Detailed description of the invention

The application's scheme is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.

Inventor finds through long-term research, and in prior art, why inaccurate the mine-supplying quantity of ore mill spatial load forecasting regulates, and is because ore mill load condition is only determine according to the mill sound of ore mill.Mill sound refers to the noise that ore mill produces, and its amount in decibels is higher, then the loading of expression ore mill Mineral Material is less, then the volume of ore mill and the ratio of mineral aggregate loading larger, then represent that the load of ore mill is less.But, because in actual production complicated and changeable, the noise of ore mill is subject to many-sided interference, relation between mill sound and ore mill load is not changeless, therefore, the interference that will be subject to due to mill sound by the ore mill load condition determined of mill sound and changing, what cause ore mill load condition to judge is inaccurate.

Research and analyse based on the above-mentioned of inventor, the main thought of the application is: no longer only determine the load condition of ore mill according to mill sound, but comprehensively determines according to the main shaft oil pressure of ore mill, mill power and mill sound three.Because main shaft oil pressure and mill power can't be subject to the impact of actual complex operating mode as sound, the impact that the load condition of ore mill is just subject to actual condition will be corrected and can more accurately determine, thus makes the spatial load forecasting of ore mill more accurate.

It should be noted that, noun " ore mill " involved herein, expression be the grinding attachment used in the grinding process of ore-dressing technique, also can be described as " grinding machine ".Wherein, the technical scheme of the embodiment of the present application is applicable to multiple different grinding attachment, such as ball mill or semi-autogenous mill.

After the basic thought describing the application, below in conjunction with accompanying drawing, described in detail the specific implementation of the method and apparatus that the application's ore mill mine-supplying quantity controls by embodiment.

See Fig. 2, show the basic flow sheet of the embodiment of the method 1 that ore mill mine-supplying quantity controls in the application.In the present embodiment, described method such as can comprise the following steps:

Mill sound-like state value, main shaft oil pressure and mill power that S201, acquisition ore mill are current, and calculate mill load parameter according to described mill sound-like state value and mill power.

In the present embodiment, the mill sound that mill sound-like state value is detected by ore mill calculates and draws.Such as particularly, a kind of obtain manner grinding sound-like state value, can as shown in Figure 3, have been come by following steps:

S301, by obtaining the signal of telecommunication of described mill sound detect to the mill sound detect of described ore mill.

S302, account for the signal proportion of signal spacing width according to the difference between signal higher limit and the current value of the described signal of telecommunication, determine the mill sound-like state value that described ore mill is current.

Wherein, described signal higher limit is the current value of the maximum signal of telecommunication of described ore mill mill sound detect, described signal spacing width is that described signal higher limit and signal roll off the production line the difference of value, and described signal lower limit is the current value of the minimum signal of telecommunication of described ore mill mill sound detect.Such as, usually, the current value of the mill sound signal of telecommunication detected is all in the scope of 4 ~ 20 milliamperes, the current value of the maximum signal of telecommunication is 20 milliamperes, and the current value of the minimum signal of telecommunication is 4 milliamperes, then signal higher limit is 20, signal lower limit is 4, and now signal spacing width is 16.

When determining mill sound-like state value according to aforementioned proportion, a kind of mode be can directly using aforementioned proportion as grinding sound-like state value.But the mill sound of ore mill is interfered sometimes, the quiescent current value that detection mill sound obtains has deviation, even can exceed signal higher limit or not reach signal lower limit.In order to the impact making the mill sound-like state value determined avoid interference, another kind determines that the mode of grinding sound-like state value can be the signal proportion that the difference first calculated between described signal higher limit and the current value of the described signal of telecommunication accounts for described signal spacing width, with the second corrected parameter preset, described signal proportion is revised again, obtain the mill sound-like state value that described ore mill is current.Like this, utilize the second corrected parameter to revise aforementioned proportion, thus the impact of interference can be alleviated.Particularly, such as following formula can be adopted calculate mill sound-like state value:

$\mathrm{YI}=100\×\frac{(X_{\max }-X)}{X_{\max -\min }}+{\mathrm{KD}}_2;$

Wherein, YI is mill sound-like state value, and X detects the current value grinding the signal of telecommunication that sound obtains, X _maxfor signal higher limit, X _max-minfor signal spacing width, KD ₂be the second corrected parameter, wherein, KD ₂it can be the constant pre-set.

