Oil fracturing sand production line

Oil fracturing sand has high compressive strength and is mainly used for downhole support in oil fields to increase oil and natural gas production, and is an environmentally friendly product. The product has the advantages of high compressive strength, low density, good sphericity, high smoothness and strong flow conductivity.

The specifications of petroleum fracturing sand products are: 20-40 mesh, 40-70 mesh, 70-140 mesh. In the field of petroleum, fracturing refers to a method of using hydraulic action to form cracks in oil and gas layers during the process of oil or gas production, also known as hydraulic fracturing.

The overall fracturing sand production line is divided into five working stages, namely the raw material mining stage, the raw material drying and pre-screening stage, the raw material washing stage, and the concentrate drying stage. It can solve the problems of fracturing sand classification, washing, tail water purification, solid waste dry discharge, etc. The finished product can achieve round sand particle size and higher compression value. The entire production line has large output, high efficiency, stable operation, and equipment can be configured according to customer conditions.

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.
