How does the projectile accelerate from the nozzle under the action of the high-speed rotating blade?

During the working process of the stone shot blasting machine, how the projectiles accelerate from the nozzle and the power transmission method used directly affect the working efficiency and performance of the machine. Inside the machine, a rotating blade or impeller is usually installed. . When this blade starts to rotate at high speed, it generates powerful centrifugal force. Projectiles are loaded at the nozzle, and as the blade rotates, they are ejected by centrifugal force to form a fan-shaped beam and shoot towards the stone surface to be treated at high speed. The action of this centrifugal force allows the projectile to acquire high speed and kinetic energy, allowing it to move quickly in the air and generate sufficient impact and friction to effectively clean and treat the stone surface.

As for the power transmission method, stone shot blasting machines usually use electric motors or hydraulic systems. In a motor-driven machine, the motor is connected to the rotating blade via a belt drive or directly, causing it to spin rapidly. As the main power source, the electric motor provides sufficient power to drive the rotation of the blade and generate the required centrifugal force. In contrast, hydraulic systems are powered by a hydraulic pump. A hydraulic pump sends compressed fluid into a hydraulic cylinder or hydraulic motor, which drives the blade to rotate. This hydraulic transmission system has the characteristics of high flexibility and fast response, and the output power and speed can be adjusted as needed.

No matter what power transmission method is used, its purpose is to provide sufficient power and speed to meet the working requirements of the stone shot blasting machine. The machine needs to have enough kinetic energy to generate strong centrifugal force so that the projectile can quickly accelerate and effectively treat the stone surface. Therefore, the design and performance of the power transmission system directly affect the efficiency and performance of the machine.
