Taking rugged screen design to new heights

Spartan-based vibrating screen specialist Kwatani is building one of its strongest and heaviest screens yet, to undertake punishing duty at a South African iron ore mine.

The 54-tonne scalping screen – measuring over 10m in length and with a 3.7m width – is a single-line unit that handles about 7 000t of run-of-mine iron ore an hour. It takes feed from a primary crusher with a top size of 400mm, although the dimension of these boulders may still be up to 800mm long.

Vibrating with a stroke that applies around five times the gravitational acceleration (5Gs) on the material, the mass of the rocks is effectively increased by five times. The unit’s single-line status makes it a key piece of equipment on site, with several parts of the process plant heavily reliant on its throughput.
