Quartz sand making machine equipment sale price
Quartz is also called silica.From silicon mineral silicon silica sand or silica sand concentration process.Industrial silicon dioxide and impurity content conform to the requirements of the use of quartz, quartz sandstone, quartzite of arteries and veins are collectively referred to as silica.And quartz lake, river sand, sand of the sea sand is called the silica sand.Theory of pure silicon, silica sand, chemical composition is sio2.Related impurities mineral mica, feldspar, including iron ore, clay and so on.Glass industry is one of the biggest silicon and silicon sand of users, in addition in metallurgy, chemical industry, building materials, electronics and other industrial sector is also widely used.Used in the metallurgical industry, smelting ferrosilicon silica or silica sand is divided into different levels according to the chemical composition;Refractory products in addition to the demands of its chemical composition, also requires refractoriness, density.
Commonly used preparation methods are washing, grading, scrub, gravity separation, magnetic separation, flotation, chemical processing, etc.Ore dressing process flow should be according to the ore properties and the requirement for the quality of concentrate.Undressed ore chemical composition of the pure silica used wet or dry broken a grinding classification process can produce qualified products.Impurity mineral more ore or demand is high, the quality of product is joint process, including several kinds of mineral processing methods such as scrubbing a des magnetic separation (or heavy) a flotation process.The principle of silica or silica sand dressing processes as shown.Such as ore is silica, ore should be after crushing, screening, grinding, and then enter the sorting operation;Undressed ore is dry sands, into the water should be taken before sorting operation for the pulp to screen out the coarse particles;Undressed ore is wet sands, to screen out the coarse particle separation.Flotation is an important method to improve the quality of silica sand concentration.Flotation is often to be under the condition of thick slurry before strong stirring, to remove iron oxide film on the surface of the mineral and slime, or the use of magnetic separation, gravity separation methods such as removing of ore minerals.
According to the ore mineral composition, flotation technology is also each are not identical:
1.iron but little or no mica, feldspar minerals, but under the condition of alkaline pulp, using tal oil or petroleum sulfonate to contain iron ore, reoccupy amine collector choose quartz concentrate;
2. the mineral feldspar is more, other impurity content, available amine collector of quartz and feldspar mixed concentrate are selected, with hydrofluoric acid activation and amine collector to feldspar, groove products for quartz concentrate;
3. feldspar and iron content of more, do not contain mica mineral, can, in turn, the way to iron ore, feldspar, quartz and flotation.
4. including iron ore, mica and feldspar ore can be under the condition of acidic slurry with amine collector first elected mica, and then, in turn, flotation of iron ore, feldspar, the final product is a quartz concentrate groove.
Quartz processing equipment
Silicon ore, quartz ore hardness is higher, so the choice silicon ore, quartz ore processing equipment, it is important to note that the equipment can according to material hardness.Silicon ore, quartz ore processing equipment including: crusher (jaw crusher, counterattack crusher, sand making machine (the third create sand machine, impact type sand making machine), milling machine, high pressure mill, Raymond mill, ultra fine mill), the dryer (tumble dryer, three return dryer), auxiliary equipment: vibrating feeder, belt conveyor, hoist, charter flights.
Is bound to run out of natural sand, artificial sand will become part of the main building gravel. If you want to know more information on this quartz sand Sand welcome chat online with us, it’s free.
