Yantai Golden Ocean cyclone Co., Ltd. introduced the most advanced dry tailings discharge system, has more than 20 mines in the country ranked in dry tailings has been applied and promotion, with excellent results. The system solves the concentrator tailings dry exhaust domestic major problems other than dehydration saving 2kwh / t, 30% -40% savings in investment, saving the cost of dry-row 2-4 yuan / ton, is by far the dry exhaust lowest cost of a process system. 

 Introduction 
 Times using high concentration of industrial and high-frequency vibration dehydration cyclone devices with screen layout, the tailings slurry from the concentrator into the first cyclone, the cyclone concentrated underflow density can reach 65% -70% at the end of direct flow through the sieve dehydration dehydration, dehydration sieve sieve moisture content of 16% or less, with the belt conveyor transported to the dry yard time to dry stack; sieve material to return to the cyclone feed, cyclone and dewatering screens that form a simple closed-circuit system, to ensure dry material from the dewatering screen as output. In addition, the cyclone overflow through the deep cone thickener and filter press for further dewatering effect to completely dry tailings discharge purposes. 
 After a year on-site production testing proved that the process really is an effective tailings disposal programs, particularly for use in small and medium sized iron processing plant, can reduce the selection field operating costs and avoid tailings dam break the security risks, security selection continuous plant safety, promote the comprehensive utilization of tailings, has a good application value. 

 The main push equipment 
 High concentration of cyclone: ??patented product, a unique variable taper structure, involute feed, grade and high efficiency 
 High-frequency vibration sieve dehydration: sieve structure, high strength, polyurethane sunburn, dehydration effect 

 Process characteristics: 
 A dry stack effect 
 2 one-time investment, ongoing maintenance costs low 
 3 equipment, small footprint 
 4 short process 
 5 simple equipment repair and maintenance 
 6 to extend the original tailings or tailings dam for the service life
