Trommel With Gated Flow Diverters

A trommel assembly defining an axial direction, a radial direction, and a circumferential direction, the trommel assembly comprising:

• a trommel frame;
• a plurality of screen panels mounted to the trommel frame to define a material processing channel inside the plurality of screen panels along the radial direction, the material processing channel being configured for receipt of screening material;
• and
• a gate assembly mounted to the plurality of screen panels, the gate assembly extending into the material processing channel along the radial direction and comprising:
• a plurality of circumferential dams that extend substantially along the circumferential direction, the plurality of circumferential dams being spaced apart along the axial direction to define a plurality of screening stages;
• and
• a plurality of transfer gates, each of the plurality of transfer gates extending at a transfer angle relative to the circumferential direction between adjacent dams of the plurality of circumferential dams, wherein the plurality of transfer gates connect the plurality of screening stages such that rotating the trommel assembly advances the screening material through the material processing channel.
