Divided from the structure of the two colloid mills: The installation size of the new intelligent colloid mill is different in height, horizontal and vertical. Axial positioning must be considered horizontally to prevent the motor shaft from moving in the axial direction. It is better to use a motor front end cover bearing because the axial thermal expansion of the motor rotor and shaft is designed so that the front bearing of the motor is oriented toward the rear bearing of the motor. Move to reduce the impact on the head gap. Because the vertical colloid mill is installed vertically by the motor, the shaft of the motor will not move axially due to the weight of the rotor of the motor. Therefore, axial positioning may not be considered. Horizontal colloid mill due to horizontal installation, such as the discharge port should be placed under the discharge port discharge valve so that long-term shutdown of the material within the colloid mill put away, anti-pollution disc design to consider the gravity return material gravity, vertical type do not. The efficiency of the two colloid mills is close to a high score. In short, the horizontal type of new intelligent colloid mill is also called pipeline colloid mill-abrasive pump, grinding type grinding pump is the front-end technology products, first at home and abroad.
