Hammer mills are characterised by their considerable grain size reduction ratio.
They are suitable for handling clay of any kind, ceramic mixtures with a high content of aggregates and raw materials with a low to medium hardness.
These mills are composed of a thick sheet metal casing, housing on the inside a set of circular and lateral armours coated with wearproof material; a rotor carrying the grinding hammers that are made of a special long-life alloy; a lump crushing hammer unit and special steel sizing grids.

This Hammer Mill is available in different versions (P.I.G./A, P.I.G./B, MAXI/P.I.G.) and configurations (P.I.G./Dryer - World Patented) to adapt to different requirements.
The Hammer mill is ideal for the rough milling of raw material at the beginning of the raw material preparation process, but also suitable as finishing mill thanks to its low level of wear and above all its low consumption with respect to traditional mills, edge-runner mills and roller mills.


Both in the field of pressed and extruded ceramic products, P.I.G. Hammer Mills are appreciated for giving the ground product the right degree of refining.
Furthermore the resulting shape of the ground product guarantees a better resistance of the finished green piece.

P.I.G. DRYER
P.I.G. Hammer mills can be used for the closed-cycle pre-crushing and milling of raw materials with humidity content of up to 12-14%.
This possibility is granted by the application of a heating system on board the mill with automatic control of the electrical and heat parameters, in order to optimize consumption and improve performance.

In some cases, the PIG Dryer type, thanks to their special system, eliminate the need to purchase a specific drying system.
