A new grinding process: HOROMILL®
The mill operation stability is spectacular: the circuit rises to its nominal regime in 5-10 minutes and the circulating load keeps constant to within 2 t/h! This is due to the low material quantity in the circuit; the response time is 50 seconds. Of course this stability leads to a very high regularity of the finished product.
