suitability for use in heavy-duty applications under heavy shock
loads. It also contains rust inhibitors, has high temperature
stability, and exhibits good water resistance.
Bearings should be lubricated with care. Too much grease applied
to the bearings at one time can rupture bearing seals. Under
normal operating conditions, a moderate amount of grease applied
every 2,000 hours should be adequate to ensure long life. Severe
operating conditions require more frequent lubrication
intervals.
5-4 Knife Recommendations and Adjustments
IMPORTANT!
The rotor and bed combs are subjected to severe conditions, and you should
inspect combs periodically for sharpness. The sharper the combs are kept, the
better the machine operates, producing quality regrind. If the combs become
severely rounded, chipped, or otherwise damaged, the granulator experiences
heavy shock loads during operation causing additional and significant reduction
in comb life.
