Ball mill consist of a hollow cylindrical shell rotating about its axis Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of Steel Stainless steel or rubber Inner surface of the shell is lined with abrasion resistant materials such as Manganese Steel or rubber Length of the mill
Formula to Calculate TCP throughput 1 1 hi all Throughput = TCP maximum receive window size / RTT I have some question regarding this Throughput = amount of data transferred over a given period of time so if more data transferred - higher throughput
Replacing traditional steel cast mill liners with new lightweight composite liners is another way to increase throughput of mills Major gold and copper operations have already started doing this in mills up to 40' and seen an improvement in the slurry discharge of up to seven percent
a semi-autogenous (SAG) mill AG/SAG mills are often used as the first stage in a two- or multiple-stage grinding process where the second stage is carried out by the ball mill but they can also be used as a one-stage grinder The absence of or reduction in the number of balls means they can be less costly to operate than ball mills
27-10-2019This signature could be effectively used to optimize the milling performance by investigating this signature's relation to mill product size mill throughput make-up ball size mill speed liner profile and ball addition rates At the same time it can also be used to design balls and liner systems that can survive longer in the mill
and ball mills have almost become power-based equations remain the principal method for designers to size mills and estimate the power requirement for comminution circuits The desired throughput of the mill is multiplied by the specific energy to give the mill power requirement which is used in turn to size a mill for dimensions
