The RLB Two Stage Reciprocating &amp; Single Screw Pelletizing Line (also known as the reciprocating kneader + single-screw tandem pelletizing unit) is specifically engineered to meet these challenges while delivering up to 25 % energy savings compared to conventional extruders.<\/p>\n<p dir=\"auto\">This advanced two-stage system combines a high-intensity reciprocating single-screw mixer (first stage) with a low-shear single-screw extruder (second stage) connected via T-type distribution. The reciprocating motion provides powerful radial and axial mixing, short material residence time, high filler loading capacity, and superior self-cleaning performance \u2014 ensuring uniform dispersion without temperature peaks that could degrade sensitive polymers.<\/p>\n<h2>Principaux avantages en mati\u00e8re d&#039;ing\u00e9nierie<\/h2>\n<ul dir=\"auto\">\n<li><strong>Superior Mixing Performance<\/strong>: Both radial and axial mixing action plus excellent injection of liquid additives deliver homogeneous compounds with minimal shear heat.<\/li>\n<li><strong>Energy-Efficient Design<\/strong>: Proven 25 % lower power consumption than standard extruders while maintaining high throughput.<\/li>\n<li><strong>Precise Temperature Control<\/strong>: No melting temperature peaks \u2014 critical for heat-sensitive materials like LSZH and XLPE.<\/li>\n<li><strong>High Filling Capacity &amp; Quick Changeover<\/strong>: Excellent self-cleaning properties and short conversion time maximize equipment utilization and reduce downtime.<\/li>\n<li><strong>Fully Automated System<\/strong>: Gravimetric weighing for granules\/powders, forced feeding, and precise liquid dosing combined with MMI + PLC control for recipe storage, real-time monitoring, and simple operation.<\/li>\n<li><strong>Flexible Downstream Options<\/strong>: Water-ring cutting, eccentric water-mist cutting, plus various packaging solutions (bin collecting, ton-bag, automatic weighing &amp; bagging).<\/li>\n<\/ul>\n<p dir=\"auto\">The result is high-quality, dust-free pellets with excellent flow characteristics and consistent physical properties \u2014 exactly what cable manufacturers need for high-voltage, flame-retardant, and specialty applications.<\/p>\n<h3 dir=\"auto\">Technical Specifications (RLB Two Stage Reciprocating &amp; Single Screw Pelletizing Line)<\/h3>\n<table>\n<thead>\n<tr>\n<th data-col-size=\"lg\">Mod\u00e8le<\/th>\n<th data-col-size=\"sm\">Reciprocating Screw Dia.
