Product Description

 Flap Wheel Brown Aluminium Oxide Blasting Abrasive For Bonded / Sandpaper
 

Brown aluminum oxide is obtained from fusion of high-quality bauxite. Main features are Good harness, high compression strength, good hydrophily and lower expansion coefficient.There are F sand and P sand.The F grits 12#-220# is widely used to produce Bonded abrasives grinding wheel, cutting discs, also for sandblasting.P sand used to produce coating abrasives sand paper, sand belt, flap wheel, etc.

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.

Grit size: 16#, 20#, 24#, 30#, 36#, 46#, 54#, 60#, 80#, 100#, 120#, 150#, 180#, 220#
Micropowder: 240#, 280#, 320#, 360#, 400#, 500#, 600#, 800#, 1000#, 1200#, 1500#,  2000#
