摘要： A rotary drum mixer mixes product matter in a particulate form. A scoop section for the mixer has scoop blades which are radially enclosed by a peripheral wall which rotates with the drum. A stationary hood includes an outer face portion which covers the end wall of the scoop section and a peripheral portion which covers the peripheral wall of the scoop section, but neither the outer face portion nor the peripheral portion of the stationary hood contact product matter. The scoop blades are relatively flat and are angled into the direction of rotation. A back section is also included for the scoop blades. A seal assembly is positioned toward the inner diameter of the scoop blades and biases radially outward. The seal assembly may alternatively be positioned at the outer diameter of the scoop section, and/or the seal member may alternatively be biased radially outward. An inflatable bladder is used to radially bias the seal member against a hoop. Either the hoop may rotate with the scoop section and the seal member maintained stationary, or the seal member may rotate with the scoop section and the hoop maintained stationary.
摘要翻译：旋转鼓混合器将产品物质以颗粒形式混合。用于混合器的勺部分具有铲斗，其由与滚筒一起旋转的周壁径向封闭。固定罩包括覆盖勺部的端壁的外表面部分和覆盖勺部的周壁的周边部分，但是固定罩触点产品的外表面部分和周边部分都不重要。勺子叶片相对平坦，并且与旋转方向成角度。勺叶还包括后部。密封组件朝向勺子叶片的内径定位并径向向外偏压。密封组件可以可选地定位在勺部分的外径处，和/或密封构件可以可选地径向向外偏置。使用可膨胀的气囊将密封件径向地偏压抵靠箍。箍可以与勺部一起旋转，并且密封构件保持静止，或者密封构件可以随着勺部旋转并且箍保持静止。
