Vibrating Screens

Wet frac sand tailings stream  is being processed to recover product before wet sand tailings are sent back to quarry. Water and silica sand is processed over a urethane screen panel designed to remove any remaining product from the tailings stream.

silica sand wet scalping screen

Three vibratory screens are being use to scalp oversized silica sand particles in wet screening application. Sand and water is being fed from a water separator onto the screen surface. All sand particles larger than 40 mesh are scalped off and removed from the flow.

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.

A Frac Sand Producer was looking to increase production rates at an existing production plant. The product specification goal was to produce a consistent 40 X 70 API (American Petroleum Institute) standard product.  Feed to the Stack Sizer screening machines is from a processed material stream that discharges from a hydrocyclone at a solid feed rate of 150 stph.
