Metso Minerals' new Lokotrack ST458 mobile screening plant has been designed for improved reliability and productivity, according to the company. The 69,000-pound ST458 is constructed with heavy-gauge materials and is mounted on twin 15æ-inch-wide, hydraulically driven tracks. The feed conveyor assembly has been mounted as a cassette and the entire unit can be removed through the rear hopper door, providing full access to the conveyor belt and all conveyor components. In standard configuration, the unit is capable of producing three sized fractions, and an optional two-deck vibrating screen can be fitted to provide four fractions. Metso says the loading width of 15 feet 3 inches and hopper capacity of 9.6 cubic yards is the biggest feed hopper available in its size class. The unit's two-bearing screens feature 85 square feet of screen area per deck. Power is provided by a Deutz BF4M1013EC four-cylinder, liquid-cooled diesel engine rated at 148 horsepower.

Screen speed and amplitude in conjunction with conveyor speeds are monitored and adjusted for optimum productivity and classification accuracy. Remote- and radio-control options provide for safe movement around the job site. Process adjustments and tipping of the grid also are possible from the radio remote.
