The particle size distribution of cathode material is one of the most important variables in lithium-ion battery performance. Too wide a distribution and your electrode coating is uneven, ion diffusion is inconsistent, and capacity varies between cells. Too many oversized particles – even a handful of what engineers call killer particles – and you risk […]

1. Understanding the Fundamentals: What is an Air Classifier? Definition and Core Working Principle An air classifier is a sophisticated powder processing device that utilizes a controlled airflow field to separate particles. This separation process is based on the physical properties of particles such as size, density, and shape. By adjusting the airflow velocity and

Petroleum coke is a product obtained from the distillation of crude oil, where light and heavy oils are separated, followed by the thermal cracking of the heavy oil. It has an irregular shape, with carbon being its primary elemental component. As a fuel, petroleum coke can replace heavy oil, representing an excellent pathway for new

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,
