What is a bulk granular material belt conveyor?

Bulk granular material belt conveyor is a belt conveying equipment for continuous transportation of granular and loose materials (such as sand, grain, coal powder, plastic particles, etc.). Because bulk granular materials have fluidity and accumulation, and different characteristics such as particle size, density, and humidity, this conveyor can effectively prevent particles from scattering through structures such as grooved rollers, and adapt to materials with different characteristics.

When working, the drive device drives the transmission roller, and the conveyor belt runs by friction to transport bulk granular materials from one end to the other. The roller support and tensioning device ensure stable operation. The conveying capacity is strong, and the speed can be adjusted according to the demand to achieve continuous and efficient conveying of a large number of granular bulk granular materials, and can be conveyed horizontally and inclined.

Bulk granular materials suitable for belt conveyors

Bulk granular material belt conveyors are suitable for dry bulk granular materials with a particle size generally between 1mm and 100mm, no obvious adhesion, and easy to flow. For materials with strong viscosity, high humidity, easy to agglomerate or easy to volatilize, it is recommended to use anti-sticking belts, covering covers, etc.

Ore and minerals: such as coal, iron ore, copper ore, limestone, sand and gravel, etc., the particle size is usually from a few millimeters to tens of millimeters, suitable for mining and building materials industries.

Chemical raw materials: such as fertilizers, ammonium sulfate, urea, plastic particles, etc., the particles are small and have good fluidity, and moisture-proof agents are required.

Grain and agricultural products: such as wheat, corn, soybeans, rice, etc., the particle size is uniform, and crushing and pollution need to be avoided.

Building materials: such as cement, fly ash, sand, gravel, etc., some of which are powdery or fine particles, easy to raise dust, and sealed pipes are required.

Industrial by-products: irregular granular materials such as slag, coal ash, and tailings.

What are the advantages of belt conveyors for bulk granular materials?

Belt conveyors have significant advantages in conveying bulk granular materials. In terms of efficiency, they can achieve continuous and uninterrupted conveying. Compared with intermittent transport equipment, they can greatly increase the material transfer speed and meet the rapid feeding needs of large-scale production. For example, the efficiency of coal transfer at ports can be increased by more than 50%. In terms of cost control, bulk granular material belt conveyors have low energy consumption and simple maintenance. The operating cost is much lower than that of loaders and other equipment. 

In addition, the conveying distance is long, which reduces the intermediate transfer links and further saves expenses. In terms of stability and safety, bulk granular material belt conveyor can smoothly convey materials and reduce the loss of granular materials due to bumps and spills. The closed or semi-closed design can also effectively prevent materials from flying and reduce the risk of dust pollution. In addition, the belt conveyor has flexible layout and can adjust the conveying route according to the terrain of the site. Climbing and turning can be achieved, which is perfectly adapted to complex working conditions.

Technical parameter table of belt conveyor for bulk materials (general reference)

The following is a typical technical parameter table of bulk material belt conveyors, which are suitable for conveying granular and fluid materials such as grain, sand, coal, feed, and fertilizer. This type of conveyor can be classified by belt width, and the commonly used standard is B400~B1600.

Model (bandwidth)	Belt width (mm)	Conveyor capacity (t/h)	Belt speed (m/s)	Conveyor length range (m)	Motor power (kW)	Applicable materials

B800	800	80～300	1.0～3.15	10～100	5.5～22	Building material aggregate, coal, chemical granules
B1000	1000	150～500	1.25～3.15	15～150	7.5～37	Ore, fertilizer, bulk materials
B1200	1200	200～700	1.25～3.15	20～200	11～55	Coal mine, port loading and unloading
B1400	1400	300～1000+	1.25～3.5	30～300	15～75	Bulk materials, shipping loading and unloading, coal terminal

Application of belt conveyors in the field of bulk granular materials

Belt conveyors play an important role in the field of bulk granular materials, and their continuous conveying capacity makes them the first choice for many industries.

Because bulk granular materials such as coal, iron ore, sand and gravel have irregular shapes, easy accumulation, and different fluidity, bulk granular material belt conveyors can effectively carry and smoothly transport these materials through their wide and flexible conveyor belts, minimizing leakage and dust.

In mines, it transports raw coal and ore from the mining face to the beneficiation plant; in ports, it can quickly and efficiently load and unload bulk grains and ore to ships or warehouses; in thermal power plants, bulk granular material belt conveyors are responsible for transporting coal from the yard to the boiler; and in the building materials industry, it is used to transport cement, gravel and sand to achieve continuous feeding on the production line.

Bulk granular material processing equipment: What is a bulk granular material production line?

Bulk granular material production line refers to a set of fully automated or semi-automated systems that process granular and bulk granular materials (such as ore, coal, sand and gravel, cement, fertilizer, grain, etc.) from raw materials into finished products, or perform specific processing and packaging. Bulk granular material belt conveyor is not just a collection of single equipment, but a combination of a series of interrelated and collaborative equipment and process steps. 

The core features are large processing capacity, high degree of automation, continuous process, and safe and stable operation. Common configurations include: feeding equipment (such as vibrating feeder), conveying equipment (such as belt conveyor, screw conveyor), screening equipment (such as vibrating screen), crushing equipment, mixing equipment, storage device, dust removal system and packaging system. In different application scenarios, the production line can be used for grading screening, quantitative mixing, drying and cooling, transfer and loading of granular materials. Through the centralized control system, collaborative operation and data feedback of each link can be realized, greatly improving production efficiency and material utilization.
