Attrition
Attrition refers to the gradual wear and reduction of particle size due to mechanical forces like friction, impact, or shear. This phenomenon plays a critical role in industries such as pharmaceuticals, mining, and food processing, where particle integrity affects product quality and performance.
On this page, explore the causes, effects, and solutions for managing attrition, ensuring optimal material performance and process efficiency.

Pneumatic Conveying Attrition: Transfer Quietly Changes Powder
Pneumatic conveying attrition can change a powder even when the transfer looks successful. A line may run without blockage, and the material may still arrive with a broader PSD, more fines, and altered handling behavior. Therefore, if downstream dustiness, feeding, or blend performance shifts after transfer, the conveying line itself should be treated [...]
Selecting the Right Powder Mixer for your blend
There is no one-size-fits-all powder mixer—the right choice depends entirely on your powder’s flowability, sensitivity, particle size, and process needs. Whether you need gentle handling for fragile particles or intense shear for cohesive blends, matching the mixer to your material ensures better blend quality, efficiency, and product consistency. Selecting the wrong mixer can [...]
Powder processing and their diverse phenomena
The term "atom" originated in ancient Greece around 400 B.C., stemming from atomos, which means "indivisible" or "uncuttable." While the term persists, science now shows that atoms can split through fission reactions. Yet, atoms remain the foundational particles of matter, each uniquely defining an element on the periodic table. Atoms begin their journey [...]
Milk Powder and the various stages of processing
In the 1920s and 30s, Sweden faced a dairy surplus. To address this, a marketing strategy promoted fresh pasteurized milk as a healthy daily staple. This campaign spurred the dairy industry's growth but highlighted milk’s perishability. Milk serves as an excellent medium for microorganism growth, making it highly perishable. To ensure safety, milk requires [...]
Wear of the pneumatic pipeline walls:  contaminating the conveyed material
In Pneumatic Conveying Systems, particle velocity and bend geometry drive erosion and contamination. Minimize bends, tune velocity, and verify with regular sampling to protect product quality. Table of contents Pneumatic conveying systems (PCS) are essential in industries that handle bulk solids, moving materials from fine [...]
