Plant Grinding and Dispensing System Labman

The grinding module shakes the tube causing the ball bearings to pulverize the contained plant sample. After grinding, the system then de-clogs and pierces the input tube and places it into the feeding station. An output tube is placed directly below the input tube; the feeding station vibrates the input tube to disrupt the ground sample, thus
