1. Mechanical characteristics: 1) Stirring cage recovery system: High-pressure air jets attack the workpiece surface, causing sand grains to fall into storage by gravity. The sand tank and stirring cage sand and dust conveyance system gather and transport them to the sand and dust separation system for recycling, increasing the use rate of contrast sand particles. 2) Sand and dust separation system: Dust is generated during the grinding process when various abrasives come into touch with one another. The separation system's primary duty is to successfully separate and discharge dust from the recovered sand-dust mixture, while also recycling usable sand grains. This cycle repeats until the entire useful product has been consumed. 3) An independent lifting control and adjustment system comprises a rotating angles according to the thickness of the workpiece, ensuring an optimal fit between the spray gun and machined parts within a range of 650mm for optimal sandblasti…
