(1) The power consumption level for grinding is lower than that of tube (ball) mill. (2) The remaining time of raw materials in this type of mill is much shorter than that in tube (ball) mill; therefore, the crushing process and mixing process became more harmonized and this contributes to quality control.Get Price

Introduction To Strainer In Piping The Process Piping
Strainer uses a perforated plate or screen mesh to remove larger particles from a process stream. the major advantage of a strainer is that it is reusable. the filter screen is only used once and must be changed when it clogs. the main difference seems to be in diameter of the holes in the media screen also termed as mesh size in case of strainer.
Factors Affecting Ball Mill Grinding Efficiency
A) mill geometry and speed – bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. as well, mills with different length to diameter ratios for a given power rating will yield different material.
