Yantai Golden Ocean cyclone introduced the most advanced tailings dry drainage system, has already been applied in more than 20 mine tailings dry row and promotion, with excellent results. The system solves the major problem of domestic concentrator tailings dry row than the dehydration process saving 2kwh / t, saving to invest 30% -40%, save costs 2-4 yuan / ton dry exhaust is by far the dry drainage the least-cost technology system. 

 Introduction 
 Efficient enrichment cyclone and high-frequency vibration sieve dehydration equipment in times of industrial arrangement with the concentrator tailings slurry from the first into the cyclone through the cyclone concentrated underflow density can reach 65% -70% and bottom currents directly dehydration, dehydration sieve sieve sieve dehydration moisture content up to 16%, the belt conveyor transported to the dry yard to achieve dry heap; sieve material to return to the cyclone feed, cyclone and sieve dehydration to form a simple closed-loop system to ensure that the dry material as far as possible from the dewatering screen output. In addition, the overflow of the cyclone through the deep cone thickener and filter press further dewatering of the tailings completely dry drainage purpose. 
 First two years of site production tests proved that the process does tailings set of effective treatment options, particularly for use in small and medium-sized iron processing plant can reduce the selected field operating costs, to avoid the safety hazards of the tailings dam failure, continuous safety of the security processing plant production, promote the comprehensive utilization of tailings, has a good application value. 

 The main push equipment 
 Efficient cyclone concentrated: the patented product, a unique variable cone structure, involute feed, high classification efficiency 
 Dehydration of high-frequency vibration sieve: sieve the structural strength, polyurethane sieve dehydration effect 

 Technological features: 
 A dry heap better 
 One-time investment, follow-up maintenance costs low 
 3 equipment covers an area of ??small 
 4 short process 
 5 equipment repair and maintenance simple 
 6 to extend the service life of the original tailing dam or tailings dam
