The ball mill is the usual generally cylindrical drum having an end wall 21 provided with an axially extending hub 22 rotatable in bearings 23 on a base 24.
Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution discharge mills give a final product in an open circuit.
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to

2. Dry Type Ball Mill: Some discharge materials are extracted by air flow, and the mill and wind grading device are closedcircuit. For example, cement mill adopts automatic discharge. (7) Types on the Basis of Cylinder Direction. 1. Vertical Ball Mill: The vertical ball mill is a new type of ball mill which places the cylinder upright. Through ...
Most discharge via trunnionoverflow; Volumetric loading is similar to that of a ball mill (3035%) Design standards for drive components are more demanding than ball mills; Dry applications feature a peripheral discharge or an airswept arrangement; Typical operating speeds are slower than either SAG or ball mills: 6570% TCS (wet) and 6263% ...
While there are several types of ballmill on the market, particular attention will here be given to the diaphragm type (Peripheral Discharge Ball Mills ), as the opentrunnion type, especially the conical mill, has been thoroughly discussed here.
Overflow discharge rod mills are available from 75 to 2,000 hp ( 56 to 1,490 kW ), while overflow discharge ball mills ranging from 75 to 8,000 hp ( 56 to 5,970 kW ) are included in the standard wet grinding line. For dry grinding, peripheral discharge rod mills and grate discharge ball mills are available for special applications.

OUTOTEC GRINDING TECHNOLOGIES BENEFITS • Improved performance, safety, and ... Ball mills Ball milling is the most common application for horizontal tumbling mills. Outotec offers a full range of ball mills to ... Discharge arrangement Overflow, peripheral, grate and openended discharge options are available. SAG and AG mills typically have
Continuous Rod and Ball Mills Sepor. Optional peripheral discharge is for coarse grinding with minimum production of fines or slimes. Flexible for wet or dry grinding in open or closed circuit as a rod, ball or pebble mill and as an overflow or peripheral discharge rod mill. Advantages.
The peripheral discharge type of BallRod Mill is a modification of the grate type, and is recommended where a free gravity discharge is desired. It is particularly applicable when production of too many fine particles is detrimental and a quick pass through the mill is desired, and for dry grinding.
Peripheral Discharge Ball Mill; Rod Mill; The TITAN designed Girth Gear, Bearing system Drive housing. Fits the flanged drive motors (IP66 Premium efficiency) to align as the drive housing selfaligns with the shell. Runs with a single lubrication system, responsible for both the hydrodynamic lift and gear system lubrication.
End Peripheral discharge and center peripheral discharge rod mills are described in detail on pages 28 and 29. Feed and discharge heads of Rod Mills are conical in shape providing important advantages over a mill with straight heads. 1. They provide the essential feed pocket and also a space for the pulp to squeeze from the rod mass.
According to their different discharging end, ball mills can be divided into three types: grid type, overflow type, and peripheral discharge type. In practice, peripheral discharge ball mills are rarely used; while grid ball mills and overflow ball mills are commonly adopted.
has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications. Some of those applications are grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high temperature milling oprations and more.
The Rod Mill is the same as the Ball Mill in the construction and available to both of wet and dry processing. Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill.
The center peripheral discharge rod mill is also used for wet grinding but produces a coarser product than the overflow the end or center peripheral discharge rod mill can be used for wet or dry the type, the rod mill is used to produce a coarse product, whereas the ball mill is used to produce a finer product.
