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 semi-autogenous mill frequency control method, device and electronic equipment. Wherein, the method includes: determining the particle size distribution state of the grinding overflow product; determining the power change value of the semi-autogenous mill, determining the power state of the semi-autogenous mill based on the power change value; determining the load value of the semi-autogenous mill, Determine the load state of the semi-autogenous mill based on the load value; adjust the frequency of the semi-autogenous mill based on the particle size distribution state, power state and load state. Determine the particle size distribution state of the grinding overflow product, the power state of the semi-autogenous mill and the load state of the semi-autogenous mill, and adjust the frequency of the semi-autogenous mill according to the particle size distribution state, power state and load state. This method can realize the automatic adjustment of the frequency of the semi-autogenous mill without manual adjustment of the frequency of the semi-autogenous mill, which can save human resources and improve the efficiency and product quality of the semi-autogenous mill.

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 itself (or adding a small amount of medium) in the cylinder to continuously impact and roll down the 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 barrel. [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...
