High-Shear Mixing Apparatus

A high shear mixing device, comprising:

• a first screw kneader and a second screw kneader;
• a first rotation driving mechanism for rotating the first screw kneader and a second rotation driving mechanism for rotating the second screw kneader;
• a revolution driving mechanism in which the first rotation driving mechanism and the second rotation driving mechanism are rotatably installed;
• a driving mechanism body in which the revolution driving mechanism is installed;
• and
• a mixing tank,
• wherein:
• each of the first screw kneader and the second screw kneader comprises a shaft and three blades, the shaft including one end connected to the rotation driving mechanism and each of the three blades having one end fixed to the shaft and having a body spirally curved along a longitudinal direction of the shaft,
• each of the first and the second screw kneaders is configured to rotates in an opposite directions to the other screw kneader such that the three blades of each of the first and the second screw kneaders overlap each other,
• one blade of the three blades in each of the first screw kneader and the second screw kneader is an open-type blade having through holes formed in a center of the respective blade except for an outer periphery of a rotation direction surface of the blade, and the other two blades of the three blades are both closed-type blades having a closed rotation direction surface without a through hole,
• the open-type blade in the first screw kneader is positioned between the two closed-type blades in the second screw kneader, and
• the open-type blade in the second screw kneader is positioned between the two closed-type blades in the first screw kneader.
