The compact Mix-Elvator is a medium-high production batch plant for proportioning of dry gunite materials at the jobsite. It can be towed behind existing vehicles and easily operated using push button controls. Maximum mixing capacity is 20 cu. yds. per hour, with a sand hopper capacity up to 45 cu. ft. and cement hopper capacity of 4 cu. ft. Combined with the Ridley C-10 gunite machine, the unit becomes a self-contained rig for construction and repair applications.
