Abstract
A machine for coloring landscaping material is defined as having first and second mixing chamber segments in which liquid colorant is introduced into the first segment in the form of a liquid spray and into the second segment in the form of an aerosol. Paddles supported by arms secured to a rotating shaft are provided through the first and second segments to mix and convey the landscaping material during coloring. Increased tip speed of the paddles is provided by relatively longer arms in the second segment to enhance interaction between the landscaping material and the aerosol colorant.
