Marmomacchine Pellegrini is a Division of Pellegrini Meccanica S.P.A. headquartered in Verona, Italy and is the leading manufacturer of processing machinery for rough-surfacing marble, granite, natural and artificial stone products and concrete items, such as:

  • Special rough-processing equipment (ruling, chiseling, scratching, roto-brush-hammering)

  • Kerb rough-finishing machinery

  • Washing, drying, and brushing plants for slabs or strips

  • Sound reduction boxes

  • Automatic and semi-automatic handling systems for gang-sawn slabs and for strips

  • Safety systems and devices to protect the working area around automatic machines

So why consider an alternative surface to polished material? Polished stone is very nice to look at, BUT the stone must be very good, and polishing is expensive. So MarmoMacchine Pellegrini developed a series of machines for an alternative: ROUGH FINISHING. The equipment recreates at low cost the traditional rough finishes used for outdoor flooring and similar applications where a polish is inappropriate.

The areas where these finished are used include:
  • Outdoor paving
     
  • Vertical wall facings where a variety of finishes is needed to offer differing feel and texture
     
  • Urban stones such as bollards, kerbs, parapets
     
  • Recovery of stones that cannot be used for polishing.
Rough finishing can be created with a number of different processes:

  • Bush-hammering. This reflects the traditional hammer treatment of stone, dating from Roman times if not before. Used for almost all stones.
     

  • Flaming. Used with high quartz granites, and with some types of sedimentary stones. Can be a very fast and economic operation.
     

  • Sand-blasting. Used with all stones when a very fine grade finish is needed. Can be used with masks to create patterns. The similar Shot-blasting technology uses hard steel grit in dedicated machines and offers very fast production.
     

  • High pressure water. The MMP system is called Waterstorm-Master. Here the roughening effect is obtained by the use of mechanical energy carried by a high pressure water jet. This system can process almost all stones, and give a wide range of finishes. Can be used with thin stones, and there is no damage to the internal stone structure.
