Sandvik’s new QA331 portable, three-way split screener features a 14- by 5-foot, two-bearing screen box with an increased 6-degree screening angle built into the bottom deck of the screen. Other features include a larger screening surface area, increased throw on the screen box, an I-beam design for maximum durability, a folding access walkway around the screen box to provide easy access for maintenance, a 7-cubic-meter-capacity hopper with a radio-controlled tipping reject grid, and a main conveyor fitted with a 1,050-millimeter heavy-duty belt. The unit’s tracks are 500 millimeters wide.

Screen Machine Industries, Inc.

Screen Machine says its new patented Spyder 512T portable screening plant opens up a new size class of machine. The plant has the same engineered features as its predecessor, the 516T. Features include a 5-foot by 12-foot double-deck, two-bearing screen; Grade 80 high-strength steel construction; and the ability to place materials in windrows in three different sizes with remote operation.

Inertia Machine Corp.

According to Inertia, its new prototype 620 Spec Maker portable screening plant offers a compact design for portability on its own triple-axle chassis, yet delivers 20 percent more screening capacity compared to standard models. The unit features a 6- by 20-foot double-deck, inclined screen; its own onboard fold-down feeding, transfer, side discharge, and stacking conveyors; and a 48-inch belt feeder with hopper and grizzly. It can be combined with any crushing plant in the company’s line to create a closed-circuit operation, without the need for additional transfer conveyors.

Metso Minerals

Metso says its new Lokotrack ST3.5 can produce two-sized fractions, with an optional two-deck vibrating grid that can be installed to yield three-sized fractions. The unit features an 11-foot, 7-inch by 5-foot screen box with a 57-square-foot screen area and is powered by a 100-horsepower Cat 4.4 engine. Four identical meshes are used on the screen to lower stock requirements.