Then Fig. 2 is returned.

In the present embodiment, mill load parameter be according to mill sound-like state value and the common matching of mill power calculate one for judging the parameter of mill load state.Such as, a kind of account form of mill load parameter, can as shown in Figure 4, be come by following steps:

S401, calculate described mill sound-like state value and account for the mill signal to noise ratio example of maximum mill sound-like state value and described mill power accounts for the power proportions of maximum mill power;

S402, basis are weighted average result to described mill signal to noise ratio example and described power proportions, obtain described mill load parameter.

Wherein, if mill sound-like state value calculates in the mode shown in aforementioned Fig. 3, then in fact grind a sound-like state value very ratio, maximum mill sound-like state value is 1.Also namely, described mill sound-like state value accounts for the mill signal to noise ratio example of maximum mill sound-like state value, is in fact described mill sound-like state value.Therefore, in present embodiment, mill sound-like state value also directly can be adopted as mill signal to noise ratio example to perform step S402.

For the mode according to average weighted result determination mill load parameter, a kind of mode can be that mill signal to noise ratio example is done weighted average with power proportions with identical weight.But the mill sound of ore mill is interfered sometimes, the quiescent current value that detection mill sound obtains has deviation, the reliability standard of mill sound-like state value is different, so, another kind of can mode be adopt the weight of coefficient of reliability to mill signal to noise ratio example and power proportions preset to distinguish, and then is weighted on average mill signal to noise ratio example and power proportions with different weights.In addition, even if having employed coefficient of reliability, still may there is metrical error in grinding machine state value and mill sound power, and in order to eliminate this error, another mode can be first be weighted on average according to the coefficient of reliability of ore mill detection signal to described mill signal to noise ratio example and described power proportions, obtain result of weighted average, then with the first correction factor preset, described result of weighted average is revised, obtain described mill load parameter.Like this, utilize the first corrected parameter to revise aforementioned proportion, thus the impact of error can be alleviated.Particularly, following formula such as can be adopted to calculate mill load parameter:

$\mathrm{FH}=\frac{\mathrm{JI}}{{\mathrm{JI}}_{\max }}\×a+\mathrm{YI}\×(1-a)+{\mathrm{KD}}_1;$

Wherein, JI is mill power, JI _maxfor maximum mill power, YI is mill sound-like state value, and a is default coefficient of reliability, KD ₁be the first corrected parameter, wherein, the preferred span of a is 0.4 ~ 0.6, KD ₁it can be the constant pre-set.

Then Fig. 2 is returned.After S201 is finished, then perform S202.

S202, the oil pressure number range belonging to described main shaft oil pressure and the load value scope belonging to described mill load parameter, determine the oil pressure state that described ore mill is current and load parameter state.

Particularly, the determination mode of oil pressure state and load parameter state can be such as: if described main shaft oil pressure is less than or equal to the first oil pressure threshold value, and described ore mill is current is in low oil pressure state, if described main shaft oil pressure is less than the second oil pressure threshold value and be greater than the first oil pressure threshold value, described ore mill is current is in reasonable oil pressure state, if described main shaft oil pressure is more than or equal to the second oil pressure threshold value, described ore mill is current is in high oil pressure state, if described mill load parameter is less than or equal to the first load parameter threshold value, described ore mill is current is in underload parameter state, if described mill load parameter is less than the second load parameter threshold value and be greater than the first load parameter threshold value, described ore mill is current is in Reasonable load parameter state, if described mill load parameter is more than or equal to the second load parameter threshold value, described ore mill is current is in high load capacity parameter state, wherein, described second oil pressure threshold value is greater than described first oil pressure threshold value, described second load parameter threshold value is greater than described first load parameter threshold value.

