Feeding height of feederFeeding height of feeder
There are some other factors to consider: Under the ideal condition of the feeder's blanking height, the feed screw should be installed as close as possible to the top of the side feed opening to reduce the blanking height. If some loose material flows through the air, then it may become filled with air, so that its false density is greatly reduced after falling.
Feeder mixing type should ensure that the agitator in the filler feeder does not fluidize the filler. Many mixer manufacturers have designed special mixers for filler feeding. The hopper will introduce air into the extruder along with the filler. A chute hopper with an open top helps venting.
Assuming that your chute feed hopper has a solid cover with a round tube, and it is flexibly connected to the feeder, then you need to design an exhaust port. The chute of the hopper should be grounded to prevent static electricity. Some materials cause static electricity due to friction and cause the powder to hang on the wall of the hopper, thereby inducing the powder cake. A simple plan is to ground the hopper chute.
Tightening air blasters If cakes persist, special methods are often required. The hopper vibrator can be used, but it requires space and requires a device. An alternative plan is to install a blaster with an air nozzle, which is placed in the proper position of the chute and blows the cake before it grows.
