Horizontal bead mill is a high-efficiency wet ultra-fine grinding and dispersing machine widely used in non-metallic mineral industries such as coatings, dyes, paints, inks, medicine, magnetic powder, ferrite, photosensitive films, pesticides, papermaking and cosmetics. . Horizontal bead mills can be divided into ordinary horizontal bead mills, wheel-pin horizontal bead mills, toothed disc horizontal bead mills and turbo-type horizontal bead mills according to different structures.

Types of bead mills

High-speed bead mill is mainly used for grinding and manufacturing medium and high viscosity liquid raw materials such as paints, inks, pigments and adhesives. Mainly include basket bead mill, horizontal bead mill, three-roll bead mill and vertical bead mill.

Basket bead mill

Coating slurry pre-dispersion and grinding and dispersion can be carried out in the movable tank with inclined bottom, no need for conveying equipment, less auxiliary equipment, easy cleaning and color change, especially suitable for small batches of various types of paint grinding, low speed, stable operation, Intermittent production, the basket wear is large, the manufacturing is difficult, but the paint loss is small. It is a relatively advanced paint bead mill.

Horizontal bead mill

The operation procedure is that the liquid raw material is transported by the pump into the closed grinding cylinder, and then the main machine pushes the meson grinding beads to run at a high speed, so that the coating material is pressurized and rotated at a high speed in the narrow grinding bead gap, resulting in mixing, emulsification, dispersion, and rubbing. Kneading, rolling and other submerged functions are used to achieve the required fineness of the raw materials. After grinding, the hard tungsten steel separation gap rotating at a high speed is output to the outside of the grinding cylinder. It is a one-time cycle grinding operation, and the continuous cycle grinding fineness can reach below 5μm. It is the main recommended equipment in paint bead mills.

Vertical bead mill

The vertical bead mill is easy to operate, large in production capacity, easy to change color, and easy to maintain; the separation device is a screen, overflowing material, normal pressure operation, can not use finer grinding media, and the filling amount is also small, only suitable for low viscosity, Dispersion and grinding of the paint slurry with good flow; slightly high temperature operation, serious solvent volatilization, easy skinning of the screen, low grinding fineness; small slurry dispersion area, large retention area, large power consumption, and low dispersion efficiency. Seed bead mills are currently used more.

High-speed bead mills are widely used in paint coatings, cosmetic raw materials, food, daily chemicals, dyes, inks, medicines, pesticides, magnetic recording materials, ferrites and other industrial fields, and are extremely important chemical equipment. Shanghai Sower Group has more than ten years of experience in the field of chemical equipment manufacturing, and has a deep understanding of the needs of the owners. It can provide bead mill products of various specifications to meet the production needs of the owners.

Three-roll bead mill

The three-roll bead mill achieves the grinding effect of coating raw materials through the mutual extrusion of the surfaces of the three horizontal rollers and the friction at different speeds. It is especially suitable for the grinding of high viscosity, small batch materials and materials that are difficult to recycle or not resistant to recycle by bead mills, such as various color pastes, inks, etc.

Nano bead mill

For wet dispersing and grinding of connected dispersing and pumpable materials, grinding products of different viscosities to the micro and nano scale. The use of all-ceramic structure and high-quality materials (yttrium-stabilized zirconia, silicon carbide, ultra-high polymer materials) ensures no metal contamination and longer life, while the high hardness properties of ceramics can also make the product more refined.

The patented turbo disperser ensures high-energy uniform movement of the grinding beads, guaranteeing high efficiency. Efficient energy conversion effectively reduces energy consumption. The patented sheet-type separation screen ring structure and its special non-blocking design can use 0.1mm~1mm grinding beads, with high separation reliability, safety and convenience, and simple maintenance. Channel-type and circulating-type production process, continuous high-efficiency achieves the narrowest particle size distribution. Easy to clean, only a small amount of solvent cleaning medium is required. The ideal cooling effect ensures smooth grinding of temperature-sensitive materials. The optimized design is more convenient to operate.

The intelligent operating system records operating parameters more scientifically and ensures the smooth implementation of production. The high-efficiency and large-flow rotor separator system is 5~10 times that of ordinary bead mills.
