With the advent of the information age, all industries are developing rapidly, presenting both opportunities and challenges. Brown aluminum oxide has been around for less than a century, and brown fused alumina manufacturers have grown from nothing to a production capacity of tens of thousands of tons per year. The brown fused alumina produced varies in quality and specifications, and consequently, in price.
Reasons for the price difference of brown aluminum oxide:
(1) Raw materials
As we all know, bauxite is the main raw material for producing brown fused alumina, so the quality of bauxite is a major factor affecting the quality of brown aluminum oxide. Brown fused alumina produced from high-alumina bauxite is of better quality and naturally has a higher price.
(2) Smelting Furnace
Everyone is familiar with smelting furnaces. The most common methods for smelting brown aluminum oxide are fixed furnaces and tilting furnaces. Products produced by fixed furnaces are lighter in color and have a lower aluminum content than those produced by tilting furnaces, so they are cheaper.
(3) Production Process
The main difference in production process lies in the crushing method of brown fused alumina. There are only three crushing methods: roller mill, ball mill, and Barmac mill. Because the Barmac mill is expensive, the products produced are of high quality, so the price is higher than the products produced by the other two crushing methods.
(4) Particle Size
The price of very fine brown aluminum oxide powder is higher, mainly because it requires repeated sieving and processing, making the process more complex. Generally, pure grade powder is more expensive than graded powder. Graded powders have a larger particle size difference and are easier to sieve during production, thus they are cheaper.
