Process flow of sand production line

The beneficiation production line refers to the extraction of some elements from the raw ore mined by the mine through certain complex beneficiation process and equipment, and the refined concentrate powder is used for smelting and industrial foundation. The beneficiation production line consists of a complete set of beneficiation production lines according to the types of minerals: iron beneficiation production line, lead-zinc ore beneficiation production line, tungsten manganese ore beneficiation production line, copper beneficiation production line, silver beneficiation production line, etc.

The whole set of beneficiation production line is composed of jaw crusher, high-efficiency energy-saving ball mill, grader, dry-wet magnetic separator, flotation machine, thickener, dryer and other main equipment. The complete beneficiation production line can be formed with auxiliary beneficiation equipment such as feeder, elevator, conveyor and so on.

Process flow of beneficiation production line

The production process of the lead-zinc ore, copper ore and iron ore beneficiation production line is as follows: the mined ore is initially crushed by the jaw crusher, and after being crushed to a reasonable fineness, it is evenly sent to the ball mill by the elevator and feeder. The grinding process of the metal beneficiation production line is crushing and grinding the ore by the ball mill. The fine ore grinded by the ball mill enters the next process: classification. The spiral classifier cleans and classifies the ore mixture by virtue of the principle that the specific gravity of solid particles is different and the speed of precipitation in the liquid is different. When the washed and graded mineral mixture passes through the magnetic separator, the magnetic substances in the mixture are separated by magnetic force and mechanical force due to the different specific magnetization coefficients of various minerals. The mineral particles after preliminary separation by the magnetic separator are sent to the flotation machine, and different drugs are added according to different mineral characteristics to separate the required minerals from other substances. After the required minerals are separated, because they contain a large amount of water, they must be initially concentrated by a thickener and then dried by a dryer to obtain dry minerals.
