NavigationSeparating Work for Stones Crushed by Rock Crusher
During the separating process, crushed stones are classified into useful ores and foreign matters. According to the physical performance, separating machines are classified into gravity concentrating equipment, magnetic separating plant and flotation equipment. In general, ore separating machines work with screens.
If iron weighs 5t/m3 and foreign matters weighs 27t/m3, we can use gravity separating machines since the weight gap is great. Gravity separating machines are mobile screening plant, spiral classifier and cyclopneumatic separator. Processing stones with gravity separating machines is the most cheapest.
Stones to be processed can be a little thick, with diameter scope from 0.1mm to 1.5mm. Magnetic separating plant is used to screen mineral ores from foreign matters according to the magnetic property. It is only used to separate iron ores. Rotary drum has permanent magnet inside.
When rotary drum revolves, magnetic ores in ore pulp will adhere on drum and be separated out from water. For foreign matters without magnetic property, they will still in water. To separate the hematite, we can use machines with strong electromagnet inside. Magnetic separating plant is more and more used to screen mineral ores with diameter changing from 0.05mm to 1mm.
Flotation machine is used to separate ores from foreign matters according to the difference of hydrophilicity. It is suitable to separate ores with diameter changing from 0.01mm to 0.1mm. In general, flotation machine is used to improve the grade of ores or to screen out foreign matters like sulfur or phosphorous.
If mineral ores and foreign matters are both hydrophilic, we can put into medicines and make one of them hydrophobic. Click website to get the price list of rock crushers!
