Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between mm and mm in diameter.
· The high energy ball milling (HEBM) was undertaken at a maximum centrifugal acceleration of the milling balls of about 600 m/s 2. The HEBM processing time was varied in the range 1–120 min. The obtained composite Cu/Cr powders were then consolidated in a vacuum in a spark plasma sintering (SPS) system (Labox 650, Sinter Land, Japan).
· · Mills usually have motors in the following range: SAG mill motor: 7,435 kW or an HPGR circuit with motors: Ball mill 1 (4,015 kW) and Ball mill 2 (4,152 kW) for a porphyry copper molybdenum mine. Comparing mill operations for both open pit mining to underground mining, where the metal is separated from rock ore containing the metal mined, both open pit and underground mining .

· In this study, highenergy ball milling was applied to synthesis in situ nanostructured copper based composite reinforced with metal carbides. Cu, M (M=W or Ti) and graphite powder mixture were mechanically alloyed for various milling time in a planetary ball mill with composition of Cu20vol%WC and Cu20vol%TiC. Then the asmilled powder were compacted at 200 to 400 MPa and .
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
