Embodiment 1

[0030] see figure 1 A flow chart of a semi-autogenous mill frequency control method shown, the semi-autogenous mill frequency control method includes the following steps:

[0031] Step S102, determining the real-time particle size value of the grinding overflow product, and determining the particle size distribution state of the grinding overflow product based on the real-time particle size value of the grinding overflow product.

[0032] The above-mentioned semi-autogenous mill frequency control method is applied to the controller of the semi-autogenous mill. The autogenous mill in this embodiment can belong to the SAB semi-autogenous mill grinding process system, wherein the SAB semi-autogenous mill grinding process system includes a semi-autogenous mill. Self-grinding machines, vibrating screens and pump pools.

[0033] The drive of the autogenous mill is generally driven by an asynchronous motor or a synchronous motor, and it adopts unilateral transmission, double-sided t...

Embodiment 2

[0046] The embodiment of the present invention also provides another semi-autogenous mill frequency control method; this method is implemented on the basis of the method in the above embodiment; this method focuses on the specific implementation of determining the particle size distribution of the grinding overflow product.

[0047] Such as image 3 The flow chart of another semi-autogenous mill frequency control method shown, the semi-autogenous mill frequency control method includes the following steps:

[0048] Step S302, obtaining the grinding overflow product.

[0049] In this embodiment, the grinding overflow product can be detected in real time, which can also be called the grinding overflow product.

[0050] Step S304, classify the overflow products of the grinding based on the particle size diameter to obtain multiple types of overflow products.

[0051] The particle size diameter of the overflow product is not the same, and the overflow product can be classified ac...

Embodiment 3

[0094] Corresponding to the above method embodiment, the embodiment of the present invention provides a semi-autogenous mill frequency control device, such as Figure 4 A structural schematic diagram of a semi-autogenous mill frequency control device shown, the semi-autogenous mill frequency control device includes:

[0095] The particle size distribution state determination module 41 is used to determine the particle size real-time value of the grinding overflow product, and determine the particle size distribution state of the grinding overflow product based on the particle size real-time value of the grinding overflow product;

[0096] A power state determination module 42, configured to determine the power change value of the semi-autogenous mill, and determine the power state of the semi-autogenous mill based on the power change value;

[0097] The load state determining module 43 is used to determine the load value of the semi-autogenous mill, and determines the load sta...

Abstract

The invention provides a frequency control method and device for a semi-autogenous mill and electronic equipment. The method comprises: determining a fraction distribution state of an ore grinding overflow product; determining a power change value of the semi-autogenous mill and determining a power state of the semi-autogenous mill based on the power change value; determining a load value of the semi-autogenous mill and determining a load state of the semi-autogenous mill based on the load; determining the frequency of the semi-autogenous mill according to the fraction distribution state, the power state and the load state. The fraction distribution state of the ore grinding overflow product, the power change value of the semi-autogenous mill and the load state of the semi-autogenous mill are determined, and the frequency of the semi-autogenous mill is adjusted according to the fraction distribution state, the power state and the load state. The mode can adjust the frequency of the semi-autogenous mill automatically without adjusting the semi-autogenous mill manually, so that the manpower resource can be saved and the efficiency and the product quality of the semi-autogenous mill are improved.

Description

technical field [0001] The invention relates to the technical field of ore grinding, in particular to a semi-autogenous mill frequency control method, device and electronic equipment. Background technique [0002] Autogenous mills, semi-autogenous mills, ball mills and rod mills all belong to horizontal cylinder grinding equipment. The difference between the semi-autogenous mill and the ball mill and the rod mill is that the semi-autogenous mill crushes the material by means of the material being processed (or adding a small amount of medium) in the body through continuous impact and rolling grinding. In addition, it can be divided into autogenous mills and semi-autogenous mills according to the filling rate of steel balls in the mill body. [0003] In the SAB (Semi-Autogeneous mill / Ball mill, semi-autogeneous mill / ball mill) semi-autogeneous mill grinding process system, the user generally needs to manually adjust the frequency of the semi-autogeneous mill, that is, the us...
