Vertical roller mill treatment of steel slag has a significant effect

Publié le 25/04/2019, par sbmcrusher,
At present, China's steel slag has a large amount of emissions and low utilization rate. The use of steel slag as a pavement base material can greatly reduce the exploitation of natural earth and stone materials, and has significant economic and social benefits. The graded steel slag and gravel are blended in a certain proportion to form a composite aggregate, which not only optimizes the grading of the steel slag, but also reduces the adverse effect of the hydration expansion of the steel slag on the stability of the aggregate body-level distribution. The composite aggregates were stabilized by different binders, and the ratio of the unconfined compressive strength was optimized. The ratio of the fly ash was directly stabilized and the cement fly ash was stabilized.

As a new type of crushing equipment, the Construction Waste Crusher has been purchased and used by more and more people, and has become the choice of large and medium-sized enterprises and even individual households. In the current majority of users are only concerned with production and use, paying less attention to the cleaning of the equipment, sometimes inevitable problems in the production process, so that the user is in a passive state, so that the crusher can not continue to invest produce. First, before we prepare to use and start up, we must first check whether the components inside the fuselage are firmly installed, whether there is looseness, and there is no oil stain on the belt and the pulley. It should be wiped clean with a clean rag in time, do not leave stains. And dust. Whether there is any residue material in the feed port and the discharge port, it is necessary to timely process to ensure the discharge port and the feed port are clean and tidy. At the same time, it is necessary to see if there are any other debris in the crushing chamber of the equipment, and also clean it up in time. For the specially designed metal crusher, there is a lining plate placed in the crushing cavity. At the same time as the rotary cutter is selected, the metal material will grind some paint on the lining. We must also ensure that there is no impurity or paint house inside. Only in the early stage, we have done these cleaning work, so as to ensure that the equipment will not appear in the use of other materials should not appear in the use, so as not to affect your production and use, but also make the Quarry crusher life longer. For a long time, bring you more convenience. When cleaning the crusher, the first thing to pay attention to is the safety problem. You must disconnect the power supply before you can clean it. Then open the inside of the crushing chamber, clear the remaining material, and then clean the residual material on the hammer. When cleaning, use a cleaning tool such as a brush or a towel to avoid injury. After cleaning the material, clean it with 75% ethanol and then close the crushing chamber. At this point, the interior has been cleaned, the rest is to clean the appearance of the crusher, the ground is also to be cleaned. After this is done, then boot up and see if there are any errors.

Gypsum mill has become an indispensable milling equipment in mine production

Publié le 23/04/2019, par sbmcrusher,
Gypsum mill can also be called Raymond Mill, the full name of English: Raymond mill, is a kind of grinding equipment from abroad. After decades of continuous improvement and innovation, the domestic gypsum mill has already possessed a high level abroad, and has become an indispensable milling equipment in mine production. It is widely used in metallurgy, building materials, chemicals, cement, roads. Construction and many other areas. The utility model has the advantages of high production efficiency, convenient use and maintenance, good finished product granularity, long service life and high automation degree. As a mechanical device, it is the fundamental function of the device to maximize the release function and increase economic efficiency. The entire life of the equipment is doing work, which is the same as the material formula, and has a lot to do with working hours. Finding ways to increase the working life of the Raymond mill and increase the use time will naturally increase the economic benefits. Here, we must talk about the importance of scientific management of machinery and equipment. At the moment when the equipment is in the hands of the manufacturer and the user, the user needs to be maintained. The scientific and reasonable maintenance method can make the machine run stably. Today, we will give the following suggestions for the maintenance of the gypsum mill and the extension of its service life. The working environment of the gypsum mill should try not to leak the work, it is best to re-indoor, so as to reduce the damage of external factors to the equipment, the equipment without wind and sun must be more durable. The strong fortress is broken from the inside. Although Raymond Mills' idea is to try to increase the compressive and impact strength of Raymond Mill, it is necessary to maintain the necessary maintenance methods. Since Raymond Mill is a grinding equipment, there will be residual powder materials inside after a period of inactivity. The grinding chamber should be cleaned regularly to ensure smooth powder discharge. For a period of time, the gypsum mill needs to add lubricant regularly. The links inside need regular lubrication. They must be well lubricated to work properly. If you find that the parts are worn out, you must replace them in time. Just like people, the loose teeth should be treated in time, otherwise it will affect the mouth and affect the whole body. The same is true for the gypsum mill. Timely treatment can guarantee the quality and output of the product, and it will greatly help the life of the equipment.

