Application characteristics of re-election equipment and sorting size range Equipment type Sorting granularity (mm) Application characteristics general maximum Minimum The crude grain reselection device Heavy medium dressing equipment Vibrating chute Drum sorter Cone sorter Eddy current sorter Heavy medium cyclone 75 to 6 100 to 6 50 to 6 35 to 2 20 to 2 100 300 75 75 35 3 5 1.5 0.5 0.5 The sorting granularity is coarse, the processing amount is large, and the sorting precision is high, and it is suitable for pre-selecting ore with high depletion rate. Medium preparation and recycling process system is complicated Rectangular large jig 5 0 to 10 70 0.074 The sorting precision is coarse, the processing amount is large, and the process is simple. Sorting accuracy is not as good as heavy medium in grain weight selected Assume Prepare jump Eliminate machine Side-by-side diaphragm jig Lateral diaphragm rectangular jig Reverberation jig Round jig Lower cone jig Guangdong type jig Trapezoidal jig 1 2 to 0.1 12 to 0.1 12 to 0.1 12 to 0.1 6 to 0.1 6 to 0.1 5 to 0.074 18 18 18 18 20 10 10 0.074 0.074 0.074 0.074 0.074 0.074 0.037 Large processing capacity and high enrichment ratio for rough selection and selection Taiwan floating 5 to 0.2 6 0.074 It can separate coarse-grained sulfide minerals, with many products, high sorting efficiency and small processing capacity. Sand mine re-election equipment Shaker 2 to 0.037 3 0.02 Small processing capacity, high enrichment ratio, a variety of products, more for selection Spiral concentrator Spiral chute Fan chute 2 to 0.1 0.6 to 0.05 1.5 to 0.074 3 1.5 2 0.074 0.037 0.037 The processing capacity is larger than that of the shaker, saving water and electricity, and the structure is simple. Low enrichment ratio for rough selection Cone concentrator 1. 5 ~ 0.074 2 0.037 Large processing capacity, water and electricity saving, small floor space, low enrichment ratio, used for rough selection Sludge re-election equipment Centrifugal concentrator 0.07 4 ～ 0.01 Large processing capacity and low enrichment ratio for coarse mud mining operations Various belt chutes 0.07 4 ～ 0.01 Small processing capacity and high enrichment ratio for slime selection CAT Pump,CAT Engine Pump,CAT Hydraulic Piston Pump,CAT Engine Fuel Transfer Pump GRH , https://www.grhcn.net
