Ceramic grinding product series

Product Introduction

Structural composition:

• Grinding media:

usually particles in the shape of balls, columns, sheets, etc. made of ceramic materials. Common ceramic materials include alumina, zirconium oxide, silicon carbide, etc. These materials have the characteristics of high hardness, high strength, wear resistance, corrosion resistance, etc., and can effectively grind various materials.

• Grinding container:

a container for holding grinding media and ground materials, which can be a can, barrel, ball mill cylinder, etc. The material of the grinding container is usually selected according to the properties of the ground material and the grinding requirements. Common ones include stainless steel, ceramic, polyurethane, etc.

• Drive device:

provides power for the grinding process. Usually, the motor drives the grinding container or agitator to rotate through a transmission device such as a belt or gear, so that the grinding media moves in the container, and the ground material is impacted, rubbed and sheared to achieve the grinding effect.

• Working principle:

put the ground material and ceramic grinding media into the grinding container, and rotate the grinding container or agitator through the driving device to drive the ceramic grinding media to move in the container. During the movement, the ceramic grinding media will collide, rub and shear with the material being ground, so that the particles of the material being ground gradually become smaller and reach the required fineness and particle size distribution. During the grinding process, the shape, size, hardness, density and other parameters of the grinding media and the shape, rotation speed, filling rate and other factors of the grinding container will affect the grinding effect.

Advantages and characteristics

• High hardness and wear resistance:

Ceramic materials have very high hardness, which is generally much higher than the hardness of the material being ground, so they can effectively grind various materials with very little wear. This makes ceramic grinding products have a long service life and reduces the frequency and cost of replacing grinding media.

For example, when grinding materials with higher hardness such as silicon carbide and sapphire, ceramic grinding media can maintain good grinding effects, while ordinary grinding media such as steel balls will wear quickly, affecting grinding efficiency and product quality.

The hardness of alumina ceramic grinding balls can reach Mohs hardness level 9, and the hardness of zirconia ceramic grinding balls is higher, which can meet the grinding needs of various high hardness materials.

• Corrosion resistance and pollution-free:

Ceramic materials have good corrosion resistance and can work stably in various corrosive media such as acids, alkalis, and salts. They will not react chemically with the materials being ground, thereby ensuring the purity and quality of the materials being ground. At the same time, ceramic grinding products will not produce metal pollution during use, and are particularly suitable for grinding electronic materials, pharmaceutical materials, food materials, etc. with high purity requirements.

For example, when grinding electronic ceramic slurry, the use of ceramic grinding media can avoid the introduction of metal impurities and improve the performance and quality of the slurry.

In the pharmaceutical and food industries, ceramic grinding products can meet strict hygiene standards and quality requirements to ensure the safety and reliability of the products.

• Good thermal stability:

Ceramic materials have good thermal stability and can work stably in high temperature environments without deformation or cracking due to temperature changes. This allows ceramic grinding products to be ground under high temperature conditions and is suitable for grinding some materials that require high temperature treatment.

For example, when grinding certain high-temperature ceramic materials or materials after high-temperature reactions, ceramic grinding media can maintain good performance, while ordinary grinding media may fail due to high temperatures.

Silicon carbide ceramics have high thermal conductivity and thermal stability, can quickly dissipate heat at high temperatures, and maintain a stable grinding effect.

• Precise particle size control:

The shape and size of ceramic grinding media can be customized according to different grinding requirements, and precise particle size control can be achieved. By selecting appropriate grinding media and adjusting grinding process parameters, the required particle size distribution and fineness can be obtained to meet the requirements of product particle size in different industries.

For example, in industries such as electronic materials, coatings, and inks, the particle size requirements for products are very strict, and ceramic grinding products can meet the high-precision grinding needs of these industries.

By controlling parameters such as grinding time, rotation speed, and filling rate, the particle size of the ground material can be adjusted to achieve particle size control from micron to nanometer level.

• Efficient grinding effect:

The density of ceramic grinding media is moderate, and sufficient impact force and friction can be generated during the grinding process to quickly break and refine the particles of the ground material. At the same time, the surface of ceramic grinding media is smooth, not easy to adhere to materials, and can maintain good fluidity and grinding efficiency.

For example, compared with traditional grinding media such as steel balls, ceramic grinding products can achieve the same grinding effect in a shorter time, improving production efficiency.

In the grinding of some high-viscosity materials, the good fluidity of ceramic grinding media can effectively avoid material agglomeration and blockage, and improve grinding efficiency.
