Description

Technical Parameters

Product Introduction

Alumina grinding media balls is an excellent desiccant for drying a wide variety of liquids and gases. Our activated alumina has been developed with high attrition resistance and crush strength, It has larger water adsorption capacity comparing to molecular sieve at high relative humidity and providing long service life with performance at or below dew point specifications.

Alumina grinding media balls is widely used in large and small dryers. It is appropriate for use in dehydrating gases in both thermally regenerative and pressure swing adsorption (PSA) process.

Features

1. High strength, excellent wear resistance, 20 times more than commonly ceramic ball of France or ceramic ball, keep the material high degree of purity.

2. High density, high grinding efficiency, shorten 50% grinding times.

3. Very good roundness, very smooth and shiny surface, longer using life.

Advantages

Compared with natural stone balls and normal ceramic balls, alumina grinding ball

increases by 20-40 times in its performance of wear resistance.

Its grinding efficiency improves by 40%-60% and ball mill efficiency add by 30%-40%.

Their total costs only take 40-60 percent of that of natural stone balls.
