What are the effects on cleaning workpieces by the blasting capacity of a shot blasting machine?

The blasting capacity of the rotary table shot blasting machine is a very important factor for the job cleaning effect. If the blasting capacity is too high, it not only affects the cleaning efficiency of the shot blasting machine, but also will affect the properties of castings, giving rise to high surface hardness and reduced processing performance. If the blasting capacity is not enough, the casting surface quality will not meet the design requirement. The applicable blasting capacity: the ratio between the abrasives on the castings and the weight of the casting should be 10-20. Different ratios should be selected as per the complexity of the castings. The ratio for the complex casting is high and sometimes can reach 20-25. The blasting capacity per unit time is also very important. 13kg of abrasives can be ejected per minute if the effective current of the blast wheel motor is one ampere. Generally speaking, if the blasting capacity is higher within a unit time, the time that is spent is less. But we can not say that higher blasting capacity is better within a unit time, because when the blasting capacity is higher within a unit time, the abrasives in the casting inner cavity may not be emptied timely. If the case occurs, the efficiency of the shot blasting machine will be reduced.
