Bulk material handling is a critical component of many industries, from mining and agriculture to manufacturing and shipping. Among the various technologies used, conveyors play a pivotal role in ensuring efficiency and reliability in the movement of materials. bulk material handling involves the transport, storage, and control of loose materials such as minerals, grains, or powders. Industries such as cement, steel, food processing, and power generation heavily rely on these systems.

What Are bulk material conveyors?

Conveyors are mechanical systems used to transport bulk materials from one location to another. They offer a streamlined solution for moving materials efficiently, safely, and cost-effectively.

Types of Conveyors in Bulk Handling

1. Belt Conveyors

Belt conveyors are the most common type used for bulk material handling. A continuous loop of material (usually rubber or fabric) moves materials along a flat or inclined surface. These systems are ideal for handling granules, ores, and aggregates.

Key Applications: Mining, quarrying, Cement, Power plants, and more.
Features: Simple design, cost-effective, can handle a wide variety of materials like coal, aggregates, sand, and more.
Types: Flat belt, inclined, trough belt, overland conveyor and pipe belt conveyors.

This is a radial telescopic stacker conveyor for bulk material handling.

3. Radial Stackers

SKE Industries is a portable stacker conveyors manufacturer in China and has more than 13 years of experience in the development and production. You can get movable stacking conveyors for dry bulk material handling applications from us.

Application: Our radial stacker and radial telescopic stacker is primarily used for stockpiling materials like coal, ores, aggregates, and grains.
Features: Can pivot to distribute materials in a wide arc for uniform stacking, often used for stockpile management.

4. Screw Conveyors

Screw conveyors use a rotating helical screw blade within a tube to move granular or semi-solid materials. They are perfect for handling powders, grains, and other flowable materials.

Advantages: enclosed transport for handles dusty or hazardous materials.
Features: Can handle both horizontal and inclined material transportation, typically used in smaller or tight spaces.

material surface feeder for bulk material handling
This is a material surface feeder integrated with a chain belt conveyor for bulk material handling.

5. Chain Conveyors

Chain conveyors employ a continuous chain for moving loads. They are especially suitable for heavy materials and high-temperature environments.

Industries: Automotive, Recycling (slag, clinker, or scrap metal), and more.
Features: Uses a series of chains and flights to move heavy bulk materials.

6. Pneumatic Conveyors

Pneumatic conveyors use air pressure to move materials through pipelines. These systems are widely used for delicate or lightweight materials such as grains or powders.

Application: Used for fragile and lightweight materials such as paper or plastic.
Features: Uses a cushion of air to transport the material, reducing wear and tear on the material being conveyed.
Types: Vacuum conveyors and Pressure conveyors

7. Vibratory Conveyors

These conveyors use vibration to move materials. They are highly effective for materials requiring precise feeding and are common in food and pharmaceutical industries.

Application: Used for feeding, conveying, or separating materials that need to be handled gently or for precise material flow control.
Features: Uses vibrations to move materials across a trough, often used for bulk handling of small, granular materials.

8. Drag Chain Conveyors

Designed for moving bulk materials horizontally or vertically, drag chain conveyors use chains to pull materials along a trough.

Application: Used in applications where materials are to be transported in a controlled manner through an enclosed system.
Features: Drag chains pull materials along a trough, typically used for handling materials such as ash, grain, or powdered substances.
Benefits: Gentle material handling and Suitable for abrasive materials.

These are two grain bucket elevator conveyors.

9. Bucket Elevators

Bucket elevators are vertical conveyors that move materials using a series of buckets attached to a belt or chain.

Application: Used for vertically transporting materials like grains, coal, minerals, etc.
Features: Consists of a series of buckets attached to a belt or chain, designed to carry bulk materials to elevated heights.

Each type of conveyor has its specific application, advantages, and limitations, making it essential to choose the right one based on factors like material characteristics, distance, incline, and the environment in which it operates.

FAQs About Conveyors in Bulk Material Handling
