HOW THE DRY COLORANT PROCESSING SYSTEM WORKS

• The process meters and applies dry colorant in the discharge area of the grinder during primary grind.
• This material can then be stockpiled or processed immediately
• During final grind, water is added in the grinder and the hammermill action drives the color deeply into the wood, resulting in brilliant colored product at production rates limited only by the capacity of the grinder.

GENERAL

Anyone with a Morbark tub grinder can color mulch with the inexpensive Morbark dispenser attachment.  The process impregnates color deeply into the wood fibre for long lasting premium mulch.  Messy, hard-to-handle liquid dyes are replaced with dry product. 

Traditional coloring machines are no longer required, and the cost of dry colorant is very economical.  Morbark still offers conventional coloring units for companies requiring that capability.
