Calibrating

Compensation of unevenesses of the surface which are beyond the allowed tolerances. Calibration is a prerequisite for the grinding process. The machine can also be used for the layer-by-layer milling of single or double side masonry and chmney blocks, allowing for a motarless processing.

Calibrating

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 devices
  • Time saving and improved user comfort thanks to electric height adjustment
  • Cost and space saving in dry treatment due to elimination of grinding water (no water treatment required) and special waste disposal
  • Further cost cuttings possible due to the usage of dust which occurs during the calibration process as a filler in the concrete mixture

Application / Features

  • The grinding machine serves to mill-off unevenesses of the surface of slabs and pavers which exceed the allowed production tolerances, i.e. variations of the height as well as of conicities
  • Moreover, the machine can be used for the unilateral and bi-lateral layerwise milling of both wall stones and chimney stones in order to allow a mortar-free processing
  • The treatment can be executed in dry mode or in wet mode
  • Depending on the customer´s demand the machine can be equipped with up to 3 working stations
  • Two working widths can be offered: 850 mm and 1,200 mm
  • The machine is equipped with with lateral guidances which are optionally adjustable by means of an electric motor
  • Heavy-duty tunnel design
  • Armoured machine bed, made from grey cast iron with hardened high-precision manganese steel ground plates
  • Multi-layer armoured conveyor belt, make „Siegling“ for the planar transport of the products through the calibrating stations
  • The calibrating stations are equipped with high-performance milling diamonds, attached to universal mounting devices
  • Quick and easy tool exchange due to dovetail guidances
  • VFD-driven main drives and vertical movement of each calibrating station
  • Independant control and operation panel and visualization
  • Processing parameters are being saved for each indivual product type
