Self-Cleaning Rubber Screen Media

Dur-X-Kleen® self-cleaning rubber screen media is designed with molded, tapered openings, flexible self-cleaning action, with screen openings remaining clear so material flows at full capacity. Available in harder or softer rubber designs to fit any application, the line is a result of ongoing innovations and a proprietary rubber formula delivering superior abrasion, tear-resistance and increased wear life. Suited to applications involving dry, high-impact material or fine, sticky or near-size material, rubber screens absorb high impact. When installed in a vibrating screen box, the rubber screen's flexibility presents amplitude greater than the stroke of the machine. Combined with tapered openings, a self-cleaning action is realized. Fines will not blind/plug surface and rejected particles are thrown out. Available in a variety of mounting styles, the media can be custom-designed in bolt-down, modular or side-tension versions fitting any existing screen box. Modular systems snap into place and can be installed by one person.

Wear Plate/Tooth Systems

Caterpillar introduces Mechanically Attached Wear Plate Systems (MAWPS) and Cat® KSeries Tooth System™. The tooth system represents a multitude of improvements including an expected tooth life increase by up to 15 percent, lower tooth profile provides better penetration and sharpness is maintained longer. Available in 11 options, tips can be changed with a "twist-on" procedure making installation easier, quicker and reduces tip movement by allowing the tip to grip the adapter tighter as it digs harder into tough materials. The Wear Plate systems, made from Caterpillar's formulated DH-2™ steel, slide onto weld-on base plates and are held in place with a patented compression retainer. Low retainer placement allows for a greater percentage of the wear plate to be used before replacement. Recessed holes in each plate corner serve as wear indicators. Plates can be removed in two minutes or less using a special removal tool or a common pry bar.

Carbide Inserts

The Marathon carbide insert for button bits by Rockmore International combines higher hardness properties with longer-lasting performance to handle extreme, abrasive rock-drilling conditions. The carbide grade uses a newly developed manufacturing process to improve overall bit performance for a variety of down-the-hole (DTH) hammers and a broad range of drill-rig models. Introduced as a "new generation" of carbide inserts for button bits, Marathon carbides employ microstructural design changes to provide increased hardness while maintaining optimum toughness characteristics that resist catastrophic fracture. Extensive rock-drilling trials showed that the carbides last up to 20-percent longer than previous designs in water-well and mining environments. Wear flats appeared slower and later in the carbide life when compared to inserts with traditional composition. Marathon carbides are available for all DTH bits designated for water-well drilling up to 10 inches in diameter with button sizes up to 3/4-inch.
