Grid Design and Waste Separation
topic
Grids are segment-shaped devices under opening assemblies, encircling 1/4 to 3/4 (usually 1/3 to 1/2) of the opening assembly. Grid elements include triangular section bars (most widely used), blades (strong and effective), angle bars, slotted sheets, and perforated sheets. Grid influence on cleaning comes from bar section, grasping effect, setting angle relative to opening elements, gap width, and overall surface area.
Role
The grid is the ultimate determinant of waste level and composition. Three basic adjustments are possible: distance from the beater, gap width between bars, and setting angle relative to the beater envelope. Modern waste chambers are passive (dead chambers) with no transport air passing through grid gaps.
