What is the sieve hole size of the dewatering screen

The size of the dewatering screen has a great impact on the efficiency of the equipment. Generally, manufacturers have a set of solutions to meet the needs of different customers.

There are many shapes of sieve holes in dewatering sieves, common ones are round, square and rectangular. Compared with sieve holes of other shapes, round sieve holes can pass through the sieve holes with the same nominal size. The particle size of the product under sieve is smaller. The particle size of the particles that actually pass through the round sieve holes is only the average size of the particles passing through the square sieve holes of the same size.

The effective area of the sieve surface of the rectangular sieve is larger. The production capacity is higher. When dealing with materials with more water, it can reduce the clogging of the sieve surface. . Therefore, when it is required that there is no fine powder in the sieve, strip and flake particles are allowed in the sieve, the material is wet and sticky, and it is easy to block the sieve holes, and the content of the sieve is expected to be high, you can use the long sieve. Square hole mesh.

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.
