Apron Feeder for Sale
The apron feeder, also called an apron feeder conveyor, is an important piece of conveying equipment in industrial production. It is suitable for conveying bulky, abrasive, heavy, and high-temperature materials. Apron feeder uses strong and durable overlapping metal panels. The chain drive ensures that the material can be delivered stably and evenly from the silo, hopper, or primary limestone crusher. This structure has stronger impact resistance and load-bearing capacity and is more stable than traditional belt feeder. It is widely used in industries such as lime, cement, mining, and quarrying. The maximum tilt angle of the apron feeder can reach 20°. It can operate reliably even under harsh conditions.
AGICO offers professional apron feeder solutions for lime production line, cement plants, power plants, metallurgy, and other industries. Customized solutions give customers more choices.
Advantages of Apron Feeder
Strong bearing capacity
The apron feeder conveyor uses high-strength material for the chain plates and chains. The impact resistance and load-bearing capacity are higher. It can withstand large, high-density materials.
Highly adaptable
The apron feeder conveyor can be adjusted incline to adapt to different terrains. It can also adapt to materials of different properties by replacing chain plates of different shapes and materials.
Economical and reliable
The apron feeder conveyor is rugged. It still has extremely high reliability under long-term and high-load operation. So it has a long service life and a low failure rate.
Uniform feeding
The apron feeder conveyor can be adjusted drive speed to adjust chain speed. It enables precise and uniform material feeding.
Important Parts of Apron Feeder
Chain Pan
Sprocket
Chain
Roller
- Chain Pan
The chain plate is the main conveying component that comes into direct contact with the material. It is usually made of high-strength material. These chain plates are connected by bolts and nuts, They overlap to form a continuous, moving conveying surface. The shape and thickness of the chain plate can be replaced according to the nature of the material.
- Sprocket
The chain wheel is usually forged or cast from high-strength alloy steel, the tooth shape meshes perfectly with the chain. And equipped with a hydraulic or screw tensioning device to adjust the chain tightness. The sprocket can be replaced section by section without disassembling other parts, which is convenient for local maintenance.
- Chain
The chain is the main traction and load-bearing component, it consists of a series of interconnected links. It has extremely high tensile strength and fatigue resistance. The chain moves in a circular motion driven by the driving sprocket, thereby driving the skirt plate attached to it forward to achieve continuous conveying of materials.
- Roller
The rollers mainly play the role of support and guidance. It is usually installed below the apron feeder rack. When the apron feeder starts working, the roller reduces the movement resistance by rolling itself. And prevent excessive friction and wear between the chain plate and the frame. So the quality of the scroll wheel is very important.
Working Principle of Apron Feeder
The material to be transported falls from the silo or hopper above the apron feeder onto the chain plate of the apron feeder. At this time, the drive device transmits power to the drive sprocket. The teeth of the drive sprocket mesh precisely with the links of the chain, driving the chain forward. Because the sprocket is fixed to the chain, the sprocket rotates with it. The materials carried on the chain are transported forward smoothly and evenly. The unloaded empty chain plate will return to the feeding end of the apron feeder along the return path below, forming a closed loop.
Apron Feeder VS Belt Feeder
—— In material conveying, apron feeder and belt feeder are both commonly used equipment, but they have significant differences in design, working principle, application scenarios and performance.
Apron Feeder
- Advantages: Strong impact resistance and load-bearing capacity. Suitable for harsh materials. High operational reliability. Uniform and stable feeding. Reduced wear on downstream equipment.
- Disadvantages: High initial investment cost. Large floor space. Heavy weight.
Belt Feeder
- Advantages: The initial investment cost is low. The conveying speed is fast. The energy consumption is relatively low. The maintenance is relatively simple and convenient. It is suitable for materials with fine particle size and good fluidity.
- Disadvantages: Weak impact resistance and load-bearing capacity. High environmental requirements. Limited belt life.
Industry Application Scenarios
1. Mining industry: Limestone, iron ore and coal mined from mines are all large pieces of raw ore. An apron feeder conveyor is needed to feed the jaw stone crusher or gyratory crusher evenly and steadily.
2. Metallurgical Industry: An apron feeder conveyor can transport blast furnace sintered ore and hot slag to the crushing or cooling system. Conveying heavy scrap metal in a scrap recycling plant.
3. Cement Industry: The heat and wear resistance of the Apron Feeder makes it an ideal choice for conveying hot, abrasive materials such as cement clinker or slag.
4. Port Terminal: At ports and docks, it is used to transport bulk cargo such as iron ore, coal, grain, etc. to storage yards or directly load them onto ships after unloading from ships, trains, or trucks.
Selection Guide
Material Characteristics
When choosing an apron feeder conveyor, material properties are the primary consideration. Choose the appropriate apron feeder conveyor based on the material’s maximum block size, abrasiveness, viscosity, material temperature, and density. Ensure that the apron feeder conveyor can adapt to these complex characteristics.
Production Capacity
Determine the rated handling capacity that the apron feeder conveyor must deliver per hour. Usually, a 25-35% margin is reserved to cope with instantaneous high loads and prevent overload. A drive system with variable frequency speed regulation can be selected.
Installation Conditions
Before installation, determine whether the apron feeder conveyor will be installed horizontally or tilted. Inclinations exceeding 20 degrees require the use of special chains. The temperature, humidity, dust level, etc. of the working environment should also be considered.
Suppliers and Experience
Choose a supplier with rich experience and a good reputation in the design, manufacture, installation, and commissioning of an apron feeder conveyor. For example, AGICO will provide professional selection recommendations, customized solutions, and reliable after-sales services.
