Buebendorf Brothers alumina balls and alumina bricks
 

A lot has changed since 1905, but Buebendorf Brothers  quality products and dependable service remain constant.

As we start our second century of supplying industrial minerals to users world wide, we are pleased to announce the introduction of a new line of high density grinding media and lining brick for ball and pebble mills.

High density alumina grinding media has proven itself to be the best choice for both dry and wet milling. Their higher specific gravity results in high productivity and better wear resistance. Our high density alumina media, with an alumina content of 87% and Rockwell hardness of 90, delivers consistent, predictable, dependable results batch after batch.

In those applications involving high heat buildup and quenching, our high density alumina does not fracture or spauld, eliminating costly batch contamination and down time.

The apparent density of 3.45  of  high density alumina grinding media provides quick grind time, and higher batch capacities than some other types of grinding media. In addition, it also allows for lower mill speeds, which translate into less  electrical  usage and lower utility (electric) bills, an important consideration n today’s environment of rising energy costs.

High density alumina grinding media is ball shaped and available in 30, 40, 50, and 60 mm sizes to meet a wide range of milling needs. Also available is a 20 mm satellite or banded ball shapes.

High density alumina lining brick, also know as block, is made of the same material and to the same specifications as the high density alumina grinding media. Their superior wear resistance allows thinner brick to be used while still providing long term durability. The use of thinner high density brick for lining the mill allows for larger batches, increasing productivity.

100 years of providing our customers with the finest in product and service provides you the assurance that we have the experience to meet your needs in a timely, professional manner.
