The paper examines developments in the field of fine aggregate processing equipment. These developments have been brought about by such factors as (1) demand for equipment with increased capacities, (2) difficulties encountered in locating deposits, (3) cost of material transport, (4) the introduction of metrication, and (5) the demands of conservation. Commonly encountered problems to be overcome to bring material within a specification are clay contamination, contamination with organic matter, and, distorted grading due to nature of deposits. These problems have required manufacturers to give more attention to design such as sharper classification either hydraulically or by screening methods. Problems associated with effluents can in many cases be overcome with equipment designed to provide an alternative to settling areas. (TRRL)
