Qinggong Machinery has rich experience of producing all kinds of shot blasting machines for pavement, stone, concrete block, brick, marble, granite, etc. We are also one of the earliest factories that start to produce stone shot blasting machine in China. We have sold this type of machine to Australia, USA, UAE, South Korea, etc, and have won high satisfaction from customers.
We usually choose roller type or rubber belt shot blasting machine to transport the stones through the blasting system. Roller conveyor type has minimum length limit to stones but can clean the bottom surface. The transporting speed is adjustable by converter according to quantity and size of customer's work-pieces.
Multiple blast wheels are installed around the working chamber according to customers' requests to the surfaces of stones they need to clean.
For pavement stones, customers usually only request to clean 1-2 surfaces, so we usually use 2-3 blast wheels installed on top of the housing.
A bush-hammered surface will appear on the surface of stones, for an artistic appearance or increasing roughness for preventing slip.
To clean the dust produced during the blasting process, we adopt bag type dust collecting filter. The dust collecting efficiency is up to 99.5%.
