[ technical field ] A method for producing a semiconductor device

the invention belongs to the technical field of ceramic production, and particularly relates to a ball stone proportioning method technology of a ball mill for grinding ceramic glaze.

[ background of the invention ]

The ceramic glaze ball mill is a key device for finely grinding ceramic glaze after being crushed. The ball mill for ceramic glaze is widely used for grinding mineral raw materials for manufacturing ceramic glaze, such as feldspar, quartz, talc, kaolin, and the like, to dry or wet grinding.

the ball stone in the ball mill mainly plays a role in impact crushing of glaze and also plays a certain grinding role. Therefore, the grading of the ball stones is to meet the requirements of both aspects. The grinding efficiency is directly influenced by the grinding effect, the yield of the ball mill is finally influenced, whether the grinding requirement can be met depends on whether the grading of the ball stones is reasonable or not, and the grinding requirement mainly comprises the size of the ball stones, the grade of the ball diameters, the proportion of balls in various specifications and the like.

The parameters are determined by considering the factors such as the specification and the size of the ball mill, the internal structure of the ball mill, the requirement of product fineness and the like, and also considering the characteristics (grindability, particle size and the like) of the grinding glaze.

in order for the glaze to be effectively crushed, several principles must be followed in determining the gradation:

First, the ball is impacted sufficiently to provide the ball with enough energy to break up the glaze particles, which is directly related to the maximum diameter of the ball.

Secondly, the pebbles have a sufficient number of impacts on the glaze, which is related to the filling rate and the average diameter of the pebbles. When the loading is fixed, on the premise of ensuring enough impact force, the diameter of the ball stone is reduced as much as possible, and the number of the ball stone is increased to improve the impact frequency to the glaze so as to improve the grinding efficiency.

Finally, the glaze material has enough residence time in the ball mill to ensure that the glaze material is fully crushed, which requires that the prepared ball stone has certain capability of controlling the flow rate of the glaze material.

[ summary of the invention ]

the invention aims to solve the technical problem of providing a ball stone proportioning method technology of a ball mill for grinding ceramic glaze, wherein the ball stone proportioning is reasonable, and the grinding efficiency is improved.

The invention is realized by the following steps:

selecting 4 kinds of ball stones with different ball diameters of the ball mill, adding the ball stones with different diameters into the ball mill according to the proportion and the glaze, starting the ball mill, and crushing the glaze by the ball stones in the ball mill and then finely grinding.

further, the diameter and the proportion of the ball grinding stone are as follows:

The ball millstone with the diameter of 60mm is as follows: 15 percent;

The ball mill stone with the diameter of 50mm is as follows: 25 percent;

the ball mill stone with the diameter of 40mm is as follows: 40 percent;

The ball mill stone with the diameter of 20mm is as follows: 20 percent.

further, the ball stone is a high alumina stone.

The invention has the advantages that: the four kinds of ball stones with different diameters are reasonably mixed and loaded in the ball mill according to a certain proportion, the weight of a big ball is large, the impact and collision effects on the glaze are large, and the breaking of large glaze is facilitated; the small balls have larger specific surface area than the large balls, and the extrusion and friction contact area with the glaze is increased. The four kinds of ball stones with different diameters are reasonably placed to obtain higher stacking density, the void ratio between the ball stones is reduced to the maximum extent, and the contact probability between the ball stones and the glaze is increased, so that the ball milling and fine crushing effect of the glaze is enhanced, and the ball milling and fine crushing efficiency is improved. The invention obtains the desired powder fineness by reasonably configuring the ball stones of the ball mill under the condition of shortening the prior grinding time. The invention shortens the grinding time, reduces the electric energy loss and improves the grinding efficiency.

[ detailed description ] embodiments

The invention provides a ball stone proportioning method technology of a ball mill for grinding ceramic glaze, wherein the ball stone is made of high alumina.

The invention adopts a formula calculation method and production practice summary to continuously adjust and improve the proportion of the ball stones so as to obtain a reasonable and accurate proportion.

referring to a calculation formula: d =28 (where D is the maximum frit grind in size and D is the maximum particle size of the initial pebble).

After the maximum diameter of the ball stone is calculated, only the reference ball diameter is still needed, and accordingly, four ball stones with different diameters can be initially matched, and are matched with the ball stones with different ball diameters of the traditional high alumina stone according to the principle that the middle is large and the two ends are small.

firstly obtaining an initial mixture ratio, then adding the mixture ratio into a ball mill to grind for a certain time, generally comparing with the existing grinding time, then detecting the fineness, wherein the fineness requires that the 325-mesh screen residue (overglaze) is less than 5 percent, if the fineness has a certain difference with the existing fineness, then adjusting the mixture ratio, and obtaining the desired powder fineness under the condition of shortening the existing grinding time.

Finally, obtaining an optimal ball stone diameter and proportion:

Pebble 60mm in diameter: 15 percent;

Pebble 50mm in diameter: 25 percent;

Pebble 40mm in diameter: 40 percent;

Pebble 20mm in diameter: 20 percent.

The ball stone is high alumina.

The invention adopts the ball stone proportions with different diameters, and obtains the desired fineness of the powder under the condition of shortening the prior grinding time. The invention shortens the grinding time, reduces the electric energy loss and improves the grinding efficiency.
