Dry Mortar Packing Machine with Ultrasonic Heat Sealing for Valve Bags – High Accuracy 5-7 T/h Capacity

Product Overview

Our Dry Mortar Packing Machine with integrated Ultrasonic Heat Sealing technology represents the latest advancement in valve bag packaging for powder materials. Delivering a high output capacity of 5-7 tons per hour, this packing solution combines precision weighing with advanced sealing technology to ensure accurate, clean, and moisture-proof packaging of dry mortar, cement, and other construction powders.

Advanced Ultrasonic Heat Sealing Technology

The integrated ultrasonic sealing system uses high-frequency vibrations to generate heat precisely at the seal interface, fusing the valve bag layers without physical contact. This innovative approach creates a hermetic, airtight closure that prevents moisture ingress and product contamination, essential for hygroscopic materials like dry mortar, gypsum, and putty powder. Unlike conventional heat sealing, ultrasonic technology produces no thermal byproducts, requires no consumables, and results in a tamper-proof, dust-tight seal that maintains product quality during storage and transport.

1.High-Accuracy Digital Weighing System

The machine features a PLC-controlled digital weighing system with high-precision sensors, achieving accuracy of ±0.2%. The advanced multi-stage feeding mechanism with fast, medium, and slow phases ensures optimal filling precision for every bag. This precision minimizes material waste and product giveaway, ensuring each bag meets exact weight specifications and trade standards.

2.Dust-Free and Environmentally Friendly Operation

The fully sealed machine design, combined with pneumatic air flotation filling, ensures virtually dust-free operation. Low air pressure technology significantly reduces dust emission compared to conventional packers, creating a cleaner and safer working environment for operators. An integrated dust removal port further enhances environmental compliance.

3.High Capacity for Industrial Production

With a packing capacity of 5-7 tons per hour, this machine is ideal for medium to large-scale dry mortar production lines. The valve bag filling spout accommodates standard valve bags from 10kg to 60kg, and the automatic bag detection system ensures seamless, continuous operation.

Durable Construction for Continuous Operation

Built with high-strength steel structure and wear-resistant components, this dry mortar packing machine is designed for demanding industrial environments. The contact parts are available in 304 stainless steel for corrosion resistance when handling various powder materials. The robust construction ensures reliable, long-term performance with minimal maintenance.
