ball mill vs rod mill in mexico

Dec 30 2019 · The power consumption of the ball mill is slightly higher than that of the rod mill and the wear rate is also higher than that of the rod mill The daily maintenance requires constant addition of a certain amount of steel balls while the rod mill only

Grinding medium of rod mill The rod of diameter from 50 to 100 mm is often used as the grinding medium and the filling rate of rod mill is 35 to 45 while filling rate of ball mill is 40 to 50 Rod is mainly made of several materials A High carbon steel

When the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length New feed entering at one end of the mill causes the rod charge to spread at that end This produces a series of wedge shaped slots tapering toward the discharge end The tumbling and rolling rods expend most of their crushing force on the

Compared with the ball mill the rod mill adopts advanced controllable feeding and discharging technology and can use the appropriate grinding body according to the grinding material The point contact of the traditional ball mill can be changed into line contact which can make the discharge granularity more uniform and the output is higher

The rod mill usually adopts the steel bar with a diameter of 50100mm as the grinding medium while the ball mill often uses steel ball as the grinding medium The difference on grinding medium is the main difference between the ball mill and rod mill

In rough grinding when the output size is 13 mm the processing capacity of the rod mill is greater than that of the ball mill of the same specification when used for fine grinding the particle size of the product is less than 05 mm the grinding effect of the rod mill is far inferior to the ball mill with same specification

Jun 11 2019 · In the order you have listed a ball mill can fine grind down to 400 mesh if needed a rod mill will efficiently grind to 150200 mesh range and a roll mill can do a 100 mesh The ball and rod mills are similar in appearence as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium

Ball mills Ball mill Fig 1 is same kind of mill as rod mill except that it is filled with balls instead of rods Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding Balls are also lighter so the kinetic energy of a single dropping ball is smaller than a rod

With slightly larger barrel volumes than the Essa ball mill series rod mills are ideal for larger and more coarse materials Rod charges and an acoustic safety enclosure for the

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore The rod charge must be maintained in good working condition and broken and worn rods must be removed Rod mills usually require greater operator attention It is important

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 AGSAG mills can acplish 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

Ball Mills vs Rod Mills When the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length New feed entering at one end of the mill causes the rod charge to spread at that end This produces a series of wedge shaped slots tapering toward the discharge end
