Jan 7, 2015 . 2.0 Diameter & Length of Mill: The diameter and the length of a tube mill depend on various factors. the most important factors are capacity, hardness of the material, feed size, fineness of the finished product, open or closed circuit grinding, and grinding system. The capacity of the mill depends on the cross.
A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The rawmilling stage of the process effectively defines the chemistry (and therefore physical.
Can anyone tell me what are the requirements for ball charge design of a mono-chamber raw mill? How can you calculate . Thanks for your reply. There is a hammer crusher before the raw mill so mill feed is very fine with d80 (80% passing size) of 4000 micron and 1% passing 3/8 mesh (9.5 mm sieve).
Due to the compact design and material transportation system of vertical roller mills (VRM), some important streams (total mill feed and discharge, dynamic separator feed and reject) remain in the mill casing. This situation leads to sampling problems around the equipment. This paper discusses a new simple sampling.
