The HG4000 Vermeer horizontal grinder has been redesigned. The 536-horsepower grinder has a feed table capacity of 4.6 cubic yards. The Series III duplex drum has reversible hammers and tips for extended wear life. The hard-faced anvil delivers cutting action with the drum, and a redesigned anvil-mount structure helps ease the hard-faced wear edge replacement process.
The feed roller has been updated with aggressive teeth and down pressure to maintain control of the fed material. A fully enclosed feed roller drive planetary helps provide protection and a tight clearance between the roller and mill housing to optimize material feeding while minimizing material catch points.
Working sound level is 112 decibels.
A wireless remote control allows operators to run most machine functions from up to 300 feet away. Operators can adjust infeed settings, engine speed droop, conveyor height, and more.
Service and maintenance enhancements have been incorporated into the redesign, including a drive belt tensioning system that does not require the engine to be moved when adjusting, large hinged side shields for optimal maintenance access, and added power rotation to the screen hoist for changing screens.
The Vermeer grinder has a transport width of 8.2 feet, a height of 13 feet, a fifth-wheel hitch trailer length of 32 feet, and a weight of 52,910 pounds.
