The blast cabinet is constructed of 1/2-inch plate steel. A removable safety screen protects the abrasive system from oversize contaminants. The doors are gasketed to provide a positive seal during operation. A pneumatically controlled latch locks the door “CLOSED” during the blast cycle. Cabinet is lined with 1/2” thick cast alloy plates, in line with blast stream and manganese alloy on the other walls. The doors are made of manganese alloy.
5, VK PowerMax 1500, 20 horsepower, 15 inch diameter center-fed direct drive blast wheels lined with 1 inch thick cast chrome/moly perimeter planes and manganese steel front and back wear plates. Wheel
components are dynamically balanced and matched to assure smooth operation. An adjustable pneumatic abrasive-metering valve controls the abrasive flow to the blast wheels.
Parts loading access is achieved by 2 swing open hinge doors exposing the entirety of the blast chamber.
Abrasive leakage is minimized with a positive gasket seal. The workload is supported on a 120 inch diameter steel table rotated by a 2 horsepower drive motor at 1-4 R.P.M variable The table and abrasive resistant liner have slotted openings to drain abrasive into the recovery system. An initial abrasive charge of 7400 pounds
will be required.
The air wash separation system consists of a 2 HP horizontal abrasive auger to feed abrasive into a vertical bucket elevator. The 5 HP vertical abrasive elevator delivers the abrasive shot into an adjustable 20-inch
single lip separator. The cleaned abrasive is then deposited into the abrasive hopper for re-use. A refuse
tube carries separated contaminants to a customer supplied trash container.
