    • A screen assembly (10) for a horizontal screen machine has a screen body (12) diverging axially from an inlet end (13). A base wall portion (15) mounts the screen body (12) for rotation and includes eight substantially radial webs (16). An annular wall portion (21) is located adjacent the inner end (13) and includes drain passages (24) adapted to drain discontinuities in a bonding layer comprising a moisture cure polyurethane sealant/adhesive overlying the annular wall portion (21). Wear resistant tungsten carbide elements (26) include a plurality of apertures (27) extending through a wear face to a bonding face. Voids (32) in the discontinuous bonding layer (31) provide fluid interconnection between the apertures (27) and the drain passages (24). A replaceable screen member (33) is releasably secured at an inner ring frame (22) and an outer ring frame (36) of the screen body (12).
    • 一种用于水平筛机的筛网组件(10)具有从入口端(13)轴向分叉的筛体(12)。 基壁部分(15)安装用于旋转的筛体(12),并且包括八个基本上径向的腹板(16)。 环形壁部分(21)位于内端(13)附近并且包括适于排出粘合层中不连续性的排水通道(24),该粘合层包括覆盖在环形壁部分(21)上的湿固化聚氨酯密封剂/粘合剂。 耐磨碳化钨元件(26)包括穿过耐磨面延伸到接合面的多个孔(27)。 不连续粘合层(31)中的空隙(32)提供孔(27)和排水通道(24)之间的流体互连。 可更换的筛网构件(33)可释放地固定在屏幕体(12)的内环框架(22)和外环框架(36)上。
