3.1 Comb design. The simpler lump breakers are using a system of static pins that are intermeshing with the teeth or blades of the agitator in order to break the lumps. The gap in between the comb of static pins (also called a breaker grid or breaker bars) and those of the agitator is determining up to which size the lumps will be crushed.
