<p>A modular screening system includes a plurality of screening modules (1) supported in an interlocking manner on clamping bars (16) which are secured to and positioned across a screening machine in parallel spaced relationship. Each module (1) has a plurality of openings extending through it and a peripheral portion defined by side and end walls (4, 5; 2, 3). The side and end walls (4, 5; 2, 3) of each module (1) are provided with interengaging means (17; 14) which interlock with longitudinal and transverse channels (29; 15) in the clamping bars (16) to secure the module (1) in the machine. The end walls (2, 3) or each module (1) may also be provided with additional interengaging means (10; 11) whereby the modules (1) interlock together. </p> |
