Description

Technical Field

[0001] This utility model belongs to the field of mineral processing and relates to a system in which a tower mill and a ball mill share a single hydrocyclone. Background Technology

[0002] Before separation and flotation of copper-sulfur mixed concentrate, it is usually necessary to classify the copper-sulfur mixed concentrate and the mill discharge. The classified underflow is regrinded to achieve monomer liberation, which is beneficial to improve the copper-sulfur separation effect. The overflow from the classification enters the separation flotation process. In the regrinding process of the mixed concentrate, either a tower mill or a ball mill is usually used for the regrinding operation. However, each type of equipment has its advantages and disadvantages: tower mills have low energy consumption but also lower grinding efficiency; ball mills have higher energy consumption but relatively higher grinding efficiency. Therefore, depending on the ore properties and production mode, it is necessary to decide which type of mill to use. In the current traditional process, tower mills and ball mills are usually equipped with independent hydrocyclone classification systems. Two sets of grinding-classification systems usually lead to problems such as increased equipment investment and maintenance costs, crowded plant space, and cumbersome daily production operations.

[0003] In practical applications, having two different mills with two independent classification systems can lead to the following:

[0004] 1. Daily production operations are more complicated;

[0005] 2. The equipment occupies an increased area;

[0006] 3. Increased equipment investment and maintenance costs;

[0007] 4. The cramped space and complex, intertwined pipes inside the factory affect the passage of people, making them prone to bumps or falls. Utility Model Content

[0010] The height of the hydrocyclone is greater than the height of the ball mill and the tower mill, and the height of both the ball mill and the tower mill is greater than the height of the pump tank.

[0012] The underflow outlet is located on the bottom wall of the hydrocyclone, and the sideflow outlet is located on the side wall of the hydrocyclone and adjacent to the bottom surface of the hydrocyclone.

[0013] The outlet of the pump pool is connected to the inlet of the hydrocyclone.

[0014] As an improved technical solution of this application, a third buffer box is also included, wherein the feed inlet of the third buffer box is connected to the second buffer box and the discharge outlet is connected to the ball mill.

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the scope of the present application. Unless otherwise defined, the technical terms or scientific terms used herein should be understood as the common meanings understood by those skilled in the art.

[0027] Definitions:

[0028] The underflow port is arranged on the bottom wall of the hydrocyclone 1.

[0029] The side flow port is arranged on the side wall of the hydrocyclone 1 and adjacent to the bottom surface of the hydrocyclone 1.

[0030] As shown in Figure 1 A system of a tower mill and a ball mill sharing a cyclone includes a hydrocyclone 1, a ball mill 7, a tower mill 9 and a pump pool 8.

[0031] The height of the hydrocyclone 1 is higher than the height of the ball mill 7 and the height of the tower mill 9, and the height of the ball mill 7 and the height of the tower mill are both higher than the height of the pump pool 8. The height of the hydrocyclone 1 is higher than the height of the ball mill 7 and the height of the tower mill 9, so that the settled sand of the hydrocyclone 1 can flow to the tower mill 9 or the ball mill 7. The height of the ball mill 7 and the height of the tower mill are both higher than the height of the pump pool 8, so that the discharged ore of the tower mill and the ball mill can flow to the pump pool 8.

[0032] The side flow port of the hydrocyclone 1 is communicated with the feed port of the tower mill 9 through a first buffer tank 3, and the discharge port of the tower mill 9 is communicated with the pump pool 8. The settled sand of the cyclone can flow to the feed port of the tower mill. The first buffer tank 3 is provided with a first gate valve 2 on the side of the discharge port. When the tower mill 9 is needed to be used, the first gate valve 2 is opened, the second gate valve 4 is closed, and the settled sand of the hydrocyclone flows to the tower mill 9 after entering the first buffer tank 3. At the same time, when the tower mill 9 is not working, the settled sand will fill the gap between the gate plate and the buffer tank, preventing the leakage of the ore pulp.

[0033] The underflow outlet of the hydrocyclone 1 is connected to the feed inlet of the ball mill 7 via a second buffer tank 5; the discharge outlet of the ball mill 7 is connected to the pump tank 8; a second gate valve 4 is provided at the feed inlet of the second buffer tank 5. In some embodiments, a third buffer tank 6 is also included, the feed inlet of which is connected to the second buffer tank 5, and the discharge outlet of which is connected to the ball mill 7. The third buffer tank 6 serves as a buffer and facilitates the addition of steel balls to the ball mill 7. When the ball mill 7 needs to be used, the second gate valve 4 is opened and the first gate valve 2 is closed. The sediment from the hydrocyclone 1 enters the second buffer tank 5 and flows by gravity to the third buffer tank 6, and then by gravity to the ball mill 7.

[0034] In order for the sediment from the hydrocyclone 1 to flow by gravity to the ball mill 7, the height of the second buffer tank 5 is higher than the height of the third buffer tank 6, and the height of the third buffer tank 6 is higher than the height of the ball mill 7.

[0035] The discharge port of the pump pool 8 is connected to the hydrocyclone 1 via a pump to achieve overall reflux of the settled sand.

[0036] As an improved technical solution of this application, the size of the third buffer box 6 is smaller than the size of the second buffer box 5. The second buffer box 5 is slightly larger in size, so as to allow a certain amount of mineral to accumulate at the bottom of the second buffer box 5 and reduce wear on the second buffer box 5.

[0037] As an improved technical solution of this application, the size of the first buffer box 3 is smaller than the size of the second buffer box 5.

[0041] A circular opening (side outlet) with a diameter of 30 cm is made at the position of the sedimentation box (side of the bottom outlet) of the hydrocyclone 1. The first buffer box 3 is welded and the first gate valve 2 is set at the position of the feed pipe of the tower mill 9 connected to the first buffer box 3.

The underflow port is connected to a sedimentation pipe. The sedimentation pipe is provided with a second gate valve 4 and a second buffer tank 5 at a distance of 20 cm from the underflow port.

[0043] When the tower mill 9 needs to be used, the first gate valve 2 is opened, the second gate valve 4 is closed, the cyclone sand enters the first buffer tank 3 and then flows to the tower mill 9, the tower mill 9 discharges the ore which flows to the pump pool 8, the ore in the pump pool 8 is pumped to the hydrocyclone 1 for classification, and the overflow of classification is subjected to copper-sulfur separation flotation.

[0044] When the ball mill 7 needs to be used, the second gate valve 4 is opened, the first gate valve 2 is closed, the hydrocyclone 1 sand enters the second buffer tank 5 and then flows to the third buffer tank 6 and then flows to the ball mill 7, the ball mill 7 discharges the ore which flows to the pump pool 8, the ore in the pump pool 8 is pumped to the hydrocyclone 1 for classification, and the overflow of classification is subjected to copper-sulfur separation flotation.

[0045] The first buffer tank 3 has a length, width and height of 40cm, 30cm and 60cm respectively, the second buffer tank 5 has a length, width and height of 100cm, 100cm and 50cm respectively, and the third buffer tank 6 has a length, width and height of 60cm, 60cm and 60cm respectively.

The equipment investment, land area and maintenance cost are saved; 4. The space occupied by the pipeline is reduced, the production environment is more tidy, personnel passing is facilitated, and the safety risk is reduced.

[0047] Although the application has been disclosed as above with preferred embodiments, it is not intended to limit the application. Those skilled in the art can make various modifications and decorations without departing from the spirit and scope of the application. Therefore, the protection scope of the application is defined by the claims.
