| 摘要 |
The invention provides a vibrator assembly (5) having a pair of vibrators (1 ) held in spaced apart relationship by a frame (10). A screen assembly (1), having a screen (2, 3) extending between a pair of side plates (4), is securable between the vibrators (11) to the frame (10). The frame (10) transmits loadings transverse to the side plates (4) directly between the vibrators (11) to avoid undesirable stresses being absorbed by the screen assembly (1).
