What is chain conveyor?

Chain conveyors use an endless chain both to transmit power and to propel material through a trough, either pushed directly by the chain or by attachments to the chain. The chain runs over sprockets at either end of the trough. Chain conveyors are used to move material up to 90 metres (300 ft), and typically under 30 metres (98 ft).

The materials and specifications of the chain plates are all customized. For example, 304 stainless steel is selected for transporting food or high and low temperature resistance, and carbon steel is suitable for transporting relatively heavy materials without chemical reactions; there is also bottle washing. If the machine needs to drain the water, the perforated connecting plate is chosen as the bearing surface.

Types of Chain Conveyors

Chain conveyors are a type of mechanical conveyor system that uses chains to move materials along a predetermined path. There are several types of chain conveyors commonly used in various industries. Here are some of the most common types:

1.Slat Chain Conveyor: It use flat slats or plates linked together by chains to convey materials. They are often used for transporting hot, oily, or abrasive materials.

2.Drag Chain Conveyor: The chain is used to drag or move materials along the conveyor path. It is suitable for handling heavy or bulky materials.

3.Wire Mesh Chain Conveyor: It use a chain with a mesh or grid pattern to convey materials. They are suitable for applications where air or light needs to pass through the conveyor belt.

The following table shows you the differences between the above three types of chain conveyors:

Differences	Slat Chain Conveyor	Drag Chain Conveyor	Wire Mesh Chain Conveyor
Chain material	Steel plate chain	Steel or plastic drag chains	Metal mesh belt
Conveying materials	Heavy, regular-shaped materials	Heavy, irregularly shaped materials	Lightweight, irregularly shaped materials
Conveying environment	High temperature, high humidity, corrosive environment	Harsh environments, such as dust and oil	Environment with high requirements for cleanliness and hygiene
Application scenarios	Automobile manufacturing, metallurgy, mining and other industries	Material transportation, automated production lines	Food, medicine, electronics and other industries
Advantages and disadvantages	Strong load-bearing capacity, but poor flexibility	Highly adaptable, but easily worn	Hygienic and easy to clean, but limited carrying capacity

Application of Chain Conveyor

Chain conveyors are used in a variety of industries and applications for the handling and transportation of materials. Here are some examples:

Manufacturing: Transporting parts between workstations, assembly lines, and storage areas. They can be customized to suit different types of materials, including raw materials, finished products and heavy machinery.

Food Processing: Transporting food at all stages of production and packaging. They are designed to meet strict hygiene and safety standards and can be made from materials suitable for food contact.

Logistics: Used in logistics and distribution centers to move products between different stages of the supply chain. They can be used for truck loading, shipping packages and containers, and sorting delivered products.

Construction: Used on construction sites to move heavy materials such as concrete, steel and bricks. They are often used to transport materials to hard-to-reach areas and can be customized to fit different types of construction equipment.

Mining: Used in the mining industry to transport bulk materials such as coal, ore and aggregates. They can be designed to operate in harsh environments and can handle heavy loads over long distances.

Working Principle of Chain Conveyor

The working principle of a chain conveyor involves a chain that is driven by a motor and moves along a track or series of tracks. The chain is typically made of steel and is attached to a series of slats or plates that carry the material being transported. The slats or plates can be made of various materials depending on the application, such as plastic, wood, or metal.

When the motor is turned on, the chain begins to move along the track, pulling the slats or plates along with it. The material being transported is placed on top of the slats or plates and is carried along the conveyor as it moves.

Benefits of Chain Conveyor

Heavy handling

It is used to carry heavy objects and transport materials over long distances. The weight of a single material (piece) can reach 70-120kg, the conveying capacity can reach 60m/h, and the conveying distance can reach 90 meters.

Multifunction

Can be designed to suit various layouts and configurations, making it adaptable to different production environments

Low maintenance cost

Chain conveyors require relatively little maintenance compared to other types of conveyors. The chain is durable enough for long periods of continuous operation with minimal maintenance.

High-speed handling

Material can be moved at high speeds, ideal for time-critical applications. They are also able to process materials at different speeds, increasing production flexibility.

Improve security

They are equipped with safety guards that prevent workers from touching moving parts, reducing the risk of injury or accidents.

Reduce labor costs

Automation can be achieved, reducing the need for manual labor and increasing efficiency. This can save costs for companies that rely on manual labor for material handling.

What is the difference between chain conveyor and belt conveyor?

The main differences between chain conveyors and belt conveyors are:

Compared	Chain Conveyor	Belt Conveyors
Design	Consists of a series of chains attached to slats or plates to carry material along the conveyor.	Consists of a belt driven by a motor and moved along a track.
Load capacity	Designed to handle heavier loads than belt conveyors. Chain conveyors are often used in industrial settings to move heavy or bulky materials such as pallets, containers or products on an assembly line	Typically used in transportation and logistics to move lighter materials such as parcels and bulk products such as grain, fertilizers, cement, flour, etc.
Maintenance	Due to the higher number of moving parts, chain conveyors require more maintenance than belt conveyors	Fewer moving parts require less maintenance.
Cost	Typically more expensive than belt conveyors due to the greater amount of material required for their construction and higher load capacity.	Require less cost

Chain Conveyor Diagram

The chain conveyor uses the standard top plate chain as the bearing surface, driven by the motor reducer, and runs on the special guide rail. According to the different process, the chain conveyor is divided into turning type and straight type.

Material: carbon steel, stainless steel, chain plates of different widths and shapes can be selected according to actual needs to complete straight lines, turning, lifting and other requirements.

Customized Types of Chain Conveyor

The customized types of chain conveyors mainly include the following:

1. Heavy-duty chain conveyor: This type of conveyor is suitable for heavy-duty environments and can withstand large weights and pressures. For example, heavy-duty chain conveyors are often used in cleaning and drying equipment.

2. Large-angle chain conveyor: This conveyor has a large inclination angle and is suitable for scenes that require a large lifting height. For example, stainless steel chain conveyors are often used in the food processing industry to ensure food-grade hygiene standards.

3. Small chain conveyor: Suitable for occasions with limited space or requiring flexible layout. For example, small chain conveyors can be used in laboratories or small production lines.

4. Curved chain conveyor: Suitable for scenes that require curved conveying, and can adjust the conveying path according to needs. For example, curved conveyors are often used in loading and unloading scenes.
