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.

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 of the conveyed material
Pneumatic conveying systems (PCS) are essential in industries that handle bulk solids, moving materials from fine powders to mm-sized granules. By suspending particles in an air stream, PCS can transport materials horizontally, vertically, or at an incline over distances ranging from a few meters to hundreds. With the system fully enclosed, there is [...]
Key Considerations for Building or Upgrading a Facility
In this article, we will discuss the relevant aspects when working on a Solids handling facility design. Designing or upgrading a facility involves many factors. Local conditions play a critical role in selecting the right approach for solids handling. Site evaluation should consider aspects like land availability, land use, proximity to homes, and [...]
Introduction to Dustiness
Airborne dust is a common byproduct of both natural and human activities. Natural sources include volcanic eruptions, wildfires, and even ocean emissions. On the other hand, industrial processes, especially those dealing with powders, granular materials, or fibers, contribute significantly to airborne dust. During processes like conveying and transport, particles such as asbestos, cement, [...]
