This solution establishes a fully enclosed, dust-free dry-blend compounding and multi-point automated feeding system engineered specifically for rigid and flexible PVC pipe, profile, cable compound, and sheet manufacturers. Centered around a high-intensity heating and cooling mixer combination unit (SRL-Z Series), it integrates negative-pressure dust-tight bag tipping stations, loss-in-weight or volumetric micro-additive dosing, and an automated closed-loop pneumatic transfer network delivering finished dry blends directly to multiple extruder feed hoppers.<\/p>\n
PVC dry-blend compounding is notorious for severe shop-floor dusting, heavy plasticizer vaporization, and erratic additive dispersion. Manual bag dumping and open-trough mixing release hazardous airborne lead\/calcium-zinc stabilizer dust, titanium dioxide, and calcium carbonate fines into the ambient environment, posing severe health hazards and triggering cross-contamination. Furthermore, improper cooling after high-speed hot mixing leads to caking, thermal degradation, and inconsistent plasticizer absorption. This engineered solution encloses the entire process from raw material intake to extruder throats, ensuring worker safety, 100% dust containment, and micro-scale additive homogenization.<\/p>\n","protected":false},"excerpt":{"rendered":"
