Product Description
Ksourceep Medium-Alumina Ceramic Ball for Catalyst Alumina Balls
Products introduction:
Medium aluminum balls (medium aluminum ceramic balls) are widely used in ball mill ceramics, petroleum, fine chemicals, building materials, metallurgy, machinery, electronics and many other fields. They have high hardness, high specific gravity, good high temperature performance, high mechanical strength, and no pollution to materials. Good wear resistance and other advantages, it is currently the most expensive grinding body on the market. And in isostatic pressing, aluminum grinding balls can improve the efficiency of ball grinding better than natural pebbles and silicon carbide balls. Under the conditions of rotation speed, material ball, and water ratio, the grinding time can be shortened, the output of a single machine can be increased, and the cost of ball milling can be greatly reduced.
Inert mid -alumina balls have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process.The main role of inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.Application:
They are widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.
