How to determine the optimal water content range of the vertical roller mill feed is an important measure to improve the grinding efficiency, and its range depends on the following factors: 1. When the fluidity of the material is good, the moisture content of the material can be appropriately increased. After adding fly ash, with the increase of fluidity, the requirement of slag moisture content can be slightly expanded. 2. When the material is stored for too long, even if the water content is the same, the viscosity of the grinding paste is high. Some ten-year-old tailings ponds will grind paste, even if the water reaches 0.8% paste 3. The smaller the caster opening in the seal diaphragm section of the vertical mill, the easier it is to block, and the water content of the material is appropriately increased by increasing the caster opening 4. The vertical mill has large air volume, high wind speed, high internal temperature of the mill, and the moisture content of the material can be

The main thing is to listen to the manufacturer's explanations to understand the processing materials, technology and other information of the equipment. So is the processing of ore material in the end three-ring medium-speed micro-grinding or ultra-fine grinding machine more suitable? According to the development of SBM's mining machinery manufacturing for decades, as a high-performance equipment

Since there are so many steel slag formations in the industry, how do you deal with these steel slags? Vertical mill processing steel slag as an excellent production process, what is the value of vertical grinding and grinding steel slag? Steel slag vertical roller mill drives the grinding disc through the reducer The material falls from the feed port to the center of the grinding disc through the feeder, and the hot air enters the mill from the air inlet. As the grinding disc rotates, the material moves to the edge of the grinding disc under the action of centrifugal force. When it passes through the annular groove on the grinding disc, it is crushed by the grinding roller and crushed. After the crushing, the material is brought up by the high-speed airflow of the wind ring at the edge of the grinding disc, and the large particles fall directly to the grinding disc. After re-grinding, when the material in the airflow passes through the upper classifier, under the action of the rotati

1. In the Stainless steel casting smelting reduction stage, firstly manganese (electrolytic manganese sheet 99.7, national standard) and DNA ferrosilicon, the early DNA can reach 65% - 80% of the oxygen in most molten steel. 2. For those stubborn oxygen, the initial deoxygenation process is already weak, and the temperature and deoxidation capacity determine that the initial deoxidizer has completed the task. So who will kill the remaining oxygen? The answer is: the final deoxygenation process! The final deoxidizer is generally a composite deoxidizer with two or more components. A lot of practice shows that when the composite deoxidizer contains various elements in molten steel, not only the operation and responsibility, but also The important thing is that they are also crowded, rather than single-handedly, which can significantly improve the deoxidation efficiency itself. Therefore, the composite deoxidizer product is designed, how to think about 1 + 1 = 3 is a very important desig

The sandstone factory in summer is the real peak of the summer heat. Under such weather conditions, the frequency of failure of crusher equipment is much higher, mostly because the weather is too hot, causing the high temperature operation of the crusher equipment plus the crusher equipment. The inspection of the maintenance personnel was not in place. Today, the solution for the hammer hammer chuck of Zhejiang Hammer Crusher is solved! The cause of the vibration caused by the hammer crusher is generally the occurrence of cracks on the foundation, the loosening of the anchor bolts, the wear of the bearings, and the breakage of individual hammerheads to cause the crusher to lose balance and generate vibration. The maintenance personnel checked the above problems: although there were cracks in the basic part, the anchor bolts were not loose or broken. The two rolling bearings have no internal and outer ring phenomena, and the clearances are 0.6mm and 0.18mmmm respectively. Although the

Watch the entire process of the manganese ore production line to solve all the problems in your operation. As a kind of gravity ore dressing equipment, the manganese ore production line is mainly used for the beneficiation of fine, medium and coarse-grained mineral deposits. Regarding the mineral ore dressing power of fine-grained inlays, the combination of sulfur and iron in the large-scale pyrite mine is coarser, usually above 1mm. The selection of these ferro-irons can be directly sold to the sulfuric acid plant for profit. In the pyrite ore dressing, the Manganese processing plant is widely used, which can be used as a washing equipment for coarse-grain pyrite or as a fine-grained sulfur-sand sand selection equipment. Its mineral processing has also been recognized and shared by customers. Praise. When Sanjiu first started producing manganese ore production lines, we walked through the road of imitation, but we are constantly exploring and discussing. It is impossible to improve t

The role of high-efficiency sand making machine in engineering projects is becoming more and more important. As the demand for sand making machines increases, construction machinery is also constantly improving. As an important part of the sand production line, the sand making machine plays an important role in the whole production process. The stability and durability of the parts are also important, so care must be taken in the production of these parts. After the high-efficiency sand making machine is put into production, it is necessary to regularly clean up the blockage inside the product, and the blockage is excessive, which not only affects the output, but also affects the normal operation of the equipment. The wear of the wear block should also be known. If it is found to be worn, it should be repaired or replaced in time. Add grease at the right time and usually work for 400 hours. In the production process, it is a high-speed operation equipment, pay attention to safe produc

Slag is a by-product of ironmaking in blast furnace. In the process of ironmaking, iron oxide is reduced to metal iron, silica and alumina in iron ore at high temperature And other impurities and lime reaction to form silicate and silicoaluminate as the main components of the melt, after quenching into a texture of loose, porous particles, namely blast furnace slag, referred to as slag. Slag can be classified in different ways. According to the ratio of basic oxide (CaO+MgO) to acidic oxide (M), slag can be classified as basic slag (M> 1), neutral slag (M=1) and acidic slag (M< 1); According to the type of pig iron smelting, it can be divided into cast iron slag (slag discharged when smelting cast iron), steelmaking pig iron slag (slag discharged when smelting pig iron for steelmaking) and special pig iron slag (slag discharged when smelting pig iron with iron ore containing other metals, such as manganese slag and magnesium slag). According to the cooling method, physical proper
