The little knowledge you have to know about the apron feeders

Apron Feeders are famous of being a hard and credible choice for handling different materials. The little knowledge you have to know about the components of it, what they cost and how to size one for your application.
They are a fashionable material handling choice for many of applications, including aggregates, coal and other mining ore, and scrap/recycle material, because they deliver material at a constant uniform rate. They play an important role in helping sites meet their production goals by achieving maximum throughput and optimum uptime.
Apron Feeders are a mechanical type of feeder used for conveying material to a crusher or other piece of downstream equipment at a uniform rate. They are typically used to feed primary crushers, but they can be used in primary, secondary and tertiary applications.For it’s benefits, mainly are below:
1. It could handle extremely small and large capacities beyond the capacity of other types of feeders.
2.It could withstand extreme impact loading beyond the capability of other types of feeders.
3. It could provide the most accurate feed rate of all the feeders.
4. It could meter many types of wet or dry materials, such as mineral, aggregate and recycle, in a variety of sizes and shapes.
5.It have the longest service life with the lowest maintenance of all the types of feeders.
6.It could accept the material direct load, they often receive the dumped loads through the hopper. They can operate horizontally or inclinelly to save space or lessen the height requirements of the hopper.
7.It could with years between maintenance periods.
apron feeder mining
The components of the apron feeders were including:
1.Head shaft assembly - They are consists of chain drive sprockets bolted to a hub mounted to a head shaft. This assembly rotates to move the chain and flights forward.
2.Tail idler assembly - They are returns the chain and flights to the working surface of the feeder.
3.Chain - The chain wraps around the head shaft and tail idler and rides on carry rollers to provide movement.
4.Carry rollers -They are provide load carrying to the working side of the apron feeders.
5.Return rollers - They are support the chain/flight assembly on the return side.
6.Flights - Cast manganese steel flights or formed steel flights provide a wave surface to grip the material being conveyed.
7.Drive sprockets - They are intermesh the chain, moving it and the flights.
8.Impact rail - They are installed under the flights in the loading and strike-off area to prevent permanent deflection of the flights.
9.Main frame - They are provides a base for the operating components.
10.Drive -The mechanical and hydraulic drives are typically the two options for controlling.
10.Pull cord switch - Emergency stop pull cords and a zero-speed sensing switch stop the flow of material immediately.
11.Drag scraper (optional) - Drag scrapers capture fine wet material that may filter between the flights.
12.Dribble belt (optional) - Optional dribble belts capture fine dry material that may filter between the flights.
