Magnetic separation machine starting, stopping what strict requirements?




Domestic mostly magnetic separator magnetic separator imitation from abroad come, for now the most common Jones-type magnetic separator, its starting, stopping all have strict rules.
(1) First of all equipment before starting the gold surface inspection, to ascertain the reason for the last shutdown, if it is shut down because of mechanical failures, must be considered in order to boot troubleshooting.
(2) after making sure that equipment (including electrical equipment) is correct, the first pair of running equipment (such as pumps and host) for turning, turning one week after discovery rotation flexibility, no stuck phenomenon, indicating operation site accessibility, or to check and remove obstacles.
(3). Opened before the host to open the water valve and observe whether there is clogging faucets, check the pressure gauge, which means that pressure must meet the requirements of the value. Neodymium Magnet
(4) Start pump. Start pump, you must first open the cooling water, the oil ministries valve opens, and then start pump. After careful to check the hydraulic pump startup is normal, if there is leakage around oil, etc., be sure to make oil to maintain normal circulation.
(5) start the host, is operating normally, plus exciting current, be careful not to add a rating and should be added to the specified current ascending gradually. Non-transfected host first water, non-transfected host after the first excitation is forbidden host with a load starts.
(6) Host normal operation and immediately after excitation to the mine, pay attention to the mine can not have wood residue and other debris, can not have more than tooth plate gap mineral particles, can not have strong magnetic minerals. Generally in strong magnetic separator should be preceded by the removal of the weak ferromagnetic minerals, and use a sieve to remove large debris and mineral particles, in order to prevent tooth plate gap blockage. In addition, the mass fraction of the mine should be appropriate to the amount of ore to be uniform.tube magnets
Taking these six boot sequence can be obtained as follows: a comprehensive inspection of a water supply and a lubricating oil pump starts a starting coil cooling pump a starting host an exciting one to mine.
Stop into normal shutdown (ie preparation of downtime) and emergency shutdown (ie unprepared sudden shutdown due to an accident) are two normal shutdown magnetic sure to load the machine and then handle clean shutdown, shutdown and boot sequence order opposite.
