Application field

The universal impact mills type “P IMPACT MILLS TYPE “P – D – PC” are specially used for:

  • Production of fine powders and sands of limestone and dolomite for glass industries, mortars, plasters, agglomerated floors with resin or cement (0÷3 mm/0÷8 mm)
  • Grinding of clays for production of roof tiles, bricks and extruded floor tiles
  • Particularly suitable for grinding and contemporary drying of products with moisture 4÷8% (depending on raw material)
  • Capacity range: 1÷12 ton/hour
  • Limestone, marble, calcium carbonate, dolomite
    fine powder and sand for production of: premixed dry mortars, terrazzo tiles, animal feed, glass industry
  • Gypsum
    pre-grinding before calcining
  • Plaster
    refining for production of: plaster of Paris, plaster for ceramic moulds, special plasters
  • Clay
    dry grinding for: bricks, roof tiles, dressed floor tiles, abrasives, refractories, ceramic products for recycling in new production
  • Waste of bricks
    red earth for tennis court, chamotte for ceramic bodies
  • Kaolin
    pellets of washed kaolin
  • Waste of industrial products, such as:
    calcium oxide, hydrated lime, chemical products, horn and nails, petroleum coke, coal, metal alloys
  • Body of cast iron with hinged front cover for maintenance; the grinding chamber is fully protected with replaceable plates.
  • Toothed grinding plates and hammers of manganese steel; on request hammers protected with wear resistant alloy welded on.
  • Bar grate with adjustable opening or with perforated plate, easily replaceable.
  • Shaft of Cr.Ni.Steel on ball and roll bearings, grease lubricated and protected with labyrinth.
  • The mill can be easily transformed from model P to the corresponding model D, by replacing some parts.
