Product Overview

The stainless steel appearance vertical nano sand mill is an advanced wet grinding equipment with a vertical design and all contact parts made of high-quality stainless steel. It integrates precise mechanical design, efficient energy input and intelligent control systems, and is specifically designed for grinding materials to sub-micron or even nanometer levels (typically up to D50 < 100 nm). Its classic stainless steel appearance not only highlights the characteristics of being sturdy, durable, clean and hygienic, but also represents the dual pursuit of quality and aesthetics in modern industrial manufacturing. It is an ideal choice for high-end industries such as coatings, inks, dyes, electronic pastes, cosmetics, lithium battery materials, and pharmaceutical nano-preparations to achieve product upgrades.

Core design features

Vertical structure & all-stainless steel contact parts

High stability: The vertical design makes the main shaft run more smoothly, avoiding the possible problems of uneven wear and vibration that may exist in horizontal machines, and extending the service life of bearings and mechanical seals.

No dead corners design: Combined with specially structured grinding discs or pins, it forms an efficient axial circulation, ensuring thorough material exchange, extremely high grinding efficiency, and a more concentrated particle size distribution.

Clean and corrosion-resistant: All components in contact with materials (cavities, shafts, grinding discs, separators, etc.) are made of 316L or higher grade stainless steel to ensure no pollution, corrosion resistance, easy cleaning, and meet GMP and high cleanliness production requirements.

Aesthetically pleasing and durable: The exterior is entirely made of stainless steel with a brushed or mirror-finished finish, presenting a simple and elegant appearance with strong anti-fouling ability, making it suitable for modern workshop environments.

Nanoscale grinding system

High energy density: Utilizing high-performance motors and optimally designed grinding rotors, it can generate extremely high linear speed and shear force, ensuring that energy is effectively transferred to every material particle.

Ultrafine separation system: Equipped with a standard dynamic gap separator or high-performance centrifugal separation screen, the gap can be precisely adjusted (as small as 0.1mm or less). While ensuring a large flow rate, it can retain 100% of the grinding media, ensuring that the discharged products are free from medium contamination and achieving true nanomet-level discharge.

Precise temperature control and sealing

Integrated cooling jacket: Both the grinding chamber and the discharge port are equipped with precise cooling systems, which can precisely control the grinding temperature and prevent the material from denaturating due to high temperatures. It is especially suitable for heat-sensitive materials.

Double-end face mechanical seal: It adopts a high-quality double-end face mechanical seal system, which can be selected for solvent cooling or lubrication, completely eliminating leakage, ensuring long-term continuous safe production, and supporting pressure operation.

Intelligent control and human-computer interaction

PLC touch screen control system: Integrated control panel, real-time monitoring and adjustment of key parameters such as spindle speed, feed pump speed, temperature, pressure, and operation time.

Data recording and formula management: It can store multiple sets of process formulas, enabling one-click invocation and ensuring consistency between product batches.

Safety interlock and alarm: It is equipped with multiple safety protection functions such as motor overload, abnormal sealing pressure, temperature limit, and power-off when the door is opened.

Core advantage

Small particle size limit: Professional nanoscale grinding and separation technology makes it easy to achieve product nanoscale.

More uniform distribution: Vertical circulation and efficient dispersion ensure a narrow particle size distribution and enhance product quality.

Pollution-free operation: The all-stainless steel structure and reliable separation system ensure the purity of the final product.

High efficiency and energy saving: Optimized fluid dynamics design ensures high energy utilization and low energy consumption per unit output.

Stable and reliable: Heavy-duty mechanical structure and high-quality components support 24-hour continuous industrial production.

Easy to clean and maintain: The quick-opening design allows all contact parts to be disassembled quickly, significantly reducing the time for material change, cleaning and maintenance.

Typical application fields

High-end pigments and dyes: nano color pastes, digital printing inks, automotive coatings.

New energy materials: Lithium battery positive and negative electrode slurries (LFP, NMC, silicon-carbon negative electrodes), graphene conductive slurries.

Electronic chemicals: MLCC electronic paste, photovoltaic conductive silver paste, PCB ink.

Biomedicine: Nano-liposomes, drug nano-suspensions, microsphere preparations.

High-end cosmetics: sunscreen (nano TiO2/ZnO), essence, makeup raw materials.

Fine ceramics: Structural ceramic precursor slurries such as zirconia and alumina.
