1. Check whether it is activated alumina ball color, yellow; 2. See if the service life exceeds two years, if it exceeds two years, replace it as soon as possible; 3. It depends on whether the humidity of the processing air is too high, such as the humidity on the footnote is too high, and
1. Act as a catalyst Inert alumina balls are widely used in fertilizer, petrochemical and other industries as catalysts and catalyst carriers. In addition to specific surface area and surface activity, the selection criteria of the carrier also include many other indicators, including mechanical strength, chemical stability and different selectivity. 2. Defluoridation performance Due to
Alumina ceramic ball production process 1. Preparation of blanks The main components of Dehua’s ceramic blanks are quartz, feldspar and kaolin. According to the molding method of its products, it can be divided into moldable blanks and grouting blanks. 2. Moulding, 3. Forming. Forming is to use a dry plaster mold to make the prepared
Factors affecting the adsorption of alumina balls 1. The influence of arsenic: Activated alumina has the effect of adsorbing arsenic in water. The accumulation of arsenic on the activated alumina spheres leads to a decrease in the adsorption capacity of fluoride ions, making it difficult to elute arsenic ions during regeneration. 2. Raw water alkalinity:
After three years of use, we want to replace it, and then can it be used again? If it can’t be used, why? 1. If the catalyst is replaced after three years of trial use, we recommend that the inert ceramic balls be replaced at the same time, especially in the heavy corrosion industry, and
Alumina balls are also called high-alumina balls, filled ball lights. High-alumina balls are widely used in different types of ceramics, enamels, glass, and chemicals due to their excellent characteristics such as high strength, high hardness, high wear resistance, high specific gravity, small size, high temperature resistance, corrosion resistance, and non-polluting. And so on the thick
Alumina ball detection method Diameter size detection and measurement: use a vernier caliper to measure the average value from different angles. The maximum allowable range of dimensional deviation is within ±3mm, and it is judged to be a qualified product. Visual inspection: no obvious dents, cracks, etc. were found, and all were qualified. Water absorption
Inert alumina ball is abbreviated as inert porcelain ball. It is processed from high-quality chemical porcelain clay materials and has the characteristics of high strength, high chemical stability and thermal stability. So what are the differences between inert ceramic balls and activated alumina balls? Let’s briefly understand: Inert ceramic balls can withstand high temperature, high
At present, ceramic balls and alumina balls are mainly used for grinding in the market because of its low price. At least use zirconium balls, steel balls, and alumina grinding balls. This should be considered based on the properties of the materials, electricity costs, and grinding efficiency. Zirconium ball density 6.0g/cm³ The density of steel
Because of its excellent wear resistance, corrosion resistance, high mechanical strength, high grinding efficiency and other characteristics, alumina balls in the grinding media of the cement industry are widely used in the preparation of blanks and glazes in the ceramic industry and in electronics, chemicals, metallurgy, coal mines, etc. Industry’s ultra-fine powder production. Wear resistance
Alumina lining bricks products have the characteristics of high hardness, high density, low abrasion, good regularity, and corrosion resistance. Alumina bricks are used for wear-resistant linings of ball mills.
