www.rockproducts.com ROCK products • June 2018 • 27 CRUSHING www.kpijci.com Conn-Weld Conn-Weld screens are designed per application for severe-duty separation. Features include: •  Designed for large particle separation. • Designed for large tonnage. • Designed for extremely large top size. •  Heavy-duty modular designed deck support frame for large particle feed. •  Mechanism with outboard counter- weights allow for adjustable stroke. • Oil lubrication. •  Oil reservoirs assure constant bearing lubrication. • Two part epoxy paint. • Cardan drive shaft. • Overload springs for surge loads. www.conn-weld.com Deister Machine Co. Deister offers its Model HSM and BHSM double-deck screens, with widths: 3- to 6-ft., and lengths: 6- to 18-ft. The double-deck HSM has the vibrat- ing mechanism located between the decks. All HS series models utilize proper depth of material bed manage- ment in combination with high g-force operation resulting in optimum separa- tion of fine materials. Steeper inclination (typically 30 degrees) results in a faster rate of par- ticle travel, therefore reducing depth of bed of heavy feed rates. The reduced depth of bed allows the finer particles to work their way toward the openings for sizing. Higher-than-conventional operating speed combined with sizable ampli- tude of vibration translate into higher g-forces that quickly stratify the material bed so that effective screening can begin. The high g-forces resist the accumula- tion of damp fines on the screen wires (blinding). www.deister.com Elrus Elrus Aggregate Systems' inclined vibrating screens maximize flow and coverage for increased production with minimal maintenance and downtime. By focusing on the three essential fac- tors of shaft design – speed, throw and location – Elrus has developed a screen system that provides efficiency, capacity and gradation control while minimiz- ing vibration transfer to surrounding structures. Elrus screen plants feature: • Hydraulic raise and lower screen and subframe. • Repackable feed chute. • Cantilever overhead conveyor. • Under cat walk screen motor mount. •  Folding blocking legs to accommodate tandem jeep axle. •  Optional full end tension on bottom and middle decks. •  Adjustable height on overhead conveyor. • Two or three cross conveyors. •  Angled cross members on carry decks. • Hydraulic leveling. www.elrus.com
