Abstract
(EN)
Vibratory screening machines (100) that include stacked screening deck assemblies (400) are provided. The vibratory screening machines include an outer frame (110), an inner frame (120) connected to the outer frame, and a vibratory motor assembly secured to the inner frame for vibrating the inner frame. A plurality of screen deck assemblies is attached to the inner frame in a stacked arrangement, each configured to receive replaceable screen assemblies. The screen assemblies are secured to respective ones of the plurality of the screen deck assemblies by tensioning the screen assemblies in a direction that a material to be screened flows across the screen assemblies. An undersized material discharge assembly is configured to receive materials that pass through the screen assemblies, and an oversized material discharge assembly having a deflector (1902) is configured to receive materials that pass over the screen assemblies.

L'invention concerne des machines de criblage à vibrations (100) qui comprennent des ensembles surfaces criblantes empilés (400). Selon certains modes de réalisation, au moins l'une des machines de criblage à vibrations peut comprendre un cadre externe (110), un cadre interne (120) relié au cadre externe et un ensemble moteur à vibrations fixé au cadre interne destiné à faire vibrer celui-ci. Une pluralité d'ensembles surfaces criblantes peuvent être fixés au cadre interne selon un agencement empilé, chaque ensemble surface criblante étant conçu pour recevoir des ensembles cribles remplaçables. Les ensembles cribles peuvent être fixés à des ensembles respectifs de la pluralité d'ensembles surfaces criblantes par tension des ensembles cribles dans une direction dans laquelle un matériau à cribler s'écoule sur les ensembles cribles. Un ensemble évacuation de matériau de calibre inférieur peut être conçu pour recevoir des matériaux qui traversent les ensembles cribles et un ensemble évacuation de matériau de calibre supérieur doté d'un déflecteur (1902) peut être conçu pour recevoir des matériaux qui passent sur les ensembles cribles.
