Baidu mining game eighth level

1. That is the pull of online games. There's too much for you. There is a "professional life online games" earlier pull. Well written. It's recommended

2. You can ask Du Niang

3. There was a movie Shennong before, but I watched it in the online library. It didn't seem to be finished, but it was deleted later...
there was another movie "all professional master" whose front is alien or online game prefix. I forgot, and my home was cut off before I finished watching it

4. Guide: ball mill is a very common grinding and mining equipment. Its grinding principle is to use the friction between the material and the steel ball or steel column and the rotation form of the rotating drum to make the material reach the ideal particle size standard, so as to facilitate the classification and flotation operation in the subsequent beneficiation process. Small series for you to introce the ball mill, then, as a central part of the ball mill grinding operation, whether there must be emphasis on the operation method? Here, Hongxing Machinery believes that as long as we master the nine word secret of high concentration, large return sand and uniform feeding, we can achieve the most ideal grinding effect. It will be described in detail below. The so-called high concentration mainly refers to the mass fraction (pulp mass fraction), which is the percentage of ore mass (dry weight) and total pulp mass (ore + water) in the pulp. Here, the mass fraction refers to the pulp mass fraction (grinding mass fraction) in the grinding machine. Grinding mass fraction is an important factor that affects the proctivity of grinding machine. It determines the friction between grinding medium and ground material, pulp fluidity and effective density (density difference between medium and pulp). In the operation of the grinding machine, a higher grinding mass fraction is generally used, so that a layer of slurry can be attached to the surface of the medium, so as to enhance the grinding effect beneficial to the grinding. At the same time, there is a large amount of ore per unit volume in ore discharge, so the ore discharge is large. However, if the pulp mass fraction is too high, e to the increase of pulp density, the effective density, activity ability and striking effect of grinding medium will be weakened. At the same time, e to the high mass fraction, high viscosity, poor fluidity and rection of total ore discharge, the proctivity of grinding machine will be reced and even swelling will occur. Therefore, high concentration means to increase the grinding mass fraction within a certain range, which is concive to improving the grinding effect. On the other hand, we need to realize large sand return in the process of ball mill operation. In order to explain such advantages, first of all, let's talk about what is sand returning. Return sand refers to the coarse-grained fraction returned by the classifier to the grinder for regrinding ring closed-circuit grinding. The amount of return ore is often several times of the original ore feeding. The ratio of return sand quantity to raw ore feeding quantity is called return sand ratio. Practice has proved that the return sand ratio will directly affect the proctivity of the mill. The larger return sand ratio increases the total feeding capacity of the mill, thus increasing the discharge speed of the mill, shortening the residence time of materials in the mill and speeding up the circulation. In addition, although the returned sand is coarse-grained ore, it is finer than the raw ore after all, so the total feed particle size composition of the mill becomes finer, and the comprehensive results are concive to improving the proctivity of the mill. The relationship between the return sand ratio and the relative proctivity of the mill was studied. It can be known that within a certain range (such as between 100% and 500%), with the increase of the return sand ratio, the proctivity of the mill will increase. When it reaches a certain value, the proctivity increase is very small, and the total feeding capacity of the mill is close to the maximum throughput, which is easy to cause ball mill swelling. Therefore, the sand return ratio should be kept stable and close to a constant value. Finally, in the process of ball mill grinding operation, we should also pay attention to the situation is the average feeding. Why do you say that? In fact, there are two main implications: one is that the feeding speed (ore quantity fed into the mill per unit time) is constant; The second is that the particle size composition of ore feed is uniform. In order to improve the grinding efficiency, the ore feed should be continuous, uniform and stable at a high level. More time and less time will make the mass fraction in the mill fluctuate frequently, which is not concive to the grinding process. Particle size segregation of grinding feed often occurs in the silo, the middle is fine, and the surrounding is coarse, which is easy to cause uneven feed composition. If the operation can not be adjusted in time according to the particle size, swelling will occur. Therefore, multi-point discharging and feeding should be adopted as far as possible. As long as you master the above ball mill operation specifications, or the experience and lessons learned by predecessors through personal practice, you can make the ball mill work in the best working condition all the time. The core problem revealed by the nine word secret is the balance of input and output efficiency.

the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless
