Crawler-Type Shot Blasting Machine is suitable for cleaning small and medium-sized castings that are not prone to damage from impact. Its structure primarily consists of a reversible metal chain plate, paired with a disc on each side, forming a concave space to accommodate the castings. The shot blaster ejects steel shots from above the space, enabling the cleaning and strengthening of the parts. The steel shots and debris flow through the gaps between the chain plates and the holes in the plates, allowing for recycling.

However, since this machine uses a steel chain plate, the continuous collision between the steel castings and the steel chain plate during operation generates significant noise, which can cause operator fatigue and disturb the surrounding environment. Additionally, softer materials such as copper and aluminum parts are prone to damage from the steel chain plate. As a result, the rubber shot blasting machine crawler was developed, initially in the special rubber belt production area of Qingdao, China. Compared to the steel chain plate crawler, the rubber shot blasting machine crawler offers advantages such as lower production costs, simpler assembly processes, and quicker replacement. More importantly, rubber's high elasticity results in almost no noise during operation, and soft metal parts rolling on the rubber crawler are not subject to impact damage, ensuring product quality.
