2009 DURATECH TUB GRINDER OPERATING INSTRUCTIONS
WARNING: Loose clothing, necklaces and similar items are easily caught in moving parts. Avoid
the use of these items if possible. Keep long hair conned. Keep hands, feet and clothing away from
power driven parts.
1.6 Thrown objects and operator safety
An operational characteristic of all grinders is that objects may be thrown out of the hopper. Thrown objects may
present a safety hazard to persons in the area. This section is to inform the operator of this characteristic, and what can
be done to reduce the risk of injury to the operator and persons in the area. Keep all observers away from the machine.
Dimensioning the size of this area is not practical. The distance a thrown object may travel is dependent on several
conditions, including, but not limited to, rotor speed and diameter, condition of the hammers, style of hammers, object
mass, object shape, amount of material in the tub, and how the hammer strikes the object.
Figure 1.1
Figure 1.2
Figure shows an object being hit as
the hammer is on the upswing. A general
pattern for where thrown objects may
land is shown in Figure 1.2.
NOTE: The difference in the size of the area for side A versus side B. Side B is larger.
