A stamp mill was a mechanical crusher, noisy, heavy and somewhat awkward to operate. The stamps were heavy metal weights that were lifted and dropped on the ore by a crankshaft. The crushed ore would then be further refined, usually by a mercury or cyanide process.
The stamp battery crushes in two ways, by compression as the result of the impact of the stamp falling upon the ore over the die, and by the abrasion or attrition of the particles of rock upon each other when moving from the impact of the stamp. Crushing by impact is especially the case with coarse ore, but it is not necessary that each piece and particle of rock be caught between the metal surfaces of the shoe and die, nor is the crushing by impact confined to the coarse rock. The strains of compression from the impact are communicated to all the coarse ore in the bed between the shoe and die.
A consideration of these principles will show wherein stamp-mill crushing is radically different from all other forms of rock-reduction, will point out. why the limit of economy can be passed in fine breaking in the rock-breaker, and will indicate why a fine or a soft talcose ore often requires the addition of coarse or hard ore to act as the ‘grinders’ before it can be satisfactorily crushed or comminuted.Our gold stamp grinding mill have exported to America, Italy, Turkey , Australia , Singpore, Indonesia, Vietnam , Iran, India, Chile, Venezuela, Libya, Angola, Kenya, South Africa, Pakistan , Yeman, Eygpt, Nigeria, Tajikistan , Saudi Arabia , Zimbabwe, Dubai, Vietnam, Philippines, Brazil and so on.
