A shot blasting machine is a type of processing technology that uses a shot blaster to project steel grit or steel shots at high speed onto the surface of a material. Compared to other surface treatment technologies, it is faster, more effective, and can be used for parts of the casting process that need to be retained or stamped.
With the development of shot blasting machines, they have extended and expanded into many industries, such as removing tire marks at airports, removing old markings on municipal roads, roughening concrete and removing surface laitance, cleaning epoxy floors, rust removal on ship decks, waterproof shot blasting processes on bridge surfaces, and more. Mobile shot blasting machines, commonly referred to as road shot blasting machines, are used in these industries. Other extended industries include anti-corrosion rust removal shot blasting equipment for oil storage tanks, specialized shot blasting machines for stone surfaces, large steel pipe inner and outer wall shot blasting machines, etc. Since the invention of the shot blasting machine, these high-difficulty industries have been made convenient, saving manpower and simplifying the work process.
Rubber belt shot blasting machine: This type of machine is suitable for surface rust removal or shot peening of various types of medium and large batch production workpieces. The workpieces must be able to withstand collisions and must weigh less than 50kg in the rubber belt shot blasting machine. This machine can be used as a standalone unit or in a production line; it falls under the category of casting machinery.
Working Principle: The workpiece is placed in a rubber belt drum, the belt moves forward, and the workpiece continuously rolls. The shot blaster projects steel shots at high speed and uniformly onto the rolling workpiece's surface. The steel shots flow through holes in the belt into a screw conveyor, then are transported to a bucket elevator, lifted to a separator for separation, and dust is sucked into a dust collector by a fan where it is filtered. Clean air is discharged into the atmosphere, and the dust on the filter bag is mechanically vibrated into a collection box which the user can periodically clean. Waste sand flows out through a waste pipe and can be reused by the user. The shot and sand mixture is collected back into the equipment body, separated by the separator, and the clean shots are used again by the shot blaster to treat the workpieces. This machine is suitable for cleaning and strengthening small castings, forgings, stampings, gears, springs, etc., especially parts that are susceptible to collisions. It is very suitable for rust removal and pre-treatment of fasteners.
Hook Shot Blasting Machine: The hook shot blasting machine is a standard model of shot blasting cleaning machine with a working cylinder diameter of 900 to 1300mm and a height of 1300 to 2200mm. Standard models have 2-7 blasting heads and a maximum load capacity of up to 10,000 kg. This type of shot blasting machine has high production efficiency, a wide range of flexibility, ideal for cleaning and strengthening equipment, and is simple to operate. Simply load the workpiece onto the machine, press start, and within a short time (usually 5-7 minutes), the entire cleaning process is completed, removing all dust and residual shots. It is mainly suitable for the surface treatment of various medium to large castings, forgings, weldments, heat-treated parts, including fragile and irregularly shaped workpieces.
Working Principle:
When the machine is operational, once the preparatory work (dust removal system, elevator, screw conveyor, etc.) is completed, the machine starts to work normally. First, the hook descends to lift the workpiece, ascends to a certain position, and then moves along the rail into the shot blasting chamber. When it reaches the predetermined position, it stops and starts rotating. At this time, the shot blasting chamber door is closed, the shot blaster is opened, and the shot supply gate is opened, beginning the shot blasting cleaning of the workpiece. This process is repeated until the work is completed, and the machine is stopped in sequence.
