Tumble blast machine, formerly known as chain-plate shot blasting machine, is suitable for cleaning small and medium-sized castings which are not afraid of collision, because its structure is mainly a metal chain plate which can run forward and backward. It cooperates with the left and right discs to form a concave space which can accommodate castings. The shot blaster sprays steel balls from the top of the space to realize the cleaning and strengthening of parts. The steel balls and cleaning materials flow down from the gap between the chain plates and the holes in the chain plates to realize the recycling.
Due to the use of steel chain plate, the continuous collision between steel castings and steel chain plate occurs during operation, resulting in relatively high noise, which easily causes fatigue of operators and disturbs the surrounding environment. At the same time, some shot blasting machine parts with softer materials are also vulnerable to be damaged by steel chain plate. As a result, first in Qingdao, China, the production area of special tape, rubber shot blasting machine crack came into being.
Compared with the chain plate caterpillar, the caterpillar of rubber shot blasting machine has the characteristics of low cost, simple assembly process and rapid replacement, but the more important advantage is that rubber has high elasticity. It has almost no noise in the use process. After all kinds of soft metal parts rolling on rubber track, it will not be knocked and damaged, and the quality is guaranteed. So in recent years, there is a trend that rubber track will replace metal track.
Because there are many factories producing shot blasting machines, the size of each one will be different, so we need to pay special attention to the selection of models. We must read the machine instructions, select the type according to the instructions, and consult the shot blasting equipment manufacturers when necessary, because the professional crawler manufacturer generally has technical specifications and inventory of various types of shot blasting machine track.
