Nominated for an innovation award in the machinery component category, Bauer Maschinen’s down-the-hole (DTH) flushing head for dry drilling rods will be on show at Bauma. TABE will show off its new hydraulic breaker and crushing bucket, whilst SBM Mineral Processing will exhibit its redesigned universal crushing series. Dana’s drivetrain solution for front-end loaders, Hazemag’s new wobbler feeder and underground loader, and a selection of Siemens’ products will also be displayed.
Bauer’s DTH innovation has been successfully trialled in Finland (May 2009) and, since then in Vladivostok, Russia. Upon reaching the rock layer, the flushing head can be used – together with the subjacent roller bit full section drilling head, or roller bit core barrel – coupled to the Kelly bar. An air supply hose, which is coiled outside the borehole, is connected to the flushing head. Air flushing is conducted by the rotor via a pneumatic multiport swivel. This drives the flushing by risers in the tool, with the rock chippings permanently transported to a tank in the upper part.
Spanish company, TABE’s AGB-40 hydraulic breaker was the first of its heavy duty products to undergo a series of tests carried out by the company in conjunction with the Aragón Technology Institute. It can be used with machines between 45 and 70 t and has a service weight of 4,850 kg. The crushing bucket comes in two models: the GT-25 V2 and the GT-35 V2, of 2,650 kg and 3,900 kg weight respectively. Both are designed to turn waste into gravel or crushed stone.
SBM has redesigned its universal crusher series and brought them together in the new Series 13. The 13/16/4 RHSMK-3 impact crusher has a fully hydraulic impact apron. This model combines mechanical and hydraulic adjustment and guarantees good protection when foreign bodies enter the crushing chamber.
Hazemag’s VARIOwobbler® wobbler feeder can be used in pre-screening operations in crushing plants and allows easy adjustment of screening parameters when needed. The feeder can be designed as single or multi-stage machines, with the latter helping separate fines from the coarse material. The EL160 loader’s compact design enables its use in narrow spaces in underground operations. At the show, it will present the newly developed version with a gun-mount for blast hole and anchor bore hole drillings.
Dana’s drivetrain solution for 16 t front-end loader applications is through a system that includes a Spicer® 319 summing motor, two Spicer Model 114 planetary drive axles, and the Spicer Compact Series Model 2035 driveshaft. The Spicer 319 summing motor transfer case provides tractive performance and high efficiency. For applications requiring 104 to 164 kW, it employs two hydrostatic motors, each with optimised gear ratios. At higher vehicle speeds, a clutch automatically disconnects the low-speed, high-gear-ratio motor, allowing the high-speed motor to function alone.
Siemens’ displays will be focusing on drive solutions for conveyor systems and mobile mining equipment, such as trucks, including truck trolley systems, shovels and draglines. Furthermore, solutions and systems for fleet management, automation and wireless LAN-based solutions for control and communications systems based on rugged components – used for data transmission throughout the entire mining site – will be presented.
