Working principle of sand mill

Important feature
Completely enclosed. Due to the completely enclosed dispersion chamber, there is no air mixed in, preventing the generation of bubbles and solvent evaporation through a gap separation and discharge device. It can use extremely small grinding media, with high grinding efficiency and good product fineness.
The material has a short residence time in the grinding cylinder, a large circulating flow rate, and good heat dissipation performance, making it suitable for grinding heat sensitive products. The shaft can be cooled, with excellent heat dissipation performance, and the product fineness can reach the nanometer level. The front mounted filter greatly reduces axial pressure and extends the service life of the shaft seal. Variable frequency speed control motors can be used to adjust the speed of the disperser without the need for anchor bolt installation.
Applicable scope of horizontal Sander
The horizontal Sander is applicable to paint, ink, pigment and dye, medicine, cosmetics, food
Grinding and manufacturing of medium viscosity liquid raw materials such as paper making and electronic raw materials; Especially suitable for materials with high viscosity, low fineness, and high volatility (closed grinding).
Working principle of horizontal Sand Mill
The horizontal Sander is a fully enclosed wet grinding and dispersing machine with continuous operation, which is transported by pump
Liquid raw materials enter the closed grinding cylinder of the horizontal Sander, and then the host drives the meson grinding beads to transport at high speed. Rotation causes the raw materials to undergo high-speed rotation and impact under pressure in the narrow grinding bead gap, resulting in mixing, emulsification.
The grinding functions of dispersion, rubbing, rolling, etc. quickly grind and disperse the material particles into aggregates, thereby
It can meet the requirements of raw material fineness and narrow particle size distribution range. Grind and then rotate at high speed
The separation gap of hard tungsten steel is output outside the grinding cylinder, while the grinding beads are still left inside the cylinder. Grinding for one cycle Homework.
The following introduction of horizontal Sand Mill
1. The horizontal Sander consists of the body, transmission system, grinding shaft, grinding cylinder, feeding system and electric control system.
2. Wet grinding method makes the grinding speed of the medium faster and more evenly distributed.
3. The grinding operation of horizontal Sander is carried out at high speed in a fully enclosed and pressurized grinding cylinder.
Turning to grinding, there is no problem of solvent volatilization polluting the air, ensuring workshop hygiene and operation.
The physical and mental health of personnel. Because there is no solvent volatilization, energy is saved and production costs are reduced.
4. The bottom of the grinding cylinder is equipped with a sliding track for easy replacement of grinding beads and disassembly during maintenance and repair, as long as it is disassembled.
Fix the screw to open the grinding cylinder and allow the grinding beads to flow out.
5. A mechanical shaft seal is installed between the transmission structure and the grinding structure of the horizontal Sander, and solvent is used.
Type B liquid circulating lubrication mechanical shaft seal, separating grinding materials from transmission structure, circulating lubrication mechanical shaft.
The sealed solvent is stored in a storage bucket and transported to a cooling water circulation to cool and lubricate the solvent.
6. The pumps for raw material transportation of horizontal Sander are divided into gear pump and pneumatic double diaphragm pump for users to distinguish according to the physical properties and characteristics of raw materials to be ground.
