Bolt on any discharge chutes that may have been shipped loose. Bolt on the
motor, motor base, drive belt and drive guard if these items have been shipped
loose. When installing the belt on the drive pulley ensure that if does not come off
the driven pulley. Ensure the belt is properly aligned and that the axis of the
motor remains vertical.
BELT TENSION
Proper belt tension is vital. V-belt drives must be taut at start-up and must be
checked again after the first hour of operation. Use standard tensioning
procedures for V-belts.
After the belt has been properly tensioned, it is imperative that all the motor bolts
be torqued to the maximum. This includes the pivot bolts and tension rods.
Failure to do proper torquing may result in serious damage.
Ensure that the entire drive guard assembly is bolted firmly in place.
Run a flexible rubber-sheathed power cable to the motor that allows for the
motion of the screen. A draped loop about 2 feet in length is adequate. Since the
motor shakes with the screen, ensure that all connections in the conduit box are
solid and secure to prevent movement. Motor direction is not critical although
material “drift” can be altered by changing rotation.
A time-delay device must be incorporated in the start/stop circuitry. A delay of
approximately 2 minutes in duration will allow the machine to come to a complete
rest before restarting. It is imperative that the screen be started only if it is
completely montionless.
CLEARANCE
The screen requires room to freely swing in its orbit. Although the size of this
orbit is only 1 1/4” in diameter this motion is exaggerated at start-up and shut-
down. It is therefore essential that 4” of horizontal clearance be provided all
around the screen from all points on the screen. In its stationary position nothing
should be closer than 4” in a horizontal direction. Failure to provide proper
clearance will result in damage to the screen.
