2009 DURATECH TUB GRINDER OPERATING INSTRUCTIONS
PROPER OPERATION OF THE TUB GRINDER:
• Do not grind materials any ner than necessary. Finely ground materials will produce more dust and
increase the risk of re. If nely ground materials are required, it is better to grind the materials coarse
rst with large opening screens installed in the grinder and then regrind them to the desired consistency
by installing smaller opening screens in the grinder. Be especially cautious when grinding materials that
can burn easily.
• When lling the tub grinder during start‑up begin by lling the front of the tub and avoid placing
materials on the spinning rotor. When material begins to fall over the rotor, set the governor control on
“Manual” and rotate the tub slowly while continuing to ll the tub. When the tub is 1/2 to 2/3 full, the
governor control can be set to “auto” and grinding operations can resume normally. Do not allow the tub
to stop for any signicant amount of time with material over the rotor to minimize frictional heating.
• Do not smoke when working with combustible materials.
REMOVAL AND CLEANING INSTRUCTIONS:
• Clean the engine compartment daily or more often if conditions require it be done more frequently.
When cleaning the engine compartment, always clean the top of the engine and the areas around exhaust
manifolds, exhaust plumbing and turbochargers.
• Check the rotor box for debris built up around the rotor. Remove material that may be packed tight near
the bearings, on shaft or other rotating components because it will become hot due to friction.
• At shutdown, always clean and remove all dust, debris, or combustible material off the entire grinder. Use
high‑pressure air or water if necessary. Always move the grinder and all other equipment away from the
ground material pile before leaving the job site in case of smoldering combustion in the ground material.
TUB GRINDER MAINTENANCE:
• Repair any fuel or hydraulic leaks as quickly as they are discovered.
Clean up spills immediately. Fuel or oil soaked materials can contribute
signicantly to the rapid spreading of a re once it has begun.
• Inspect all electrical wiring periodically. Any chafed or damaged wires
should be repaired immediately. Keep all electrical connections tight to
prevent arcs or sparks.
• Contact between the rotor and any stationary component of the grinding
chamber such as contact between the hammers and the screens must be
corrected immediately.
