Apron Feeder

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.

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.

MEKA 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.

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.

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 revolu¬tions. The sprockets are bolted onto keyed on hubs.

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.

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.
