The Sidewinder series of crushers screen out material that is the right size before it reaches the crusher, which reduces wear and increases production. With a closed-circuit design and four-bar impactor, the crushers can produce up to four sizes of material: three uniformly sorted and one oversized. A flop gate within the pant leg chute can be used to either recirculate oversized material or divert it for stockpiling. Three sizes are in the series, each with a three-deck horizontal screen. Sidewinder 15, 20 and 30 can process 400, 600 and 750 tons per hour, respectively. Screening areas are 210, 288 and 360 square feet, respectively.
