Case Studies: Vibrating Screens or Separation Screens
View case studies and watch videos below about Separation Screens, also known as Vibrating Screens.
These types of screens can be used in a variety of industries. Fine mesh, ultra-durable urethane screens are used for wet screening and dewatering. Larger, brute force, heavy-duty and grizzly vibratory screens are used in the bulk processing of aggregate, wood chips, limestone, boiler ash and more. Finger Screens, or non-blinding separation screens, are used to sort, classify and convey waste material in single stream, multi-stream, scrap metal, asr and C&D recycling systems.
Vibratory Screening Machine to scalp or separate particles using vibration. Unit is driven by two brute force vibratory motors mounted on sides of the unit. Vibratory motors can be mounted on top or under the unit if required. Four each isolation springs allow for mounting of the unit. Wire mesh screen panel can be removed for maintenance or replacement. Material exiting the “overs” or end of screen panel are discharged to the side of the unit. Material passing through the screen panel or “unders” drops onto a hopper for discharge to the next stage of processing.
Included as an option is control system to start and stop the vibratory screen. Available in most sizes to provide the required square footage of screening area for most applications.

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.
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.
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.
A Mineral Sands Producer used a new fine screening machines (or repulp equipment) to recover Garnet at over 90% efficiency. The older, conventional vibrating screens were only able to recover material at about 44% efficiency.
