Effect of calcium powder residue content on the processing and performance of PVC products

Calcium carbonate ball milling and classification + powder coating and modification production line

Calcium powder residue content greatly affects PVC (polyvinyl chloride) products. It impacts their mechanical properties and overall quality. Calcium carbonate is a common PVC filler. It is key to their properties. Impact on the appearance of PVC products Excessive calcium powder residue may cause the gloss of PVC products to decrease, and the color to […]

Surface modification method of non-metallic mineral powder

Three-roller Coating Machine

Surface modification is key to improving non-metallic mineral powders. It enhances their properties and applications. Non-metallic minerals, like talc, kaolin, and calcium carbonate, are used in many industries. These include plastics, paints, ceramics, and pharmaceuticals. However, their properties often need improvement to meet application demands. Surface modification techniques can greatly change the properties of these […]

How Does the Classification Process Work in a Jet Milling

Alumina Ceramic Classifying Wheel

A jet milling’s classification process is vital for reducing and separating particle sizes. This is crucial in industries like pharmaceuticals, food processing, and materials science. This process uses high-velocity air jets for fine grinding. It also classifies particles by size and density. Knowing how this process works can improve efficiency, product quality, and energy use. […]

Particle size? Mesh size? How to convert mesh and micron?

Granularity Reporting

[In general, mesh number × aperture (micrometers) ≈ 15000.] For example, a 100-mesh screen has a 150-micron aperture. A 200-mesh screen has a 75-micron aperture. A 300-mesh screen has a 48-micron aperture. A 500-mesh screen has a 30-micron aperture. Below is a conversion between common mesh numbers and particle sizes. Mesh Micron (μm) Mesh Micron […]

How does the jet pulverizer ensure high purity in the grinding process

Ceramic Classifying Wheel

In the world of particle size reduction, keeping the product pure is key. This is especially true in industries where the final product’s quality matters a lot. The jet pulverizer, a cutting-edge air-based grinding tech, is crucial for keeping the grinding process pure. It uses compressed air to efficiently cut down particle sizes while keeping […]

What problems are often encountered in dry grinding of calcium carbonate?

Heavy calcium carbonate

Dry grinding of calcium carbonate makes heavy calcium carbonate. It is a common process. It is widely used. It has a low equipment cost, a simple process, and high output. Its technology is mature and it consumes little energy. However, some problems may arise in production, including but not limited to: Granularity Limitation in Dry […]

How does the jet mill maintain a low grinding temperature?

Jet mills for processing heat-sensitive materials

Jet mills are specialized devices for grinding materials. They are used where fine particle sizes are needed. A key benefit of jet mills is their ability to keep a low grinding temperature during milling. This is crucial for materials that can be sensitive to heat, such as pharmaceuticals and certain chemicals. Mechanisms for Low Grinding […]

Brief Analysis of the Importance of Alumina in  Practical Applications

Alumina

Alumina is a new variety. New varieties are often unfamiliar to most people, but they are also opportunities. Alumina has a very important property: although it seems sufficient, once it is in short supply, aluminum plants will suffer huge losses, or production accident or explosion, even long-term closure. As we all know, aluminum smelters, glass factories, and steel mills are the three major […]
