Pink Fused Alumina for Making Abrasive Papers
- Product Introduction
Products Description
Chromium corundum is made of alumina powder and moderate chromium oxide ,which is melted at high temperature.
Chromium fused alumina is pink,its hardness is similar to white alumina,and toughness is higher than white alumina.Abrasives made of chromium fused alumina have good durability and high smoothness of grinding.
It is suitable for precision grinding such as measuring instruments,machine tool shafts,instrument parts,screwwork parts and sample grinding.It can also be used as grinding and polishing materials,precision casting sand,spraying materials,chemical catalyst carriers,special ceramics,high-grade refractories,etc.
Carefully selected material
Using advanced screening and grading technology,our experienced workers select high-quality raw material carefully,thus ensure each batch of product is in good quality.
Strict production process
1Raw material→2pyrolytic smelting→3cooling out of furnace→4mass crashing→5ball grinding→6Barmack crushing and sieving→7finished product of granular sand →8sifting residue powder→9chemical treatment→10water countercurrent classification→11sediment pool→12drying fine powder→13inspection of finished product→14finished product storage→15reinspection→16shipment

A complete range of specifications
secion sand 0-1mm/1-3mm/3-5mm/5-8mm
granular sand:16#/24#/30#/36#/46#/60#/80#
fine powder100#/200#/325#/400#
Other sizes are also available on request.
Wide range in application
The chromium fused alumina produced by our company can also be used in the production of coated abrasives industry,mainly for wood grinding,also can be used for non-ferrous metal grinding,such as copper,brass,etc.Compared with white corundum,chromium fused alumina is more unbreakable,so it forms a smooth surface.
