Updated jaw
Powerscreen improved its X400S jaw crusher by incorporating a fully independent, high-amplitude, hydraulically driven pre-screen with increased drop angle on the bottom deck. The company says the pre-screen removes a large percentage of the fines within the feed material before it enters the jaw chamber, resulting in a cleaner crushed product. The discharge opening from the under chute has been increased from 8 inches to 12-3/4 inches, allowing pre-screened material to bypass the crushing chamber quickly. The side conveyor features an increased width from 24 inches to 26 inches and an improved discharge height of 9 feet, 2 inches.

For large-scale operations
IRock Crushers’ new TS-522 heavy-duty screener, one of five models, is suitable for medium- to large-scale operations. The company says it features extra hopper capacity, a class-leading screening area, and the highest stockpiling capability of any screener of its size. The screener is capable of processing materials at a rate of up to 670 tons per hour. The unit’s 14-foot-wide hopper feeder is rated to 12 cubic yards. A 22-foot by 5-foot top deck and a 20-foot by 5-foot bottom deck offer a total screening area of 210 square feet. The two-deck design allows users to produce and sort up to three different size products. A three-deck version that can sort four sizes is also available. Hydraulically folding side conveyors are able to stockpile up to 16 feet, 8 inches; the tail conveyor can stockpile up to 16 feet, 2 inches.

Nimble dozers
Komatsu says its new line of D37-23 and D39-23 crawler dozers — designed using customer feedback — are smarter, more productive, and operator friendly. The dozers offer new operator-specific features in a compact 89- or 105-horsepower package. Operating weights range from 18,386 pounds to 21,363 pounds, depending on configuration and model. The steeply sloped engine hood and forward cab design provide improved blade visibility. A newly designed PAT blade features a durable box structure and good curvature for rolling material. Standard adjustable blade pitch allows the operator to adjust the aggressiveness of the cutting edge.
