|Three alternatives for the recovery of abrasive at the blast room floors:
Blind floor and manual recovery:
The floor is flat and features a sweep pit with under floor hopper, the abrasive is pushed into the pit manually. Once in the hopper the system automatically screens, cleans and reloads the abrasive. This equipment is the economical alternative.
Blind floor with central pipe and manual recovery:
Flat floor with a central gutter where the abrasive is pushed manually. Once in the gutter, the system automatically screens, cleans and reloads the abrasive. It reduces the abrasive recovery time, without considerably increasing the installation cost.
Automatic recovery floor:
A reclaim system, completely covered with grids over the entire floor area. The system screens, cleans and reloads the abrasive trough pneumatic sweepers.
Track-guides mounted at the sweeping trays joint. Avoids reclamation dead time, and considerably reduces operation costs. Low electric-power consumption and low maintenance needs.
|During blasting jobs in closed rooms, it is essential to have a remote control system -“Dead man”-, which allows the full control of blasting at the hose end, where the operator holds the nozzle. Automatic shut off if the operator drops the handle. Shut-off is pneumatically operated through a deviation of the compressed air feeder. It does not require air consumption during working periods.
