How to slove the wear of the impeller?

 




The materials in the sand washing machine have been crushed in various ways from granular to powdery with different meshes: the lining plate mainly accepts the force of the impeller, and the wear mode is mainly the conflict between each other, so the surface Both hardness and toughness have certain requirements; the guard plate is mainly due to the friction and wear of material activities, and the demand for impact is not high; all accessories are also subject to corrosion and wear. The impeller exists in the movement of the fine sand recovery machine, and the parabola formed by the falling down crushes the material; the conflict between the impeller and the material, the material and the material, the material and the liner; the mutual crushing caused by the free fall of the material.


It can be seen from this that there are many ways of wearing the wearing parts in the sand washing machine. The impeller is mainly caused by falling and friction wear, so there is also a demand for out-of-roundness of the impeller in addition to wear resistance; Different needs do not necessarily require the same raw materials. Appropriate materials should be selected according to different operating conditions to achieve economical and practical purposes under the premise of meeting the needs.

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.

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.

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.
