First of all, too much steam will limit the feeding, which is manifested in that the steam will go out from the feeding port and hinder the feeding of materials into the screw. The steam will easily cause the powder to stick to the feeding port and gradually narrow, which will also affect the blanking. If volumetric feeding is used and there is no bridge-breaking equipment, raw materials can easily bridge in the hopper.
Secondly, when the moisture content is too high, carbon black is easy to agglomerate and not easy to disperse, which leads to the decline of product performance and the breakage of yarn in the later stage.
When the water content is too high, carbon black powder is easily released from the inlet and outlet due to water vapor removal, which pollutes the production environment.
