Abrasive Storage

Holding abrasive cleaner
Correct storage of abrasives can prolong the life and reduce waste of abrasive. When abrasives are purchased by the tonne, every kilogram or more lost through poor storage and handling will affect the cost of a project.

Basic rules for storage of abrasive

All types of abrasives must be kept clean and dry and, where possible, in the original factory packaging, unopened until ready for use. Moisture is the biggest enemy, which can cause clumping in abrasives such as garnet and bicarb soda. Steel grit and steel shot do not fare well when moisture is added; these abrasives will rust together into clumps making the material useless.

Careful storage also reduces injuries. Split bags of glass beads or steel shot can be a hazard underfoot. Spills should be cleaned up immediately.

Storage prior to use.

Storage hoppers can also be used as a loading facility for the blasting process. When placed above the blast pot, it can be used to decant directly into the vessel, reducing manhandling. New abrasive can be stored, or the hopper may form part of a recycling system. Capacities of the hoppers are unlimited, as the illustrations below show. Loading options are available, from basic fork lifting to vacuum systems to elevators.

Abrasive storage and pot loading options.
  • Allows reduced manhandling of the product, reducing injuries
  • Allows ease of refilling blast vessels, decreasing down time between operations
  • As most hoppers are located over the blasting vessel, the extra space required is negligible
  • Very low maintenance required
  • Options such as level sensors, levelling screws, access ladders and platforms may be installed
  • Suitable for all types of abrasives
