Autogenous Grinding & Semi Autogenous Grinding Circuits
Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed by ball mills or ...

Grinding Mills and Their Types – IspatGuru
Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding. Milling, sometimes also known as fine grinding, pulverizing or comminution, is the process of reducing materials to a powder of fine or very fine size.

DESIGN AND ANALYSIS OF BALL MILL INLET CHUTE FOR …
In ball mill, ball has to be charged around 30-32% in first and second compartments. Balls are in the range of 50-90mm in coarse and 15-50mm in fine grinding. Grinding of material takes place by means of collision or attrition or tumbling action takes place between the balls and the charge.
Grinding Mill Design & Ball Mill Manufacturer
Grinding in a ball mill is not selective as it is in a rod mill and as a result more extreme fines and tramp oversize are produced. Small Ball mills generally operate at slightly higher speeds than rod mills and thereby impart a cascading action to the grinding media.
