Shot blasting method The shot blasting method uses shot blasting equipment to remove the markings. Its working principle is: the motor drives the impeller body to rotate, relying on the centrifugal force, the shot blasting machine throws the shot material (steel shot or sand) onto the working surface at a high speed and a certain angle, so that the shot material impacts the working surface. Then the inside of the machine is cleaned by the airflow of a matching vacuum cleaner to separate the pellets and the cleaned impurities and dust, and the recovered pellets are repeatedly cyclically projected to achieve the purpose of cleaning the road markings.

1. During the operation of the shot blasting machine, by controlling and selecting the particle size and shape of the shot, and adjusting and setting the walking speed of the machine, the shot flow rate is controlled to obtain different shot strengths and different surface treatment effects. Shot blasting machines can be divided into hand-push type, vehicle-mounted type and white line type according to the walking mode.

2. Shot blasting method is mainly used for cleaning the marking of cement concrete pavement, especially suitable for the cleaning of normal temperature marking. Sandblasting methodSandblasting is a method of cleaning the surface with abrasives (shot blasting glass beads, steel shot, steel grit, quartz sand, emery sand, iron sand, sea sand) advanced at high speed through a nozzle. Sandblasting media can achieve different cleaning effects. Sandblasting cleaning has applications in machinery manufacturing, industrial production, road maintenance and other fields.

3. The sandblasting type road marking removal machine can achieve different cleaning effects by controlling the type and particle size of sandblasting, and it is more effective for the removal of normal temperature markings and markings in rough road grooves. Since a large amount of dust is easily generated during sandblasting, a vacuum cleaner should be connected during work to achieve dust-free construction.

4. Or by adding liquid medium to the abrasive, dust pollution during sandblasting can also be reduced. In order to achieve a better cleaning effect, the sandblasting road marking remover has a slower walking speed and low work efficiency, so it is often used for road marking removal in sections with low workload and low traffic volume.
