure relief valves to prevent equipment damage. The stainless steel inner liners resist corrosion and are easy to clean, extending the unit's service life to 8-10 years-meeting the reliability requirements of Plastic hot-cold mixing unit. The unit's compact layout (3500×2200×2800mm) saves workshop space, with low noise operation (≤85dB).​

● Optional accessories: a dust collection system (reducing raw material loss), a material level sensor (auto-alerts when mixing is complete), and a recipe storage function (saves 50+ mixing parameters). Built with premium components (Siemens frequency converter, ABB motor), it has an average failure rate below 2% per year. A 12-month warranty covers parts and labor, with on-site maintenance support-making it a cost-effective choice for plastic processors seeking efficient, stable raw material mixing.
