Autogenous Mill. Autogenous mill is a type of grinding equipment that crushes material by mutual impact, grinding and peeling effect among material grains. In 1880, cylindrical grinding mill was invented. In 1899, it was used at a gold mine. Since then, it was discovered that autogenous grinding of ore is possible.Web

2–5 micron range. Dry grind mills can be used in conjunction with air classifiers or screeners to form a closed grinding process loop (Figure 5). By continuously classifying out fines and return-ing oversize material to the mill, such systems can very efficiently provide sharp particle-size-distribution grinds. As a rule of thumb, dry ...Web

Grind curves give the steady-state values of the performance variables throughput, power draw, and grind in terms of the mill filling and critical mill speed.
