Conveyor belt for bulk material handling

Product Introduction

Conveyor belt for bulk material handling is a mechanical equipment that carries and transports granular or powdery materials through a continuous moving surface (such as rubber belt, plastic belt, metal mesh belt, etc.). Its core function is to use the friction between the conveyor belt and the material to transport the material from the feeding point to the unloading point to achieve efficient and continuous material transfer. Based on the principle of mechanical transmission, it is a continuous conveying equipment designed for discrete materials such as particles, powders, and small blocks. Its core function is to transport materials from the feeding end to the unloading end through the movement of the ring conveyor belt. It is suitable for large-scale material handling in industries such as mining, metallurgy, chemical industry, grain, and building materials.

What is the working principle of conveyor belt for bulk material handling?

Conveyor belt for bulk material handling system uses mechanical power to generate continuous movement of the belt, using friction to transport loose materials to a specified path. The design and specific components used are tailored to the characteristics and application requirements of the bulk materials being transported.

Bulk materials are fed to the conveyor belt at the loading point through a feeder.

The motor drives the head pulley to rotate, and the friction between the pulley surface and the bottom of the belt pulls the belt forward.

The load-bearing rollers along the length of the conveyor support the weight of the belt and the material, and the belt is usually shaped into a groove to maximize the material.

The continuous movement of the belt transports the bulk material from the loading point to the unloading point.

Characteristics of conveyor belt for bulk material handling

Specially for non-unitized materials: The core design of bulk material conveyor belts is to convey large quantities of loose materials without independent packaging, such as granular, powdered, and block materials, such as coal, ore, grain, sand, cement, chemical raw materials, etc.

Large conveying capacity and efficiency: Conveyor belts for bulk material handling are usually designed to be able to convey large quantities of materials at a high speed and in a continuous manner to achieve efficient material handling.

Diverse structures and forms: In order to prevent bulk materials from spilling during transportation, many bulk material conveyor belts will use special structures such as skirts and sidewalls, especially when conveying at an angle.

Material adaptability: It can convey granular materials ranging from 0.1mm to 300mm, including powdered, granular, block and paste materials. For high humidity (such as wet coal, wet sand) or sticky materials (such as flour, powdered sugar), special anti-stick coatings or pattern designs are used.

Recommended mesh count for conveyor belt for bulk material handling

The mesh count is an indicator to measure the particle size of the material, usually indicating the number of mesh holes per inch of length. The larger the mesh count, the smaller the particles.

Mesh size (mesh)	corresponding particle size (mm)	material form example
Below 10 mesh	>2 mm	coarse block, crushed stone
20~60 mesh	0.25~0.85 mm	sand, granular material
80~200 mesh	0.074~0.18 mm	flour, fly ash
Above 200 mesh	<0.074 mm	ultrafine powder, carbon black

Key description

Fine powder material: For example, fine powder above 200 mesh is easy to raise dust and adhere, and it may be necessary to choose a conveyor belt with a side guard, closed structure or special surface treatment to reduce losses and environmental pollution.

Medium granular material: For example, particles between 20 mesh and 200 mesh are the most commonly handled material range of conveyor belts, and various types of conveyor belts have applicable models.

Coarse block material: For example, block materials less than 20 mesh need to consider the strength and impact resistance of the conveyor belt and measures to prevent materials from rolling off.

Application of conveyor belt for bulk material handling

Bulk materials (such as granules, powders, and block materials) are widely used in many industries due to their non-fixed shape, diverse particle sizes (from high-mesh fine powder to low-mesh large blocks), fluidity differences, and abrasiveness.

Mining industry: For ore transportation (such as iron ore and copper ore) from the quarry to the crushing station and the beneficiation plant, a corrugated sidewall conveyor belt is used to achieve a 45°-90° large-angle climb and reduce infrastructure costs.

Port industry: For loading/unloading of grains such as soybeans and wheat, tubular conveyor belts reduce dust pollution and meet environmental protection requirements. The belt speed can reach 4.5m/s, which improves loading and unloading efficiency.

Building materials industry: For the transportation of limestone and clay from the raw material field to the crusher and preheater, heat-resistant conveyor belts are used to transport cement clinker, which extends the service life by 30%. The skirt + pattern design prevents sand and gravel from sliding.

Chemical industry: precise conveying of powder and granular materials, pre-packaging conveying of urea and compound fertilizer, and conveying of raw salt and industrial salt. Conductive rubber conveyor belts prevent static electricity accumulation of powder materials.

Agricultural industry: large-scale processing of grain and feed, and transportation of corn and wheat from grain depots to processing plants. Use food-grade conveyor belts for bulk material handling to transport grain and reduce the risk of cross-contamination.
