Sand mill, also known as bead mill, is mainly used for wet grinding of chemical liquid products. According to its performance, it can be divided into vertical sand mill, horizontal sand mill, basket sand mill and rod sand mill. machine etc. It is mainly composed of machine body, grinding drum, disperser, bottom valve, motor and feeding pump. The speed of feeding is controlled by the valve. With only the composition classification of the sand mill, what is the working principle of the sand mill?

How does a Lab Basket Sand Mill Machine work?

The working principle of the sand mill is to use the material pump to feed the solid-liquid phase mixture material after pre-dispersion and wetting treatment by the mixer into the cylinder, and the material and the grinding medium in the cylinder are stirred by the high-speed rotating disperser, so that the material in the material is stirred. The solid particles and the grinding medium produce more intense collision, friction and shearing effects with each other, so as to achieve the purpose of accelerating the grinding of fine particles and dispersing aggregates. After grinding and dispersing, the grinding medium is separated by a dynamic separator and flows out from the discharge pipe.

The influence of the working parameters of the sand mill on the grinding material, the flow of the sand mill affects the product fineness, output and particle size distribution. Media size affects grinding efficiency and product fineness. The speed of the stirring axis affects the grinding efficiency, material fineness and wear. The specific gravity of the medium affects the grinding efficiency and product fineness. The media filling rate affects the grinding efficiency and product fineness.

The main structure of the Lab Basket Sand Mill Machine

The sand mill is mainly composed of a body, a grinding cylinder, a sanding disc (lever), a grinding medium, a motor and a feeding pump. The grinding medium generally uses zirconia beads, glass beads, zirconium silicate beads, etc.

What is the grinding fineness of nano sand mill?

The grinding fineness of the sand mill is a parameter that everyone is more concerned about. Some products require high grinding fineness, so a nano-sand mill is used. So what is the grinding fineness of the nano-sand mill? Can a nano-sand mill grind nano-scale products?

It is understood that although the nano sand mill is called nano, it cannot grind nano-level powder or nano-level materials. Its grinding fineness is relatively small, and the smaller particles are close to 100 nanometers; of course, due to the physical properties of the material The situation is different, and the grinding fineness that each material can achieve is also different.

Application of Lab Basket Sand Mill Machine

Sand mill is a kind of high-efficiency grinding and dispersing equipment widely used in paint coatings, cosmetics, food, daily chemicals, dyes, inks, medicines, magnetic recording materials, ferrites, photosensitive films and other industrial fields. Compared with grinding equipment such as ball mill, roller mill and colloid mill, sand mill has the advantages of high production efficiency, strong continuity, low cost and high product fineness. Therefore, it is widely used in coatings, dyes and other industries.
