Grinding machine need to meet following four comparison results with the presence or absence of the tripe trend that rises simultaneously:
The practical mine-supplying quantity of semi-autogenous mill is within the 98%-102% of the mine-supplying quantity setup parameter of the semi-autogenous mill of setting；
The actual power of semi-autogenous mill is lasting to rise or the aggregate power parameters of the semi-autogenous mill beyond setting in 30min
105%；
The jack-up pressure of semi-autogenous mill base bearing is lasting to rise or semi-autogenous mill base bearing beyond setting in 30min
Jack up the 105% of pressure parameter；
From the practical hard rock amount of semi-autogenous mill exhaust end loopback semi-autogenous mill feed end in 30min, continues to decline or be lower than
The 90% of the hard rock amount parameter of the slave semi-autogenous mill exhaust end loopback semi-autogenous mill feed end of setting.
9. semi-autogenous mill according to claim 6 rises, tripe judges and control method in advance, which is characterized in that the semi-autogenous mill
The tripe that rises judge in advance and rate-determining steps in, semi-autogenous mill exist rise tripe trend when, central data processing unit make semi-autogenous mill to
Mine amount setup parameter reduces the 20% of the mine-supplying quantity of semi-autogenous mill initially set, and makes the confluent setup parameter of semi-autogenous mill
Judge that semi-autogenous mill whether there is the tripe trend that rises again after increasing by 10%, 10min of the confluent of semi-autogenous mill initially set,
If it is, make again the mine-supplying quantity setup parameter of semi-autogenous mill reduce semi-autogenous mill initially set mine-supplying quantity 20%,
And make the confluent setup parameter of semi-autogenous mill increase semi-autogenous mill initially set confluent 10%.
10. semi-autogenous mill according to claim 9 rises, tripe judges and control method in advance, which is characterized in that described Semi-Autogenous
Machine rise tripe judge in advance and rate-determining steps in, as the mine-supplying quantity setup parameter of semi-autogenous mill reduces semi-autogenous mill initially set
The confluent setup parameter of 40% and semi-autogenous mill of mine-supplying quantity increases the 20% of the confluent of semi-autogenous mill initially set
Afterwards, semi-autogenous mill still has the tripe trend that rises, then central data processing unit adjusts the mine-supplying quantity setup parameter of semi-autogenous mill
It is zero.
