Integrated Process of Industrial Ore Dressing

Ore mined first by the initial jaw crusher broken by the crusher to a reasonable degree of fineness by the elevator after, even into the mill to the mine machine, crushed ore from theball mill grinding. After cleaning and grading of the mineral mixture in through the magnetic separator, due to a variety of different minerals than the susceptibility through magnetic force and mechanical force to the magnetic material mixture to separate. In the minerals to be separated out, as it contains large amounts of water, subject to the initial concentration thickener, and then by drying machine drying, you can get dry minerals. Iron ore beneficiation process is the most commonly used as a dressing process, relatively coarse ore extraction, the process requires more rigorous and meticulous, iron ore beneficiation technology improved, more conducive to the development of China’s steel industry, producing quality products Enhance the process of steel in the international competitiveness and quality, in addition to technical studies, the device also requires constant innovation, optimization, and create new standards.
The production of ore dressing is a complex process, with the transition and transformation of substance and energy. It has the characteristics of time-variation, large lag, complex mechanism and lots of affecting factors, with the performance of consecution in large range, nonlinearity and tight coupling, which is complex and indeterminate.
The product process of raw ores is to sieve the raw ores to the ore fines of 0 to 15mm and ore lumps of over 15mm. the ore fines are sent to the strong magnetic cylindrical ore storage bin by the belt conveyor as the materials of the product of strong magnetic separation. The ore lumps are sent to the bunker in front of the furnace through two-times screening by the belt conveyor as the materials of the roaster. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like mobile jaw crusher, Henan Hongxing is always doing the best in products and service.rock pulverizer: http://www.crusher-machine.com/n217.html
The process of roast working of the shaft furnace is to send the ores to the shaft furnace to be roasted, which can separate the ores to the waste rocks and valuable ores. The waste rocks are sent to the hillock by the belt conveyor and the winching system, while the valuable ores are sent to the weak magnetic cylindrical ores bin as the product of the materials of weak magnetic separation.
The working process of ore grinding and magnetic separation can be divided into the strong magnetic separation and weak magnetic separation. The primary of the ore grinding system is a closed circuit made by the ball mill and the separator, while the secondary is a closed circuit consisting by the ball mill and the water cyclone. The undersize sieves are embodied in both of the two ore grindings to control the particle sizes feeding the secondary from the first separation. The ore fines or the roasted ores are classified by the classifier after grinded by the ball mills.
To ensure the sorting effect, the pulp must have the certain residence time in each flotation cell and the too long time or too short will result in the loss of useful minerals, reducing the operation recovery. Therefore, the specifications of the flotation machine should be in line with the scale of dressing plant.
