In a series of articles on LinkedIn, Tim Freeman, Managing Director of Freeman Technology, draws on over 20 years of experience in the industry and has looked at variables that can impact powder behaviour.
In recent posts, he started by examining the effect of various particle properties, including size and shape, and in his latest post he now turns to an external variable - humidity. Moisture can significantly influence powder behaviour, especially flow properties, and quantifying its effect is essential to develop effective control strategies for a specific application. There can be significant cost involved in removing water from the atmosphere in a processing environment, or indeed from within the powder itself. These costs must be balanced with the economic benefit of maintaining acceptable processing performance. The challenge is to understand a powder’s appetite for moisture uptake and, more importantly, how moisture will affect its characteristics and performance.
