Centrifugal fan structure: Sealed fans usually adopt centrifugal design, which can provide cold air with pressure higher than the primary air pressure to meet the sealing requirements of coal mills and feeders.
Application scenarios of sealed fans: Sealed fans are mainly used in coal mills and feeders of positive pressure direct blowing systems to prevent gas powder mixtures with coal powder from leaking out of the equipment, polluting the environment, or entering the spring loading device grinding roller bearings, causing bearing failures.
Types of sealed fans: According to different working conditions, sealed fans can choose different structural forms. For example, the carbon ring sealing structure can be selected according to the working conditions and process requirements to achieve maximum cost and benefit.
