Nano sand mill is one of the important equipment for the preparation of fine materials. It is also called bead mill or ball mill abroad, also known as stirring ball mill (a combination of stirring shaft ball mill). In principle, whether it is a ball mill, a nano-sand mill or a mixer, the grinding medium is used to provide sufficient kinetic energy for the dispersion blades under the action of high-speed rolling, so that the impact and extrusion between the grinding media and the shearing force generated by the grinding material play the role of grinding.
Nano sand mill is a new type of grinding equipment. Choose high precision double inner hole machine seal, grinding material is less. The raw material enters the crushing chamber from the top by a feed pump. During the entire process of obvious milling, the bar pin and the motor stator continuously collide strongly with the milled material, and then the milled material is applied to the raw material. These materials have been completely ground. At the discharge port, due to the different density, the grinding medium returns to the grinding chamber, but the material flows out of the grinding chamber through the gap separator under the pressure of the feed pump. Mainly used in carbon nanotubes, nano material pigments, nano coatings, inks, inkjet inks, cosmetics, food, proteins, lithium batteries, functional ceramics, photovoltaic materials and other fields.
Nanomaterials refer to materials with at least one-dimensional nanometer size (0.1-100 nanometers), or materials with three-dimensional space formed by them as basic units, which is equivalent to the size of 10-100 atoms packed closely together. Nanomaterials exhibit many unique properties, and their optical, thermal, electrical, magnetic, mechanical, and chemical properties are significantly different from those of large solids. Most nanomaterials are made by chemical methods. The preparation of nanomaterials by mechanical grinding has received widespread attention due to its low cost and large-scale production. Once a major breakthrough is made in this field, the production of nanomaterials will enter a new stage.
