VRM vs Ball Mill for Cement Grinding Page 1 of 1 10 02 2016 re VRM vs Ball Mill for Cement Grinding Specific power consumption high for ball mill and Low for VRM Maintenance costs high for VRM and low for Ball mill Process controlprocess technology ball is operation friendlt and simple in operation but VRM requires some PID or control.
A ball mill is a horizontal cylinder filled with steel balls or the like This cylinder rotates around its axis and transmits the rotating effect to the balls The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.
Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant This helps to reduce cost and complicated logistics issues The equipment cost is however higher for a VRM than a ball mill So these are the pros and cons of the two technologies and a cement manufacturing company.
Jun 05 2019 The ball mill not only has high investment cost but also large energy consumption The power of the ball mill directly affects the level of energy consumption Under the premise of ensuring the output controlling the power of the ball mill within the rated range is the most important thing to save energy and reduce consumption and save cost.
