The 25kg valve bag crack-resistant mortar packaging machine is an automatic industrial bagging system designed to fill, seal, and discharge dry powder construction materials including crack-resistant mortar, dry mix mortar, cement powder, putty powder, and gypsum into standard 25kg valve bags with high weighing accuracy and minimal dust emission.

What Is a 25kg Valve Bag Mortar Packaging Machine?

A 25kg valve bag packaging machine is an automated filling and sealing unit built for bulk dry powder materials used in construction and building material industries. It accepts valve-type bags through a filling spout, uses a computerized weighing system to dispense the precise amount of material, and releases the filled bag automatically once the target weight is achieved.

This machine is engineered for materials that have variable flow characteristics, such as crack-resistant mortar, dry mix mortar, tile adhesive, wall plaster, putty coating, fly ash, calcium carbonate powder, quartz sand, and similar fine to medium granular powders. Because different materials behave differently during filling, this packaging machine is offered with multiple valve and opening mechanism options, each suited to specific material density and flow properties.

Available Filling Mechanism Options

The machine supports the following interchangeable or configurable filling systems. Selection depends on the material type, required packaging speed, and production volume.

1. Pneumatic Valve Port: Uses compressed air to fluidize fine powders into a quasi-liquid state for fast, dust-free filling. Ideal for lightweight, fine-particle materials like cement powder and dry mortar.
2. Ultrasonic Sealing Valve Port: Applies ultrasonic energy to create hermetic, airtight seals on valve bags. Prevents moisture ingress and contamination. Suitable for hygroscopic materials.
3. Impeller Type and Air Flotation Type: The impeller mechanism uses a rotating blade to push powder into the bag, while air flotation lifts and suspends the material for smooth flow. Both options work well for medium-density powders.
4. Spiral Valve: A screw-based internal valve system that controls and regulates powder flow with precision. Suitable for materials that tend to bridge or clump.
5. Screw Opening: Uses an auger screw to meter and discharge materials at a controlled rate. Preferred for dense or abrasive powders.
6. Gravity Valve Port: Relies on the natural downward flow of material through a gravity-fed valve. Cost-effective for free-flowing granular materials.
7. Gravity Opening: A simplified gravity drop system for materials with strong self-flow properties.
8. Belt Type Opening: Employs a belt conveyor-integrated opening system for smooth, continuous bag discharge.
9. Big Bag (Bulk Bag) Option: For operations requiring ton-bag or jumbo bag output, a large-format bulk bag filling configuration is also available.

Each filling mechanism is matched to specific material characteristics. Contact the sales team with your material specifications to receive the correct recommendation.

 

How the Machine Works: Operation Steps

The operation of the 25kg valve bag crack-resistant mortar packaging machine follows a defined automated sequence.

1. Material is fed from a storage hopper or silo into the machine’s feeding system.
2. The operator places a valve bag onto the filling spout. The machine detects bag placement automatically through a sensor or travel switch.
3. The selected filling mechanism (pneumatic, screw, gravity, or impeller) activates and begins discharging material into the bag.
4. The built-in microcomputer weighing system monitors fill weight in real time using precision load cells.
5. When the target weight (25kg) is reached, the discharge nozzle closes automatically, stopping material flow.
6. The bag pressing device activates, tilting the filled bag outward so it drops cleanly onto the discharge conveyor or collection area.
7. The system resets and is ready for the next bag cycle.

This sequence runs continuously without operator intervention between cycles, significantly reducing labor requirements and increasing output consistency.

Frequently Asked Questions

What types of bags does this machine support?

This machine is designed for valve-type bags in the 25kg weight range. Big bag (ton bag) configurations are also available.

Can one machine handle multiple materials?

Yes. The modular filling mechanism design allows the same machine to be reconfigured for different materials by switching between pneumatic, screw, gravity, or impeller-type filling heads depending on powder flow characteristics.

What is the weighing accuracy of the machine?

The machine uses a microcomputer-controlled load cell weighing system with high sensitivity. Actual tolerance specifications vary by model and configuration.

What is the difference between pneumatic valve, screw, and gravity filling?

Pneumatic filling uses compressed air to push fine powders rapidly into bags and is best for low-density materials. Screw filling uses an auger to meter denser materials precisely. Gravity filling relies on the material’s own weight and flow, making it a simpler option for free-flowing granules. The correct selection depends on your material’s bulk density and flowability.

Is after-sales support available?

Yes. A dedicated technical and after-sales service team provides professional support for installation, commissioning, and ongoing maintenance.
