What is the shot blasting machine

Shot blasting machine is a casting equipment that uses high-speed shots thrown by a shot blaster to clean or strengthen the surface of a casting. The shot blasting machine can perform sand dropping, core removal and cleaning on the casting at the same time. Some areas are also known as blasting machines and blasting machines.

Shot blasting machine is mainly composed of shot blasting machine, shot blasting room, purge room, pellet circulation system, dust removal system, guide roller, support roller, protection roller, sealing curtain and sealing roller.

The key of shot blasting machine is composed of 4 components:

① The shot blasting machine generally uses high-speed centrifugal impellers to projectiles in a certain direction under the effect of high centripetal force. In the process of work, some shot blasters can make a certain angle of shaking or move up and down.

② Projectile collection, separation and transportation equipment.

③ Make the castings continuously and continuously rotate during the whole process of shot blasting and rust removal.

④ Dust removal equipment. Sand blasting room: no deep bottom pit (or no bottom pit), low capital construction cost, short construction cycle time

Main points of shot blasting machine maintenance

(1) Orientation port angle adjustment of the directional sleeve: After feeding, the prepared casting is shot blasted. According to the condition of the casting surface, slightly adjust the direction of the directional sleeve of the shot blaster so that all sides of the casting can be processed. . After determining the best direction through trial production, mark it with a marker.

(2) Adjustment of the pellet separator: first check whether the adjustable shutter can be moved flexibly, and then adjust the load so that the pellets continuously flow into the separator. Check whether the pellets fall like a curtain when the material is discharged. If not, Then repeatedly adjust the shutter until the pellets fall like a curtain.

(3) The wear-resistant linings and blades of the blasting chamber inner wall are extremely prone to wear and tear, and should be regularly inspected and replaced.

(4) The abrasion wheel should be replaced in time if it is more than 15 mm. If it is used continuously, the radial scattering angle of the projectile will increase, which will accelerate the wear of the guard plate and reduce the cleaning effect.

(5)There are deep grooves inside the directional sleeve or the directional sleeve’s directional mouth is ground away about 10 mm and should be replaced.
