Apron Feeders

Custom Designed For Any Application

AGGRETEK Apron Feeders are made of rugged, heavy duty construction and designed to handle large lumps and where no fines removal is required or where fines are removed by a separate Scalper. When the feed material is wet, sticky or clay like, the Apron Feeder is the machine to select. Generally, the Apron Feeder can be installed in a horizontal or inclined position. The high inclination also allows to build compact installations and to reduce the length of the Apron Feeder keeping the investment costs low.

Features

Optional Dribble Conveyor

As an optional extra, MEKA Apron Feeders can incorporate a Dribble Conveyor which is located under the feeder to catch the small pieces, fines and lumps of material that became trapped on the feed side of the apron pans and dribble out on the return side.
This feature eliminates manual clean up and saves on man hours.

Rugged Heavy Duty Construction

An Apron Feeder is run at very low speeds and at a controlled feed rate as it absorbs the impact loads of the material falling from a dump truck or a front-end loader and is ideal for withdrawing material from under a stockpile or from under a Primary Crusher.

Low Maintenance

MEKA’s heavy duty and robust apron feeders are engineered and built with an intense commitment to quality and attention to detail, providing maximum uptime and many years of service life.
Because of their durable, longlife components,
our apron feeders are low maintenance even under severe conditions.

Why AGGRETEK Apron Feeders

Our Apron Feeders are made of rugged, heavy duty construction and designed to handle large feed sizes and where no fines removal is required or where fines are removed by a separate Grizzly Scalper.

FRAME
Rugged welded construction frame to provide rigid support for intense loading conditions. Full length beams manufactured from rolled steel joists form the top and bottom members of this one piece unit. Crossmembers tie the framework together for maximum strength. Bolted onto these crossmembers are the universal beams which carry the impact rails and the carrier rolls. For ease of removing the carrier rolls, the outside carrier roll channels are sectionalized and bolted to the cross beams.

CHAIN
Crawler tractor type track chains, sealed and lifetime lubricated, are used on all MEKA Apron Feeders. The pins and bushes are all made from heat treated alloy steel and hardened on the wearing surfaces. The chain links are drop forged for increased carrying capacity and strength. The chains can be adjusted by means of a threaded screwed take-up arrangement. Hydraulic ram adjustment is available as an option.

INSTALLATION
AGGRETEK Apron Feeders are installed in horizontal as well as in inclined applications. Due to the special design of the aprons an inclination range up to 15° can be realized. In addition the bed height of the conveyed material stays constant ensuring an equal material flow to the further process. The high inclination also allows to built compact installations and to reduce the length of the Apron Feeder keeping the investment costs low. ease of removing the carrier rolls, the outside carrier roll channels are sectionalized and bolted to the cross beams.

HEAD DRIVE SHAFT
This heavy duty shaft is machined from high grade hot rolled steel.

CARRYING ROLLERS
The carrying rollers are standard tractor type featuring a hardened and ground shaft fitted with a centre thrust shoulder and hardened roller. The sleeve bearings on the carrying roller takes high impact loads and, with the duo-clone seals providing lifetime lubrication an extended wear life can be assured. Closely spaced along the length of the Feeder, smooth travel of deck during operation is maintained.

HEAD DRIVE SHAFT
The sprockets are of the bolt on segmental type made from wear resisting alloy steel. They are designed with an odd number of teeth which increases the life of the sprocket because contact with the teeth is only completed after two revolutions. The sprockets are bolted onto keyed on hubs.

BEARINGS
Anti-friction spherical roller bearings are fitted to the head and tail shafts and housed in heavy duty plummer blocks. Bearings are grease lubricated and a grease reservoir is included in the design of the bearing housings and end caps. The Apron Feeder has a remote mounted electrically operated automatic greasing system as standard.

TAIL TRACTION WHEELS
Cast steel traction wheels are lighter duty as they act purely as a directional guide to centralise the track. Long service life can be expected as there is minimal load carried on the traction wheels. as a directional guide to centralise the track.
