There is air in the pellets during compression. Relatively fast during compression. Punch with a punch. The gap in view is relatively small. After compression, the air is not removed from the particles, but is trapped in the flakes. When there is no pressure, the air expands, which causes splitting. According to the above situation, we should first make the fine powder in the granules into a pre-pressing device to let the air escape. However, many cases cannot be explained. Splitting occurs when the pressure is relatively high. Tablet process
