OUR INDUSTRIAL HARD GRAINS ARE USED IN .....
BONDED ABRASIVES :
e.g. Flour Milling Stones/Atta Chakkies
,, Rice Polisher Stones
,, Pulse/Dal Mills
,, Grinding Wheels
,, Polishing blocks ( e.g. for granite floors)
IN COATED ABRASIVES :
e.g. Emery Paper
,, Sand Paper
,, Buffing cloth Wheels/Flaps
IN REFRACTORIES :
e.g. in the manufacture of Fire Bricks
e.g. in the manufacture of Castable refractory Cement.
(Generally the aluminium oxide used is of low iron,
yet we suggest you use our BAB because
in the case of fines, the free magnetic content gets reduced)
IN PRESSURE BLASTING :
e.g. Shot Blasting & Wet/liquid
,, Dry blasting ( e.g. for ship repair )
FOR METAL FINISHING :
e.g. Polishing / Buffing
IN CONSTRUCTION BUSINESS:
e.g. For non-slip floor/tiles
,, Floor hardeners
,, Cements additives
AS A RAW MATERIAL :
e.g. In cast-iron foundry in small ratio
,, In steel furnaces as flux
