Pit & Quarry, February 2017
SCREENING says David Hildebrandt Hikon Industries president Theyre often less expensive to purchase but rarely fine tuned to an individual pit The customization we do to match each application is important to achieve the highest levels of productivity and profitability Hikon custom built the chassis around the 6 ft x 20 ft three deck F Class screen Haver Boecker engineers factored in the desired tonnage and the material that Lonesome Prairie processes to determine what the machines Big Boy Quarry is one of five quarries owned by Lonesome Prairie The 100 ft deep pit sharply contrasts with others in the region that average 10 to 30 ft depths stroke should be the speed and general mounting guidelines Hikon took feedback from the aggregate company including adding a specially sized jaw crusher on the chassis Lonesome Prairie also asked that the bottom deck of the vibrating screen be end tensioned In the companys operation the design results in longer lasting screen media and 30 percent more productivity than side tensioned machines Haver Boecker customized the machine for Lonesome Prairies specific needs When the engineering design was in place both manufacturers got to work CUTTING TIME AND COSTS The finished system was inclined rather than horizontal like many portable systems allowing for a higher production capacity The machine included a hydraulic system to lift and position the vibrating screen at the optimal angle The F Class utilizes a base frame that attaches to the chassis Crews use the hydraulic system to set up the portable vibrating screen in less than 30 minutes with the entire plant including conveyors and other peripheral equipment People dont believe us when we tell them our costs are so far down and were getting more productivity HENRY DERKSEN LONESOME PRAIRIE SAND GRAVEL 44 PIT QUARRY February 2017 pitandquarry com
