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 rotating rotor, the coarse powder falls from the cone to the grinding disc and is re-grinded. The qualified fine powder is ground together with the airflow and collected by the dust collecting device. The product, containing moisture, is dried during contact with the hot gas stream, and can meet the requirements of different humidity materials by adjusting the hot air temperature. By adjusting the classifier, the thickness required for different products can be achieved. 1. Steel slag is used in cement production. Steel slag is a material containing silicate and iron aluminate mineral phase calcined at high temperature. It has similar chemical composition to cement clinker and has hydraulic activity, so it has gelling properties. Waste slag should partially replace or completely replace Portland cement, which is expensive to manufacture and expensive. China's research on steel slag cement is at the international leading level. The steel slag cements currently produced mainly include steel slag slag cement, steel slag slag Portland cement, steel slag zeolite cement and steel slag ordinary cement. The production of steel slag cement generally follows the following process: 2. The physical and mechanical properties of steel slag used in road engineering steel slag depends on the treatment process. Generally, the steel slag with slow cooling treatment has large specific gravity, high hardness, anti-wear and low water absorption. It is a good aggregate for road construction and is stored for one year. The above steel slag, due to partial decomposition, the grading of the mixed steel slag is close to the asphalt concrete aggregate grading requirements. The mixed steel slag is directly used as the asphalt concrete aggregate, and the batching operation is convenient and simple. The steel slag is used as a road foundation, and not only can the steel slag be used in a large amount, but also a large amount of ground steel slag can be saved. 3. Steel slag is used in agricultural steel slag containing a large amount of calcium oxide and magnesium oxide, which can be used to improve acidic soil. Other trace elements can also increase the yield of crops. Especially if the content of P205 is above 5%, it can be used as phosphate fertilizer. There is no exact and scientific conclusion on the application research of steel slag in agriculture. The experimental research on soil type and crop species representative surface is not enough, especially the effect of steel slag fertilizer on soil structure after large application, and the trace element in steel slag Fruit transfer, fertilizer aftereffect and adaptability to soil also require long-term experimental observation, and experience is accumulated to promote the application according to local conditions. Steel slag is used as smelting flux converter slag and flat furnace slag with high calcium oxide content. It also contains manganese oxide and iron oxide. It can not only replace limestone, but also recover useful metals. For example, steel slag is used as solvent for sintering. Steel slag has vertical grinding. The following advantages: A. It can improve the gas transport property of the material layer, accelerate the vertical sintering speed, and achieve the purpose of strengthening sintering; B. It can improve production efficiency, reduce energy consumption, increase reduction rate, and reduce weathering rate: C. Reduce the cost of sintering. Practice has proved that steel slag is good for smelting flux and will not affect the quality of sinter and pig iron.

(1) In order to prevent the white hole from being generated during the Stainless steel casting, in addition to the measures taken in the process, the wall thickness must not be too thin (some materials indicate that when the wall thickness is 15 mm or more, the corner of the casting with metal type must be For rounding, the casting fillet of aluminum alloy and magnesium alloy metal castings should not be less than 3-4m. For casting cast iron, cast steel and copper alloy metal castings, see Table 1.1-32; (2) Due to the metal type and core non-consistency, in order to facilitate the removal of castings and extraction type, the casting inclination of stainless steel castings should be larger than that of sand castings, generally 30%-50%, it should be noted that: casting In addition to the type of alloy and the height of the wall, the degree of slope is also related to the position of the surface of the casting. Any surface of the casting that has a tendency to detach from the surface of the metal when the casting is cooled and contracted can be designed with a small slope and shrink in the casting. The surface of the casting that tends to be pressed against the metal mold should be given a large inclination, and the casting inclination of the stainless steel casting of various alloys; (3) Due to the rapid heat dissipation of the metal type, the minimum wall thickness of the Stainless steel casting should be larger than that of the sand casting casting, and the minimum wall thickness of various casting alloys and castings of different sizes; (4) The thickness of the inner wall and inner rib of the stainless steel casting casting should generally be 0.6-0.7 of the thickness of the connected outer wall. Otherwise, since the inner wall (rib) is cold, the crack is likely to occur at the intersection of the inner and outer walls when the casting shrinks.

