Talking about the characteristics of rotary automatic sandblasting machine

Turntable automatic sandblasting machineIt is a kind of sandblasting equipment that is currently used more. Its working principle is the same as that of other automatic sandblasting machines. It uses compressed air to spray abrasives out at a high speed, thereby blasting the surface of the workpiece. With the development of the industry, there are more and more requirements for the surface treatment of the workpiece before coating, and the requirements are getting higher and higher. The application range of the rotary automatic sandblasting machine is also expanding, but many people are still not very familiar with its characteristics. Understand, let's take a look at what features it has?

The number of nozzles of the rotary automatic sandblasting machine is large, and the sandblasting volume is large. Generally speaking, there are about 6-10 nozzles. This is different from the small sandblasting room used in the past in which fully enclosed workers directly reach into the room to operate. However, due to the large number of nozzles, when using a rotary automatic sandblasting machine, a large positive pressure and a large amount of quartz sand dust will be generated in the machine, and a lot of noise will also be emitted.

The blasting volume of the rotary automatic blasting machine is small. The diameter of the turntable is generally 1500～2500mm. The nozzle is fixed on the top of the turntable, and the turntable rotates continuously, and the workpiece to be sprayed continuously passes through the sandblasting section on the turntable. There is a fixed and closed cover above the turntable. The cover space, that is, the sandblasting space, cannot be too large due to the restriction of the turntable and the operating port. Therefore, there is no buffer space for the airflow of the sandblasting. There are problems with dust running through the gaps of the hood and large amount of sand in the ventilation system, and it is also difficult to organize the airflow in the blasting chamber.

Small quantity and large quantity, continuous operation. The turntable automatic sandblasting machine uses compressed air to spray stone yellow sand to remove oxide scale, rust and dirt on the surface of the workpiece. The turntable rotates continuously. When the sprayed workpiece on the turntable turns to the operating position, people must constantly turn the sprayed For the workpiece, the sprayed workpiece is taken out at any time, and the workpiece to be sprayed is placed on the plate at any time, so that it runs continuously. The workpieces sprayed by the rotary automatic sandblasting machine are small, but the quantity is large. This requires the operator to approach the sandblasting machine and operate continuously, that is, there should be strict requirements on the air dust content of the operating position.
