Product Description

High Hardness BrownFused Alumina Blast Media P12 - P220 Grit For Sand Belts

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.
 

Brown aluminum oxide F grit for bonded abrasives and P grit for coated abrasives according to different usage;

Top Grade (Min95% Al₂O₃),off grade(Min90% Al₂O₃),second grade(Min80% Al₂O₃) according to different

Fixed Furnace and Tilting Furnace according to different furnace types.

Ball milling, crusher, barmac brown aluminum oxide according to different curshing methods.
 

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.

Brown Aluminum Oxide Application in making coated abrasives

 

Brown Aluminum Oxide P60,P70,P90,P100 is widely used for making coated abrasives such as

Jumbo rolls,sand paper to polishing the stainless still tablewares,wood furniture, rattan, crafts etc.

 

In addition,Brown Aluminum Oxide is also used for the following applications:

Bonded Abrasives such as resin cutting discs,grinding wheels for cutting or grinding the the carbon steel,

oridiary alloy steel, calcinable cast iron, hard bronze, etc

Blasting media for oxide scale removal, rust removal,etching,engraving,surface prepation, mold cleaning etc.

Refractiories for making high alumina brick, castables,furnace lining etc.

Anti-skid material for highways,aircraft runway, parking area etc.
