How to calculate the ball mill steel ball ratio

Ball mill. The steel ball product has high hardness, low abrasion, good toughness and less crushing, the surface hardness of the ball mill steel ball will be further improved during use, the wear resistance of the ball mill steel ball will be enhanced, and the production capacity of the mill can be improved, and the specific surface area of cement can be improved.

and concentrate ** rate.

The technical department of our factory summarized some very wide range of ball mill problems in detail and gave answers. Yesterday I introduced to you how to judge the problem of bloated belly of the ball mill, and today I will introduce the problem of the ratio of steel balls of the ball mill? 1. Different ball mill models have different ball volumes.

For example, the MQG1500 3000 ball mill (processing capacity of 100-150 tons) has a maximum loading capacity of tons. 2. Add a steel ball for the first time (?120 and?

100) accounts for 30%-40, 80 in the ball accounts for 40%-30, small ball (?60 and? 40) accounted for 30.

3. Why only add 80 steel balls in the run-in process of the ball mill, because after the ball mill is installed, the ball mill teeth need to be meshed, and the processing capacity (ore volume) should be gradually increased, after the ball mill runs normally for two or three days, stop the ball mill to check the meshing of the large and small gears, and when everything is normal, open the ball mill manhole cover to add the remaining 20 steel balls for the second time.

The quality of Zibo Huaao steel balls is very good, you can ask their company.

The following is a simple calculation method used by well-known domestic ball mill manufacturers in practice, that is, the use of probability method and mathematical induction method for sampling calculation, which has some reference value, and is introduced as follows: make a box with a side length of 500mm with No. 8 steel wire, shake the inner material of the mill, open the grinding door to enter the mill, select the entrance and exit of the grinding bin, and measure 3 points along the radial direction, as shown in the figure.

The number of various steel balls exposed in the box is more than half a steel ball, and the data is sorted out and calculated to obtain a basically accurate ball mill steel ball gradation. A certain measurement of the ball mill steel ball with the following **. Specifications mm 100 95 95 85 85 75 75 65

Entrance (pcs) 28 36 27 18

Export (pcs) 24 20 40 25

Average 26 28

The theoretical total weight (100 95mm balls as 100mm balls) is calculated.

Proportion of various steel balls: The total filling amount of the mill is 22t, and the weight of the steel balls at all levels can be calculated (the weight table of the steel balls of the ball mill is as follows). Size (mm) 100 90 80 70

weight (t) then the weight average ball diameter can be calculated as: The average ball diameter of the calculated quantity is .

The calculation results are basically consistent with the actual situation, because the grinding fineness is too coarse at that time, when the grinding is stopped, according to the calculation, 100 95mm balls are picked out 5t, 90mm balls are added 1t, 80mm balls are 4t, and the fineness meets the requirements. Through the test, this method is more accurate, and it is effective to grasp the situation in the grinding and solve the problem.

Summary. Hello dear, how to calculate the ball mill steel ball ratio.

Pro, according to the fineness of your material feed and the diameter of the mill, as well as the concentration of slurry, lining plate and many other conditions, generally, the first stage of the mill according to 100 80 60 and other 3 to 4 types of steel balls, the second section can be 60 50 40 30 for proportion, the specific proportion needs to be subdivided according to your material situation. Stainless steel balls, carbon steel balls, low chromium steel balls are all available!

How to calculate the ball mill steel ball ratio

Hello dear, how to count the ball mill steel ball match pro, according to the fineness of your material and the diameter of the mill, as well as the slurry concentration, lining plate and many other conditions of comprehensive consideration, generally, a section of the mill according to 100 80 60 and other 3 to 4 types of steel balls, the second section can be 60 50 40 30 for proportion, the specific proportion needs to be subdivided according to your material situation. Stainless steel balls, carbon steel balls, low chromium steel balls are all available!

1. The diameter of the ball mill, the particle size of the inlet and outlet, and whether it is dry grinding or wet grinding, take these factors into account to calculate in detail what kind of high-alumina balls are needed and the ratio between them.

The ball mill is the key equipment for crushing the material after it is crushed. This kind of Shiqi pants type grinding machine is loaded with a certain number of steel balls as grinding medium in its cylinder.

It is widely used in cement, Portland products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation and glass ceramics and other production industries, dry or wet grinding of various ore pinnas and other grinding materials. The ball mill is suitable for grinding all kinds of ores and other materials, and is widely used in mineral processing, building materials and chemical industries, and can be divided into two grinding methods: dry and wet. According to the different discharge methods, it can be divided into two types: lattice type and overflow type.

Dear, hello, I am glad to answer for you, the size of the ball mill should be proportioned according to the size of the ball mill, the hardness of the grinding minerals, the feed particle size and the crushing performance of the grinding minerals. In general, the greater the hardness of the ball mill and grinding minerals, the larger the diameter of the required steel balls; At the same time, the feed size and grinding mineral crushing properties also affect the size of the required steel balls. When proportioning steel balls, it is recommended to refer to the recommended specifications provided by the manufacturer of the ball mill raw wax bucket, and fine-tune according to the actual situation.

At the same time, the size of the steel balls in the ball mill should not be too concentrated, and should try to conform to the distribution law within a certain range. A reasonable ratio of steel balls can ensure the normal operation of the ball mill, improve the production efficiency and the uniformity of the particle size distribution of grinding minerals. Dear, the above is mine, I hope these contents can help you, thank you for your understanding and support, I will continue to work hard.

Thank you, dear. I don't know the situation.

1. The basic principles of steel ball grading of ball mill 1. To deal with ore with large hardness and coarse particle size, it needs to have a large impact force, and it is necessary to load a steel ball with a larger size, that is, the harder the material, the larger the diameter of the steel ball; 2. The diameter of the mill is large, the impact force is large, and the diameter of the steel ball is small; 3. If a double-bin partition is used, the ball diameter should be smaller than that of a single-layer partition with the same discharge section; 4. Generally, there are four levels of balls, with few large and small balls and large balls in the middle, that is, "less at both ends and more in the middle.""。2. Factors to be considered when proportioning steel balls in ball mill 1. Equipment model, such as cylinder diameter and length; 2. Production requirements, that is, the user's standard for the grinding fineness of the material; 3. The property of the material refers to the initial particle size, hardness and toughness of the material to be grinded; 4. The size of the specification and the size of the specification should be paid attention to, and the large specification cannot be blindly pursued. 3. Ball mill steel ball adding skills The ball mill steel ball ratio should be judged according to the effective length of your mill, whether it has a roller press, how large the feed particle size is, what liner and structure are used, the expected sieve fineness and ratio table, how many chromium balls are used, how much rotation speed and other factors.

After the ball mill is installed, the ball mill gear needs to be meshed, and the processing capacity should be gradually increased.
