Notes for startup and shutdown of fish feed extruder

Stop and dismantle the machine: Normal downtime, extruding machine fault, stop, shut down in the following order when closing hopper discharge port ram, the feeder speed to zero, press the stop button and close the vacuum system, gradually reduce the screw rotation speed, if need to change the new material, as far as possible row all the remaining material inside the barrel, with basic construction materials, the host speed to zero, press the main motor stop button, Cut off the multiple power switches on the control cabinet of the main engine, cut off the main power switch on the main outlet, close the water inlet valve, and clean the machine.

Emergency stop fish feed extruder unit operation in twin-screw extruder, once there's an emergency, should immediately press the emergency stop button or stop button according to the fault section, usually make host outage, emergency stop to avoid by all means is immediately after the main motor and feed motor speed control knob set to zero, and shut down other auxiliary system, Restart the machine in the normal boot order after troubleshooting.

Fish feed extruder teardown steps, the same as the content of the single screw extruder, if there is heat sensitive material after downtime in extruder, usually need to adopt to the material being squeezed inside the barrel, in order to prevent the heating time is too long, before starting the next time lead to material overheating decomposition, clear teardown as needed, open machine should strike to loosen the nose flange removed filter plate mesh, and then start the screw, Run the remaining material in the extruder barrel, pull out the screw while it is hot, and then use the copper rod and copper shovel to quickly clean the head, the screw and the residual material in the barrel. The cleaned parts should be put in place in time. If the storage should be coated with a little anti-rust oil screw, and it should be hung when placed.