It should be noted that, the first oil pressure threshold value and the second oil pressure threshold value can set according to the maximum oil pressure of ore mill, and such as, the first oil pressure threshold value can be the 85%, second oil pressure threshold value of maximum oil pressure can be 95% of maximum oil pressure; Similarly, first load parameter threshold value and the second load parameter threshold value can be set according to the maximum mill load parameter of ore mill, such as, the first load parameter threshold value can be the 80%, second load parameter threshold value of maximum mill load parameter can be 90% of maximum mill load parameter.

S203, be in higher load condition in response to described ore mill is current, reduce the mine-supplying quantity of described ore mill.

Wherein, described higher load condition comprises following three kinds of situations:

(1) described ore mill is current is in high oil pressure state and high load capacity parameter state simultaneously;

(2) described ore mill is current is in high oil pressure state and Reasonable load parameter state simultaneously;

(3) described ore mill is current is in reasonable oil pressure state and high load capacity parameter state simultaneously.

Be understandable that, described higher load condition comprises above three kinds of situations, refer to that above-mentioned three kinds of any one situations of situation can be referred to as higher load condition, as long as namely the main shaft oil pressure of ore mill and mill load parameter meet any one situation above-mentioned, just represent that ore mill is current and be in higher load condition.

It should be noted that, when each regulable control reduced mine-supplying quantity, a kind of possible control mode can be reduce mine-supplying quantity with fixed value, and before and after namely regulating, the difference (regulated quantity) of mine-supplying quantity is a fixed value.But in order to carry out mine-supplying quantity control more subtly, another kind of possible control mode can be that before and after namely regulating, the difference of mine-supplying quantity is comprehensively determined in conjunction with ore mill mill sound, main shaft oil pressure and mill power in conjunction with the current concrete oil pressure state of ore mill and load parameter state to determine the regulated quantity of mine-supplying quantity; Particularly, participate in Fig. 5, such as, can complete S203 by following steps:

S501, identify the current residing oil pressure state of described ore mill and load parameter state;

Be understandable that, after S501 is complete, the oil pressure state residing for identified ore mill and load parameter state determine that the arbitrary step entered in following S502 ~ S504 performs.

S502, be in high oil pressure state and high load capacity parameter state in response to described ore mill is current simultaneously, the mine-supplying quantity of described ore mill is reduced the first regulated quantity;

S503, be in high oil pressure state and Reasonable load parameter state in response to described ore mill is current simultaneously, the mine-supplying quantity of described ore mill is reduced the second regulated quantity;

S504, be in reasonable oil pressure state and high load capacity parameter state in response to described ore mill is current simultaneously, the mine-supplying quantity of described ore mill is reduced the second regulated quantity.

It should be noted that, described second regulated quantity is less than described first regulated quantity.Be in high oil pressure state and high load capacity parameter state when ore mill is current simultaneously, also namely the oil pressure of ore mill and mill load parameter all higher time, illustrate that now mineral aggregate is too much in ore mill, so what adopt in S502 is that first regulated quantity larger compared with S503, S504 the second regulated quantity is to reduce mine-supplying quantity, to make mine-supplying quantity to reduce rapidly, ore mill inner stuffing reduces rapidly.

Pass through present embodiment, when carrying out mine-supplying quantity to the ore mill being in higher load condition and regulating, state in conjunction with the mill sound of ore mill, oil pressure and mill power three determines the regulated value that mine-supplying quantity regulates, achieve and utilize the ore mill mine-supplying quantity of different regulated values to different load state to carry out corresponding adjustment, thus it is more accurate that ore mill mine-supplying quantity is controlled.

