Principle of sandblasting machine

Sandblasting is the use of high pressure abrasive to the surface of the object, to achieve the desired effect or to polish the surface or to obtain the desired roughness, to lay the foundation for the subsequent coating.

Sand blasting machine is the most widely used tool in abrasive jet technology, and its classification can be divided into different results according to different standards. First of all, according to the way the abrasive enters the spray gun, it can be divided into inhalation type and pressure type. The quine is based on the compressed air as the power, through the high-speed movement of the air to form negative pressure, the abrasive such as pomegranate sand through the sand pipe suction into the spray gun, and by the nozzle at high speed, but hand and with high speed, a sharp corner, hardness of abrasive such as pomegranate sand on the workpiece surface treatment. In this form the compressed air produces both the suction of abrasive into the airbrush and the power of abrasive out of the airbrush at high speed. The latter is through the compressed air in the abrasive tank should be built in the working pressure will be abrasive through the sand pipe into the spray gun and then through the nozzle high-speed contact with the workpiece surface.

On the basis of the two products in accordance with the grinding of the suction machine for a type and wet type two categories.

Under the same conditions, the working pressure of the suction sandblasting machine is lower and the consumption of compressed air is also less. When the abrasive such as pomegranate sand is sandblasted, it is called dry sandblasting machine. The working state of abrasive is wet water, called wet sandblasting machine. Compared with the dry sandblasting machine, the biggest characteristic of the wet sandblasting machine is that the dust pollution in the sandblasting process is well controlled and the working environment of the sandblasting operation is improved.

In addition, it can be divided into manual and automatic sandblasting according to the worker's work during the sandblasting process. But whether it is the above kind of sand blasting machine, the use of pomegranate sand blasting, do not need to replace the existing device.
