Product Description

 F24 F30 F36 blasting brown fused alumina corundum abrasives for sand blasting

Brown Fused Alumina, also called Brown aluminum oxide, is the main raw materials to produce vitrified bonded abrasives and resin bonded abrasives like cutting discs, cutting wheels, grinding wheels, etc..

Grit sizes from 12#-220#. Popular sizes 24#,30#,36#,46#,60#, 80# etc.

All grains can meet GB/T2481.2-2009 and/or FEPA 42-1:2006.

 

By Al2O3:

• 95% Al2O3 Grade A Brown aluminum oxide
• 92% Al2O3 Offset A Brown aluminum oxide
• 85% Al2O3 Grade B Brown aluminum oxide

By application:

• F sand for Bonded Abrasives
• P sand for coated Abrasives

By smelting type:

• Tilting furnace
• Fixed Furnace

By crushing type:

• Barmac
• Rolling
• Ball milling

By Additional treatment:

• Middle temperature calcined Brown aluminum oxide,
• High temperature calcined Brown aluminum oxide,
• Coated Brown aluminum oxide
• High temperature calcined & coated Brown aluminum oxide (AHMCF)

 

What Is Difference Between Tilting Furnace Melted BFA & Fixing Furnace Melted BFA ?
Ball Milling & Barmac Process?
 

1. Tilting furnace process affects SiO2, SiO2 <1% by Tilting furnace, SiO2 <1.5% is by fixed furnace.

2. Barmac affects the density, the grain shape is  rounder & the density is greater than ball milling

3. The Tilting furnace made BFA has high Al2O3 content

4. The corundum has good toughness & more suitable for abrasive products by dumping furnace process
 

The difference between F-grit & P-grit Abrasive grains:

F-grit is more suitable for bonded abrasive tools.

P-grit is more suitable for coated abrasive tools. It is with a closer tolerance size distribution, lower density, and better self-sharpening ability than non-P-grit abrasives, which means that they offer a more consistent surface finish.
