HG6800TX Horizontal Grinder Features & Benefits

Productive and powerful

For enhanced flexibility within a single machine, a dedicated chip drum, adjustable for product size ranging from .125 in - 1 in (.3 cm - 2.5 cm), is available. 

The HG6800TX features low sidewalls to aid in feeding whole trees with minimal restriction, reducing the number of operator interactions with the material after loading and allowing the operator to focus on the next load. 

The Series III hardfaced duplex drum offers durability and convenient maintenance, with the ability to remove and replace single hammers and balance the drum externally.

Intelligent operation

The SmartFeed system monitors engine rpm and adjusts grinding speed for optimal machine performance.

The optional Damage Defense system reduces the likelihood of certain metal contaminants from entering the hammermill by reacting to the initial contact with the contaminant and reversing the feed system to allow removal of the contaminant.

An industry-leading, full-function, wireless remote control lets you adjust machine settings from the cab as conditions change, including control of the infeed settings, engine droop, conveyor height and more.  

Component access

Change screens efficiently utilizing the optional screen hoist and the remote control or main machine controls.
