What is a bead mill?
A Bead Mill also known as a sand mill, is mainly used for the wet grinding of chemical liquid products. Compared with grinding equipment such as ball mill, roller mill, and colloid mill, bead mill has the advantages of high production efficiency, strong continuity, low cost, and high product fineness. The process conditions vary greatly, and the fineness requirements can be adjusted and classified by adding or subtracting grinding media in an appropriate amount.
1. The medium distribution in the grinding chamber of the horizontal large-flow bead mill is relatively uniform, the grinding technology has high efficiency, it is very easy to start with load, and the operation is simple and convenient. It can be designed to be large or super large. However, the energy density (installed power per unit volume) is low and the grinding fineness is limited.
2. The medium distribution of the vertical bead mill is uneven, the efficiency of grinding technology is low, and it is difficult to start the capital with the load. The advantage is that there is no mechanical seal and the structure is simple.
3. The energy density of the conical bead mill, short cylinder grinding, a large area of filter media separation, the short residence time of materials, high cooling effect, high grinding efficiency, and narrow product size distribution. Generally, it can be used for the circulating grinding process with the large flow of difficult-to-grind materials.
4. High viscosity rod pin bead mill has high energy density and high strength of grinding material. Mainly used for the production of high viscosity materials, such as offset printing ink and UV ink.

The ointment mills are largely used by the pharmaceutical industry, where color changes and smaller batches are needed. The mills use a strong shear force for dispersing active ingredients, and the ointment mill is popular due to its perfect cooling surface and temperature control.
The kneader for the dispersion process is supplied by the manufacturers offered uniformity in the compound that is being dispersed along with the fast washing of the product for the adjustment of color.
Sand mill is a kind of high-efficiency grinding equipment, which is mainly used for grinding materials, and the particle size of the final grinding can reach the nanometer level.
Horizontal sand mill is suitable for grinding and creating medium-viscosity liquid materials such as paints, inks, pigments and dyes, medicines, cosmetics, food, papermaking, electronic materials, etc. Horizontal sand mills are suitable for high viscosity, small fineness, volatile materials, and closed grinding.
Sand mill is an indispensable piece of equipment in the coating industry and chemical industries. It can not only be used to grind products with large particles, but also very fine products, which can reach the nanometer level at least.
Nano sand mill is a new type of grinding equipment, mainly used in carbon nanotubes, nanomaterial pigments, nanocoatings, inks, inkjet inks, cosmetics, food, proteins, lithium batteries, functional ceramics, photovoltaic materials, and other fields.
