Working Party on Mechanics of Particulate Solids

Welcome to the web page of the EFCE Working Party on the Mechanics of Particulate Solids. The main aim of the working party is the promotion of science, education and technology transfer in the subject area of bulk solids handling and transportation in the EFCE member countries. The working party promotes interaction between industry and academia to enable improvement of bulk solids handling science and technology.

The working party was founded in 1969. Since then it has run numerous technical projects mainly concerning the characterisation of bulk solids for flow. Its most prominent outcome being the SSTT (Standard Shear Testing Technique for Particulate Solids Using the Jenike Shear Cell). This document has become the basis of several standards, most notably those by ASTM on Jenike and Ring Shear Testing.

For most of its time the Working Party on the Mechanics of Particulate Solids has been led by Dr. Jan Novosad of Czechoslovakia (later Czech Republic). In the period 2001 - 2007 it was led by Dr. Hermann Feise, an industrial delegate from Germany, and from 2008 to 2013 by Prof. Massimo Poletto from Italy. Since 1 January 2014, the Working Party is headed by  Prof. Alvaro Ramirez- Gomez, Madrid, Spain. The working party currently has 47 members from 15 European countries.



Events related to Mechanics of Particulate Solids:



9th World Congress on Particle Technology


The World Congress on Particle Technology (WCPT) is the world’s major scientific congress for particle and bulk solids technology. It is an international forum for research, technological development and innovation in new technologies. The results presented and discussed in every edition of WCPT have come from different research fields (chemical, pharmaceutical, food production, mining, agricultural, energy…) and have been beneficial for many industrial applications. Held every 4 years since its inception in 1990, is intended to stimulate discussions on the forefront of research in particle science and technology. The next World Congress on Particle Technology (WCPT9) will be celebrated in September 2022, in Madrid.



International Symposium Reliable Flow of Particulate Solids V

Skien, Norway, 13-15 June 2017 (EFCE Event No. 734)


International Conference on Processing, Handling and
Characterization of Particulate Materials

held in the frame of the
World Congress of Chemical Engineering 2017 (WCCE10)

1 - 5 October 2017, Barcelona, Spain

This new conference on particulate materials (PARMAT2017) is organized by eight Working Parties of the European Federation of Chemical Engineering (EFCE) in the frame of the WCCE10-ECCE11-ECAB4. This initiative started in ECCE10 aiming to be a meeting point for academia and industry to share the latest scientific progresses and technological advances in fields were particulate materials are involved. More specifically, PARMAT2017 is devoted to all the aspects related to the chemical and mechanical processing, handling and characterization of particulate materials in industry, including hazards and risks that are usually presented during these operations. This International Conference will provide a unique opportunity to integrate academic/scientific research and industry issues and requirements from researchers and industrialists around the world”.
