Dressing in the acquisition of mineral raw materials, in accordance with various mineral properties, physical and chemical properties and chemical nature of the differences, elected useful minerals process. The implementation of such a process known as beneficiation of mechanical machinery, processing machinery broken into by the beneficiation process, grinding, screening, sorting (sorting) and mechanical dehydration.
Machinery used a broken
jaw crusher,
cycles Crusher, cone crusher,
roll crusher and counterattack Breakers; Grinding machine is the most widely used roller mill, including rod mill,
ball mill,
mill and the mill gravel; Screening machines were used inertial vibration and resonance sieve sieve ; classifier hydraulic and mechanical grading machine is operating in the wet classification widely used classification machinery.
Mechanical separation by gravity into the role of mineral processing machinery, magnetic separator, flotation machines and special processing machinery. The election machinery in the first gravity processing machinery, the original piston jig in 1830 to 1840 in Germany there for metal ore separation; First Separator (weak magnetic separator belt) was introduced in 1888; Flotation of a late first-mechanical mixing occurred in the flotation machine 1910.
Gravity is the use of mechanical processing and gangue mineral particles in the size and density of the difference in sports media for the separation equipment, including jig, heavy and medium machine processing of centrifugal concentrator.
Jig is using divide and the Pistons or compressed air to form water in the tank water, so that the mine placed on screen in tablets under the pulsating flow density, multi-granularity. Density of mineral particles on the screen through the rock bed, gathered at the bottom of a water tank Concentrate from the row from the entrance. For the separation of metal ore mainly trapezoid jig, double room at the end of cone-jig and vibration-jig; The coal preparation for a side drum jig and Screen Room Air jig.
Dense Medium concentrator is used as a liquid suspension or heavy medium weight, mineral particles and waste separation. The main medium to heavy vibration chute, spin-liquid medium, heavy-medium coal preparation oblique round of legislation and heavy-medium coal-round.
Yes centrifugal concentrator for the recovery of fine slime in the metal ore pieces of machinery, mainly by the host and control institutions consist of two parts. Cone host in high-speed rotating drum by centrifugal force generated in the field, heavy mineral particles to the drum wall deposition become Concentrate, concentrate light attached to the surface of mineral particles by flow membrane (slurry flow), from Drum, a tailings.
Separator is the use of the difference of magnetic minerals, using magnetic and mechanical forces on the role of minerals sorting machinery. Magnetic Separator by the system, separation device, and the mine discharge device components. Separator many types, there are permanent magnet Drum Separator, electromagnetic-ring-high gradient magnetic separator and high-intensity magnetic separation machines.
Flotation machine is the use of mineral particles surface differences in physical and chemical properties of the fine-grained minerals sorting machinery. Mineral particles flotation machine with flotation reagent, or mechanical agitation by compressed air, water wettability not be attached to the mineral particles on the bubble (at the flotation method), to surface, through a discharge device from concentrate, susceptible to water wettability of mineral particles stay in the groove as of the tailings discharge.
Wet Mineral Concentrate from the need to go through dehydration mechanically to make solid-liquid separation. Enrichment can be divided into mechanical dewatering machine, filter, centrifugal dewatering machine and dryer.
Mining machinery equipment included in the broadly as: E-crushing machine, Raymond Mill powder machine, Zhishaji, ball mill, Mianshaozhuanji