Five control methods for vertical roller mill feeding amount

Publié le 22/04/2019, par sbmcrusher,
The amount of feed in the Vertical Roller Mill grinding process has a great influence on the vertical grinding index. It is the main control quantity used by most non-ferrous metal vertical roller mills to control the vertical grinding process. Adjusting the amount of vertical grinding operation can capture more useful metals and suppress unwanted minerals, which are two important ways to ensure the vertical grinding index. This article describes the five vertical abrasive dosage control methods. (1) Vertical grinding micro-feeder The microcomputer feeding machine controls the on-off time of the solenoid valve to achieve timing and quantitative feeding of multiple feeding points, and displays relevant parameters of each feeding point on the CRT screen, thereby improving the feeding control. According to the change of each process parameter in the feeding process, each set value can be modified in time. (2) Controlling the amount of vertical roller mill feed according to the proportion of ore to mine These are two simple controls. The computer converts the flow rate and concentration signal of the ore slurry into the dry ore quantity of the ore. According to the dry ore amount and the predetermined ratio, the required material dose is calculated as the given value of the flow regulator, adjusted by the regulator, and then distributed. The material is distributed to the feeding points of each vertical grinding tank group, and the advancement of the vertical grinding fittings is fully utilized. It should be noted that with this control method, the concentration of the material should be kept constant, and the liquid level of the storage tank and the pressure of the material circulation loop need to be kept constant. (3) Control the amount of vertical roller mill feed according to the proportion of metal in the ore The feed ratio can be given manually or according to the original grade, in a two-determined relationship. (4) Control the amount of vertical roller mill feed according to the amount of metal in the ore and the grade of tailings The feature of this method is that the tailing grade that reflects the vertical grinding effect can be corrected. (5) Control the amount of vertical roller mill feed according to recovery rate and concentrate grade The useful mineral content in the tailings can reflect the effect of the vertical grinding operation to a certain extent, but when the mineral properties change, it does not guarantee that the vertical grinding process reaches a predetermined index. Therefore, the recovery rate and concentrate grade need to be used in two steps to control the dosage. The current-carrying ray analyzer sends the grade signal of the metal in the original, fine and tailings to the process control computer. The computer first calculates the new recovery rate based on the original ore grade, and then calculates the actual vertical recovery rate based on the calculated actual recovery rate. The amount of material added.

Sand making machine operation attention detail to increase efficiency

Publié le 20/04/2019, par sbmcrusher,

For the customers, the sand making machine equipment that they hope to buy can always be produced efficiently, but any equipment is not idealized. We have talked about some ways to use the sand making machine efficiently to improve efficiency. Let's talk about the correct use of the sand making machine to reduce power consumption, so as to improve the service life of the equipment. First of all, we should understand a problem, the new sand making machine is the third process of the entire sandstone production line, one is feeding, the second is the rough breaking of the jaw crusher, and the third is the new sand making machine. The new sand making machine is used as a rough breaking equipment in the crushing of hard materials such as ore. It has the characteristics of large crushing ratio, high output, uniform particle size, simple structure, convenient maintenance and low production cost. When the new sand making machine works, the moving jaws are in direct contact with the materials, and thus the load is often large. There are insurance pieces to provide protection for this situation, which will greatly improve the active control ability of all sand making equipment and production lines. Secondly, we should understand that the more mud or fine grain in the feed of the gravel production line, the greater the viscosity of the slurry, the smaller the sedimentation velocity of the ore in the slurry, and the coarser the particle size of the overflow product; In case, in order to ensure the desired overflow fineness, the additional water can be appropriately increased to reduce the slurry concentration. If the amount of mud in the feed is small, or after de-sludge treatment, the concentration of the slurry should be appropriately increased to reduce the amount of fine-grained materials entrained in the return sand. When the new sand making machine enters the non-crushing stone in the crushing chamber, the rear thrust plate is taken as the safety component of the sand making machine to protect the important parts of the equipment from damage. The back thrust plates are individually cast from cast iron, and a slot or holes are opened therein to reduce the strength of the section; or two pieces can be cast, and then screwed together to form a combined thrust plate. However, when the stone that cannot be crushed and sand enters the fine crushing cavity, the equipment generates an overload scene, and the thrust plate is transmitted to the thrust plate to cause the thrust plate to be broken or the screw of the combined thrust plate to be cut, and the machine ends the work to play an insurance role. This design principle is not only very suitable, but also easy to hold, the use of insurance parts is cheap, easy to operate, and the overall maintenance and damage of the equipment is also very good. The new sand making machine has fine grain requirements for sand making materials. In general, the needle-like material enters the finely divided nacelle, and the requirements for the crushed stone are contrary to the above, and the requirements for the grain type and the grain size are very strict. The reason is that the cubic sand has a function of locking each other due to its angular shape, and the continuous grading of the sand can greatly reduce the void, while the cubic sand occupies a larger surface area than the circular sand. Sticking asphalt and materials or cement and materials together reduces the possibility of displacement. In this respect, users may feel that the loss of the new sand making machine seems to be more difficult than improving production efficiency, but it is not. This is just a matter of literal understanding. As long as we usually produce and observe more research, we will understand that the new sand making machine is a sand making device with a very simple working principle. It is simpler and more efficient than traditional equipment. More to bring benefits to customers. If you have any technical questions, please feel free to call our company's sanding equipment sales department. Our company will provide you with a professional answer free of charge.
