What is 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.

How does an apron feeder work?

How Apron Feeders 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.

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 are the types of feeders?

Types of Feeders

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

Which type of motor is used for apron feeder application?

Drive – Electro-mechanical and hydraulic drives are typically the two options for controlling Apron Feeders.

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 the difference between volumetric and gravimetric feeders?

A gravimetric feeder, also know as a loss-in-weight feeder, is a self-calibrating dosing system that doses based on weight in speed. A volumetric feeder, on the other hand, does this based on volume in speed.

How does a screw feeder work?

When screw conveyor works, the screw shaft rotates, and the material moves forward along the trough bottom of the conveyor under the push of the blade. Because of the gravity of the material and the friction between the material and the groove wall, the material does not rotate with the blade of the screw conveyor.

What are the 4 types of feeders?

Terms in this set (4)

• filter feeders. sift small organisms or food particles from water.
• bulk feeders. ingest large pieces of food.
• fluid feeders. suck nutrient-rich fluids from a living host.
• substrate feeders. live in or on their food source and eat their way through it.

What are the three types of feeders?

Feeder Types

• Ground. Many species of birds, including sparrows and doves, prefer to feed on large, flat surfaces and may not visit any type of elevated feeder.
• Large Hopper.
• Large Tube Feeder.
• Nectar Feeder.
• Platform.
• Small Hopper.
• Small Tube Feeder.
• Suet Cage.

What is chain feeder?

This feeder uses a series of very large, heavy chain that has been forged into loops. These loops are placed over cogged wheels that are suspended over the ore passage. The free end of the chain loops are hung down onto the rock. The size and the weight of the chain links are sufficient to stop the flow of ore.

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 are the best practices for the installation of apron feeders?

Rear access is suggested to have an additional 1,500mm at the tail end of the feeder for pans (flights) removal and installation. Additional best practices include installing a lift beam and trolley assembly above the drive system and across the back end of the apron feeder for removal of the pans (flights).

What is apron feeder drive?

Apron Feeder drive systems can be supplied in electrical-mechanical or hydraulic to match the duty and requirements of the application. Apron Feeders work by conveying material from a hopper to the delivery point at a controlled rate of speed.

Do I need to lubricate my apron feeder?

The only locations on the “tractor chain” style apron feeder that require any lubrication are the two pillow block bearings located on the head shaft. These bearings only require semi-regular grease lubrication.

What are the different types of loads in apron feeding?

First, there are three types of loads: Dead load, live load operating, and live load start up. Every application’s results will cause different degrees of value for each load type. Dead loads correspond to the self-weight of the apron feeder and any other hardware such as skirts, hoppers and chutes that may tie into the feeder frame.
