Shot Blasting Machines

Shot blasting is a process of Cleaning & Finishing of Castings, Forgings, Aluminium & Zinc die castings, Brass & Gunmetal parts, Sheet metal components, as well as the Tempered or hardened components. These Shot blasting machines are available in Tumblast, Table, Hanger, as well as the latest Continuous conveyor models.



In Tumblast, a conveyor belt rotates inwards, inside the chamber of the shot blasting machine & the components are loaded on it as per the size & capacity of the machine. The door is then closed. The Rotor is switched on for throwing Shots or Grits on the components. By this process, the loaded components get a universal finish. Abrasive media such as Shots or Grits are continuously fed by the elevator of abrasive media. All the dust extracted in the process goes to the attached dust collector. On completion of the desired time period, the door is opened & then the conveyor belt is driven outwards. As a result, the components can be removed from the chamber. An automatic loading system can also be attached to the shot/grit blasting machine. The Tumblast shot/grit blasting machines are available in many sizes, right from a 2 cu ft capacity machine to a 15 & 20 cu ft capacity machines. Some of the sizes are: 20" x 27", 20" x 42", 27" x 36", 30" x 43", 36" x 42", 42" x 42" as well 48" x 48" & the bigger ones.

Similarly, Hanger model Shot blasting machines are available in Single / Double door type, Centralised hanger type as well a monorail type. In this model, the components are hanged instead of loading on the conveyor belt. Rest of the process is same. The hanger rotates for a universal finish using multiple rotors depending upon the requirement. The benefit is that the components do not touch each other in the process of finishing and hence are scratch free. Swing table model shot blasting machines are suitable for bigger or heavier components or if the smaller parts are to be shot blasted only one side. Many sizes are available from a minimum 36" of the table model to 120" of the table model in single as well double doors.
Continuous conveyor model shot blasting machines are suitable for smaller components which are to be shot blasted only one side with a single rotor. Multiple sides can be finished by using multiple rotors. Components are fed from one side & removed from the other side duly finished. The spare parts mostly wearable are made from ni-hard or alloy steel to get the maximum life.The main spare parts include the Rotor, Blades, Spring locks, Cage & Impeller, Cage adapter, center plate, Top segment, Sideliners, Round plates as well the conveyor belt. Few precautions are necessary while running the machine.

Table model is used for the bigger & heavier components for the top side shot blasting with a single rotor or upper side shot blasting with multiple rotors. For the smaller parts that are to be shot blasted only from the upper side only, consumers are now using the Continuous conveyor model as it is must faster and cost-effective.
The Tumblast model of Shot blasting machine if to be used for finishing of smaller to medium-sized components is best suitable and very cost effective. we can be contacted with details of your components for a suitable size & model of shot blasting machine. More details can be viewed on http://www.finishingmachines.com
