Removal of cement and exposure of aggregates from the surface of paving stones, slabs, curbstones and block steps.
- Sustainability and fast amortization due to modular expansion stages
- Easy integration into existing systems due to flexible design and control
- Durable machine due to stable and high-quality construction
- Long service life and cost saving by using hardened tool steel for the wear parts of the turbines
- Easy training of the operating personnel due to simple operation
- Space saving due to integrated filter system
Of pavers, slabs, curbstones, block steps – optionally face and/or side surfaces. During processing, cement is removed and the aggregates are exposed. Shotblasting machines use steel or stainless steel balls as abrasives. In operation, the steel or stainless steel balls, standard size 0.6–0.8 mm, get thrown by means of 2–4 turbines at the products to be shotblasted . Depending on infeed and outfeed situation, processing is done cyclewise or in a flow . Blasting speed and belt speed are adjustable in relation to the product to be treated and the desired surface appearance . Turbine and belt drive are frequency-controlled for a homogeneous treatment from rough to fine. The quantity of abrasive is electro-pneumatically adjustable.
The perforated belt, ribbed transversely to the running direction, ensures a proper transport of the layers without drifting of single stones and refeed of abrasive
material to the material silo. Abrasive material which stays on the shotblasted products is removed by a height-adjustable high pressure blowing device or a magnetic strip and fed back to the material silo.
Blasting chamber and turbine housing made of manganese steel. Available working widths 850 and 1,200 mm. A cartridge filter unit is installed as standard on the shotblasting machine. The machines are equipped with an independent electro-pneumatic control and operation panel. Available as stand-alone machine, integrated in value adding lines or as a bypass
of the stone making machine. Shotblasting can be combined with all surface value adding processes.

Concrete block refinement
creates room for creativity
The demand for diverse shapes and sophisticated surface designs, such as natural-looking stone surfaces, is constantly increasing.
Stone calibrating machine
For laboratories. Test products are calibrated before breaking and flexural strength tests are carried out.
Special and laboratory machines – Multicut saw
For production of baseboards, sample products, strips, cubes made of concrete and terrazzo slabs.
The control technology from SR SCHINDLER enables you to increase the efficiency of your systems.
In order to be able to design the production and value adding process of concrete products efficiently and economically efficient transport and handling systems are required.
Complementary to the production and finishing lines, SR-Schindler also provides handling technology and packing lines for paving stones and slabs.
From paving stones (for impregnation or coating layer by layer) and slabs (for impregnation or coating row by row) for optimum protection.
