The drum-type shot blasting machine appeared earlier and was widely used in many fields of casting at the initial stage. With the development of the shot blasting machine, the crawler-type shot blasting machine appeared and gradually replaced the drum-type shot blasting machine in the market. The structure of the crawler-type shot blasting machine is relatively simple. According to the positive rotation of the crawler, the falling cleaning and cutting of the casting parts can be built. The rotation of the crawler can send the cleaned casting parts out of the shot blasting machine. The drum-type shot blasting machine has less functions, The drum-type consumable cost is relatively high, and the production cost is also high, and the drum-type shot blasting machine can not clean more than the crawler-type shot blasting machine at one time. However, many similar castings still need to be cleaned by roller shot blasting machine. That is, the cost performance ratio between the two is high, and the crawler type shot blasting machine is higher than the roller type. Today's drum type shot blasting machine has inclined drum type full-automatic loading and unloading shot blasting machine: it can also complete full-automatic loading and unloading, with a cleaning capacity of 1.2 tons.
