The ball mill has low energy utilization efficiency. At present, there is a tendency to replace ball mill with vertical mills and roller presses, but the ball mill has the advantage that the particle shape is approximately spherical, which is conducive to raw material calcination and cement hydration hardening.
According to what the experts said, vertical grinding mill machines have such advantages as the following. Process flow of vertical mill system is simple. And construction area is small, which covers an area of about 70% of the ball mill system, which directly reduce the enterprise investment costs.
The grinding product of grid ball mill is discharged from the ore discharge grid plate, which has the effect of forcing ore discharge. The ore discharge speed is fast, and the level of the pulp surface at the end of ore discharge is lower than the lowest horizontal line of the shaft neck of ore discharge, so it is called horizontal ore discharge.From the feeding end to the discharging end of the pulp surface in the mill,
1. 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".
2.High Efficiency: with the same powder fineness process the YGM vertical Raymond mill capacity is as 2-3 times as much that other model grinding mills, the vertical roller mill not only has a high capacity, it also energy saving, the electronic consume can reduce 30% when we compare it with other grinding mill;
Vertical roller mill grinding speed is slow, so the Vertical roller mill powder grinding capacity is small. In other words, when the material contains relatively large amount of water, the material in the vertical mill machine will be prone to adhesion, but also very easy in the delivery of the material during the blockage.
