Grinding

Customer benefits

  • High-quality, reproducible products due to planar and smooth belt transport
  • Durable machine due to stable and high-quality construction
  • High flexibility due to modular design (stations can be retrofitted) and universal holding disc for process engineering
  • Time saving and improved user comfort thanks to electric height adjustment and fully automated contact pressure control
  • Cost and space saving in dry treatment due to elimination of grinding water recycling (no water treatment) and special waste disposal
  • Further cost cuttings possible due to the usage of dust which occurs during the grinding process as a filler in the concrete mixture.

Grinding of pavers and slabs. Calibrating is a precondition for optimum grinding results. After calibration, products are ground in the grinding machine with up to 10 high-power stations. Depending on the number of grinding stations used, a surface appearance from rough to fine can be achieved. Treatment in dry and wet mode possible. In wet treatment with 10 stations, a grinding degree of maximum 220 can be reached. Dry treatment is recommendable only for facemix with a hard stone ratio of max. 50%. Working widths 850 and 1,200 mm.


Solid tunnel type segment construction made of steel. Armoured bed made of  rey cast iron with high-precision ground manganese hardened steel plates and multilayer armoured Siegling conveyor belt for planar and smooth transport of the products through the stations. Every individual station can be equipped with milling diamonds, smoothening or grinding segments. Milling diamonds, smoothening or grinding segments installed on universal holding discs. Quick tool exchange via dovetail guidances.


Frequency-controlled main drives and vertical movement of every station. Every station with contact pressure control. The machines are equipped with an independent control and operation panel with visualization. Processing parameters per product type can be saved. Can be combined with other value adding steps
like chamfering, shotblasting, curling, coating and impregnation.
