Part1. Auto Shot Blasting Machine Knowledge 

1.1. What is the auto shot blasting machine?

Shot blasting is a mechanical surface treatment process. It uses the centrifugal force of the blast turbines of the shot blasting machine during high-speed rotation to project the steel shot at a high speed to the surface of the metal steel, causing collision and blow plays the role of grinding, removing rust and other impurities on the metal surface, and the metal surface produces a certain degree of roughness.  Commonly used shot blasting machine types include tumble belt shot blasting, roller conveyor shot blasting machine, hanger shot blasting machine, floor shot blaster, overhead rail shot blasting machine etc.

1.2. What types of Auto shot blasting machine are commonly used? 

Firstly，i want to say the simple who is also called entry-level auto shot blasting machine. With the features of low cost, simple operation and easy maintenance, this tumble belt shot blasting machine is always favored by users at home and abroad. Tumble belt shot blast machines are the ideal way to clean and finish batches of components such as castings and small fabrications. The transport belt provides the tumbling action to expose all areas of the components to the blast stream, to ensure complete cleaning in one cycle. After the blast cycle, the automatic reversal of the conveyor discharges the components ready for further processing.

Secondly, i will introduce the hanger shot blasting machine. Spinner hanger blasting machine is designed to process heavy and complex shaped work pieces, which are manufactured in smaller or medium series. Work pieces can weight from 1 kg to 50,000 kg or more. Basic spinner hanger is ideal for less demanding users, as it has predefined characteristics and limited options, but despite all these achieves high production quality. Work pieces are mounted individually or in a cluster on a hook and transported in the machine. Transport system is I, Y or circular closed loop conveyor. Work pieces are blasted in a jet of abrasive, which provides efficient treatment of the surface.

Thirdly, i will introduce the roller conveyor shot blasting machine. Roller conveyor shot blasting machine, mainly used for buildings, bridges and other industries with large I-beam H-beam steel structure such as size pieces of high stress and the surface rust. The workpieces crosses the tunnel laid on a roller conveyor, extendible outside with modular lengths. The surface treatment is done during the running through the blasting chamber.

Fourthly, Then i will introduce the rotary table shot blasting machine. Rotary table shot blast machine is used for shot blasting of various part shapes and dimensions, casts and forged parts, pressed parts, steel and non-ferrous metal parts and parts made from fragile materials. The blasting unit does cleans surface, desand casting, consolidate the surface (micro handling), roughing the surface before painting, etc. Rotary table blasting machines are especially suitable for use in small series and individual part production.

Fifthly, i will introduce the wire mesh belt shot blasting machine. Wire mesh belt shot blasting machine is suitable for continuous blasting thin and collision-sensitive die castings, pressure castings, ferrous and non-ferrous castings, forgings, automotive accessories, and weldments. Workpiece weight ranging from 1kg to 100kg. A highly wear-resistant wire mesh belt, with tension adjustment, provides the part transport. Wire mesh belt width has 600mm, 800mm, 1000mm and 1200mm.

Sixthly, i will introduce the pavers shot blasting machine. Pavers shot blasting machine is mainly used for surface roughening treatment of marbles, granites, concrete products, and natural stone. It provides twin advantage foremost subject field end provides outstanding appearance as a result of the rough surface and therefore the exposed aggregates. Second "roughened" surface has excellent non-slip properties.

Seventhly, i will introduce the pipes shot blasting machine. Steel pipe moves through the machine on skew roller conveyors or roller conveyors or tire conveyor. Such form of the conveyor provides simultaneous rotation and transition movement of the pipes through the machine, which can achieve evenly blasted surface.The shot blasting part of the machine’s robust housing is protected by wear-resistant shields made from manganese steel. Entry and exit seals chamber with a series of rubber screens keep the abrasive inside the machine. Screw conveyor, an elevator and sand cleaner provide returning and continuing cleaning of the abrasive. Standard equipment includes PLC Siemens, display, automatic or manual mode, automatic start-up of turbines, working-hours counter, variable frequency drive of the cylinder drive, etc. Machines may be built into highly productive lines for basic color application, including drying chamber, automatic coloring chamber and drying tunnel.

Finally, i will introduce the continuous overhead monorail shot blasting Machine. The flexibility of overhead monorail transport offers a variety of possibilities for optimum material flow and contributes to a considerable reduction of finishing costs. Monorail systems solve for blast cleaning and handling problems, fitting seamlessly into a production line. The transport hanger is loaded with components outside the machine and then moves into the shot blast cabin where all surfaces of the workpieces are treated in one passage.

Part 2: Auto Shot Blasting Machine Application 

Shot blasting machine is a processing technology which steel shots impacted on the surface of material objects at high speed through blast turbines. Compared with other surface treatment technologies, it is faster, more effective, and can be partially retained or the casting process after stamping.
