Advantages of Belt Type Concrete Batching Plant

The core advantages of belt type concrete batching plants are their high aggregate conveying efficiency and adaptability to large production capacity demands. They can stably match mixers with a capacity of 120 m³/h and above, making them particularly suitable for continuous production on large-scale projects.

Their specific advantages can be analyzed from the perspectives of production, cost, and maintenance:

1. Production Efficiency: Suitable for large production capacity and strong continuous operation capabilities

– Large and Stable Conveyor Capacity:

Belt conveyors (especially wide belt models) can transport much more aggregate than screw conveyors (common in small concrete batching plants). A single belt can transport hundreds of tons of aggregate per hour, meeting the continuous feeding needs of large concrete mixers of JS2000 and above, avoiding “waiting for material” downtime due to insufficient feed.

– Excellent Gradeability:

The belt can be adjusted in angle (typically with a maximum inclination of 18°-25°) to transport aggregate over long distances and high drop heights, eliminating the need for additional transfer silos, streamlining the production process, and reducing material backlogs.

2. Operating Costs: Better Long-Term Economics

– Lower Energy Consumption:

Belt conveyors rely on frictional transmission. Compared to the “forced push” of screw conveyors, belt conveyors require less motor power for the same conveying capacity, resulting in long-term electricity cost savings of 15%-30%.

– Low Cost of Consumable Parts:

The core consumable part of a belt conveyor is the conveyor belt (with a normal service life of 1-2 years). Replacement costs are far lower than the blades of a screw conveyor (which are prone to wear and require replacement every 3-6 months). Maintenance does not require disassembly of the complex structure, resulting in lower labor costs.

3. Material Adaptability: Compatible with a Wide Range of Aggregates, Reducing Losses

– Compatible with a Wide Range of Aggregates:

Belt conveyors are more tolerant of aggregate particle size and moisture content, capable of stably conveying gravel and pebbles with a particle size of ≤80mm, and even slightly muddy and damp aggregates (those that are less likely to stick to the belt and prevent clogging). Screw conveyors, on the other hand, are prone to material jamming and blade wear due to damp aggregates and uneven particle sizes.

– Low Material Loss:

Belt conveyors offer an “open and gentle conveying” method. Compared to the “enclosed and squeezed” method of screw conveyors, aggregates are less likely to break during conveying, and material loss can be kept below 1%. This makes them particularly suitable for concrete production applications requiring high aggregate grading.

4. Maintenance and Flexibility: Simple Operation and Strong Site Adaptability

– High Maintenance Ease:

Belt conveyors have a simple structure, and key components (motor, rollers, and idlers) are easy to inspect and replace. Daily maintenance requires only regular cleaning of the belt surface and adjustment of the belt tension, eliminating the need for specialized technicians. Most belt conveyors are equipped with “deviation warning” and “slip protection” devices to reduce the risk of failure.

– Flexible Site Layout:

Belt conveyors can be designed to run in straight lines, curves (using corner rollers), or angled conveyors, adapting to the site’s shape. They can also be installed overhead or on the ground, saving floor space. They are particularly well-suited for the complex layouts of large-scale belt concrete batching plants with multiple machines and silos.

5. Environmental Protection:

– Easy to Install Dust Removal to Reduce Dust Pollution

Although the “open” design of belt conveyors may appear dusty, targeted modifications can be made to meet environmental standards:

A sealed cover and pulse dust collector can be installed above the belt to collect dust generated during aggregate conveying, keeping dust emission concentrations below 20mg/m³, meeting environmental standards.

Compared to screw conveyors, which are “enclosed but prone to dust leakage” (dust accumulation and leakage at bearings and joints), dust removal modifications for belt conveyors are simpler and more stable.

Belt type concrete batching plants are not suitable for all scenarios. Their advantages are most pronounced in large-scale projects (such as high-speed railways, bridges, and large real estate projects), with high production capacity requirements (≥120m³/h), and long-term continuous production. For smaller projects (capacity ≤60m³/h) or those with very limited space, spiral concrete batching plants may be more flexible.
