New Process tailings dry exhaust system is Division I after years of practice and technological improvements, and mining enterprises, to discuss and explore practical new tailings out new technology. The tailings treatment process small investment, high returns, especially for the treatment of dry sand tailings discharge. Our free tailings treatment process after successful pilot Hebei, Hebei, Sichuan Panzhihua, Shaanxi and other places have been widely used, effective solution to deal with the problem of tailings beneficiation enterprises. New Process tailings dry exhaust system description: tailings → cyclone (or thickener) → dry tailings underflow → → row sieve sieve reach dry heap, dry row, next screen → sedimentation pond or tailings or pressure The exhaust filter machine dry tailings technology system equipment required: 1, slurry pumps, cyclone 2, tailings dry sieve row 3, filter 4, other transportation equipment owned craft system flow analysis: ore after crushing After the formation of magnetic screening milling tailings, mill tailings out at about 20% concentration, the tailings slurry with a slurry pump into the cyclone, the bottom of the cyclone flow into the tailings dry sieve row, after the end of row after mine dry sieve jobs dry tailings discharged water content of about 15% can be achieved dry stack and transport requirements, muddy water flows into the tailings pond bottom or you want to reach the backwater into the settling tank can be utilized again with a filter press. The small return on investment in high technology, and has a certain degree of flexibility, all aspects of the device can have the choice to select, for example, does not have to reach backwater use only on dry tailings discharge cyclone + screen can meet the requirements, if the follow-up The backwater want to use can be combined to achieve the filter and other equipment. Concentrator tailings pile dry dry exhaust treatment can effectively avoid the risks faced by tailings inventory, and small footprint, low cost of subsequent production, dry tailings discharged from the building materials can be used to do, increase their ROI; concentrator is water users, conducted tailings return water utilization can reach more than 80%, severe water shortages in the region have obvious advantages to reduce environmental pollution. Advantage of a dry tailings row, row using dry tailings technology to solve the traditional way of tailings discharge, environmental pollution, dam hazard and take up a lot of land in question; 2, concentrated tailings dewatering, dry emissions you can save the cost of a traditional tailings pond construction and routine maintenance costs, but also make full use of artesian backwater, play a role in energy efficiency. 3, dry tailings variable discharge waste into treasure, utilization, such as filling gob eliminate safety hazards, restore landscape reclamation, environmental governance save money, protect the geological environment, to achieve a waste substitution.
