Shot blasting cleaning is a casting surface cleaning method that uses the centrifugal force generated by the rotation of the impeller in the shot blasting machine to throw iron or steel pellets to the casting at high speed to remove the sand and oxide on the surface.
There are many kinds of shot blasting equipment, which can be roughly divided into: drum shot blasting machine, drum continuous shot blasting machine, rotary table shot blasting machine, crawler shot blasting machine, as well as cumulative, stepping, through, catenary shot blasting machine and vacuum shot blasting machine. In addition, there are multi-functional combination shot blasting machine for cleaning complex castings, squirrel cage shot blasting machine, as well as rotary table shot blasting room, hook catenary shot blasting room, combined shot blasting room, etc. 2. Several commonly used typical shot blasting cleaning equipment
(1) Drum shot blasting machine The drum shot blasting machine uses a rotating round sheet as a carrying device for castings, which is horizontal and inclined, and can be divided into continuous operation and intermittent operation.
(2) Crawler shot blasting machine Crawler shot blasting machine is composed of a pair of circular end disc and a track, working, track rotation, drive the casting constantly turn, accept the shot blasting machine above.
(3) Hook (chain) Rotary disk shot blasting machine This machine with a number of hook (chain) and rotary plate composed of hanging mechanism for casting vehicles.
(4) Squirrel-cage shot blasting machine The equipment is composed of a squirrel-cage, a charging and discharging mechanism, a squirrel-cage rotation and a conveying cycle mechanism, and other parts of a continuously running casting carrier.
