The application of sand mills has been very extensive. With the development of society and the advancement of science and technology, sand mills also have great technical updates and innovations to meet the needs of different users.
When using the sander to grind daily, it is inevitable that you will encounter some common problems. What are the main factors that affect these? In fact, there are three major factors that affect the working efficiency of sand mills. That is to say, the three major factors affecting the operation of the sand mill are: the three main influencing factors of the speed of the stirring shaft, the temperature of the cooling water, and the grinding medium.
The influence of the stirring shaft speed of the sand mill on the grinding efficiency. The speed of the stirring shaft of the sand mill plays an important role in the grinding efficiency. The dispersive grinding action of the sand mill is mainly based on the shear force and the friction force. The greater the rotation speed of the stirring shaft, the greater the centrifugal force obtained by the grinding medium, the greater the speed difference between the grinding media, and the shear and friction forces. The larger the linear velocity of the rotor, the less the grinding time required to reach the required percentage of particle size. Therefore, from the perspective of improving the grinding efficiency, increasing the rotation speed of the stirring shaft has the effect of improving the grinding efficiency, but the increase of the rotation speed is limited by the mechanical strength and hardness of the materials such as the grinding medium, rotor, and stator. Therefore, it is advisable to select 9 ~ 15m / s for the linear velocity of the agitator shaft wing end.
The influence of the cooling water temperature of the sand mill on the grinding efficiency. The temperature of the cooling water directly affects the working temperature in the grinding chamber, thereby affecting the grinding efficiency.
The influence of the grinding medium of the sand mill on the grinding efficiency. The influence of the grinding medium on the grinding efficiency includes the influence of the specific gravity of the grinding medium, the diameter of the grinding medium and the filling rate of the grinding medium on the grinding efficiency. The larger the specific gravity of the grinding medium, the greater the energy it obtains, the impact and shear forces will increase accordingly, and the grinding efficiency will increase. The smaller the diameter of the grinding medium, the smaller the gap between the grinding media, and therefore the It has a too large area of dispersion grinding, and limits the aggregation of materials, thereby improving the efficiency of dispersion grinding. The larger the filling rate of the grinding medium, the greater the contact frequency of the grinding medium, and the greater the dispersing and grinding ability.
The above are the three main factors that affect the efficiency of the sand mill.
