The DCS-BF1 Mixture Bagger is a belt feeding type, semi-automatic bagging machine designed to pack block materials, lump materials, granular materials, and granule-powder mixtures into bags ranging from 1 kg to 50 kg. It delivers a packing capacity of 180 to 250 bags per hour with a weighing precision of ±0.2% FS, making it a dependable choice for industries that handle irregular, mixed, or difficult-to-flow bulk materials.

What Is the DCS-BF1 Mixture Bagger?

The DCS-BF1 is a high-performance automatic weighing and bagging machine built around a belt feeding mechanism. Unlike gravity-fed or auger-type fillers, its belt conveying system transports even chunky, irregular, or mixed bulk materials smoothly and consistently. It is controlled by a high-performance double-speed motor paired with a material layer thickness regulator and pneumatic cut-off door, giving it precise control over both fast and fine-feed stages during each fill cycle.

This machine is purpose-built for materials that challenge conventional packaging equipment, including materials with poor fluidity, high moisture content, irregular shapes, or a mixture of coarse and fine particles. It bridges the gap between granule baggers and block material packers, handling both in a single machine without retooling.

Key Features of the DCS-BF1 Belt Feeding Mixture Bagger

1. Double-Speed Motor with Layer Thickness Regulator — The dual-speed motor controls material flow at two feed rates, fast feeding to reduce cycle time and slow feeding to improve final weighing accuracy. The layer thickness regulator ensures consistent material distribution across the conveyor belt, preventing uneven delivery that can cause weighing errors.
2. Touchscreen Control Interface — The machine uses a touchscreen control instrument for easy parameter setting and monitoring. Weighing sensors and pneumatic actuators work together with the controller to maintain stable, repeatable fill weights across every bag.
3. Automatic Error Correction and Fault Diagnosis — Built-in automatic error correction compensates for overshoot and undershoot in real time. Positive and negative difference alarms notify operators when fill weights drift outside acceptable tolerances. A fault source diagnosis system identifies and displays error codes, reducing downtime and simplifying maintenance.
4. Anti-Deviation Scraping Device — A scraping device positioned on the belt prevents material from deviating sideways and entering the inner belt section. This protects mechanical components and keeps mixed materials well-aligned during transport to the filling spout.
5. Dust-Proof Bag Clamping Mechanism — The bag clamp uses a seamless clamping structure designed to prevent material residue from accumulating at the bag mouth and to eliminate dust leakage during filling. There is no residual powder buildup in the clamping zone, which keeps the work area clean and reduces product loss.
6. Stainless Steel Construction — All material-contact components are made from stainless steel, which provides resistance to corrosion, moisture, and chemical contact. This extends service life and simplifies cleaning in environments where organic materials, fertilizers, minerals, or food-grade substances are handled.
7. Pneumatic Gate Control — Large and small discharge gates are controlled pneumatically, allowing precise adjustment of material flow rates at each stage of the fill cycle, resulting in tight, consistent bag weights.

How the DCS-BF1 Packing Process Works

The operating sequence of the DCS-BF1 follows a consistent, semi-automatic workflow:

1. The operator manually places an empty bag onto the bag clamping mechanism.
2. The machine automatically clamps and holds the bag at the filling spout.
3. Belt feeding begins at high speed to rapidly fill the majority of the target weight.
4. The system switches to low-speed feeding as it approaches the target weight, allowing precise final weighing.
5. The pneumatic cut-off door closes when the target weight is reached and the fill is complete.
6. The bag clamp releases and the filled bag is automatically transferred to the conveyor for sewing or heat sealing.

This automated sequence after manual bag placement reduces operator fatigue and produces consistent, accurately filled bags with minimal product variation.

Materials the DCS-BF1 Handles

The DCS-BF1 Mixture Bagger is specifically suited for bulk materials that resist smooth flow or that contain a combination of particle sizes and densities. Compatible materials include:

• Block and lump materials such as stones, bricks, rubber chunks, wax blocks, and briquettes
• Irregular granular materials including gravel, wet sand, rock salt, and mineral aggregates
• Organic materials such as compost, organic manure, farmyard manure, and wet biomass
• Agricultural inputs including granular fertilizers, mixed NPK pellets, seed coatings, and animal feed
• Industrial granules such as plastic pellets, chemical granules, and resin lumps
• Granule and powder mixtures where fine particles and coarse granules must be packed together without separation or bridging

This range of compatible materials makes the DCS-BF1 a versatile automatic weighing and bagging machine for agriculture, mining, chemical processing, food processing, and construction material industries.

Industries and Applications

The DCS-BF1 serves multiple sectors that require reliable, high-speed quantitative packaging of non-uniform materials:

• Agriculture and Horticulture: Organic fertilizer bagging, compost packaging, granular pesticide packing, and seed treatment materials
• Mining and Construction: Gravel bagging, sand packaging, mineral granule filling, and crushed stone packing
• Chemical Industry: Industrial salt packing, chemical granule bagging, and mixed resin packaging
• Food Processing: Coarse grain packaging, salt packing, sugar packing, and mixed feed bagging
• Biomass and Recycling: Wood chip bagging, charcoal block packing, and mixed biomass filling

Why Choose the DCS-BF1 Over Standard Bagging Machines?

Standard gravity-fall bagging machines and auger fillers are designed for fine, free-flowing powders or uniform pellets. They perform poorly with irregular shapes, large lump sizes, or wet materials that do not flow reliably. The DCS-BF1 solves this with its belt feeding design, which physically moves material rather than relying on gravity or forced airflow.

Key operational advantages include:

• Handles materials with poor fluidity without bridging or blockage at the feed point
• Consistent fill accuracy of ±0.2% FS even with mixed particle sizes
• Reduced labor cost through automated clamping, filling, weighing, and conveying
• Minimal product loss due to the sealed, dust-controlled bag clamping zone
• Compact, durable build requiring low maintenance effort over long operational periods
• Compatible with both woven polypropylene bags and open-mouth multiwall bags for flexible packaging options

DCS-BF Series Comparison at a Glance

The DCS-BF series includes three models to match different production scales:

• DCS-BF: Entry-level model, 150 to 200 bags per hour, suitable for small-scale operations
• DCS-BF1: Mid-range model, 180 to 250 bags per hour, balanced throughput and precision for medium-scale lines
• DCS-BF2: High-output model, 350 to 500 bags per hour, designed for large-scale industrial bagging lines requiring maximum throughput

All three models share the same ±0.2% FS precision standard and operate within the same weighing range and power supply specifications. The DCS-BF1 represents the optimal balance between speed, accuracy, power consumption, and machine footprint for most mid-volume industrial applications.

Conclusion

The DCS-BF1 Mixture Bagger is a reliable, accurate, and versatile belt-fed bagging machine built for industries that need to package block materials, lump materials, irregular granules, and mixed powder-granule combinations at commercial production speeds. With 180 to 250 bags per hour capacity, automatic error correction, touchscreen controls, pneumatic gate management, and stainless steel construction, it delivers consistent packaging performance across a wide range of challenging bulk materials. It reduces manual labor, controls product waste, and maintains tight fill tolerances across every shift.
