First, the summary of scientific research Sand gold dry wind laminar boundary layer method and equipment of the main researchers Zhang Xiaolin Yi Nansheng Ren Hai cost results using the wind boundary layer structure and the principle of affixed jets developed gold sand blasting machine Xinjiang Hetian gold 0.36 - 2mm of placer gold; enrichment ratio as high as 97-173, the recovery rate of 92-98%; adaptability, excellent sorting index, with novelty. Equipment system as a whole portable models; Weight 0.51 tons, 1.31 kW motor power, processing capacity of 0.12 tons / Taiwan. It provides an efficient separation equipment for the development and utilization of ore deposits in Xinjiang or other similar dry areas. December 21, 1991 through the China Nonferrous Metals Industry Corporation organized experts appraisal, is the first at home and abroad.
