McLanahan Apron Feeders

McLanahan Apron Feeders

McLanahan Apron Feeders are a robust style of feeder that convey material from a hopper to the delivery point at a controlled rate of speed. Apron feeders excel at handling material that is beyond the scope of other feeders. They are generally used as a primary or bin feeder for varying applications – from light-duty to severe-duty and from low-tonnage to high-tonnage material. Apron feeders are available in six chain sizes, all designed to meet your application requirements.

Description

McLanahan Apron Feeders work by conveying material from a hopper to the delivery point at a controlled rate of speed. They consist of a frame, undercarriage components, head shaft, tail shaft, flights and a drive. The undercarriage chain wraps around the head shaft and tail idler, and flights are bolted to the strands of chain. The chain and flight combination rides on undercarriage rollers.

An apron feeder is usually installed under the opening at the discharge end of a hopper. As the head shaft rotates, the material in the hopper is pulled out of the opening by the movement of the flights. The size of the opening combined with the speed of the flights provides a metered flow. McLanahan Apron Feeders are tailored to fit many applications and installation requirements. This means that various aspects of the material stream, such as depth, can be adjusted to meet the required flow of material.

Features & Benefits

  • Rugged welded steel beam frame with impact rails to limit flight deflection, thus eliminating permanent bending of the flight
  • Large anti-friction spherical bearings on the head shaft, resulting in long bearing life
  • Grease lubricated bearings mounted in housings and labyrinth or taconite seals
  • Tractor idler wheels (sealed for life) are mounted to adjustable tail frame weldment
  • Standard undercarriage components, yielding a reliable, long-life feeder
  • Cast manganese segmental sprockets bolted to heavy steel hubs keyed to oversized front drive shaft
  • Superior flight sealing overlap design, reducing the leakage of fines
  • Dry chemical fire suppression
