How to choose the size of steel shot

　　First, let's take a look at the effect of the size of steel shot on the effect of sandblasting and rust removal. The larger the diameter of the steel shot, the faster its rebound speed and the greater the force of hitting the surface of the workpiece. Therefore, for some thicker workpieces, using steel shots with larger diameters can better clean the impurities and rust on the surface. However, for some thinner workpieces, using steel shots with larger diameters may cause pits on the surface of the workpiece, affecting the aesthetics.

　　Secondly, let's take a look at the effect of the size of steel shots on the efficiency of the sandblasting production line. Generally speaking, the larger the diameter of the steel shot, the higher the output of its production line. However, this also needs to be determined according to the specific production line conditions and the size of the workpiece. If the diameter of the steel shot is too large, it will cause the running speed of the production line to decrease, affecting production efficiency.

　　Finally, let's take a look at the effect of the size of steel shots on the labor intensity of workers. Generally speaking, using steel shots with larger diameters can better clean the impurities and rust on the surface, but it also requires higher technical skills from workers. If the workers' skills are not up to standard, pits may appear on the surface, affecting the aesthetics, and also increasing the labor intensity of workers. Therefore, when purchasing steel shot, we need to determine the diameter of the steel shot based on the specific workpiece size, surface quality requirements, production line output and other factors. Only by choosing the right steel shot size can we achieve the best sandblasting and rust removal effect, improve production efficiency and reduce the labor intensity of workers.
