The efficiency of the vertical mill combines grinding, grading and drying (when the material moisture is large). The vertical mill uses the material bed grinding principle to grind the material, which is 30% lower than the ball milling system. Therefore, in terms of grinding efficiency, the vertical mill is superior to the ball mill. Moreover, the vertical mill uses hot air to transport materials, and can control the inlet air temperature when grinding coarser materials (such as coal, slag, etc.), so that the product reaches the final moisture, and the vertical mill can dry the water by 12-15%. The material; even the drying ball mill can only dry the material with 3-4% moisture; this not only saves economic costs, but also saves time cost. Compared with the ball mill, the vertical mill process is relatively simple, and the capital investment is small. The vertical mill feeds the material directly through the hot gas stream through the separator. This saves the cost of the classifier and the hoist. The dust-containing gas is directly collected into the collector, so the vertical mill system has simple process, low failure rate, high operation rate and compact layout. The construction area is 70% of the ball mill, and the construction space is 50-60% of the ball mill; investment The cost is low. Compared to ball mills, vertical mill products have a higher degree of homogenization and higher purity. This is because the time taken for the finished powder to be classified during the vertical mill is short, and over-grinding is avoided. In addition, due to the unique working principle of the vertical mill, during the operation of the vertical mill, no metal is in direct contact with each other, the metal wear is small, and the pollution of the finished material is small. Vertical mill grinding adjusts the separator speed, wind speed and roller pressure to facilitate the convenient adjustment of product fineness. The ball mill is easy to over-grind, the limestone unit wear is generally 4-6 g/ton, and the ball mill is up to 500 g/ton. When white minerals are ground, the effect on whiteness is much smaller than that of ball mills. Sulfate is a compound composed of sulfate ion (SO42-) and other metal ions. It is an electrolyte, and most of it is soluble in water. Sulphate minerals are salts formed by the combination of metal elements (including ammonium) and sulfate. Because sulfur is a valency element, it can produce different minerals in different valence states in nature. When it combines the highest valence S6 + with four O 2 - to form SO42 -, and then with metal cations, it forms sulfate. In sulphate minerals, more than 20 metal cations are combined with sulfate. That is, sulfate containing sulfate is sulfate.

We are different! Talk about the vertical mill and the ball mill!
Vertical mills and ball mills are the first equipment that people think of when choosing a milling equipment, but what is the difference between the two, how should we choose? Next, we will introduce the difference between the two to everyone! 1. In terms of grinding efficiency: 2. In terms of energy consumption: In the case of the same raw material abrasiveness and product particle size, the power consumption of the vertical mill can be reduced by 30% to 50% compared to the energy consumption of the ball mill. 3. Process flow: 4. Quality aspects of the product:
