Latest Patents

One of Craig's latest patents involves a method for tramp material removal from pulp feed systems. This invention efficiently separates dense, tramp material from comminuted cellulosic fibrous material. By utilizing a generally vertical conduit and a slurry flow, which may be enhanced by high-speed liquid introduction, centrifugal force is employed to separate the tramp material into a cavity beneath the radius transition. This process does not require any mechanical elements to engage the slurry, making it a simple yet effective solution. The patent also discusses the potential for integrating tramp material separators into conventional metering screws or using centrifugal separators downstream of slurry pumps in chip slurry transport systems.
