An adjustable timer controls the cycle time. Solenoid valves introduce jets of high-pressure air into the cartridges in turn, through the Venturi opening above each cartridge. The resulting reverse airflow cleans the filter cartridges. Dust removed from the filter surface settles into the hopper. As each pair of filter cartridges is cleaned in succession, the remaining stay.
The used abrasive moves to the abrasive hopper and then the elevator. From the elevator it moves to the rotary sieve, with holes Ø 4, 5 and 6mm at choice. If the abrasive is polluted with big parts like coating scale, woodchips, glass, etc., these contaminants are separated through the rotating movement of the sieve. The sieve is supplied complete with a dust exhaust connection. After the sieve, the abrasive flow is through a cascade system.
The air wash action can be regulated to control the size of the reusable abrasive. Dust and non-usable (too fine) abrasive is automatically discharged and collected in builder’s bags or extracted by the separate filter. The cleaned abrasive will fall into the abrasive silo and is ready to be stored in builder’s bags or blast vessels.
The system is supplied complete with: crane hooks, inspection covers. and flexible dust-exhaust ducting to the builder’s bags.
