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#
Refractory Grit size:1-0mm, 3-1mm, 5-3mm, 5-8mm, -200mesh, -240mesh, -320mesh.
