<p>Modifications to existing vibrating screens as used in the mining industry for the separation of ore particles are disclosed. In one form the improved screen assembly (10) comprises a first screen section (11) followed by a second screen section (13), screen section (11) being of a different nature to screen section (13). In a particular form the first screen section (11) comprises a banana screen and the second screen section (13) comprises a non-blinding screen. In an alternative form, the improved screen assembly (32) comprises a non-blinding screen excited by a linear motion exciter (35). These structures provide improved efficiency of throughput of material, particularly 'sticky' materials in certain embodiments.</p> |
