Standard Features:
|
Abrasive
Storage Hopper with a Caged Ladder
|
|
| The storage hopper is a free-standing hopper which is reinforced with structual steel. The hopper positions above the blast tank assemblies to provide easy access to the blast tanks tanks for maintenance. A caged ladder and handrail assembly is standard on all storage hoppers to allow access to the air-wash separator which is positioned on top of the storage hopper. |  |
|
Blast
Tank Assemblies:
|
|
 |
Blast tanks are positioned directly under the abrasive storage hopper and are gravity fed. A covered riser assembly filters the abrasive through a perforated plate screen and contains the abrasive when the tanks exhause, preventing abrasive leakage that may collect in the area |
|
Air-Wash
Separator/Classifier:
|
|
| The heart of the abrasive reclaim system is Hoffman Blast Room's air-wash separator. The separator removes contaminants from the abrasive mix, and the air-wash classifies the abrasive to maintain a constant size. This separator can classify all types of dry ferrous and non-ferrous abrasives. |  |
|
Elevator:
|
|
|
|
The elevator assembly is constructed of mild steel with angle irn reinforcements. Malleable iron buckets bolted to a heavy-duty belt convey the abrasive material to the air-wash separator. A one piece cast iron pully, which has been crowned for tracking and rubber lagged to prevent slippage, are located in the boot and head section of the elevator to drive the belt. The belt is easily adjusted from the head section to provide exact tracking. |
|
Screws:
|
|
| The reclaim floors utilize a heavy-duty screw to return the abrasive to the separator/classification system. The standard screw is 9" in diameter, which consists of a 5" diameter schedule 40 pipe wrapped with 1/4" thich flighting on a 2/3 pitch. |  |
|
Metering
Shed Plates:
|
|
 |
Shed plates are added to all partial reclaim floor designs to meter the amount of abrasive being fed into the screw reclaim system. The metering shed plates eliminate overloading of the reclaim floor. The shed plates are easily adjusted for various types of abrasives. |
