Stamp mill, a specialized machine for reducing ore to powder for further processing or for fracturing other materials A place of business for making articles of manufacture. The term mill was once in common use for a factory because many factories in the early stages of the Industrial Revolution were powered by a watermill, but nowadays it is only used in a few specific contexts; e.g., A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.On modern mills, the cam is arranged to lift the

Milling can be done with a wide range of machine tools.The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers: milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures.

The result by the 1860s was a regional hybrid, the California improved stamp mill. The standard unit consisted of a mechanical jaw crusher for breaking rock, an automatic feeder, a five-stamp battery with fine-tooled, interchangeable parts, a heavy iron mortar, and an apron over which the pulp flowed on its way through the milling circuit.

This was with the viewpoint that the tube-mill finds its greatest efficiency in reducing 30 or 40-mesh material to 200-mesh, the Chilean mill in medium grinding, and the stamp in coarse crushing. With this idea it has been proposed to use heavy stamps crushing through a 4 to 12-mesh screen, delivering to Chilean mills grinding through a 30 or 40-mesh screen to tube-mills sliming to the desired

Alaska Gastineau Mill By 1911 Bart Thane had acquired control of the Perseverance Mine, which had a 100-stamp mill, in Silver Bow Basin. The mine ran seasonally since the snow was too deep in the winter to continue to operate and the hydro power running the mill was not available in the winter.

A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material It uses heavy steel stamps to crush and break apart material releasing the valuable gold from worthless rock allowing for the extraction of gold for further refiningAs a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and
