Heavy-Duty Bag Checkweigher & Controller

Product Essence: Precision Meets Industrial Might

Shanghai Guangzhi Automation’s Heavy-Duty Bag Checkweigher System delivers ±0.05% weighing accuracy for 50-2000kg sacks (cement, ore, grains) in extreme conditions. Integrating military-grade load cells, AI-powered drift compensation, and ATEX-certified dust containment, it achieves 40 bags/minute throughput while enabling real-time quality control in mining, chemicals, and bulk logistics.
