High-Efficiency Intelligent Manufacturing: 8-T/Hour Extrusion Granulation Production Line

At the end of August 2025, Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd.'s customized 8-ton/hour extrusion granulation production line for a Malaysian client completed full-process commissioning and officially entered the mass production stage. With its core advantages of high capacity, high precision, and low energy consumption, this production line perfectly adapts to local raw material characteristics and environmental standards. Its modular design and intelligent configuration have become a typical model for high-end extrusion granulation equipment exported overseas. Production Line Core Configuration and Process Link The entire production line follows a closed-loop process design of "pre-treatment - mixing - granulation - post-treatment - finished product packaging." Each unit of equipment is precisely matched and works in synergy for high efficiency, achieving an automation level of over 90%. Raw Material Pre-treatment and Mixing Unit The raw material conveying system uses three belt conveyors of different specifications, respectively responsible for raw material transfer, intermediate material connection, and return material conveying. The conveyor belt width is adapted to the 8-ton/hour capacity requirement, ensuring smooth operation without material spillage, and improving conveying efficiency by 15% compared to conventional equipment. The core mixing equipment uses two 1.2×3.0 meter twin-shaft horizontal mixers with counter-rotating blades, ensuring a mixing uniformity error of ≤3%. The equipment is equipped with a variable frequency speed control system, allowing for flexible speed adjustment based on raw material moisture content and proportions, ensuring the moisture content of the mixed materials is stably controlled within the optimal granulation range of 28%-32%. The core granulation unit utilizes four 2.5-type double-roller extruders operating in parallel. Each machine has a capacity of 2.2 tons per hour, achieving a total designed capacity of 8 tons per hour when operating together. The rollers are made of high-chromium alloy, achieving a hardness of HRC60 or higher after quenching treatment, resulting in three times the wear resistance of ordinary materials and extending the service life to over 8000 hours.
