Abstract
A shielding device 23, 24, in apparatus 1 for screening ore or like material includes an elongate body portion 25 for location over the top surface 7 of a support beam 3 of a support frame for screen panels 6. The shielding device includes at least one skirt 26 projecting from a side of the body portion 25. The device is locatable between the screen panels 6, a fixing member 13 for the screen panels and the beam 3 and provides a surface 27-27a for collecting fines material that ingresses between the screen panels 6 and fixing member 13 and deflecting it away from the beam 3. Use of the shielding devices reduces wear on the support beams 3 due to the abrasive fines material. The shielding devices are consumable items and can be replaced.
