　　Handling problems when installing hoop for wet granulator

　　The wet granulator is developed with new technology, which can realize the rapid replacement of different capacity pots. It is a process verification equipment commonly used in laboratories in the pharmaceutical, food, dairy, chemical and other industries. It has various functions such as mixing and granulating.

　　Wet granulator adopts mixing paddles with different structural forms, which can use tangential and zigzag paddles. The slurrying system uses peristaltic pumps and spray guns to add adhesive. The control system uses stirring paddle motors and granulating knife motors with variable frequency governor control. ; The current torque of the agitator reducer is displayed on the touch screen. Pneumatic automatic discharge can be used to realize rapid replacement of the pot body.

　　Analysis of Broken Pin of Wet Granulator:

　　1. Reason: When the hoop of the wet granulator is installed, one end of the screw is tightened at a time, which causes the positioning pin to be broken.

　　2. Consequences: There are gaps between the three-piece hoop of the wet granulator. After the granulator is running, the three gaps are not in contact with the hoop and rub, thus forming three high points. When the hoop positioning pin is replaced, the hoop will be mounted on three high points when the hoop is replaced again, so that the surface contact of the hoop becomes point contact. After the granulator starts working, the hoop will be accelerated. The wear of the hoop will further accelerate the wear of the transmission wheel, which greatly reduces the service life of the hoop and the transmission wheel.

　　3. Handling: When installing the hoop of the wet granulator, pay attention to the letters on the two ends of the hoop, and do "AA, BB, CC". Before installation, apply a layer of grease to both 15 ° sides of the hoop. , Thereby reducing the wear and tear caused by the hoop when the device starts and stops. When installing, first install the one with the positioning holes, and then install the other two. When tightening the screws, tighten the three screws evenly and gradually, and try to ensure the uniformity of the three gaps. After pre-tightening with a ratchet wrench, use the extended handle to gradually increase the force until it is tight.
