Production type sand mill

Product Introduction

The mass-production nano sand mill is a high-efficiency grinding equipment specially designed for industrial mass production. It is mainly used to disperse solid particles to the nanometer level (usually up to 200nm or less). It is widely used in high-precision fields such as lithium battery materials, coatings, inks, and medicine. Its core design focuses on high productivity, continuous operation stability and low energy consumption. The structure uses a large-capacity grinding chamber, high-strength wear-resistant materials (such as tungsten carbide, zirconia) and an intelligent control system to support long-term continuous operation. Through dynamic separation technology and optimized grinding media distribution, the equipment can achieve uniform nano-scale particle crushing and dispersion to meet industrial-level production needs.

Mass-produced nano sand mills mainly serve the following industries:

1. New energy field : Nano-grinding of lithium battery positive and negative materials (such as lithium iron phosphate, ternary materials) to improve battery energy density and cycle life.

2. Chemicals and Coatings : Dispersion of high-precision color paste, ceramic ink, nanopigment, and preparation of special coatings (such as magnetic coatings, heat-insulating coatings).

3. electronic materials : Ultra-fine processing of MLCC (multilayer ceramic capacitor) slurry and electronic ceramic powder.

4. Pharmaceuticals and Cosmetics : Homogeneous dispersion of pharmaceutical nano-preparations and functional cosmetic raw materials.

5. Special materials : Dispersion of carbon nanotubes and graphene slurries and synthesis of functional nanomaterials.

Technical parameters

• Choose according to production capacity needs :

  • Small-scale mass production (500-2000L/h): Choose medium-sized equipment with a cylinder volume of 15-60L and a main motor power of 22-45kW.

  • Large-scale continuous production (>5000L/h): Priority is given to large-scale equipment with a cylinder volume of more than 100L, equipped with high-power motors (≥90kW) and automatic feeding systems.

• Adapt according to material characteristics :

  • High viscosity materials : Choose a horizontal sand mill or a large-flow pumping system to ensure material fluidity.

  • Pollution prevention needs : Use ceramic or polyurethane grinding chamber and separator to avoid metal ion contamination.

• Additional functionality considerations :

  • Temperature control sensitive : Optional dual-circulation cooling system or heating jacket to accurately control material temperature.

  • Automation integration : Priority is given to models that support intelligent control systems (such as PLC + touch screen) to facilitate linkage with other equipment in the production line.

• Energy consumption and maintenance costs :

  • Compare the unit energy consumption of the equipment (kW·h/ton) and the replacement frequency of wearing parts, and choose a model with long maintenance cycle and low energy consumption.

Working Principle

1. The grinding media is accelerated by the rotation of the rotor to the inner wall of the grinding barrel. The grinding media moving toward the barrel wall will collide with the grinding media or grinding materials close to the inner wall of the grinding barrel. The resulting collision can be used to disperse and crush the materials.
2. Under the action of centrifugal force, the grinding material is close to the inner wall of the grinding barrel and receives the pressure and shearing force of the adjacent medium to disperse and break.
3. Due to the different distances between the grinding media and the axis, the obtained speeds are different, resulting in speed differences. Collisions will occur during the movement to break the materials.
4. In the early stage of grinding, the particle size is large, and impact crushing plays the main role. As the grinding time increases, the ground material gradually becomes finer, and at this time, friction, shearing and crushing mainly occur in the grinding barrel.

Product Features

• High productivity and stability :

  • The processing capacity can reach more than 2000L/h, supporting continuous or cyclic production mode to meet large-scale needs.

  • Use high-strength wear-resistant materials (such as carbide, ceramics) and double-end mechanical seals to extend equipment life and reduce downtime maintenance.

• Intelligent control :

  • Integrated PLC control system and touch screen operation interface support parameter preset, real-time monitoring and data recording to ensure process repeatability.

• High performance design :

  • Dynamic separation technology (such as gap separator) enables rapid separation of grinding media and materials to avoid blockage and leakage.

  • The forced cooling system (water cooling or air cooling) controls the grinding temperature to prevent heat-sensitive degradation of materials.

• Wide adaptability :

  • It can handle materials with a viscosity range of 20mPa·s to 20000mPa·s, and supports a variety of grinding media (0.05-2.0mm zirconia beads, silicon carbide beads).

  • The modular design allows the grinding chamber material (such as polyurethane, ceramic) to be replaced to avoid cross-contamination of materials sensitive to metal contamination.
