Paver Blocks Shot Blasting Machine are predominantly used to blast concrete stones, plates and kerbstones to create an improved aesthetic appearance, taking out cement and making styling attributes such as granite chips visible. Qingdao Qinggong Machinery’s experience in this market is second to none, and there are currently more than 500 machines operating globally.

Qingdao Qinggong Machinery Paver Blocks Shot Blasting Machineperform efficient and high quality blasting of concrete/stone products like blocks, marble slabs and kerbstones.

The advantage: the blast process creates a unique character of the blocks/stone, with a high quality surface appearance, which in turn creates added value to the product.

The flexible design and control of the machine provides the optimum blasting process for various concrete/stone products. This is most important as concrete and stone are delicate material: to ensure the desired finish/appearance is achieved, the blast pattern must be uniform, and the patterns from different wheels should not overlap.

The optional use of two, three or four blast wheels in special positioning and with programmed start/stop functionality, allows the targeted treatment of both the horizontal and vertical visible surfaces – e.g. on fence blocks, marble stone,kerbstones or block steps.

The Paver Blocks Shot Blasting Machinecan be integrated into a production line due to its modern control system with the relevant interfaces, different belt lengths and well coordinated transfer stations (e.g. sheets or rollers). The machines can be operated easily using a Siemens Touch panel.

Qingdao Qinggong Machinery Paver Blocks Shot Blasting Machinecan be sized to treat workpiece widths from 600 to 2000 mm. Both indexing and continuous operations are possible. The belt conveyor/roller conveyor runs smoothly, at speeds from 2.5m/min to 14m/min.

The advantages:

The adjustable blast wheels provide a very uniform surface result, even at high speeds.

This is assured by smooth/stepless speed control, electro-pneumatic dosage regulation and optimal blast wheel positioning.

Furthermore, the use of hardened tool steel for the blast wheel wear parts assures a long service life.

Whilst lowering your cost per part, high values can be added to your concrete/stone products due to the consistent, uniform quality finish achieved at high process speed.

Blow-off station

Stainless steel shot is the preferred abrasive for concrete/stone applications. After blasting, a blow-off station with a high pressure blower removes the shot from the surface of the concrete blocks/stone. The nozzles are adjustable in height and therefore adaptable for the treatment of different concrete block/stone sizes.
