Paste Backfill

Home IndustriesPaste Backfill

Consistent metering of difficult materials in paste backfill applications

Steele E Series Even Feeders have been dependable workhorses in paste backfill and mine tailings applications since 1993. These simple, durable machines provide consistent metering of wet, dry, sticky, abrasive, clumpy and slumping paste, filter cake and mine tailings, without the bridging and sticking that impede box and belt feeder operation.

Steele feeding solutions handle:

  • Coarse and fine mine tailings
  • Wet filter cake
  • Dried mine tailings
  • Mining sludge

Our live bottom feeders ensure consistent,
accurate metering for downstream machines.

Our work with plant engineers and mining operators has driven steady improvement in product and application design for feeding applications:

  • Material versatility — Steele even feeders take dense mine tailings, wet filter press cake, and dried, hard mine tailings, metering an even discharge of material into your downstream processes.
  • Application flexibility — We’ve sold 24 different feeder configurations for mine tailings and paste backfill solutions since 1993. We customize our E Series for almost all applications, using in-stock drive and wearing components on a proven, modular platform.
  • Maintenance-friendly — These machines are engineered for feeding difficult materials in harsh environments. Seals are designed for easy service with fast replacement of wear-resistant slipover spirals.

A paste backfill operation combines fresh dewatered mine tailings with dried tailings

Problem:

The customer had reclaimed gold mine tailings with approximately 18% moisture and needed a feeder to handle this difficult material with various particle sizes, metering them at a constant rate into a batch mixer in the plant.

Solution:

Steele provided two feeders for the application — one triple 124E and one double 124E. We outfitted the 124E with a large (120 cu. yd.) hopper filled with a loader. The two feeders work in tandem to deliver tailings to the batch mixer at an even rate, cycling on and off to the fill the mixer.

Result:

Like our even feeders installed at other mine tailing and paste backfill operations, these machines have proven to be reliable and low-maintenance. We estimate that these machines will process an estimated 50 million tons of bulk raw material over the course of their service lives.

We cast wearing parts in our in-house foundry and ship for fast replacement.

Service and parts to minimize downtime

We maintain a dedicated field service group for on-site maintenance and repairs in the continental U.S. Steele supports in-house maintenance operations with machinery repair and rebuilds in our Statesville, NC plant, with global service and strategic warehousing for customers around the world.
