Plastics Powder Processing
Improved Self-clearing of Poor Flow Powders in Large Silos
|
Achieving mass flow discharge, and preventing bridging and formation of rat holes, in large silos can be problematic when an existing silo is used to store new materials. |
Animal Feed Production
Process Control Raises Productivity and Profits
|
Every animal feed producer knows, the closer moisture content comes to the permitted threshold the more profitable production becomes. Maximum exploitation of this potential can be achieved by using on-line process analysers. Real time permanent process control assures that each batch precisely reaches the required moisture and protein value. |
Quality Control
How to Collect a Representative Sample? - A Brief Introduction to the Sampling World
|
If you have to analyze 200 grams of product, but you have a ship with 50.000 tons of product ... How shall you proceed? |
Fire & Explosion Protection
Understanding Dust Explosions - The Role of Powder Science and Technology
|
For any given dust type the ease with which dust clouds ignite and the rates with which they burn, vary considerably with factors well known in powder science and technology. This article discusses the influence of these factors on ignition sensitivity and explosion violence and describes the concept of inherently safer process design as well as the design of mitigatory measures |

Open Pit Mining
Lausitz Production Data Network - A Network in Industrial Use
|
After a virus attack in 2003 Vattenfall Europe Mining searched for a Production Data Network that would ensure production security and allow integration and harmonization of existing solutions and interfaces. Together with PC-Soft GmbH a system was developed that meets these expectations. |
Flow Properties
Preparing the Removal of Low-level Radioactive Waste
|
Predicting the Flow Behavior of Solids After Fifty Years Storage Using Sampling and Flowability Studies - Winning the cold war was a national priority when the Atomic Energy Commission, predecessor to the Department of Energy (DOE), broke ground for uranium feed materials production at Fernald in Hamilton, Ohio in 1951. Read here about the cleanup of the solid’s part of the mess. |
Belt Sampling
Automated Consignment Sampling
|
Automated sampling is vital for companies mining, handling or using coal. The following article is a case study where consignment sampling has been implemented at a UK coal fired power station. |
Drying
Optimized Spray Dryer Temperature - by Applying an Adapted Smouldering Test
|
Instead of the usual smouldering test for determining the maximum drying air temperature, the results of which are not always conclusive, a new variant of this test can be used to define the maximum drying temperature of spray dryers more exactly. |
Composite Powders
Aluminium Matrix Composites - Effects of Powder Compositing on SiC Distribution
|
Aluminium matrix composites are materials with very promising characteristics. Various additive materials and the different ways to combine additives and base material were tested to improve the overall characteristics. |
Size Reduction
Ball-milling of Composite Powder - Cathode Production for Alkaline Batteries
|
Improving the capacity and longevity of alkaline batteries is since long an aim of intensive research. An approach for the production of the Kathode is presented here. |
