What is an Air Classifier? ””’An air classifier is a mechanical device used to separate particles based on their size, shape, and density through airflow. It works by directing air currents to sort materials, allowing finer particles to be separated from coarser ones efficiently. IWidely used in industries such as mining, pharmaceuticals, food processing, and […]

At Epic Powder Machinery, we believe that great partnerships transcend borders. Our recent collaboration with an Australian industrial client stands as a testament to what happens when Chinese engineering meets demanding Australian quality standards. This calcium carbonate processing project wasn’t just about shipping equipment across oceans, it was about delivering complete solutions and lasting partnerships.

What Is Wollastonite? Key Properties And Market Overview Wollastonite is a natural mineral with the chemical formula CaSiO₃, known for its unique acicular (needle-like) crystal structure. This fibrous shape delivers distinct physical properties ideal for various industrial applications. Wollastonite powder typically needs to meet strict fineness standards, often aiming for a D97 of 5–15 μm.

Introduction to Air Classifiers Air classifiers are essential equipment in powder processing industries, utilizing airflow and centrifugal forces to separate particles based on size, shape, and density. Unlike traditional screening methods, air classifiers offer a dry, dynamic separation process that achieves precise particle size distribution (PSD) without the need for water or mechanical sieves. This

In the rapidly growing field of metal additive manufacturing (3D printing), metal injection molding (MIM), and powder metallurgy, stainless steel powder remains one of the most widely used materials. However, achieving the optimal particle size distribution is critical for final part quality, flowability, packing density, and printability. Many stainless steel powder producers and users face

In high-end coatings, plastics, and cosmetics, sericite is a key functional filler that improves gloss, smoothness, and mechanical performance. Yet turning standard 325-mesh sericite into ultra-fine powder with D97 ≤ 10μm is technically challenging for most production lines. Producers must solve one core problem: how to balance high throughput (around 1300 kg/h) with a precise

The Turbo Air Classifier, also known as a Turbo Classifier or Dynamic Air Classifier, is a highly efficient device widely used for the dry classification of ultrafine powders. It is particularly suitable for powder industries with stringent requirements on particle size distribution, high product purity, and large processing capacities, such as battery materials, electronic ceramics,

This article discovers the purpose, principles, and types of ultrafine powder classification equipment. Learn the differences between dry and wet methods, common classifiers like centrifugal and jet types, and their applications in modern industry. Purpose and Significance of Classification Mechanically produced ultrafine powders often cannot achieve the desired particle size in a single grinding pass,

The Hidden Variable in Battery Performance Why do two batteries with identical chemistry sometimes deliver vastly different lifespans and power outputs? The answer often lies not in the material itself, but in its physical architecture. For lithium-ion cathode powders, inconsistent particle size is the performance killer. It leads to uneven current distribution, accelerated degradation, and
