www.PowderProcess.net - Online handbook for Engineers working with powders and bulk solids


Your site of reference for Powder and Solids processing

Discover below the content of the free online handbook

What is www.PowderProcess.net ?

www.PowderProcess.net is a free online handbook giving explanations, design methods and operational tips on the most common unit operations and equipment found in Industries processing powders.

It gives materials for Engineers who, around the world, have to design, operate or troubleshoot a powder handling process.

Would you be a confirmed Engineer, a new graduate looking for information on the process he has 1st to work on, or a student, please access below articles on unit operations and equipment that, we hope, will be useful for you. www.PowderProcess.net also hosts Process Engineer's Tools, a new online ressource for Process Engineers, not limited to Powder Processing - This subsite is still in development.
