[0002] Sand mill is the most adaptable, most advanced and most efficient grinding equipment. It has the narrowest grinding chamber, the smallest lever gap and the most intensive grinding energy. Combined with a high-performance cooling system and automatic control system, it can realize continuous processing and discharging of materials, greatly improving production efficiency.

[0003] When the sand mill is grinding the material, generally the single cylinder receives the material and then enters the grinding barrel. During the cycle grinding, the material circulates between the grinding barrel and the material receiving cylinder. The material enters the grinding barrel from the material receiving cylinder, and after being ground in the grinding barrel, the material flows into the material receiving cylinder again. At this time, there are materials of different sizes in the material receiving cylinder, and they are directly discharged into the grinding barrel for grinding. When the materials of different sizes are ground at the same time, some of the materials will be over-ground, resulting in poor grinding effect, and the grinding times of the materials in the grinding barrel are not the same.
