Tumblast Blasting Machine


The proposed Tumblast Blasting Machine shall be employed for cleaning of entire external surface area of casting, forging or fabricated components. The machine shall be useful for shot blasting.


The Blast cabinet is fabricated from 6 mm & 10 mm thick Mild Steel plates with structural steel reinforcement for robust construction. Interior portion of cabinet is lined with wear resistant SLL roof liners, wear resistant SLL Barrel Head Seals & wear resistant SLL Barrel Head Liners. Bottom Discharge hopper is in-built with cabinet. Hopper discharges spent abrasive directly to Elevator Boot Section through elevator driven lower screw. Cabinet is provided with an inspection door for easy access to interior. Slide type pneumatically smooth operated leak proof door is provided is front of cabinet having intermeshing labyrinth seal to prevent leakage of rebounding abrasive.


The work Conveyor is vulcanized endless rubber belt multiple ply construction running on support rollers placed to give required configuration easy tumbling of jobs. The front idler roller is equipped with fins designed to prevent abrasive from building up under roll. The support rollers are in sealed flange type ball bearings. The take-up and adjustment of belt tracking is accomplished through bolt type, movable bearing mounts located on cabinet walls. It has uniform and closed perforation ¼” 5/16” / 3/8” sizes holes (if required), filtering the abrasive into the bottom hopper.


The unit is enclosed by an easily detachable Mild Steel fabricated guard housing, equipped with replaceable wear resistant liners plate. The drive shaft is mounted in anti-friction bearings contained sealed unit type housing featuring a visible oil level indicator gauge.


Spent abrasive falls through the perforated rubber belt work conveyor and drop into gravity hopper below the cabinet to elevator driven lower screw, connected with a bucket elevator. A hopper screen is provided to separate foreign material from the abrasive system. Bucket elevator carries & delivers abrasive into and overheads air wash separator and storage hopper.
