Hytec recently commissioned the R10 million hydraulic systems it supplied for the new bulk handling equipment installed at Assmang’s Black Rock Mine Operations in the Northern Cape. This bulk handling system includes two stackers, a bucket wheel reclaimer and a rapid load-out station – each automated using Hytec’s proportionally controlled hydraulic systems assembled from Bosch Rexroth technologies.
“The proportional control achieved by the system delivers precise remote flexibility in adjusting, varying and optimising the load handling characteristics of the machinery to accommodate any changes in the nature of the material,” explains system sales manager, Klaus Marggraff.
The two stackers were equipped with 7,5 kW hydraulic systems that will control the stacking of manganese ore in the stockyard in various grades of material. The bucket wheel reclaimer was supplied with a 45 kW hydraulic system and includes dual luffing cylinders. At the load-out station, Hytec’s hydraulic systems extend from the control of the exit gates of the loading bin, across the weigh flask that divides the load into batches that are then transferred into the wagons below. Up to 600 l/min of hydraulic flow is required at specific stages of the load-out station, which also needs to deliver precise distribution control within each wagon with strict tolerances. “Each component used on the system, from valves, cylinders and the filtration systems filtering the oil down to six microns to the control, is from the Bosch Rexroth range of drive and control products,” Marggraff concludes.

Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
