The laboratory sand mill, also known as the laboratory sand mill, is a kind of grinding equipment relative to the sand mill for industrial production. The working principle is the same as that of the sand mill for industrial production. A grinding cavity with a rotor, the grinding cavity is filled with a certain amount of grinding medium (grinding beads), and the material collides, squeezes, stirs and mixes with the internal grinding medium through the rotating rotor to achieve the effect of slurry crushing and refining. A grinding device.
Compared with the sand mill for industrial production, it has the characteristics of small size, compact structure, low power, light movement, convenient disassembly and assembly, relatively small output, low noise and low price. The biggest difference from the sand mill for industrial production is the volume of the grinding chamber. The volume of the grinding chamber of the laboratory sand mill is as small as 0.1L, as large as 10L and 15L.
The main types of laboratory sand mills are similar to those used in traditional industrial production.
According to the installation structure, there are: vertical, horizontal, etc.;
According to the rotor structure inside the grinding chamber, there are: blade type, rod-pin type, turbine type, turbine rod-pin type, etc.;
According to the internal material of the grinding cavity, there are: alloy steel type, tungsten steel type, ceramic type, hard plastic type, etc.;
According to the grinding fineness, there are: nano-type (grinding particle fineness below 100 nanometers), non-nano-type, etc.;
Main application fields of laboratory sand mill
Since the output of laboratory sand mills is smaller than that of industrial sand mills, this equipment is generally used in institutions with a small amount of grinding occasions, such as institutions of higher learning, chemical industry, electronics, medicine, coatings, paints, inks and other related industries. laboratories, research institutes, etc.
