Even loads thanks to hydraulics

Hytec recently commissioned the R10-million hydraulic system 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 Hytec System Sales Manager, Klaus Marggraff.

The two stackers, manufactured by ELB Engineering Services, 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 600ℓ/min of hydraulic flow is required at specific stages of the loadout station, which also needs to deliver precise distribution control within each wagon with strict tolerances.
