Wilfley Table - 911Metallurgist

The Wilfley table is a genuinely unique gold concentrating table first developed over 120 years ago. This Wilfley Table unit is driven by head motion with a stroke adjustment of between 8mm and 16mm (nominal).; Head motion is self-lubricating. Simple, robust design requires minimal maintenance. The deck is supported on sixteen carriers and is vibrated diagonally along the entire length.

History – Holman Wilfley

The first ever shaking table was patented in America by Arthur Redman Wilfley in 1896. By the 1930’s over 25,000 ‘Wilfley Tables’ were being used globally. Whilst in the UK, from 1908, the Holman Brothers of Camborne were selling an exclusive patent of the radically different South African designed James Table.
