Shale shakers with cartridge screen assemblies
First Claim
1. A system for vibratory separation of components of a material fed to the vibratory separator, the system comprisinga container into which material is feedable, the material including components to be separated by vibratory separation, the components including solids,a box within the container,vibratory isolation apparatus connected to the container, the box connected to the vibratory isolation apparatus,screening apparatus connected to the box for screening the material to separate solids from the material,the screening apparatus including a plurality of spaced-apart screening cartridges connected to the box, each cartridge having at least one fluid exit port from which fluid separated from the material by the screening cartridge passes from the screening cartridge,a vibrator connected to the box for vibrating the screening cartridges, andthe container having a fluid outlet from which separated fluid from the at least one fluid exit port of each screening cartridge flows from the system.
