Zirconium sand is a commonly used industrial raw material, widely used in various fields. The process flow of selecting zirconium sand has an important impact on the quality and yield of zirconium sand. This article will introduce the process flow of selecting zirconium sand to help readers understand the production process of selecting zirconium sand.
1、 Mineral processing of zirconium sand
The first step in selecting zirconium sand is the beneficiation of zirconium sand. In zirconium sand, there are different levels of impurities, such as iron, aluminum, titanium, etc., which can affect the quality of zirconium sand. Therefore, it is necessary to beneficiate zirconium sand. There are two methods of mineral processing: physical method and chemical method. The physical method mainly uses methods such as gravity separation, magnetic separation, and flotation for separation, while the chemical law uses chemical reactions for separation.
II. Crushing of zirconium sand
The zirconium sand after beneficiation needs to be crushed for better subsequent treatment. The methods of crushing include mechanical crushing and chemical crushing. Mechanical crushing is the use of mechanical equipment to crush zirconium sand, while chemical crushing is the use of chemical reactions to decompose zirconium sand.
III. Sieving of Zirconium Sand
The crushed zirconium sand needs to be screened to remove particles of different sizes. There are two methods of screening: dry method and wet method. The dry method uses a screening machine for screening, while the wet method uses water for screening.
4、 Washing of zirconium sand
The zirconium sand screened at needs to be washed to remove surface impurities. The methods of washing include mechanical washing and chemical washing. Mechanical washing uses mechanical equipment to wash zirconium sand, while chemical washing uses chemical reactions to remove impurities from the surface of zirconium sand.
5、 Drying of zirconium sand
The washed zirconium sand needs to be dried to remove moisture. There are two methods of drying: natural drying and mechanical drying. Natural drying involves placing zirconium sand in a well ventilated area for drying, while mechanical drying involves using mechanical equipment for drying.
6、 Sintering of zirconium sand
The dried zirconium sand needs to be sintered to improve its thermal stability and corrosion resistance. There are two methods of sintering: oxidation sintering and carbonization sintering. Oxidative sintering involves heating zirconium sand to high temperature and sintering in oxygen, while carbonization sintering involves heating zirconium sand and carbon together and sintering in an inert gas.
7、 Forming of zirconium sand
The sintered zirconium sand needs to be formed in order to produce zirconium sand products of different shapes. There are two methods of molding: compression molding and injection molding. Compression molding involves placing zirconium sand in a mold for compression, while injection molding involves melting zirconium sand and injecting it into the mold for molding.
The above is the process flow for selecting zirconium sand, through which high-quality zirconium sand can be prepared. The process of selecting zirconium sand requires strict control of each step to ensure the quality and yield of zirconium sand.
