25kg Open Pocket Automatic Metering Packaging Machine

The 25kg open pocket automatic metering packaging machine is a purpose-built industrial bagging solution designed for accurate, high-speed quantitative filling of dry powder materials, construction chemicals, and bulk granular products. Manufactured in a dedicated production factory with strict quality standards, this equipment addresses the core requirements of modern powder packaging lines: weighing precision, operational reliability, material compatibility, and minimal dust emission.

This machine is widely used across construction material manufacturing, chemical processing, building materials distribution, and dry mix mortar production. Whether you are packaging wall putty powder, dry mortar, cement-based additives, thickening agents, or other free-flowing and semi-free-flowing powders, this system delivers consistent bag weights, repeatable sealing quality, and production throughput suited to medium and large-scale industrial operations.

What This Machine Packages

Сайт 25kg open pocket automatic metering packaging machine is engineered to handle a broad spectrum of materials. Common applications include:

• Wall putty powder and dry powder putty
• Dry mortar and cement-based blends
• Tile adhesive powder and gypsum products
• Thermal insulation mortar and plaster
• Chemical additives and construction auxiliaries
• Fine granular materials with variable flow characteristics

The open pocket (open mouth bag) format makes it compatible with woven PP bags, kraft paper bags, and PE-lined bags commonly used in the construction and chemical industries. Bag weight ranges are adjustable, and the machine accommodates different bag dimensions without requiring significant mechanical reconfiguration.

Available Valve and Opening Configurations

One of the defining strengths of this packaging machine is its configurable valve and opening system. Different powder materials have different flow behaviors, particle sizes, densities, and hygroscopic properties. A single mechanism cannot serve all materials equally. For this reason, the machine is available with multiple filling and sealing valve options:

1. Pneumatic valve port — ideal for ultra-fine and highly aerated powders requiring controlled air-assisted discharge
2. Ultrasonic sealing valve port — delivers hermetic, heat-free sealing suitable for moisture-sensitive materials
3. Impeller type or air floatation type — suited for dense, semi-granular, or abrasive powders requiring mechanical force for consistent discharge and densification
4. Spiral valve — designed for materials that require controlled rotational discharge to prevent bridging and clogging
5. Screw opening — provides metered auger-driven filling for cohesive, non-free-flowing powders with precise volume or weight control
6. Gravity valve port — leverages material weight for straightforward, high-speed filling of free-flowing granular products
7. Gravity opening — a simplified gravity-based discharge suitable for high-throughput, low-viscosity powder applications
8. Belt type opening — offers smooth, adjustable-speed discharge for materials sensitive to impact or compression
9. Big bag option — extends machine capability to large-format FIBC or jumbo bag filling for bulk logistics and export packaging

Choosing the correct valve configuration is critical to achieving the specified bag weight accuracy, minimizing dust generation, and maintaining long-term mechanical reliability. The factory’s technical team provides consultation to help buyers match the right configuration to their specific material and production requirements.

Machine Design and Construction

The machine integrates an automatic weighing device, a material feeding mechanism, a bag clamping unit, and an electrical control system into a single, space-efficient structure. Key design characteristics include:

• High-precision electronic load cells for real-time weight measurement and automatic correction
• PLC-based control with a human-machine interface for simple operation and parameter adjustment
• Fully enclosed or semi-enclosed filling zones to minimize powder escape and improve workplace air quality
• Heavy-duty frame construction for continuous industrial use across multiple shifts
• Compatibility with upstream conveying equipment such as screw conveyors and bucket elevators, enabling full production line integration

The control system supports packaging weight adjustment, filling speed regulation, and diagnostic feedback. Operators can set target weights, monitor fill cycles, and receive alerts for deviations without requiring advanced technical training.

Integration with Complete Packaging Lines

The 25kg open pocket automatic metering packaging machine is designed for standalone use or integration within a complete automated packaging line. It can be connected to:

• Screw conveyors or bucket elevators for material supply from silos or hoppers
• Automatic bag conveyors and folding machines for downstream transport
• Bag sewing machines or heat sealing units for bag closure
• Checkweighers for post-fill weight verification
• Palletizers for automated stacking and logistics preparation

When configured as part of a full line, the system enables near-continuous production with minimal manual intervention, reducing labor costs and improving output consistency.

Related Equipment in the Product Range

This factory also manufactures and supplies a comprehensive range of complementary packaging machines to serve different production scales and material types:

• 50kg independent bag packaging machine for high-weight bulk applications
• 10L back seal packaging machine for smaller-format liquid or semi-liquid products
• 200L fully automatic high-speed packaging machine for large-volume industrial outputs
• 18kg double-nozzle dry powder packaging machine for dual-stream, high-efficiency powder filling
• 25kg thickening agent packaging machine for specialized construction additive materials
• Metal long tube packaging machine for cylindrical or elongated packaging formats
• Double-chamber vacuum packaging machine for oxygen-sensitive or moisture-sensitive materials
• Zipper vertical packaging machine for retail-oriented resealable bag formats
• Open vertical packaging machine for flexible film bag production and filling

This product range allows buyers to source multiple machine types from a single manufacturer, simplifying procurement, spare parts management, and after-sales coordination.

After-Sales Service and Technical Support

The factory provides complete after-sales service and technical support to all customers. Support includes installation guidance, commissioning assistance, operator training, troubleshooting, and access to replacement parts. The company’s after-sales team is structured to respond to both routine maintenance queries and urgent production issues, minimizing machine downtime.

Technical consultation is available before purchase to ensure the correct machine model and valve configuration are selected for the buyer’s specific material, bag format, and production throughput requirements. Given that different materials require different machine configurations, direct consultation with the sales and engineering team is strongly recommended before finalizing an order.

Who Should Consider This Machine

This packaging machine is appropriate for manufacturers and processors operating in the following sectors:

• Dry mix mortar and construction material production
• Wall putty and gypsum product manufacturing
• Chemical additive and powder compound processing
• Fertilizer and agricultural input packaging
