Grinding system realizes automation and scientism
The grinding system consists of seven production lines, except the first production line, the other six production lines are identical. The first production line grinding system: The first production line grinding system including: SAG mill (including the feed chute, screen cylinder lubrication system); semi-autogenous mill and ball device; grade flow at the mine pump pool (including guitar frequency conversion to mine pump); classification cyclone Group at once; first magnetic separation; ball mill (including the feed chute, cylindrical sieve, lubrication system); second grade flow to the mine pump pool (including the frequency conversion to the mine pump); grade flow group; secondary magnetic separation; ball mill and ball device; stand mill; third grade flow to the mine pump pool (including the frequency conversion to the mine pump); third grade flow group; three magnetic election; mill stand and ball device.
Broken ore sent to the SAG mill feed chute via the feed belt conveyor installed in the chute on the level detector, when the material level reaches the upper limit set value, will give the computer control system to send alarm signals; material level reaches the high limit setting value, will the computer control system to send chain signal to stop the running of the SAG mill feed belt conveyor. In order to make a half since the mill to maximize grinding efficiency, and ensure the grinding quality, must ensure that the appropriate concentration of the semi-autogenous mill grinding. Humidity of the ore, return the amount of sand and return sand moisture changed little, according to the set in a half since the mill to the Division belt conveyor belt scale to measure the actual amount of ore to determine the semi-autogenous mill to the water Scaling in half since the mill’s water supply valve to adjust the SAG mill pulp density remained constant. SAG mill load, improve the efficiency of the SAG mill grinding, by the power transmitter and load sensors installed in the mill right half from the mill power and fill rate measurement, to measure the actual power and fill the slaughter and expectations compared to adjust the difference between the two semi-autogenous mill ore, to prevent the SAG mill overload or under load the phenomenon, semi-autogenous mill to The amount of ore to adjust the tape transport systems and stockpile.
Through the semi-autogenous mill cylinder screen to screen qualified pulp sent grading cyclone group to the mine pump pool sieve on large pieces of ore from the back to feed tape machine to return to the SAG mill to the ore chute re- grinding. Returning materials on the tape machine to set the speed of the belt conveyor detection, deviation switch, check blocking switch, Pull-wire emergency stop switches to complete the monitoring of the belt conveyor. The control system will provide remote and local are two control modes.
