sieve trials provided some promising findings, suggesting that the Russell Compact Sieve could be used successfully within lunar gravity. The video footage also showed that the product flow within the sieve was very similar when compared to the same sieve trials carried out at the airbase. “The results were encouraging and signify an early indication that one-day sieving on the moon could be possible. It is hoped that further experiments will be undertaken in the following years.” Wong concludes, “It was good to establish connections between NASA, the University of Wisconsin – Madison and Russell Finex. Our relationship with Russell Finex will be something we can look on in the future.” Following the success of this research NASA purchased a double deck Russell Compact Sieve (see figure 2). With this machine they aim to continue the research that the University of Wisconsin – Madison started. One of the first major developments in the project will be to carry out


the lunar regolith simulant at the desired time as well as being able to control the feed-rate. A video camera was also installed inside the sieve to record product flow characteristics. With the first phase of the trials complete, the results of the


experiments using lunar soil that has been extracted from the moon rather than a lunar regolith simulant. For more information contact Russell Finex on tel: 0208 818 2058 or visit: www.russellfinex.com
