Background technique

In the production process of cemented carbide, it is necessary to crush the material and forming agent through grinding and mix them evenly. In the existing technical solutions, the wet grinding process is often used, and the grinding solution such as alcohol and the forming agent such as paraffin are added to the wet ball mill together with the alloy material. After grinding into a slurry, the material is sieved and collected, and then dried and granulated. The above method has the following disadvantages: 1. The process is complicated, the turnover of production equipment is inconvenient, the labor intensity is high, and the efficiency is low. 2. The loss of grinding liquid is large, and when the molding agent is used in excess, it is easy to cause the screen to be blocked and the production efficiency to be low.

detailed description

As shown in Figure 1, a vertical cemented carbide wet ball mill includes a grinding chamber 1, a material forming chamber 2 and a drying chamber 3 which are sequentially connected from top to bottom. Under the action of gravity, the materials pass through the above structure in turn to complete the processes of wet grinding, fine grinding and mixing, screening and drying. The degree of automation is high and it is beneficial to reduce the labor intensity of production personnel.

The top of the grinding chamber 1 is provided with a feeding port 4 and a grinding liquid spray pipe 11 , the inside is provided with a first grinding medium 12 , and the bottom is provided with a first sieve plate 13 . The spraying method is used to inject the wet grinding liquid, which is beneficial to improve the contact efficiency between the material and the grinding liquid, and is conducive to saving the amount of grinding liquid and reducing the production cost.

The first sieve plate 13 is selected from 60 to 100 mesh. It is convenient to control the particle fineness in the grinding stage and reduce the agglomeration effect caused by excessive grinding.

The molding agent spray pipe 21 is arranged on the top of the material forming chamber 2 , the second grinding medium 22 is arranged inside, and the second sieve plate 23 is arranged on the bottom. The injection of forming agent by spraying is beneficial to improve the contact efficiency between forming agent and powder, and it is beneficial to control the amount of forming agent, avoiding the blockage of screen caused by excessive forming agent, thereby improving the efficiency of powder screening.

The second sieve plate 23 is selected from 180-300 mesh. It is convenient to control the final particle fineness of the powder.

The drying chamber 3 is provided with an air passage 31 and a discharge port 5 is provided at the bottom. It is beneficial to dry the material powder in time, prevent agglomeration, and ensure that the material is mixed evenly.

Set forth the specific implementation mode of the present utility model as follows by embodiment:

Materials are fed into the grinding chamber 1 through the feed port 4 . The grinding fluid spray pipe 11 is sprayed with alcohol as a wet grinding solution. Under the action of the cavity here and the first grinding medium 12 , the material is crushed to 100 mesh, and then falls into the material forming chamber 2 through the first sieve plate 13 .

In the forming chamber 2, the molding agent spray pipe 21 is sprayed with paraffin wax liquid at 70°C. The material is further pulverized under the chamber here and the second grinding medium 22, and the paraffin liquid is wrapped on the surface. After the pulverization reaches 300 mesh, the material powder wrapped with paraffin passes through the second sieve plate 23 and enters the drying chamber 3 .

The air passage 31 sends cooling gas into the drying chamber 3 to solidify the paraffin wax wrapped on the outer surface of the material powder, and the material powder is collected through the discharge port 5 .
