Nowadays, most mineral processing plants adopt wet ore dressing process, but the concentrate and tailings often contain high moisture content, which cannot be smelted directly. In addition, the water content of concentrate and the utilization ratio of tailings recycling water will directly influence the transportation cost and investment cost. That means dewatering machine is an essential link in ore dressing process.
As the professional thickener manufacturer in the world, Xinhai has successfully developed various types of rake thickener, deep cone thickener and tilted plate thickener, which perfectly achieved the free sedimentation among 20-3500 ㎡, fully met the production demand of various ores and scales.
As the next dewatering device after thickening, Xinhai also put enough effort into on filtering equipment. It has developed and improved many types of filter and dewatering screen, which fully ensured the concentration of concentrate and tailings can reach the standard, and the concentrate moisture can decrease from 45-60% to 10-18%, then Xinhai also successfully applied for many national patents.
With the help of CFD model, 3D model system and other professional design theory, Xinhai has successfully produced the leading high-efficient hydrocyclone in the world, which can be combined with each other for adapting to different process requirements. The thickening and dewatering efficiency was up to 80% ~ 90%; At the same time, the hydrocyclone was lined with Xinhai wear-resistant rubber that extended service life of 2-4 times.
Xinhai Iran Arasbaran 300 tpd gold flotation project adopted "stage grinding" – single stage gravity separation - stage flotation” process, the processing capacity was up to 350 tons per day, and 5000 tons high-grade gold concentrate can be produced every year. In the dewatering operation, the gold concentrate was pumped to XMZG60/1000 disc vacuum filter for dewatering, the filter cake was transported and stored by belt conveyor; the tailings was sent to XMZ350/1500 press filter for dewatering, the filter cake was transported to tailings pond for storage. Finally, the water content of gold concentrate was only 12%, and the water content of tailings was reduced from 70% to 15%.
Since its establishment, hundreds of technical experts in Xinhai machinery institute has optimized 80% common dewatering equipment, and won more than 10 national patents. They strived for providing you with the best dewatering equipment.
In the over 20 years, Xinhai successfully won the approval and praise from many well-known enterprise at home and abroad by its excellent technology and service strength. More than 500 mineral processing EPC plants were all around over 90 countries and regions.
Meanwhile, Xinhai set up the large and standardized service guarantee system, which effectively guarantee to convey information timely and provide the most professional service and technical support to customers immediately.
