Automatic particle size analyzer using stacked sieves |
| abstract |
The size range of particles separated on a stack of sieves (16a-16f) of different mesh sizes is measured automatically. The stack is clamped together and shaken as a unit to separate the respective fractions, following which the sieves are sequentially separated from the stack and inverted one at a time to dump the fraction retained on each, onto a scale (102). Each fraction is weighed separately and their relative proportions can be calculated automatically. In a preferred embodiment the sieves are individually cantilevered from a vertical conveyor (28). The sieves are inverted one by one to dump their contents by advancing them around a horizontal roll (32) at a lower end of the conveyor. |
