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
- Typical applications
- Manufacturing features
- Type P, with N°4 fixed hammers
- Type D, with N°3 swinging hammers
- Download
- Limestone, marble, calcium carbonate, dolomite

- 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.
