Vertical mill is widely used in the production of vertical roller mill powders required by mining, construction, chemical, cement and other industries. Some industries are produced indoors, but some industries need to be outdoors when it is produced.
In winter, the production of the machine will be hindered, so in the winter, we must pay attention to changing the maintenance measures of the vertical roller mill. So what is the difference between this season’s maintenance measures and other seasons
Let me introduce the place where the vertical roller mill maintenance is the same all the year to prevent the entry of foreign objects. For the damage of the accessories, pay attention to the maintenance when normal, the lubricant should be added in time, check regularly to see if the screws are loose, and choose to meet The materials required by the machine, etc., are all designed to extend the life and prevent damage to the ultrafine grinding equipment.
The grinding roller is a component directly involved in the ore crushing work in the process of Raymond grinding production. Because of the strong friction and impact with the hard ore, the grinding roller is extremely vulnerable to damage during the production process.
It is difficult to work properly if the equipment is replaced, and the replacement of the grinding roller of the Raymond mill equipment will increase the operating cost of the equipment.
Fundamentally to prevent wear and tear, this mainly refers to the production material of the grinding roller. If high-quality steel is used to produce the roller component, its strength can be increased, so that it can reduce the impact with the material during production.
The maintenance of the stone crushing plant is the work that the user has to do every day, so that the stone crushing plant will not be in use and there will be big problems. Moreover, the maintenance work should be adhered to. After each stop, check whether the bolts of the various parts of the stone crushing plant are loose. If it is loose, it should be firm. Check the amount of lubricating oil in the bearing chambers before and after the main engine, and refill the bearings on time. Inject lithium-based lubricant into the end cap nozzle.
Of course, when lubricating, it is necessary to prepare, which is related to the quality of lubrication. Therefore, first check the lubrication condition of the bearing chambers of the front and rear of the main engine, such as grease deposits, must be cleaned; to update the grease, see its bearing wear condition, see if it needs to be replaced.
In addition, check the bolts on the outside of the ultra-fine mill and ask for their robustness. To open the main stone crushing plant, check the wear condition of the hammer, if it is necessary to update the new parts; check the fan blade connecting bolts, whether there is looseness, whether the leaves are worn seriously, if it is loose, it should be strong or replaced; check the lining plates of the crushing parts and Whether the body fixing bolts are loose or not, the looseness is to be strong, and the lining plate is seriously worn to replace the new parts; check the inside of the burning furnace to remove the scale and repair the lining.
The mill is the ideal equipment for today’s stone papermaking, coating grinding and other ores, non-ore crushing, especially advanced production machinery such as Raymond mill , which has a good performance in the process of processing materials. Like theRaymond mill, its analyzer uses high-density blades to improve the fineness of the powder and the output. It has been proved that increasing the blade density can improve the fineness of the finished product under the condition of constant rotation speed.
In the upgraded mill, the same resistance arrangement is adopted, which avoids the difference between the two powder collectors, thereby improving the powder collecting efficiency of the dust collector, reducing the internal circulation and further increasing the output of the mill. It is the charm of production.
However, there are many companies in China’s mills, which provide a lot of choices for users’ needs, but at the same time cause a lot of troubles. Because of the technical differences and the differences in hardware, the quality of each manufacturer is different, and there will be shoddy purchases due to the pursuit of excessive benefits, so the reputation of the manufacturers is greatly damaged.
Ultrafine grinding of cement plays an important role in the production process of cement, but the price of equipment is a very important factor when customers purchase. How many is the price of cement mill.
The difference in the type of equipment leads to the difference in price, and the difference in the manufacturer of the equipment will also affect the price of the equipment, because the manpower and material resources invested by different manufacturers in the production process of the equipment are different, and even the after-sales of the equipment is not The same, so the price is naturally different.
The reason why the price of cement ultrafine grinding is different is that the model of the equipment and the manufacturer of the equipment will affect the price of the equipment. Different manufacturers have different quotations for the ultrafine grinding of cement, and the same manufacturer has different types of equipment.
Superfine grinding requires a good cooperation of the various components in order to quickly complete the pulverization of the materials, so the quality of the parts and the collocation between them are very important.
