Abstract
Blasting abrasives comprise a plurality of particles. Blasting abrasives are classified into two basic types with many varieties of particles within these categories. Sharp, angular, and blocky abrasives and bead and/or rounded abrasives. Blasting abrasives are describe that are made from mixing particles of sharp, angular or blocky abrasives with bead or round abrasives. The blasting performance of any sharp, angular, or blocky abrasive may be improved by combining it with the bead or round abrasives in concentrations from 0.1 wt. % to 50 wt. %.
Claims60
A blasting abrasive, comprising:
- an SAB abrasive, and
- a bead abrasive, wherein the bead abrasive is less than 70 wt. % of the weight of the blasting abrasive.
A method of preparing a blasting abrasive, comprising:
- blending a bead abrasive with an SAB abrasive, wherein a concentration of bead abrasive bead abrasive in the blasting abrasive is less than a concentration of SAB abrasive in the blasting abrasive.
A method for preparing a blasting abrasive, comprising:
- providing an amount of crushed glass abrasive,
- adding an amount of glass bead abrasive such that the concentration of bead abrasive in the blasting abrasive is between 0.1 wt. % and 50 wt. %;
- and
- mixing the crushed glass abrasive and the glass bead abrasive.
A blasting abrasive, comprising:
- a first abrasive component, wherein the first abrasive component alone has a first void space, and
- a second abrasive component, wherein the second blasting abrasive component has a second void space and the second void space is lower than the first void space.
A method for preparing a blasting abrasive for abrasive blasting comprising:
- charging a blast pot with at least one SAB abrasive;
- charging the blast pot with at least one bead abrasive, wherein the at least one bead abrasive is between 0.1 wt. % and 50 wt. % of a total amount of blasting abrasive charged to the blast pot;
- and
- blasting the abrasive mixture.
A blasting abrasive, comprising:
- a non-vitreous mineral abrasive;
- and
- a glass abrasive wherein the glass abrasive is a bead abrasive and in a concentration in a range of 0.1 wt. % to 50 wt. %.
The blasting abrasive of claim 29, wherein the glass abrasive is in a concentration in a range of 0.1 wt. % to 20 wt. %.

- and
- glass bead having a particle size between sieve size 40 and sieve size 70.
A blasting abrasive, comprising:
- a mineral slag SAB abrasive;
- and
- a bead abrasive, wherein the bead abrasive is in a concentration range of 0.1 wt. % to 20 wt. %.
A blasting abrasive, comprising:
- a coal slag abrasive;
- and
- a bead abrasive, wherein the glass abrasive is a bead abrasive and in a concentration in a range of 0.1 wt. % to 50 wt. %.
A mineral slag blasting abrasive, comprising:
- at least one mineral slag abrasive, and
- a bead abrasive, wherein the bead abrasive is less than 70 wt. % of the weight of the blasting abrasive.
A naturally occurring minerals and mineral sands blasting abrasive, comprising:
- at least one naturally occurring minerals and mineral sands abrasive, and
- a bead abrasive, wherein the bead abrasive is less than 70 wt. % of the weight of the blasting abrasive.
A crushed glass blasting abrasive, comprising:
- at least one crushed glass abrasive, and
- a bead abrasive, wherein the bead abrasive is less than 70 wt. % of the weight of the blasting abrasive.
