re vibration vertical roller mill. Hello Ashkan, The most important factor which determines the level of vibration in a VRM is the thickness and consistency of the grinding bed. The bed thickness may be affected by the following variables;-Feed rate too low, too high or changing too quickly. Particle size of feed too large or too small.

Due to the vibratory disc mill's geometry, only the grinding disc's vertical variation could be recorded because the necessary continuous contact between the grinding body and the position sensor could only be ensured for this centred position, see Fig. 2. In contrast, the grinding ring's vertical variation could therefore not be measured.

It can be known from the working principle of the mill that the vertical mill grinds the material by applying pressure from the grinding roller when it is working. After a long time of operation, the grinding rollers and grinding discs become uneven and irregular due to abrasion, the grinding efficiency decreases, and the output decreases.

Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..
