Hanger type shot blast machines designed and built as fully integrated blast cleaning systems to handle large/small or more fragile castings than barrel/table type machines. They provide a cost effective solution for batch cleaning.     Hanger type Machine consists of horizontal door with a rotating hanger type work/job handling system. This hanger is directly mounted on the door of the machine and it rotates on its own axis, drive unit of this hanger is provided outside the door. This hanger swings out as the door is opened, making the full area easily approachable for loading and unloading of the components. For loading the components, door of the machine is opened manually & components to be blasted are hanged one by one on to the door hanger and the door of the machine is closed.     After this two no’s of Blast wheel units which are strategically placed on the Blast cabinet, is started. Blast wheels will fire the abrasive at high velocity on the components hanged on the hangers and rotating in clockwise and Anti-clockwise direction and blast cleans them thoroughly. Bi-directional rotational mechanism of hanger ensures that each and every portion of the component will get exposed to the blast stream for through cleaning. The arrangement of the blast wheel ensures optimum blast cleaning and maximum utilisation of the abrasive energy. After the required blasting cycle, blast wheel unit shuts off and door of the machine is opened manually for unloading of the components.

Machine consists of : Blast cabinet / Mn. Steel Lining Inside cabinet / Heavy Duty Blast Wheels/ Abrasive Recycling and recirculation system/ Automatic Abrasive Control Mechanism/ Inlet & Outlet side Tyre type Skew rollers/ Dust Collector

Close Loop Hanger Type SBM consists of a close-loop conveyor system which consists of numbers of chain-driven trolleys with fixtures to hold the hangers. The components or pieces which are to be shot blasted are placed on these hanger and one ny one taken inside the blast chamber for blasting by the chain-driven machanism system.

  The roller conveyor shot blasting machine is best suitable for the shot blasting of Round steel Pipes..etc. It consists of inlet and outlet side Roller conveyors as material handling systems. The components to be blasted are placed on inlet side of the roller conveyor, from where it travels forward and enters into the inlet tunnel. After passing through the inlet tunnel components enters into the blast zone which consists of 4 no’s of Blast Wheels. All these Blast wheel units are strategically placed around the Blast cabinet. The arrangement of the blast wheel ensures optimum blast cleaning and maximum utilization of the abrasive energy. Blast wheels fires the abrasive at high velocity on the forward moving components & blast cleans them thoroughly. Blasted material moves forward and enters into the outlet tunnel. The spent abrasive from blasting operation after passing through the perforated floor plates will get collected into the cabinet’s bottom storage hopper. From where it is transferred to the bucket elevator, which elevate the abrasive vertically and discharges the same into a media separation unit where dust and fine abrasives are cleaned ensuring that only clean abrasive will re-circulate to the blast wheel units for effective and better cleaning. A Dust collection system is provided with the machine which will continuously remove the dust and fine particles, thus keeping the inside of the machine and the nearby environment dust & pollution free.
