Blasting technology is used in almost all industries of metal. Shot blasting and sand blasting are both a kind of surface cold treatment cleaning technology. It is a necessary process to use steel grit or steel shot to remove surface stains and rust and verify the integrity of the product surface. Compared with other surface treatment technologies, its surface treatment ability and environmental friendliness are faster and more effective, which is the first choice;
Shot blasting uses the centrifugal rotating turbine blades of the blasting head to throw high-speed (about 70-90 m/s) steel medium (high-speed beads of steel, copper, aluminum or other materials as the shot blasting medium), and project it onto the upper surface of the shot blasting machine. Deburring, sanding, cleaning or strengthening the surface of castings at a certain angle, or removing rust, paint or other coatings, etc.;
Sand blasting medium is pneumatically accelerated by compressed air instead of a centrifugal turbine. Sand or other abrasives are driven by compressed air through a tube, allowing the user to control the spray direction, and finally sprayed onto the part through a nozzle
Different blasting materials:
Shot blasting: because of the large centrifugal force of shot wheel, metal shot abrasive is used in most cases, and the separator is used for recycling;
Sand blasting uses compressed air, either metal shots or sand such as Glass beads, but Glass beads are not recyclable and disposable.
The effect on the environment:
Shot blasting has a dust collector, it greatly reduces the impact on the environment and basically achieves a dust-free treatment;
Large sand blasting equipment is equipped with a dust collector, and small sand blasting equipment works in the open air, which has a certain impact on the environment;
Differences in processing workpieces:
Shot blasting is basically the cleaning of metal surfaces, and can also be used for stones, concrete, etc.;
Sand blasting can be used for metal, plastic, glass and other fragile products;
We have decades of experience in choosing the right shot blasting or sandblasting. Welcome to inquire.
