There is a deeper layer of coffee grounds in a cone shaped filter than there is in a flat shaped filter. This means that the water has more contact time with the grounds which means cone filters make a slightly stronger cup of coffee. Vacuum pots and siphon brewers also work well with this grind type. Medium Ground. Medium-Coarse coffee looks like regular sand— not the powdery Caribbean kind ...

SELECTING THE CORRECT Grinding Media SHAPE. Generally, the ball shape is preferred for converting large size feed materials into finely ground products. The size depends primarily on the material to be ground and on the work to be done. Natural-Shaped Media With its sliding, mortar-and-pestle action, the Natural Shape is best when there is little requirement for primary size reduction. .
