        and pressures are required to                                          call: 800.836.7068    visit: www.materialtransfer.com
        use inclines in dilute phase, but
        it can be done although perhaps
        the system will not be as robust.
        Lighter loading in the convey
        line requires less correction.
          In dense phase, the incline of
        the pipe appears important as
        compared to the slide angle of
        the material. When the mate-
        rial slide angle was significantly
        higher than the pipe angle, the
        impact of the incline was either
        null or a net benefit (1-2.3x the
        segment pressure) and no ad-
        ditional air is required. When
        the slide angle interferes with
        conveying, the impact flips to
        a detriment (4.5x the segment
        pressure) and significantly more
        air was required to convey the
        material up the incline. The rel-
        ative convey rate had little to do
        with the results. Overall, if the
        material slide angle is greater
        than the pipe incline angle then
        little or no additional airflow or
        pressure is required. If the op-
        posite is true regarding the slide
        angle, then additional air and
        pressure drop may be required.
