3 tips to help you get the best results when recycling abrasive


One of the first places blasters look to save on abrasive costs is by collecting and reusing their spent abrasive. But how can you make sure you're getting the best performance out of the recycled blasting media?

3 tips for recycling garnet to achieve the best results

1. Keep the abrasive dry.
Wet abrasive won't recycle.

2. Recycle in batches.
Unless you have a recovery system which automatically collects the spent abrasive and recycles it, it is far more efficient to recycle several tons at once.

3. Remove all the dust.
If any significant amount of dust remains in your recycled abrasive it can cause many problems the next time you blast with it.

Why is dust a big issue?

Blasting with dust creates more dust, which decreases jobsite visibility, therefore lowering production.

Dust also wears your equipment—metering valves, blast hoses and blast nozzles—far quicker than abrasive will. Dust particles are much finer and more plentiful than normal abrasive particles. Small dust particles moving at high speed wears down equipment much faster because of the sheer number of particles.

Dusty abrasive also wastes compressed air. To get the highest productivity when blasting, you need to ensure you’re getting the maximum velocity of abrasive out of the nozzle. To do this, every particle of abrasive needs to be acted upon by compressed air. Dust particles in your abrasive use up compressed air that would otherwise be working on the abrasive particles, resulting in wasted energy and longer production times.

An effective way to remove the dust from your abrasive is to use an abrasive recycler with an air-wash.
