    The separation effect of the shot, sand and ash separator in the shot recovery system directly affects the life of the wear parts and the chamber body guard of the shot blasting machine. The commonly used separator adopts wind separation to separate the projectiles, sand and dust in the recovered shot. It is easy to cause incomplete separation during the use process. The recycled projectiles contain impurities such as dust and sand, and the projectiles entering the shot blasting machine contain impurities. The more impurities, the more serious the wear on the wearing parts of the shot blasting machine, such as the guard plate, the blade, the shot separation wheel, and the directional sleeve, which reduces the service life of the wearing parts and increases the production cost. The magnetic air separator separates the sand, dust and projectiles in the pellets by means of magnetic separation + air separation, which improves the separation effect.

    Structural features of the magnetic wind separator: see figure

    The sand, dust and projectile mixture after shot blasting are transported to the screw of the magnetic air separator through the bucket elevator. The screw rotation pushes the shot mixture to the trommel screen, and the large particles of impurities are screened by the trommel screen and sent to the waste box and passed The waste pipe is sent out. The dust and projectiles are uniformly clothed by the outer spiral of the trommel screen to form a curtain. The primary air selection sucks the dust away. The primary magnetic roller rotates to separate most of the projectiles and enters the silo after the secondary air selection. After the magnetic separation, it is returned to the chamber through the flow pipe and reused for the second time.
