Sixteen grid bar arrangements were tested to evaluate the potential benefits of adjustable grids for both the extracting saw and the reclaiming saw in a bur and stick extractor. Four grid spacing arrangements for the primary extraction saw were evaluated in combination with similar spacing arrangements for the grids around the reclaimer saw cylinder. Increases in grid spacing tended to increase both cleaning efficiency and lint wastage. Several of the grid spacing combinations produced about the same cleaning efficiency, but widely different lint wastage values. Results indicated that care should be taken in selecting a grid spacing arrangement if one wishes to maximize efficiency at a tolerable lint wastage level. Large variations were also encountered in cleaning performance and lint wastage among test cottons. These large differences in stick extractor performance illustrate the difficulty of selecting a single grid spacing arrangement that will produce satisfactory results for a wide range of stripper harvested cottons. One potential solution to this problem would be to develop the means for quickly adjusting the grids bars used in these types of machines, especially those grids used around the primary sling-off saw cylinder.
