Section II. DESCRIPTION AND DATA
The Roll Eagle Crusher Models 5230B, 5230C, and 5230D (figs. 1 and 2) are portable, self-contained
units used to crush and grade aggregate. A four cycle, six cylinder diesel engine operates the crusher roll

(under) conveyor, main (feed) conveyor, rotary elevator, and reciprocating feeder assembly. These
components are described in appropriate sections of this manual.
