How To Make The Most Of The Magnetic Separator
With in-depth development of the domestic and foreign high-performance permanent magnet materials
, the industrialization of magnetic separation equipment as well as the constant optimization, upgrade and promotion of traditional permanent magnetic separator magnetic system and body structure has accelerated the process that permanent magnetic separator equipment gradually takes place of electromagnetic separation equipment. With the application of automatic control technology and monitoring technology in domestic and foreign mining enterprises, the automation level of mining equipment manufacturing is improved correspondingly and the accuracy requirements of the field of magnetic mineral separation is becoming higher and higher. Currently, the development tendency of magnetic separator mainly includes the following four trends:
At present, the ore tailings in China annual discharge about 0.4 billion to 0.5 billion tons, taking account one third of industrial waste. Among them, metal ore tailings take 25%, metallurgical slag takes 26%, chemical slag takes 4%, and coal fly ash and coal slag take 35%. Metal recycling and processing will no doubt use magnetic separator and other matching equipment. Ore tailings process makes use of gravity and magnetic concentration production, so as to recover iron ore from ore slag. As for different metals recycling from tailings, we have to use spiral tank, shaking table and magnetic separator matching with different ore dressing process. For the time being, the advanced equipment such as disk magnetic separator for weak magnetic field, drum magnetic separator with big drum diameter for medium magnetic field and high gradient magnetic separator have been applied to metal concentration process.
In recent years, Poland adopts the pointed shrinkage loop re-election process in the lead and zinc sulfide ore ore-milling classification to recycle 0-1mm fractionated part of the galena, to avoid its losses in residue economically and effectively, and improve the condition of flotation circuit conditions.
Dry magnetic separator is a new type of high efficiency magnetic separation equipment which produced by Hongxing mining machinery company. The whole magnetic system made up of high performance rare earth Neodymium Iron Boron materials and high quality ferrite materials. A cleverly open magnetic circuit design makes the highest magnetic induction in tube sheet selection field be up to 0.8T, which is 3-5 times of the conventional magnetic machine. The magnetic force in magnetic selection field can achieve strong electromagnetic magnetic separator level.
According to the characteristics of flotation subject, people often complete the check, record, adjustment and stability work of operating parameters by using automatic instrumentation and control devices, the flotation separation process control usually includes flotation process equipment order control, Administration of the amount of feed forward control, the slurry pH value control, pulp potential control, pulp flotation inflatable control, flotation cells level control.
Since the 19th century, the magnetic separation process has been used for beneficiation. In the 1970s, the more economic magnetic separator was discovered. In addition, iron ore magnetic separation is used in many mineral processing.
As a professional manufacture of wet type and dry type magnetic separator, permanent-magnet drum separator, concentrated magnetic separator, high strength magnetic separator, dehydration and shrinkage separator, our company has many years in the research and development of magnetic separator with reliable product quality and first-class service which is always your best choice.
