The workpiece surface will contains oxidations, rust, welding flags, dust or other dirty when in production, machining, transportation or storing. To extend the workpiece life, the surface should be cleaned and coated protection.
The H beam shot blasting machine is a dry cleaning equipment. The high speed shots impact the surface to clean the dirty. It is suitable for H beam, BOX beam, welding structures, steel plate, profile beam and other different shapes.
After shot blasting, the surface dirty can be removed, and the welding stress can be released also. So it can reduce the deformation and improve the fatigue resistance, enhance the paint adhesion.
HP shot blasting machine has following features:
The clean room and blasters are placed reasonably and the blasting range is wide.
The acentric direct joint shot blasters with big volume and high blasting speed can give high efficiency, surface grade to be Sa2~Sa2.5.
The separator is curtain type. The shots are blowed to a curtain, use wind to separate the dust, oxidations, broken shots from the useful shots.
The dust collector is pulse filter type. The wind speed is 0.4-0.8m/min. Cloth bag wind is 2-4m/min. So same wind volume, the filter size is much smaller than cloth bag. And the filter tank is easy for installation, transportation, and commissioning. Dust exhaust is less than stardard 100mn/m3 .
