1、Low temperature working condition requirement

According to the dispersion mechanism of nano sand mill, when the beads and particles in the grinding chamber collide and rub against each other, high heat will be generated. If the heat can not be taken away in time, the material will be agglomerated again at a higher temperature, thus failing to meet the requirements of nanometer fineness.

2、No pollution conditions

According to the dispersion mechanism of the sand mill, when the microsphere in the impact and friction of solid particles, the grinding chamber and stirring device in the cavity of the wear and tear damage intensity is also very large, so that the cavity and stirring element of the material to have anti-wear; otherwise, due to wear and tear of the raw material contaminated, so that the equipment has a shorter service life, and it is important to pollute the source of the dispersed raw materials to be agglomerated again, and can't have the nanometer fineness and the requirements of the normal distribution.

3、The use of high-flow grinding and dispersion process

The use of a bead-liquid separation device, to recognize that the beads can not block the separator, and to make the flow through the separator of the liquid paddle through the separator, so that the size of the raw material particles can not be smaller in the crushing chamber to absorb too much impact energy, agglomeration, and to reduce the temperature of the grinding and dispersing chamber.

4、The use of small-sized microbeads

The smaller the number of microballs used in the sand mill of the same particle size, the greater the number of microballs entering the sand mill, the greater the geometric multiplicity of contact points, and the higher the grinding and dispersion efficiency.
