Abrasive Components Used in Blasting
Abrasives are a vital ingredient of shot blasting. Silica in form of sand is the commonest of the abrasives used in blasting. However silica being prone to conversion to dust results in health hazards for blast room operators. Commercial varieties of silica used for blasting is often coated with resins to control dust emission. Garnet is a more expensive though safer abrasive as it produces dust in limited quantities.
