Mill is the energy consumption the power supplied to the mill is used primarily to lift the load medium and charge additional power is required to keep the mill rotating 813 power drawn by ball semiautogenous and autogenous mills a simplified picture of the mill load is shown in figure 83 ad this can be used to establish the essential
Ball end mills have a rounded nose and create a roundbottomed groove in milling tasks also known as ballnose end mills they are rotated against a workpiece to make roundbottomed slots and pockets or mill complex shapes without sharp corners
Mill power usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level it is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration figure 2 shows that there is no linear relation between
Ballmill base with ventilated motorcover installed ballmill base with ventilated motorcover removed the ballmill drive system looking inside the mills motor compartment you can now see the motor with a small fan and pulley on its shaft that small pulley is connected by a drive belt to a large pulley which is mounted on the units drive
The size of feed particles to a rod mill is coarser than for a ball mill the usual feed size ranges from 6 to 25 mm the speed of rotation of the mill influences the power draw through two effects the value of n and the shift in the center of gravity with speed the center of gravity first starts to shift away from the center of the mill
