Halbautomatische Trockenpulver-Verpackungsmaschine

A professional-grade semi-automatic packaging machine designed specifically for dry powder building materials, cement-based products, and industrial powders. Built for accuracy, durability, and adaptability across high-demand production environments, this machine series delivers consistent output for manufacturers in construction, food processing, pharmaceuticals, and chemical industries.

Whether you are packaging fine cement powder, metal powder, wood flour, or granular building materials, this equipment is engineered to match your exact production requirements with multiple filling mechanisms and configuration options.

What Is a Semi-Automatic Dry Powder Packaging Machine?

A semi-automatic packaging machine automates the core filling and weighing process while allowing operators to manage bag placement and sealing manually or with minimal intervention. This design balances high throughput with operational flexibility, making it ideal for mid-scale to high-scale manufacturing operations where product types change frequently or require custom filling configurations.

Unlike fully manual systems, semi-automatic powder bagging machines significantly reduce labor costs, minimize material waste, and improve packaging accuracy, achieving tolerances as tight as plus or minus one percent per fill cycle. Unlike fully automatic lines, they offer faster changeover times and lower initial investment, making them a preferred choice for growing manufacturing operations.

Product Range and Machine Types

This product line includes several specialized machines to accommodate different powder types, bag sizes, and production volumes:

1. Three-Head Packaging Machine: Designed for simultaneous multi-station filling, this machine maximizes throughput without sacrificing accuracy. It is commonly used in high-volume dry powder and building material production lines.
2. Automatic Weighing Packaging Machine: Integrates electronic weighing with PLC control for precise quantitative dosing. The system automatically detects and corrects weight deviations, ensuring consistent bag weights even when material density or flow properties vary.
3. Cement-Based Homogeneous Board Packaging Machine: Specifically developed for cement-based homogeneous boards and similar composite building materials. The filling mechanism is optimized for dense, abrasive powders that challenge standard equipment.
4. Dry Powder Building Materials Packaging Machine: A versatile bagger suitable for dry mortar, plaster, gypsum, concrete admixtures, tile adhesives, and other construction materials packaged in 10 kg to 50 kg valve bags or open-mouth bags.
5. 1000KG Automatic Metering Packaging Machine: A bulk bagging solution for large-volume applications. Ideal for operations handling significant daily output of cement, aggregates, or industrial powders.
6. 1000KG Electric Exposure Packaging Machine: Designed for materials requiring controlled discharge, this machine offers stable, consistent output in high-capacity environments.
7. 50KG Metal Powder Packaging Machine: Purpose-built for dense metal powders, featuring a robust frame and filling system designed to handle the unique flow characteristics and weight demands of metallic materials.
8. 18L Rolling Type Packaging Machine: Suitable for products packaged in drums or round containers, this rolling-type filler ensures efficient and clean filling without spillage.
9. 16KG Wood Flour Packaging Machine: Optimized for lightweight, fibrous, and low-density powder materials like wood flour, sawdust, or similar organic powders.

Valve Port and Filling Mechanism Options

One of the core strengths of this packaging machine series is the extensive range of interchangeable valve and filling mechanisms. Different powders require different discharge technologies to achieve accurate, clean, and efficient filling. Available options include:

• Pneumatic valve port: Uses compressed air to control powder flow. Ideal for fine powders that require controlled, dust-free filling.
• Ultrasonic sealing valve port: Applies ultrasonic energy to seal valve bags instantly upon filling, ensuring airtight closures for moisture-sensitive materials.
• Impeller type filling: Uses a rotating impeller to feed powder from the hopper into the bag. Well-suited for free-flowing powders with consistent particle size.
• Air floatation type: Aerates the powder before filling to improve flowability, particularly effective for fine or densely packed dry materials.
• Spiral valve (screw opening): A screw-driven mechanism that controls both the rate and volume of powder discharge with high precision.
• Screw opening: A simplified screw-feed system for medium-flow powders requiring steady, controlled output.
• Gravity valve port: Relies on gravity for powder discharge, best suited for dense, free-flowing materials that require minimal mechanical assistance.
• Gravity opening: Similar to the gravity valve port but configured for open-mouth bag formats rather than valve bags.
• Belt type opening: Uses a conveyor belt mechanism to support and position the bag opening during filling, providing a stable interface for various bag types.
• Big bag (FIBC) option: Supports bulk bag filling for operations that require jumbo bags of 500 kg to 1000 kg or more, commonly used in construction and agricultural supply chains.

Because different materials behave differently during filling, the correct mechanism selection is critical. Dense, abrasive powders like cement or metal powder perform best with spiral or pneumatic systems. Lightweight organic powders such as wood flour benefit from air floatation or impeller-type mechanisms. Consult the technical team to match your material properties with the optimal configuration.

Industries and Applications

This semi-automatic packaging equipment is widely deployed across multiple industries:

• Construction and building materials: Dry mortar, cement, tile adhesive, gypsum powder, homogeneous board materials, concrete admixtures
• Food industry: Flour, grain powder, starch, spice blends, milk powder, protein powder, nutritional supplements
• Pharmaceutical industry: Medicinal powders, chemical excipients, granular additives
• Chemical industry: Metal powder, wood flour, industrial pigments, detergent powder, carbon powder, talcum powder
• Agriculture: Fertilizer, pesticide powder, feed additives

Key Features and Technical Advantages

• High weighing accuracy with automatic error correction via electronic load cells
• PLC touchscreen control for easy parameter setting including fill weight, packaging speed, and counting
• Modular valve and filling head design allows fast changeover between product types
• Stainless steel hopper and contact parts for corrosion resistance and hygiene compliance
• Suitable for valve bags, open-mouth bags, bottles, cans, and big bags depending on configuration
• Compact footprint compatible with existing production line layouts
• Optional integration with conveyor belts, sealing machines, coding machines, and sewing systems
• Stable performance under continuous high-volume operation with minimal maintenance requirements

Why Choose This Packaging Equipment

This machinery series is backed by leading manufacturing technology and a commitment to after-sales technical support. Customers across food, pharmaceutical, construction, and chemical industries have trusted these machines for consistent output, reduced packaging waste, and lower total operating costs compared to manual bagging systems.

The configurable valve port system means a single machine platform can adapt to multiple products simply by swapping the filling mechanism, making it a long-term investment rather than a single-use asset. For operations scaling production volumes, the three-head configuration and 1000 kg bulk bagging variants provide a direct path to higher throughput without requiring entirely new equipment.
