        Main Reasons for Powder Dropping of Pill Core

        來源:www.taietel.com 發表時間:2019-06-26

        Pellet core is the necessary master batch for preparing skeleton pellets. It requires a round surface, uniform particle size, solid, heavy and low fragility, good solubility or wettability. What are the reasons for the powder loss of the pellet core?
        (1) The main reasons for powder dropping are: (1) The fragility of sugar pills is not good. It is suggested that another manufacturer try it. (2) Inappropriate air volume: the smaller the particle size, the more intense the pellet movement and the greater the friction with the same air volume.
        (2) Adhesion: Adhesion occurs when the particle size of pellets decreases, which indicates that the combination mode of liquid and pellets changes from complete coating to granulation to a certain extent. There are many mechanisms, the most effective way is to slow down the spray rate. In addition, attention should be paid to the electrostatic problems caused by the decrease of the particle size of pellets. When the static electricity is large, the electrostatic adsorption between pellets is strong, and it is difficult to separate effectively. When the pellets are coated, it is easy to form a solid bridge at the pellet junction, leading to adhesion.
