Surface International manufacture Plate Cleaning Shot Blasting Machine. The Plate Cleaning Shot Blasting Machine consists of multiple centrifugal blast wheels each of them driven by individual motors to give a thorough cleaning. The jobs kept on suitable conveying system with variable speed drive. The jobs enter the blast cabinet for cleaning from abrasives fired by multi-wheels for homogenous finish. The duly shot blasted components come out from the exit vestibule of the cabinet. These machines are fully equipped with abrasive recovery, abrasive cleaning system, dust collector, control panel and manganese lining.
The Blast Cabinet is lined with High Manganese rolled plate tiles in overlap style for adequate protection of the base plates. The Perforated High Manganese Casted Sheet is placed above Screw Conveyor line for protection purpose. Rubber Curtains are provided in the inlet and outlet Vestibules to stop escaping Abrasives. The Roller inside Blast Cabinet is lined with replaceable High Manganese Steel sleeves.
The Service Door is provided in Blast Cabinet with Safety features. A Sensor is provided at Vestibules to start the Blast Cycle, when the job reaches the blasting zone. This saves power as well as wear & tear on the blast cabinet interiors when the sheet is not in the blast cabinet. If the sheets or blast components are not fed into the machine for some reason the solenoid valve controlling flow of shots stop abrasive feed to avoid wear & tear of blast cabinet & the machine comes to power saving mode. The Blast Wheel 4 Nos. / 6 Nos./8 Nos. are fitted on Blast Cabinet to cover Shot Blasting of Plates. A suitable capacity of Bucket Elevator is provided for transferring Shots to Rotary Screen Separator.
