Operating
Turn the extruder into automatic operation. The extruder starts automatically,
when there is enough concrete in the feeder hopper, the base
molds are in a continuous line on the plate feeding conveyors, and the
operating switch has been turned to the Auto -position. The whole production
line forms an even operation chain. A disturbance in any of the
said machines may stop the whole line. For minimizing disturbances,
there have been built buffers between the machines.
Note! During the operation, occasional breaks must not last longer than
15 minutes. This time may be shorter due to the concrete mixture used,
ambient temperature etc.
Finishing
The feeder hopper is emptied by turning the switch Level sensor to the
0-position. The extruder (and the whole line) works as long as the switch
is kept in that position. When the feeder hopper is empty, turn the switch
Man-0-Auto to the 0-position.
Cleaning
Note! Do not use water for cleaning! Only mechanical (non-battering)
cleaning is permitted.
After the control switch of the main control board (MCB) has been turned
to 0-position, the upper frame of the extruder is detached and removed.
Before moving the upper frame, remember first to remove the feeder
hopper, if required, and unplug the vibrator and the mixer power cables.
Lower frame
The screws and the side boards must be carefully cleaned. The screws
and the rollers can be operated manually for cleaning (OS1 in the Man
position). The side boards that connected by hinges to the lower frame
are lifted up. The base mold is manually driven off from the rollers. After
the rollers have been cleaned, a new base mold is driven onto the rollers
and the side boards are lowered back to their position.
Upper frame
The following parts must be carefully cleaned and oiled with mold oil:
- feeder hopper (No hammering)
- mixer
- packing bar
- vibrating plate
