November 2009 – RollOuts
Astec Mobile Screens says its new Multi-Frequency Screen is the most versatile screen on the market. The company says the unit allows for flexible sorting diameters and frequencies, without sacrificing performance or profit. According to the company, the screen integrates conventional and high-frequency screen movements to help maintain a higher production rate, which makes wet materials easy to manage. The screen can apply more amplitude and less frequency for coarse materials, and less amplitude and more frequency for finer materials. A low operating angle allows for safer maintenance and operation.
Next generation belt cleaner
Flexco says its new MHS Cartridge Cleaner is the mining industry’s first true slide-out cartridge cleaner. The unit slides out from one side of the conveyor or chute wall, allowing a single worker to inspect, service, or replace it in minutes, thereby minimizing downtime. The side slide-out design is also safer for workers, as it doesn’t require them to crawl underneath the conveyor or be in tight spaces within a chute.
Track-mounted mobile crusher
Sandvik’s QJ340 track-mounted mobile jaw crusher, formerly Fintec’s F1107 mobile jaw crusher, is powered by a C-9 engine that meets all known emissions standards. The company says the unit boasts a large feed opening and high crushing speed that delivers high outputs and excellent product size reduction. A reverse crushing action relieves blockages. Other features include hydraulically adjustable CSS for a variety of applications, a Vogel automatic central lubrication system to increase machine up-time, hydraulic legs for increased stability and servicing capabilities, and more.
High shear, natural attrition
McLanahan Corp.’s “ultra-clean” attrition scrubber uses radial and axial turbines to create high shear and natural attrition to address sand equivalency and durability problems in natural construction sands (as well as for surface cleaning of mineral sands and in soils washing applications). The company says the units are more power efficient and occupy a smaller footprint compared with blade mills or conditioners, yet have a more aggressive particle action; and that custom design agitation intensity and superior tank hydrodynamics lead to cost-effective installations compared with typical industry attrition cells.
