PP modified plastic granulation requires stable extrusion pressure, precise melt metering and consistent material conveying, which directly determine pellet uniformity, product stability and production efficiency. As a core auxiliary extrusion device, the melt pump has become an indispensable key equipment for high-efficiency and high-quality PP modified granulation lines, solving common pain points of traditional extruder granulation processes.
Installed between the extruder and the die head, the melt pump features high-precision gear transmission, realizing constant-pressure and stable conveying of PP melt. Different from the unstable discharge of single-screw extruders caused by temperature and load fluctuations, the melt pump isolates upstream pressure pulsations, stabilizes die head pressure within a tiny fluctuation range, and ensures uniform size and density of modified PP pellets. It effectively avoids defective products such as uneven particles and hollow pellets caused by melt flow instability.
Moreover, the melt pump improves production capacity and energy efficiency of PP granulation lines. It enhances plasticizing uniformity of modified PP materials, increases continuous production stability, and boosts output by 10-15% compared with traditional processes. With flexible installation and strong compatibility, it adapts to various PP modified granulation line layouts, suitable for new production lines and old equipment renovation, bringing significant cost-saving and quality-upgrading benefits for plastic processing enterprises.
