The Airblast AFC Garnet Recycler effortlessly regrades garnet and other abrasives, typically recovered from on-site blasting operations. The unit eliminates contamination, both oversize and undersized, before re-sieving to ensure abrasives are in the best condition prior to being recycled through the blast machine.
Following the blasting process, abrasive becomes laden with particles of the removed coating, corrosion particles, spent abrasive, large contaminants and dust. This mixture is delivered to the elevator hopper and elevated to the sieve and air wash separator. In this section any remaining dust is taken to the dust collector located in the Airjet unit and spent abrasive and large contaminants are delivered to a collection bin.
This method of separating spent abrasive ensures that it is not delivered to the dust collector, which prevents the cartridge filters within from suffering premature wear. The operator may adjust the power of the vacuum placed on the abrasive in order to determine the minimum size of particle that should remain in the system (the higher the vacuum the larger the particle taken out of the abrasive).
Clean abrasive is now all that remains, which is deposited in a storage hopper equal in capacity to the volume of the blast machine(s). Once all the abrasive in the blast machine has been delivered, or at any other time the operator releases the dead mans handle, the blast machine is automatically charged with fresh abrasive from the hopper above.
The whole unit is skid mounted and is designed to be mobile.
