How Apron Feeder Bulk Material Work?
apron feeder consists of drive wheel device, tail wheel tension device,pan- chain device and transmission device.
After the head sprocket is driven, the traction chain in the pan- chain device meshes with the sprocket to drive the entire pans to move along the longitudinal center-line and the roller travels along the track fixed on the frame, thereby completing work.
During the operation of Apron Feeder, the high-strength bulldozer die-forged chain is used as the traction part. On each link of the two rows of chains, the overlapping grooves of the heavy structure are assembled to form a continuous conveying line capable of carrying materials. The material discharged from the tail hopper is transported along the conveying line to the front of the body for continuous and uniform feeding.
Apron Feeder Bulk Material Details
Drive Device
Drive device utilizes an AC variable frequency drive system that integrates software with electronic and mechanical systems to provide precise conveyor speed control and overload protection.
The main components of the drive device can choose Siemens, ABB, Sew, Flender and other well-known domestic and foreign brands of motor and gearbox, to provide stable and continuous kinetic energy output, with high efficiency, low noise, low vibration and other characteristics.
Sprocket
Cast manganese segmental sprockets bolted to heavy steel hubs keyed to oversized front drive shaft.
The segmental sprockets can be replaced in a very short time without needing to dismantle or remove other parts of the feeder.
Pans
The pans bolted to the chain with high strength bolts and nuts, which can be replaced individually in situ without disturbing the rest of the apron feeder.
According to different working conditions, apron feeder can choose heavy duty cast manganese steel or welded construction with ribbed reinforcements, which is suited for materials with high load and high impact conditions.
Rollers
The rollers are designed as a standard tractor rollers with sealed and lifetime lubricated bearings, mounted on the main feeder frame. The rollers has suitably spaced to provide adequate support for the chain assembly.
The rollers can use world famous brands according to customer needs, such as Caterpillar, Komatsu, and Shantui.
Chains
The chain uses an off the shelf dozers chain (Track chain), which is characterized by small pitch error, smooth movement, high strength, large pulling force, and the chain has a self-lubricating device and a sealing device. The shaft is made of hardened steel, which improves the toughness and impact resistance of the traction chain, has good wear resistance and has a long service life.
Tail Tension Device
The tension device is used to tighten and adjust the horizontal position of the chain to ensure that the chain tightness is moderate and make it run smoothly. When the pans are suddenly impacted by the material, the composite spring can play a buffer role to protect the pans and other components from damage.
Apron Feeder Bulk Material Features
Strong Load Adaptation
Our apron feeder is specifically designed for bulk materials with a density of ≤ 2.0t/m³. It can efficiently handle large pieces of raw coal and ores up to 1500mm in size, and can easily meet the heavy-load transportation requirements of the mining and construction industries.
Flexible Installation Options
Our apron feeder supports horizontal installation and maximum 16° inclined installation. It can be flexibly adjusted according to the site layout and transportation path, suitable for various scenarios such as below the storage bin, feed inlet of the crushing station, etc.
Precise And Controllable Feeding
Our apron feeder is equipped with explosion-proof three-phase variable frequency motors. The feeding speed can be adjusted from 0.026 to 0.26m/s, and the production capacity covers 200-1500t/h, ensuring uniform and stable feeding and matching the processing rhythm of downstream equipment.
Robust And Durable Structure
The frame of our apron feeder is made of high-quality steel and welded. The I-beam structure is combined with multiple reinforcing plates, and after stress removal treatment, the strength and rigidity are sufficient to withstand the long-term impact of materials.
Wear-resistant And Impact-resistant Pans
The conveying pans of our apron feeder are of single circular arc joint type. They are made by welding low-alloy steel plates and are resistant to impact and do not leak materials. Combined with the special crawler chain for bulldozers, the service life is significantly extended.
Self-lubricating And Sealed Chains
Our apron feeder 's traction chains are equipped with self-lubrication devices and sealing structures, which can prevent abrasive materials from entering the internal parts, reduce friction loss, and increase the service life by 20-30%.
