Wet grinding equipment – sand mill
Horizontal sand mill
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.
Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic
Among the sand mills, the most common is the horizontal sand mill, which is a horizontal disperser for continuous wet production of ultrafine powder. The operation process is to use a high-viscosity pump, such as a gear pump, to input the well-mixed material into the grinding chamber of the main machine. The grinding chamber is filled with an appropriate amount of grinding media, such as glass beads, and zirconia beads. The grinding medium of the sand mill is driven by the grinding disc and the dispersing disc and is dispersed under the action of shearing force. Grinding media and dispersions are separated by dedicated separation devices and discharged separately. Consistent and excellent dispersion quality enables continuous production as operating skills are not as demanding as three roll mills, and sand mills are used to improve quality and reduce costs, as well as disperse high-viscosity materials such as varnishes, inks, dyes, correction fluids, materials in the cosmetic, pesticide, electronics and paper industries.
In the chemical industry, dispersion engineering has always been an important process. It is widely used in coatings, varnishes, inks, dyes, printing and dyeing, pesticides, and other fields. Dispersion is the function of dispersing solid particles into a liquid medium and consists of three steps:
1. Wetting
Replace all absorbed gas on the surface of solid particles with liquid.
2. Grinding
The solidified particles are broken down into original particles by mechanical separation power.
3. Decentralization
Transfer the wetted virgin particles into a liquid medium to permanently separate the particles.
Nano sand mill adopts double-end mechanical seal as a pressure resistance device, conical grinding cavity, and gap stirrer; click and install under the frame, and ensure energy transmission through a v-shaped belt; the processing area of the sand mill is small, which can reduce the cross-contamination of products; the grinding chamber is made of high wear-resistant materials; the control panel is integrally embedded in the machine frame. The production capacity of the nano sand mill is high.
The horizontal sand mill is a multi-layered disc with a rotating spindle in the barrel; the barrel part is equipped with a cooling or heating device; the qualified slurry flows out through the filtration gap or sieve hole smaller than the particle size of the grinding medium; zirconia beads are used as a grinding medium, zirconia beads have high hardness and are easy to clean; the horizontal sand mill has the function of dispersing and mixing, and is suitable for grinding dyes, pigments, paint coatings, pharmaceuticals, and other suspensions or suspensions.
Different sand mills have different structures, but the final production results are the most satisfactory among the grinding equipment.

Guidelines For Sand Mill
The sand mill mainly uses friction, shearing, and collision as effective grinding methods. It is one of the grinding equipment currently applicable to a wide range of material particle sizes and has high grinding efficiency. The energy density per unit volume is large. The control system can complete the continuous grinding and continuous discharging of the slurry, which greatly improves the production efficiency of the sand mill. It has the advantages of high energy density, fine product granularity, small environmental pollution, simple equipment structure, and convenient maintenance.
Sand Mill: Enhancing the Efficiency of Grinding & Dispersion
Sand mills, also known as bead mills or media mills, are mechanical devices used in the field of grinding and dispersion.
Instructions for use of vertical sand mill
The vertical sand mill is a nano-sand mill whose grinding cylinder adopts a suspended structure, raw materials enter from the bottom and discharge from the top.
How to choose the right vertical sand mill & horizontal sand mill?
Vertical sand mills and horizontal sand mills are commonly used equipment for grinding in paint, coating, ink, and other industries. They all rely on the high-speed rotation between the grinding medium and the material for grinding work.
How to deal with the problem of sand mill?
The sand grinding machine, also known as the pearl grinding machine, is used to grind the paint of the pigment with hard wear -resistant beads, glass balls, etc. in a closed cavity.
How to choose a sand mill for paint?
Sand mills are mainly used in industrial fields such as paint coatings, cosmetics, food, daily chemicals, dyes, inks, pharmaceuticals, magnetic recording materials, ferrites, photosensitive films, oxide ceramics, and new energy.
Grinding media for sand mills
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.
