[specific embodiment]
The present invention is further described below in conjunction with drawings and Examples.
Referring to Fig. 1, a kind of automatic control method for ball mill stable ore feeding comprises that PLC control system logic is judged and the control of 4～20mA analog quantity, and the control at host computer mine-supplying quantity configuration interface, the host computer mine-supplying quantity
The quantitative automatic ore control process of giving of ore grinding ball milling is divided four groups, respectively by 1 table grinder, and 2 belt conveyers, 4 disk feeders are formed 1 group, and the quantitative automatic ore deposit process of giving of remaining 3 groups ball milling is identical, describes with one group of automatic control process below.
Ball milling of the present invention is given ore deposit configuration Interface Control: as shown in Figures 2 and 3, it is that operating personnel import the processing parameter value according to producing the total mine-supplying quantity of the setting of needs in disk and belt flow process interface that ball milling is given the setting of ore deposit process mine-supplying quantity: as 48 tons/hour, this can adjust for the ore deposit parameter value according to producing needs at any time; 1#～4# disk is chosen to be disk and starts, 1#～4# disk is not elected disk as and is stopped, 1#～4# disk rotational frequency can be from 0 to 50Hz assignment, 1#～4# disk is regulated automatically and is closed to not selecting automatic regulatory function, disk is regulated automatically to be opened for and is selected automatic regulatory function, the selection of 1#～automatic regulatory function of 4# disk can only and have only a disk to be chosen in automatic adjusting open mode, the current real-time belt that is shown as of 1# electronic belt weighing is crossed the ore deposit amount, and 4 disk feeders start, stop, rotational frequency, automatically regulate and open, close and to make up according to producing needs; As: start 1#, 2# disk feeder, setting total mine-supplying quantity is 48 tons/hour, the 1# disk feeder is to regulate automatically, then selecting 1#, 2# disk in the startup of disk belt is selected is that disk is selected, the 1# disk is regulated automatically and is opened, setting total mine-supplying quantity input: 48 tons/hour, select running status chain promoter and automatic the adjusting.
Ball mill stable ore feeding control of the present invention is as Fig. 1, Fig. 2 and shown in Figure 4, ball mill stable ore feeding control is that total mine-supplying quantity parameter is set in input according to host computer, the feedback information of equipment running status and belted electronic balance is realized by the PLC control system, step is as follows: (1) is chosen in the 1SK switch automatically, (2) the not fixed total mine-supplying quantity input parameter value in host computer disk and belt flow process interface: 48 tons/hour, on be limited to 60 tons/hour, in the startup of disk belt is selected, select and to open, the disk feeder that stops, as: select 1#, the 2# disk is that disk is selected, 3#, the 4# disk is that disk does not select, selecting the 1# disk to regulate automatically opens, 2～4# disk is regulated automatically and is closed, 1#～4# disk rotational frequency is imported a desired value from 0 to 50Hz, this value can be revised at any time, select running status in chain promoter and adjusting automatically, host computer is connected communication by Ethernet with the PLC control system, (3) after the PLC control system receives that host computer is given the ore deposit signal, according to imposing a condition, output 1#, 2# disk frequency converter startup command, the frequency output of 2# disk frequency converter is with setting value output, the 2# disk feeder is just with this fixed-frequency rotating speed operation, the Automatic Frequency Control of 1# disk frequency converter be by PLC according to the feedback information of belted electronic balance with set total mine-supplying quantity and judge: if 1# electronic belt weighing be 62.4 tons/hour greater than setting 48 tons/hour of total mine-supplying quantities, then PLC control output low frequency rate signal is given 1# disk frequency converter, and the 1# disk feeder is in the slow-speed of revolution and moves to the ore deposit; If 1# electronic belt weighing be 35 tons/hour less than setting 48 tons/hour of total mine-supplying quantities, then PLC control output high-frequency signal is given 1# disk frequency converter, the 1# disk feeder is in high rotating speed and moves to the ore deposit; If 1# electronic belt weighing equates that with the total mine-supplying quantity of setting then the current frequency signal of PLC control output is given 1# disk frequency converter, the 1# disk feeder is in permanent rotating speed and moves to the ore deposit; More than three kinds of situations make carrying out to the ore deposit around setting total mine-supplying quantity all the time of disk feeder to the ore deposit, thereby realize the constant ore control of giving automatically, the mine-supplying quantity error is per hour in 0.5 ton/hour.
