Safety interlock system

l Emergency stop: Pressing the emergency stop switch immediately stops the equipment and cannot perform any operation

l Start low-speed stirring: can rotate while lifting the barrel

l High speed dispersion: the barrel can only rotate when it rises to the desired position

l Safety lock during operation: When the machine is running for mixing, the mixing drum cannot be lowered or opened.

l Preventing vacuum pipeline backflow: Special vacuum buffer tank design can effectively prevent the phenomenon of vacuum pump oil backflow to the mixing drum

l Operation fault stop: The frequency converter comes with overload, overcurrent, overvoltage, leakage, and phase loss protection

l Mixing bucket lifting: The mixing bucket can only be lifted after it is in place.

l The mixing drum cannot be lowered without vacuum discharge (without restoring normal pressure).

l The mixing bucket can only be started when it rises to the desired position and disperses at high speed.

l After the mixing bucket rises to the designated position, it is equipped with a locking protection system to prevent abnormal falling of the mixing bucket when it rises to the high position during operation.

l During the dry mixing stage, it is necessary to rotate the stirring paddle while lifting the bucket.
