About Screen Machine Industries

Screen Machine Industries has manufactured industry-leading crushing and screening equipment at its headquarters in Etna, Ohio since 1966.  SMI crushers and screeners are designed to increase durability and decrease downtime.  Two prime examples are the Smooth Start and the Remote Crusher Relief System. The Smooth Start controls the degree of shaking while the screening plant is warming up and shutting down, which reduces unnecessary wear and tear.  The Remote Crusher Relief System allows operators to clear blockage from the safety of their cab with a wireless remote.  Browse Company Wrench’s inventory of SMI equipment below.

Mobile Cone Crushers

 

SMI cone crushers feature a gyrating mantle that produces compressive force to process aggregate.  Cone crushers are frequently used as secondary crushers because they feature a smaller feed opening.  Features include:

  • Remote hydraulic adjustment of crusher to easily control the size of processed material
  • Patented Tramp Iron Relief System decreases downtime by discharging metal during the crushing process
  • 8:1 reduction ratio

Mobile Impact Crushers

SMI portable impact crushers use a rigid rotor with a small hammer to crush medium hardness materials, such as concrete, asphalt, and limestone, into a fine end product.  Features include:

  • Patented Remote Crusher Relief System for fast, safe remote clearance of material blockage
  • Adjustable cross-belt magnet separates metal contaminates from aggregate
  • 15:1 reduction ratio

  • Optional hammermill shredder easily screens finer materials from large clumps of dirt
  • Hydraulically foldable conveyor for easily transportation
  • Optional hopper extension for added screening capabilities

Mobile Screening Plants

SMI mobile track-mounted screening plants screens aggregate using vibration to separate the fine, mid-size, and oversized materials.  The properly sized aggregate passes through the screen into piles on the ground, while oversized material is filtered onto another conveyor leading to a separate pile.  Features include:

  • Triple deck shaker screen for accurate material sorting
  • Hydraulically foldable side walls for easy transportation
  • Units available with 2-4 conveyors for operations of any size
