Embodiment 1

[0080] An energy-saving control method for a ball mill, comprising the following steps:

[0081] Set the control group: set the control variables, and then use the system to monitor the different working stages of the ball mill in use, and obtain the first set of control control curve Q0;

[0082] Correction control program: According to the content of the first group of control control curves, in the first correction, a certain speed is increased or decreased in different working stages to form a control curve Q1; the corresponding values ​​of Q1 and Q0 in the different working stages The energy consumption is compared, and the better control curve corresponding to the smaller energy consumption is selected as the second set of control control curves;

[0083] Obtain the optimal curve: repeat the above correction n times (n≥1, n∈N*), and compare the control control curve of the nth group with the control curve Qn at the nth correction to obtain the optimal curve under the condi...

Embodiment 2

[0088] This embodiment is an embodiment combined with a specific implementation manner on the basis of the above-mentioned embodiment 1. The parameters listed in this embodiment are only one of the specific implementation manners, and are not intended to be limitations of relevant operational implementation technical solutions.

[0089] A ball mill with a widely used charge is selected as the test object, and the lining materials are rubber, medium aluminum and high aluminum. The input material formula and the ball lining material are fixed as external factors, the ratio of raw materials, water and grinding body is fixed at 1:0.45:1.5 as a control variable, and the filling amount of ball stones is maintained at 50% of the volume of the ball Left and right, several optimal power consumption solution experiments were carried out.

[0090] The control target of the ball mill is to achieve the target particle size of 200 mesh. The motor system uses the same transmission system a...

Embodiment 3

[0100] This embodiment is an embodiment combined with specific implementation manners on the basis of the foregoing embodiments. The difference between this embodiment and the above-mentioned embodiments is that in some embodiments, the working stage is determined by a working stage monitoring system, and the working stage system includes: a vibration sensor, a sound sensor and a pressure sensor; the vibration Sensors, sound sensors and pressure sensors are located inside the ball mill. Because in different working stages, the distribution of materials in the ball mill is not the same, for example, the thickness and proportion of the materials distributed on the inner surface of the ball mill will be different. Such as image 3 As shown, (a)(b)(c) represent the start-up stage of the ball mill, the preliminary grinding stage and the mature grinding stage, respectively.

[0101] Therefore, in an optional implementation manner, the judgment of the ball mill start-up phase, prel...

Abstract

The invention discloses an energy-saving control method for a ball-milling machine. The energy-saving method comprises the following steps: setting a control group: setting a control variable, and then monitoring different working stages of the ball-milling machine in use by using a system to obtain a first group of control curves; correcting a control program: increasing or decreasing a certain rotation speed in different working stages in first correction according to the content of the first group of control curves to form a control curve; comparing energy consumption corresponding to different working stages, and selecting better control curves corresponding to lower energy consumption to serve as a second group of control curves; acquiring an optimal curve: repeating the correction toobtain the optimal curve under the condition of the control variable, and recording corresponding running parameters. Through the technical scheme, the optimal curve for the running speed and acceleration of a motor can be found, so that the aims of saving energy and increasing yield are fulfilled.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to an energy-saving control method for a ball mill. Background technique [0002] The following statements merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Ball mill is a grinding equipment widely used in industry. It mainly uses the extrusion force and shear force between the grinding media to crush the material. Therefore, the greater the mutual extrusion and friction inside the ball mill, the higher the grinding efficiency and the less power and energy consumption. The speed of the ball mill will have a huge impact on the grinding state inside the ball. Under the condition that the raw material and water ratio, ball lining and other external conditions are consistent, there is an optimal range for the speed and acceleration of the ball mill controlled by the motor. [0004] Due to its adjustable s...