What are the methods for adjusting the output of jaw crusher? First of all, we must ensure that the power supply voltage of the crusher production process is stable and the production has a good condition; the wiring position of the jaw crusher motor is reversed, which affects the work of the motor. The size of the discharge port of the jaw crusher is small, and the production output is reduced, and the discharge port is blocked. Therefore, it is necessary to increase the size of the discharge opening; the displacement of the jaw of the jaw crusher will also affect the equipment. Working condition and work efficiency, to ensure the position of the seesaw is suitable; after the use of the jaw crusher for a period of time, the jaw structure and the bearing wear increase the working gap, the bearing rotates relative to the outer ring, so that the output is reduced, and the seesaw can be checked frequently. And the wear condition of the bearing and replace it in time. When the output of the jaw crusher in Shanghai SBM Heavy Industry declines, it is necessary to find the key to the problem according to the possible failure, find the problem in time and solve the problem, and ensure that the equipment can operate efficiently. The crusher manufacturer SBM Heavy Industry, declined to reprint! What are the accessories that affect the production of crushers in Shanghai? What are the accessories that affect the production of crushers in Shanghai? When it comes to the production efficiency of crushers, it is not difficult to think of the wearing parts of crushing equipment. It can also be said that it is accessories or parts. Shanghai SBM Heavy Industry Crusher manufacturers give customers a simple analysis. First, the high-speed transformation of the hammer causes a sharp impact between the material and the hammer and the screen and the tooth plate, which is called crushing of the material. In the process of severe impact, the hammer will gradually wear under the impact of the front of the material, and the impact effect and the crushing effect will be greatly reduced, resulting in a decrease in work efficiency. Secondly, the bearing is an important part for fixing and reducing the friction coefficient during the working process. Because the machine not only increases the energy consumption of the metal crusher but also easily damages the bearing when the machine is running at high speed, Shanghai SBM Heavy Industry adopts pre-lubricated bearings, which is The bearing has its own lubricant. Professional manufacturer of crusher, Shanghai crusher, Yunnan crusher, please look for SBM Heavy Industry!

When the Raymond mill is aging, it is necessary to take appropriate remedial measures. If the problem is serious, the equipment needs to be replaced. In the actual production process, there are many ways to delay the aging phenomenon of the Raymond mill. Then, how do users carry out maintenance work on the equipment and delay the aging of the equipment? First, choose the right lubricant, the oil should be moderate, the long-term lubrication of the equipment will not cause the equipment to wear seriously, and this is also an important cause of equipment aging. If the lubrication is not good, it will greatly increase the wear level of the equipment. Reduce equipment usage time. During the use of Raymond mill, the lubricating oil should be lubricated with the correct lubricating oil to avoid contamination of the lubricating oil. The amount of lubricating oil should be moderate. Do not add too much oil. Second, do a good job of equipment maintenance, parts that are severely worn need to be replaced in time, in the use of Raymond mill, should carefully observe the use of various parts of the equipment, especially the use of wearing parts, in a timely manner Check the records and record the number of inspections for each component, and repair some of the worn parts in time and replace if necessary. Third, preheating before starting in winter, lubrication in summer, cold weather in winter, low temperature, easy to freeze oil, so when using Raymond mill, you need to carry out preheating for a few minutes of empty operation to avoid equipment running. Failure, downtime, etc. The temperature in summer is high. Under high temperature operation, the temperature of the equipment is relatively high, which is easy to cause damage to parts. Therefore, the lubrication of the equipment must be done well to reduce the heat generated by friction.

1, material properties. It is related to the hardness, properties and composition of the material. Hard materials can easily cause wear of the fine jaw crusher, and some materials can cause corrosion and blockage of the fine jaw crusher. 2. Structural design. Reasonable structural design can effectively reduce the wear of the fine jaw crusher and vice versa. 3, materials. The correct choice of the material of the fine jaw crusher will affect the loss of the equipment. 4. Operational use. Even the finer and more wear-resistant materials of a fine jaw crusher will not last long if handled and used improperly. Generally, the crystal grains are fine and uniform, and the carbides are spherical and uniformly distributed, which are favorable for improving the rolling fatigue life. After processing the bearing steel, the more retained austenite, the coarser the needle-shaped martensite, the lower the residual compressive stress and the strength of the carburized layer, and the greater the possibility of microcracking. Under the same undissolved carbide state, when the mass fraction of carbon in the martensite is about 0.4% to 0.5%, the strength and toughness of the material are better matched, and the contact fatigue life is high. For undissolved carbides, it tends to be small, small and uniform by appropriate heat treatment, avoiding the occurrence of coarse or banded carbides, and is advantageous for eliminating fatigue cracks. As the hardness increases within a certain range, the contact fatigue strength will increase. In addition, the hardness matching of the two contact rolling elements is also important. Factors affecting the wear of parts of a full hydraulic cone crusher: 1. The structure and quality of the part. The higher the casting quality of the full hydraulic cone crusher itself, the more stable the work and the less prone to wear; 2. The physical and mechanical properties of the broken ore. The harder the material of the full hydraulic cone crusher is, the more likely it is that the equipment parts will wear out; 3. The material of the part. The worse the casting material of the full hydraulic cone crusher, the easier it is to wear; 4. Installation quality. The less stringent the installation, the worse the performance of the full hydraulic cone crusher and the easier the wear. 5. Use and maintain quality. Use according to the operating manual without regular maintenance to reduce component wear.