In addition to ensuring the correct installation position of each part of the dolomite powder milling machinery, pay attention to the inner hole of the grinding roller. Because it has certain rules and the size is also certain, pay attention to the size of the inner hole when matching. The size of the grinding roller shaft must be matched, otherwise it will cause waste of the fitting, which will increase the production cost and is not conducive to the final production profit.
There are two main points to note when super-fine grinding parts are used. First, the order of installation of each part is correct. Second, the size of the inner hole and the size of the grinding roller shaft must match. Otherwise, the equipment will not operate normally. Or it is a waste of accessories, no matter which kind of phenomenon will lead to impaired production efficiency.
Promoting the development of small and medium-sized slag mill processing plant enterprises has become the focus of the domestic slag mill processing plant industry. Then, how can we achieve the rapid development of small and medium-sized slag mill processing plant enterprises? This requires outside support and requires the efforts of themselves.
First of all, the government should encourage the development of small and medium-sized private enterprises, increase support, and give more preferential measures in terms of policies. At the same time, provide more support in terms of technology and funding.
Secondly, domestic large-scale slag mill processing plant enterprises must also provide certain assistance to the development of small and medium-sized enterprises, and promote the development of small and medium-sized enterprises through technical exchanges and cooperation.
Finally, while themselves actively introduce foreign technologies and concepts, they must intensify their efforts in technological innovation, increase investment in scientific research, change their development methods, and market-oriented, and explore a sustainable development path that suits them as soon as possible. .
The jaw crusher is a bite-shaped bite that can break even materials. When the displacement between the jaws occurs, the movement should be adjusted to continue the use.
Before using the jaw crusher, be sure to read the manual first. When selecting the material, you must select the crushing standard to understand the maximum hardness of the crushed material that can be crushed by the jaw crusher to select the appropriate machine to avoid the above phenomenon.
From the site inspection of the crusher to the selection of equipment, to the installation and commissioning, to the final production acceptance, provide the overall solution, and dispatch the technical team to train the relevant operators to help customers maximize the value in the short term.
In order to reduce the failure of the marble grinding machine in the production process, the newly purchased equipment will be tested after the installation, so that the equipment itself and the installation process may be faulty. This is the purpose of the test operation. Let me introduce what the correct operation of the test run is.
The first is the no-load operation. When the material is not added, run the marble grinding machine machine. Then observe whether the screws and other parts are loose, the wire connection is normal, and the wire needs to be protected from being pressed. Otherwise It will cause line problems. It is also necessary to pay attention to the presence of noise and other abnormalities. If not, the no-load operation takes 2 to 4 hours, so that the possible faults can be fully observed. During the operation, pay attention to whether the bearings of the marble grinding machine are Will be hot, etc., these will be carried out without problems after the load;
The second is the inspection of the marble grinding machine on-load operation. It is to add materials to the equipment and then make it run. In this process, besides paying attention to whether the screws, rotors, etc. are loose, pay attention to the order of starting the machine to prevent improper start-up. The damage caused by the test machine is usually 8 to 12 hours. The problem to be paid during the operation is whether the bearing and other components have faults. The sequence of the shutdown after the end of the operation cannot be wrong.
In addition to the above factors, there are still many factors affecting the vertical mill output. For example, the mixture structure leads to material segregation, air volume control, hot air temperature control, batching control, etc., which will affect the vertical mill output. In actual production, it should be analyzed according to the specific conditions of the factory.
After the material is fed into the grinding disc, a certain layer is formed. When the thickness of the layer reaches a certain thickness, the grinding roller starts to grind. If the material layer is too thin, the grinding stress is too concentrated, and the grinding ability is reduced, which will inevitably lead to impact of the grinding roller liner and the grinding disc liner.
The grinding machine has large vibration, easy to jump, and will damage the liner, the tension rod, etc. Can not be controlled by thin layer. If the thickness of the material layer is too thick, the grinding force will be converted into lateral stress, and the sliding shear will be formed between the materials. The slump of the material bed will increase, the milling efficiency will decrease, and the vibration will be large.
The material will not be timely. Grinding and extruding the grinding disc, falling to the spout ring, increasing the circulation amount, the pressure difference is large, the material can not be ground away in time, forming a vicious circle, which can only reduce the production operation and affect the mill output.
The thickness of the layer is generally controlled to be about 50-80 mm. The principle is that the material fed into the mill should be ground in time and flow to the next process in time. The pressure difference of the system should not be too high to ensure that the vibration is within a reasonable range.
