In industrial production, belt conveyors can be used as the link between production machinery and equipment to form continuous production, so as to realize the continuity and automation of production links, improve productivity and reduce labor intensity.
The belt conveyor can be widely used in mining, metallurgy, coal, transportation, hydropower, and other departments to transport bulk materials or finished items.

Aggregate belt conveyor is a continuous conveying equipment widely used in industries such as mining, building materials, and concrete mixing plants. It is mainly used to efficiently and stably transport bulk materials such as sand, gravel, and aggregates. They have the characteristics of large conveying capacity, stable operation, and convenient maintenance. They are one of the key equipment in modern sand and gravel aggregate production lines.
• Efficient and continuous conveying: It can operate 24 hours a day and is suitable for large-scale sand and gravel aggregate transportation.
• Strong adaptability: It can convey sand, gravel, machine-made sand and other materials with different particle sizes (0-300mm) and humidity (≤15%).
• Stable structure: It adopts high-strength conveyor belts and wear-resistant rollers to adapt to harsh working conditions such as mines and mixing plants.
• Flexible configuration: It can be arranged horizontally, tilted (≤30°) or in combination to meet the needs of different sites.
• Environmental protection and energy saving: The closed design reduces dust spillage, and the frequency conversion control reduces energy consumption.

1. Sand and gravel aggregate production line: connect jaw crusher, cone crusher, vibrating screen and other equipment to form an automated production line.
2. Concrete mixing station: transport sand and gravel to the mixing host, and accurately feed with the metering system.
3. Port terminal: used for loading or unloading, and long-distance transportation to the yard.
4. Mining: transport ore, tailings, etc., adapt to large slopes or complex terrain.
1. Small-scale production: choose a fixed belt conveyor (such as DT75) with a bandwidth of 650-800mm.
2. Long-distance transportation: consider steel cord belts (such as ST series) to increase the driving power.
3. High environmental protection requirements: closed design, equipped with dust removal and noise reduction devices
Aggregate belt conveyors and sand and gravel conveyors are core equipment in the sand and gravel industry. When selecting, it is necessary to focus on parameters such as wear resistance, conveying capacity, and inclination adaptability, and customize solutions based on working conditions.
Belt conveyor is used to transferring stone aggregates and sand in mining, quarry, chemical industry, aggregate production, construction material recycling, powder grinding plant, ball mill plant, etc.
A looped belt serves as both traction and carrier. The motor drives the drive drum through a reducer; drum–belt friction pulls the belt forward continuously. Maintained under tension by the tensioner, the belt loops around the drive and return drums, with idlers supporting it along the run to prevent sagging and misalignment.
Stone drops from the loading chute onto the carrying side, where troughed idlers cradle the belt into a trough that keeps the material centered and prevents spillage. The stone rides on the belt by friction, and discharges at the head drum by inertia and gravity, while the belt returns around the tail drum—repeating the cycle for continuous, high-volume conveying at low incline.

A stone belt conveyor uses a looped belt as both traction and carrier. A motor drives the drum through a reducer, and drum–belt friction pulls the belt forward continuously. Stone is loaded onto the carrying side through a chute, troughed idlers cradle the belt into a trough to keep material centered, and the material discharges at the head drum by inertia and gravity while the belt returns for another cycle.
For ordinary flat belt conveyors, the practical incline is usually limited to about 16°–18°, because rounded stone tends to roll or slide backward on the belt. Steeper angles require a deep trough belt, sidewall belt, cleated belt, or corrugated edge design to prevent material rollback.
They are widely used in quarries, sand and gravel plants, crushing and screening stations, cement plants, mining operations, concrete batching plants, and aggregate stockpiles—basically anywhere crushed stone, sand, ore or other bulk materials need continuous, high-volume transport between equipment or silos.
Yes. Belt width, belt speed, idler trough angle, overall length, incline angle and drive power are selected based on material size, lump weight, throughput (t/h) and site layout. Wear-resistant cover rubber and impact idlers are recommended at the loading point to handle the shock and abrasion of falling stone.
Routine checks include belt tension and tracking, drum and pulley lagging, idler rotation, belt cleaning by scrapers, and lagging wear. Key wear parts are the belt cover rubber, idlers, cleaning blades and drum lagging. Keeping the belt properly tensioned and centered prevents slip, spillage and edge damage, and extends belt life significantly.
