Abstract

An abrasive mix for an abrasive wheel has the composition: ..Pounds .No. 24 grit size aluminium oxide .abrasive . . . . . .5.90 .Powdered phenol formaldehyde resin .1.70 .Natural cryolite powder . . . .1.37 .Lime . . . . . . .0.12 .Carbon black . . . . . .0.04 ..Cubic centimeters .Furfural . . . .25 .Anthracene oil fractions .from coal tar . . .25 The abrasive is placed in a pan and mixing is started, whereupon the furfural is added. When all the abrasive is wet, a mixture of cryolite, lime, carbon black and resin is added and mix ing continued. The anthracene oil is added to lay the dust. The cryolite improves the con sistency of the mix. The carbon black makes the wheel uniformly black. The lime absorbs any water which may be liberated. Specification 695,692, [Group VIII], is referred to.
