Inert ceramic balls

Alumina Ball products in the chemical industry has a wide range of applications, especially for large enterprises, alumina ball of purchase is not only not a small investment, and their quality balls for protection, production efficiency of the catalyst, and this will a certain relationship. So the quality of balls must meet the requirements of the use of units to the company's product quality standards, for example, on the common quality standards for industrial balls will be explained. Balls www.pxsbaixing.com/ diameter: its diameter alumina balls divided into 12 kinds of specifications, namely 3,6,8,10,13,20,25,30,38,50,60mm like. According to the national standard diameter balls 3-10mm industry acceptance tolerance of plus or minus 1mm, 13-25mm balls acceptance tolerance should be within 1.5mm. General tolerances 30 balls or more in diameter and must be controlled within 2mm. For the diameter of demanding manufacturers, can be achieved by screening time by precisely controlling sieve diameter balls. The appearance quality alumina ball using conventional measuring and visual inspection. Crushing strength: the choice of having sufficient pressure, force measurement accuracy of the testing machine level, take five balls as a sample. The samples were placed in the test machine platens middle, between the sample and the upper and lower plate pad with 1 ~ 2mm of absorbing paper, smooth evenly with 5 ~ 20mm / min or 0.5 ~ 3.5KN / min load speed reading test pressure sample destroyed, and calculate the arithmetic mean as the final test results. Balls www.jxsbaixing.com/ 1, inert balls product overview inert alumina ball (inert ceramic balls) is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as the reactor catalyst support material covering and tower packing. It has a high temperature high pressure, low water absorption, chemical stability characteristics. Can withstand acid, alkali and other corrosive organic solvents and can withstand the production process the temperature change. Its main role is to increase the gas or liquid distribution points, support and protect the strength is not high activity catalyst. Products on the market, all users are reflected in its performance results comparable with imported products, some technical indicators even higher than similar foreign products. 2, material: feldspar, feldspar - mullite, mullite, mullite - corundum, corundum 3, Chemical composition: feldspar containing Al2O3: 20-30%; feldspar - mullite containing Al2O3: 30-45%; mullite containing Al2O3: 45-70%; mullite - corundum containing Al2O3: 70-90%; corundum containing Al2O3≥90%; Al2O3 + SiO2 ≥90%; Fe2O3≤1%
