When using grinders in everyday life, it is inevitable that you will encounter some common problems. What are the main factors affecting these problems? In fact, there are three main factors that affect the efficiency of a grinding machine. In other words, the three main factors that affect the work of a grinder are: stirring shaft speed, cooling water temperature and grinding media.

The influence of stirring shaft rotational speed on grinding efficiency. The stirring shaft speed of sand mill has an important influence on the grinding efficiency. The dispersion and grinding function of sand mill is mainly shear force and sudden friction. The greater the stirring shaft speed, the more centripetal force the grinding media obtains, the greater the speed difference between the grinding media, the greater the shear force and friction, the greater the rotor angular velocity, and the lower the grinding time required to reach the required particle size percentage. Therefore, from the point of view of improving the grinding efficiency, increasing the speed of the stirring shaft has the effect of improving the grinding efficiency, but the increase of the speed is limited by the mechanical strength and hardness of the grinding media, rotor, stator and other materials. Therefore, the stirring shaft wing end line rate should be 9~15m/s.

The effect of cooling water temperature on grinding efficiency. The cooling water temperature directly affects the working temperature of the grinding chamber, which in turn affects the grinding efficiency.

The influence of grinding media on grinding efficiency. The influence of grinding media on grinding efficiency includes the proportion of grinding media, the diameter of grinding media and the filling rate of grinding media on grinding efficiency. The larger the proportion of grinding media, the greater the energy, the greater the impact and shear force, the higher the grinding efficiency; the smaller the diameter of the grinding media, the smaller the grinding media gap, the more dispersed the grinding area, limited material aggregation, improve the efficiency of dispersion grinding. The higher the filling rate of grinding media, the higher the contact frequency of grinding media, the stronger the dispersion and grinding ability.
