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.
