below and disposed laterally rearwardly from the spray bars 176 178 180 and transverse to the front to rear flow path of material through the milling chamber 118 and an ejection conveyor 188 is mounted at the lower end of the mill chamber 118 below the milling rotor 184 a set of generally vertically extending finger bars 189 is mounted in the upper end of the mill chamber 118 laterally rearwardly of the milling rotor 187 the upper end of the finger bars 189 are rotatably secured to the mill chamber 118 and a spring 191 biases the finger bars into a generally vertical position toward the milling rotor 187 and its associated blades in this fashion the finger bars 189 simultaneously urge material flowing through the mill chamber 118 toward and into milling contact with the milling rotor 187 and its milling blades the ejection conveyor 188 is rotatable upwardly at its rearward end 190 and delivers or ejects the sprayed and milled material off of the rearward end 190 onto the surface e g earth supporting the mobile apparatus 100 the main conveyor 114 milling rotor 187 and ejection conveyor 188 are all driven by the engine on the mobile apparatus 100 in a fashion well known to those skilled in the art the preferred method and apparatus are designed to work well in remediating contamination found in construction or demolition debris as well as contamination found in soil moreover the method and apparatus are designed to work in remediating contamination found in a given mass that is a mixture of soil and debris for example as.
