White corundum micropowder production line

 White corundum is made from industrial alumina powder, which is smelted in an arc at a high temperature of more than 2000 degrees and then cooled. It is suitable for the manufacture of ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc. It can also be used to manufacture high-grade refractory materials. The code “WA” is consistent with international general standards and national standards.  Most of them are for export, and a certain amount is also supplied to domestic users.

White corundum micropowder processing line

White corundum powder is hard and brittle and has strong cutting force. It can also be used as catalyst, insulator and precision casting sand. Several precautions should be paid attention to when grinding.


1. Physical and chemical utensils, spark plugs, heat-resistant and anti-oxidative coatings.


2. Due to its high temperature resistance, corrosion resistance, high strength and other properties, cast steel sliding nozzles are used to smelt rare and precious metals, special alloys, ceramics, and the lining of iron-making blast furnaces.


3. Due to the characteristics of high hardness, good wear resistance and high strength, white corundum micropowder can be used for processing various reaction vessels and pipes, and parts of chemical pumps in chemical systems.


4. Make mechanical parts, various molds, such as wire drawing dies, extruding pencil core die mouths, etc., make knives, mold abrasives, bulletproof materials, human joints, sealing die rings, etc.


White corundum micropowder can be used as solid structure and coated abrasives, wet or dry blasting sand, suitable for ultra-fine grinding and polishing in crystal and electronic industries, as well as making advanced refractory materials.

The classifications of quartz sand

  1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.

Chromite purification processing method

At present, chromium ores with industrial value are generally chromium-magnesia spinel or chromium-iron spinel minerals, which contain a large amount of chromium oxide, with a content of about 18% to 62%, and generally also contain metals such as aluminum and nickel. Its characteristics make the chromium ore beneficiation process present a rich and diverse state. Due to the properties of chromium, chromium ore beneficiation processes include gravity separation, magnetic separation, flotation, combined beneficiation, chemical beneficiation, etc. Commonly used in industry are single gravity separation, single magnetic separation, and gravity-magnetic combined beneficiation processes. In terms of equipment selection, shakers and jigs are mostly used in the gravity separation stage, while the equipment selection in the magnetic separation stage is determined based on the magnetism of the ore.

Sandblasting nozzle classification and use

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently. Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle , double Venturi sandblasting nozzle, angle sandblasting nozzle Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.