Then Fig. 2 is returned.

S204, be in low load condition in response to described ore mill is current, increase the mine-supplying quantity of described ore mill.

Wherein, described low load condition comprises following three kinds of situations:

(1) described ore mill is current is in low oil pressure state and underload parameter state simultaneously;

(2) described ore mill is current is in low oil pressure state and Reasonable load parameter state simultaneously;

(3) described ore mill is current is in reasonable oil pressure state and underload parameter state simultaneously.

Be understandable that, described low load condition comprises above three kinds of situations, refer to that above-mentioned three kinds of any one situations of situation can be referred to as low load condition, as long as namely the main shaft oil pressure of ore mill and mill load parameter meet any one situation above-mentioned, just represent that ore mill is current and be in low load condition.

It should be noted that, when each regulable control increased mine-supplying quantity, a kind of possible control mode can be increase mine-supplying quantity with fixed value, and before and after namely regulating, the difference (regulated quantity) of mine-supplying quantity is a fixed value.But in order to carry out mine-supplying quantity control more subtly, another kind of possible control mode can be that before and after namely regulating, the difference of mine-supplying quantity is comprehensively determined in conjunction with ore mill mill sound, main shaft oil pressure and mill power in conjunction with the current concrete oil pressure state of ore mill and load parameter state to determine the regulated quantity of mine-supplying quantity; Particularly, participate in Fig. 6, such as, can complete S204 by following steps:

S601, identify the current residing oil pressure state of described ore mill and load parameter state;

Be understandable that, after S601 is complete, the oil pressure state residing for identified ore mill and load parameter state determine that the arbitrary step entered in following S602 ~ S604 performs.

S602, be in low oil pressure state and underload parameter state in response to described ore mill is current simultaneously, the mine-supplying quantity of described ore mill is increased the 3rd regulated quantity;

S604, be in reasonable oil pressure state and underload parameter state in response to described ore mill is current simultaneously, the mine-supplying quantity of described ore mill is increased the 4th regulated quantity.

It should be noted that, described 4th regulated quantity is less than described 3rd regulated quantity.Be in low oil pressure state and underload parameter state when ore mill is current simultaneously, also namely the oil pressure of ore mill and mill load parameter all higher time, illustrate that now mineral aggregate is very few in ore mill, so what adopt in S602 is that three regulated quantity larger compared with S603, S604 the 4th regulated quantity is to reduce mine-supplying quantity, to make mine-supplying quantity to increase rapidly, ore mill inner stuffing increases sharply.

In addition, be understandable that, the 3rd regulated quantity in present embodiment shown in Fig. 6 can be adopt same numerical value with the first regulated quantity in the embodiment shown in earlier figures 5, similarly, the 4th regulated quantity in the present embodiment shown in Fig. 6 can be adopt same numerical value with the second regulated quantity in the embodiment shown in earlier figures 5.Certainly, above four regulated quantitys also can adopt different numerical value, such as, specifically can set according to actual condition.

In the actual moving process of ore mill, ore mill is sometimes neither in higher load condition and is not also in low load condition, but be in abnormal conditions, now, can also determine how the mine-supplying quantity of ore mill is controlled, such as, particularly, on the process base shown in Fig. 2 further combined with the mill sound situation of ore mill in the present embodiment, the present embodiment can also comprise further after S202: be in abnormal load state in response to ore mill, and the mine-supplying quantity maintaining described ore mill is constant.Like this, in abnormal cases, ore mill keeps mine-supplying quantity constant, waits for that the oil pressure state of ore mill and load parameter state change further, enters S203 or S204 again regulate until meet higher load condition or low load condition mine-supplying quantity.

Wherein, described abnormal load state comprises following two kinds of situations:

(1) described ore mill is current is in high oil pressure state and underload parameter state simultaneously;

(2) described ore mill is current is in low oil pressure state and high load capacity parameter state simultaneously.
