Countermeasures to powder bridging
Last time, I explained the main characteristics of the material. This time, we will mainly introduce bridging measures and recommended equipment.
Bridge breaker(Mixing blades)
We propose a lid with a bridge breaker like a mixing blade. Slow rotation of the blades breaks up material bridges in the hopper and promotes smooth flow. The shape and length of the blade are also manufactured according to the characteristics of the material. This is one of the most effective countermeasures against bridging.
Twin screw feeder
It is effective for materials that tend to become hard or sticky. The hardened material is pulverized and conveyed by the twin-screw feeder that rotates inside.
It is a device in which a stirring blade and a hopper are integrated. When feeding cotton or fiber, if the clumps are large to some extent, the clumps must be loosened before being discharged. This equipment is very effective for raw materials that cannot be loosened by ordinary mixing blades.
