Grit blasting machine is mainly used to eliminate foreign particles from the metal surface. Grit blasting is a particle size sand process, also known as sand blasting. It is a process in which abrasives are sprayed out at very high pressure through nozzle using compressed air on the surface which needs to be re-engineered. This results in providing a desirable surface finish. Grit blasting machine can also enhance the surface of components by removing scratches, casting and mould marks. The operation of grit blasting machine depends on the application. The main operations take places in grit blasting machine are:
A grit blasting machine consists of two hoses, one of which is connected to the bottom of the handle and other one is connected with the lower side of the barrel.it has repository of loose sand which help in forming a vessel or bucket. When the gun is fired, the air creates suction which pulls the sand into gun and this sand can be reused.
Grit blasting machines can be categorized as:-
Grit blasting machines are mostly suitable for preparing the surface before welding and afterwards to enhance the adhesion of coatings. Moreover, grit blasting can be used to remove sand and scale formed in the fettling of castings. Due to the effect of compression in grit blasting machine, it can be used to prevent corrosion also.
Grit blasting cabinet is used where no dust is needed to create in the working environment. The component which is treated is inserted into the cabinet and sealed until the pressurized abrasive is forced through nozzles into the chamber. Grit blasting machine can be operated with the help of foot-pedal by the operator. It can be turn on and off with the foot-pedal and rubber glove hand inserts operators to pick the components up and move them around as they are being blasted. The operator works inside the blasting room, wearing operator’s suit. Grit blasting machine supplies effective services and solution for many manufacturing industries based on their demands.
