Grinding Mill Foundations

Sep 23, 2014· Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by

Ball Mill Explain What Is Ball Mill Prototype Ball Mill Ball mill operating principles components uses a ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy of the mill volume and

What's the Difference Between Ball Mills and Rod Mills

Nov 19, 2019· The rod mill adopts overflow type and open type discharge, does not use grate type discharge The diameter of the rod mill discharge end is larger than that of the same size ball mill When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state

Ball Mill vs Rod Mill | How To Choose Ball Mill or Rod

The rod mill usually uses 50100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium The length of steel rod is 2550mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 08% – 1%; the loading capacity of rod is about 35% – 45% of the effective volume

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 The tumbling and rolling rods expend most of their crushing force
