Sand mill in the grinding process, in addition to grinding the size of the particle size and other factors widely concerned, how to control the sand mill feed rate, to ensure that the amount of material can be ground to reach a larger value, thereby improving the efficiency of the feed is also very important point.

First of all, we adjust the sand mill feed rate is a more common way to adjust the feed valve way to realize. Each sand mill will be equipped with a special feed valve, through the opening and closing to play a role in controlling the speed of the material feeding process, increase or open the valve size can increase the feed rate, reduce or close the valve can reduce the feed rate.

Secondly, you can adjust the diameter of the feed pipe mouth to adjust the feed rate, equipment feed pipe mouth is too small will let the material through the speed of a greater impact, matching a sand mill and a suitable feed pipe mouth is particularly important, by adjusting the small pipe mouth to a larger pipe mouth, you can make the feed rate to be effectively increased.

At the same time can not be ignored is that the rotational speed of the sand mill is a great influence on the feeding speed, because the sand mill itself in the rotation process in the cavity is the existence of a certain pressure, when the rotational speed increases the pressure in the cavity increases, the material emptying speed will be accelerated, making the cavity to produce differential pressure, thereby accelerating the speed of the material into the sand mill, so when the rotational speed of the sand mill increases can significantly improve the sand mill So when the rotational speed of the sand mill is increased, the feeding speed of the sand mill can be significantly increased.

Flexible adjustment of the temperature of the sand mill can have a significant impact on the feed rate of the sand mill, because the increase in temperature to a certain extent can accelerate the crushing rate of the material particles, grinding in the collision of particles, shear, impact speed will also be greatly accelerated, the particle size of the material to reach the intended discharge particle size of the time can be relatively shortened, the speed of the discharge can be significantly improved, when the discharge speed is accelerated, it will let the material to Faster speed into the cavity, thus playing the effect of increasing the feeding speed.
