Cold Mix Material Bag Filling Machine

A heavy-duty packaging system specifically designed to handle sticky, cohesive, and abrasive cold-mix asphalt materials. Unlike free-flowing materials, cold mix asphalt requires specialized feeding mechanisms to prevent clogging and to accurately pack the material into bags (typically 25 kg to 50 kg) for retail or road repair use.

Efficient, Accurate Cold Mix Packaging

An Asphalt Cold Mix Bag Filling Machine is a heavy-duty packaging system specifically designed to handle sticky, cohesive, and abrasive cold-mix asphalt materials. Unlike free-flowing materials, cold mix asphalt requires specialized feeding mechanisms to prevent clogging and to accurately pack the material into bags (typically 25 kg to 50 kg) for retail or road repair use.

Featuring a modular, corrosion-resistant design, the machine is built to handle abrasive materials with minimal wear. The user-friendly PLC control system allows quick changeovers between bag weights and material types, making it ideal for multi-product manufacturing facilities and project sites requiring flexible packaging solutions.

Anti-Sticking Feed Mechanism

Uses a heavy-duty screw feeder or a wide-throat vibratory tray rather than a gravity drop, preventing sticky, oily aggregate from bridging or clogging the feed hopper.

handshake

Pneumatic Bag Clamping

Heavy-duty, dust-tight bag holders grip the bag tightly during filling, ensuring no material spills and supporting the heavy weight of the aggregate.

memory

PLC + HMI Control

User-friendly touchscreen interface with recipe storage for different bag weights and material types.

build

Wear-Resistant Contact Parts

All parts in direct contact with abrasive asphalt (aggregate sizes up to 10mm–15mm) are made of reinforced carbon steel or heavy-grade SUS304/316 stainless steel to prevent premature wear.

settings

Adjustable Bag Conveyor & Sealer

Filled bags drop onto a motorized slat or heavy-duty belt conveyor, moving automatically toward a heavy-duty industrial sewing machine or heat sealer (depending on bag type).

What bag weights can this machine handle?expand_more

The standard machine handles 25 kg, 40 kg, and 50 kg bags. Custom ranges from 10 kg to 100 kg are available upon request.

What type of bags can be used?expand_more

The machine is compatible with heavy-duty PE/Plastic bags (best for long-term storage as they retain moisture/solvent oils) and laminated woven PP bags (highly durable for rough handling and transit, often paired with an inner plastic liner to prevent oil seepage).

How does the anti-sticking mechanism work?expand_more

The machine uses a heavy-duty screw feeder or a wide-throat vibratory tray rather than a gravity drop. This prevents the sticky, oily aggregate from bridging or clogging the feed hopper, ensuring consistent material flow.

Can the machine be integrated into an existing production line?expand_more

Yes, the machine is designed for easy integration with cold mix plants, conveyors, and material handling systems. Our engineers can customize the feed system to match your existing setup.
