Grinding raw material and clinker causes considerable wear to the grinding mill. Starting the mill directonline stresses the mill and the gearbox, increasing the risk of gearbox failure and shortens the lifetime of mechanical equipment. VSDs help optimize the mill speed to match the material flow, thus minimizing the wear of the grinding mill.

23/01/2014· The line has a lot of cyclones and there are two strings. The gas is parallel but the material jumps around through six cyclones in each string. It is relatively complicated but it was built in that way to bring down the specific heat consumption. The original design had an exhaust temperature of less than 300°C, very low indeed. With the

01/05/2011· Specific energy consumption in cement production varies from technology to technology. The dry process uses more electrical but much less thermal energy than the wet process. In industrialized countries, primary energy consumption in a typical cement plant is up to 75% fossil fuel and up to 25% electrical energy using a dry process. Pyroprocessing requires the major share of the

The vertical mill has no direct contact between the metals in actual use, so the metal consumption is less, and the wear of the accessories is less and the service life is longer; In addition, the ball mill consumes a large amount of collision friction in order to achieve a good grinding effect. In use, it can also be found that the vertical mill with the best supply and sales can grind and

The energy consumption rate of the ball mill is relatively low. At present, there is a tendency to be replaced by vertical mills, roller presses, etc., but the ball mill has a "granular shape that is approximately spherical, which is conducive to raw material calcination and cement hydration hardening". The unique advantage is that this is the main reason why clinker mills still use ball
