How does an apron feeder work?

How does an apron feeder work?

Apron Feeders work by conveying material from a hopper to the delivery point at a controlled rate of speed. The Apron Feeder consists of a frame, undercarriage components, head shaft, tail shaft, flights and a drive. The size of the opening combined with the speed of the flights provides a metered flow.

What is the purpose of apron feeder?

In simple terms, an apron feeder (also known as a pan feeder) is a mechanical type of feeder used in material handing operations to transfer (feed) material to other equipment or extract material (ore/rock) from storage stockpiles, bins or hoppers at a controlled rate of speed.

Which type of motor is used for apron feeder?

The two types of drives suited for variable speeds are a mechanical drive using a gear reducer, inverter duty motor and variable frequency drive (VFD), or hydraulic motor and power unit with a variable pump.

What is a feeder in mining?

Mining feeders for productive processing As an interface between mining trucks and the processing system, feeders provide steady, controlled feed for downstream processing – improving production and allowing for more predictable maintenance of processing equipment.

Why are apron conveyors sometimes called apron feeders?

An apron feeder is in fact a conveyor that is constructed from metal. It regulates the feed by carrying the ore to the delivery point at a controlled rate of speed.

What is reclaim feeder?

Reclaim feeders and feeder breakers are utilised to reclaim stockpiles and ROM material at a continuous feed rate. Trucks, front-end loaders, or dozers supply feeders with material, which then deliver the material in a consistent manner to a conveyor belt, sizer, or other process equipment.

What is a pan feeder?

Post navigation. The next feeder on the list is the PAN FEEDER, this one may also be called the reciprocating feeder and it works like this. The pan moves back under the ore picking up a load, it then slides forward carrying the ore with it. The pan is pushed forward then retracted.

What are the types of feeder?

Types of Feeders

  • Apron Feeders.
  • Belt Feeders.
  • Drag and Reclaim Feeders.
  • Reciprocating / Plate Feeders.
  • Scalper Feeders.
  • Wobbler Feeders.
  • Vibrating Pan Feeders.
  • Vibrating Grizzly Feeders.

What is a feeder conveyor?

The main difference between a feeder and a conveyor is that feeders are flood-loaded while conveyors are not. Also, while conveyors typically operate at a constant speed, feeders are always capable of varying the speed of operation.

What is a wobbler feeder?

Wobbler Feeders provide two functions in one unit: feeding material at a controlled rate, and scalping out the fines from the feed material. These feeders are especially good with wet, sticky materials where fines need to be scalped or are stuck to larger lumps.

What is a Buffalo feeder?

Contrary to the more traditional flight bar conveyor system used in most chain feeder designs, Buffalo feeders utilises the unique Buffalo flightless conveyor chain arrangement. This has many advantages, e.g. longer chain life, better size control and the capacity to run either or both the dual conveyor systems.

What can you do with an apron feeder?

Apron feeder machines can be found in mining operations, factories, and concrete plants. In mining, the apron feeder carries rocks and minerals for crushing or further processing. At a factory, these machines may be used to add ingredients to a food or other mixture.

Why are apron feeders made out of polyurethane?

Polyurethane seals in the chain prevent abrasive materials from entering the internal pin and bushing, which reduces wear and extends equipment life in comparison with a dry chain style. Tractor chain style apron feeders also create less noise pollution for quieter operation.

What makes Metso Outotec apron feeders so reliable?

With over 120 years experience in material feeding, Metso Outotec has developed a global standard in apron feeders. With our robust design, our apron feeders are a truly economic and reliable material handling solution for increasing uptime and overall efficiency.

Why are apron feeders run at variable speeds?

Apron feeders are designed to be ran at variable speeds to extract from storage and feed downstream at a controlled rate of speed for maximum efficiency. The material could vary depending on factors such as the season of the year, orebody, or blasting and blending patterns.
