Producing API in-spec frac sand from your wash plant is now easier than ever before.

The expanded capacity per screen means:

  • Reduced size of supporting structures
  • Less flow dividers
  • Less pumps are needed to operate and maintain
  • Reduced capital costs and operating costs

Removing Oversized Waste from Dune Sand at West Texas Frac Sand PlantRemoving oversized waste from feed to the wet plant.

The sand (dune sand) deposits being mined for frac sand in the West Texas area commonly has oversize and undesirable objects contained in the feed to the wet plant. These objects can be 1/2” to 3/4” sized caliche or other small aggregate, as well as organic material like roots, leaves, and sticks. The objects are problematic for wash plants and cause contamination issues for the final frac sand products.

Vibrating finger screens provide consistently accurate sizing for Waste Wood Recycling.

First, raw Waste Wood material is fed into a variable speed vibrating feeder.  The feed rate is adjusted for product density.  The first vibrating finger screen removes oversized material, which is sent back for shredding.

Next, the material is sent through a fines removal trommel.  Then, it is sent through two finger screens for secondary screening.  Spreader feeders are used for improving material distribution across the width of the finger screens.

A US Lime producer needed to replace 2 brute force vibratory screens at their limestone quarry due to constant failure of the drive bearings, lost production time and maintenance costs. After discussions with plant engineering, a single unit with a natural frequency drive screen was selected to process crushed limestone at a rate of 650 tons per hour.
