In industrial production, the quality of its Raymond mill is the most critical. At the same time, most of the reasons that affect the production efficiency of the equipment during the production process are the performance of the Raymond mill. So, what should users pay attention to when producing Raymond mill?

First of all, Raymond mills are widely used in various industries, so that their production efficiency has attracted the attention of many users. As a manufacturer, in the production process, more attention should be paid to ensure that production is guaranteed. At the same time, equipment performance is important for a project. If the production cannot be completed in use, the equipment is not suitable.

Secondly, when the user purchases the appropriate equipment, there are many problems in the production, indicating that the equipment is not properly used, so that its performance is not fully exerted, resulting in the entire project can not be carried out. For the use of Raymond mills, proper operation and maintenance are required to achieve good performance.

Once again, when using the Raymond mill, pay attention to the cooperation of the parts and components, and there will be no problems during production. At the same time, in order to extend the service life and effect of the equipment, the user needs to do the corresponding lubrication work, which improves the production efficiency to a certain extent and provides assistance to the user.

Then, in operation, in order to produce efficiency and production efficiency, it is necessary to pay attention to the uniformity of the feed during production, and it is not possible to dope other impurities, especially hard impurities, thereby damaging the use of the equipment. At the same time, attention should be paid to the vibration of the equipment. During production, a large amount of vibration will occur, and corresponding measures need to be taken to improve this phenomenon. When the Raymond mill is out of the material, if it cannot be discharged normally, it will malfunction and should be repaired.

The casting process of Raymond Mill equipment is an important factor to determine the quality of wear-resisting parts. Today, Shanghai SBM Heavy Industry Co., Ltd. Introduces three factors that affect the casting process of Raymond mill.

1. The quality of raw materials used in casting directly determines the quality of Raymond mill. For example, the quality of refractory materials, fuel, flux and casting sand is not up to standard, so that defects such as pinhole, slag inclusion and sand sticking occur in cast iron, which will affect the quality of cast iron and make cast iron scrap.

2. Reasonable process operation rules to improve the technical level of workers. In production, the quality of Raymond Mill castings should be controlled. At the same time, from raw materials, auxiliary materials to each product control and inspection process. For each process must be strictly in accordance with the process code, and finally the quality of the finished castings are inspected. Good materials, coupled with reasonable process operation, can produce high-quality products.

3. According to the structure of casting parts, the quality and size of wear-resisting parts, the characteristics of casting alloy and the production conditions, the proper casting process should be selected and the casting ribs, gating system and risers should be reasonably set up to ensure the good cast iron parts.

Above are three factors about the casting technology of Raymond mill. In production, the problem of abrasion is unavoidable. Good raw materials, reasonable operation rules and casting technology are needed to improve the quality of abrasion-resistant parts of Raymond mill.

As is well known to the public, the rotation of the Raymond mill is mainly driven by gears. If the gears are not in good condition, the Raymond mill does not work under normal conditions. Therefore, it is necessary to understand the transmission characteristics of the gears of Raymond Mill.

The transmission characteristics of the gears of the Raymond mill are at the following six points:

1: Widely used, a wide range of transmission power and speed. The instrument gear has a minimum diameter of less than 1 mm and a heavy gear has a diameter of more than 10 m. The power transmitted through the gear can be 100,000 kW, the peripheral speed is 300 m/s, and the speed is 10,000 rpm.

2: Accurate transmission ratio, stable operation, accurate and reliable transmission activities.

3: High transmission efficiency, generally 0.94-0.99; small wear and rear, long service life.

4: Compact structure, large realizing transmission rate. In general, the gear ratio of the circular gear is 5-8, and the combination of various shifting and commutation can be realized.

5: Gear manufacturing and installation accuracy requirements are high. The gears should be processed and specialized equipment manufactured by sophisticated technical methods as a costly result.

6: The distance between the transmission axis to be used and the center is large, which is not applicable.

The same as the grinding equipment, from the name alone, raymond mill and ball mill have a big difference. In addition, Raymond mill and ball mill are also very different in appearance. For example, the ball mill is made up of horizontal cylinders, feeding and discharging. The hollow shaft and the grinding head are composed of a part, the cylinder is a long cylinder, and the cylinder is provided with an abrasive body. Raymond Mill is built. What other differences are there between Raymond mills and ball mills? From the function point of view, the difference between Raymond mill and ball mill is that the powder of Raymond mill is much finer than that of the ball mill. The difference in fineness between the two mills is large, the discharge speed of the ball mill is fast, and the material after crushing The particle size is relatively coarse; after years of improvement, Raymond mill has a grinding fineness of 325 mesh for mineral raw materials. In addition, Raymond mill is mainly used for ultra-fine pulverization processing of various ores, building materials and chemical materials with Mohs hardness below 9.3 and humidity less than 6%, such as graphite, talc and kaolin. Fine powder processing of stone, limestone and other materials, the fineness of the finished product is as high as 2000 mesh, which is suitable for projects and projects with high requirements on fineness of some materials. Ball mill is mainly used for materials with Mohs hardness below 7 and humidity below 6%. It is widely used in black and non-ferrous metal processing, fertilizer processing, refractory processing and silicide manufacturing. It can dry and wet materials. Grinding, the fineness of the finished product can reach 425 mesh, which is commonly used in the beneficiation production line for the grinding of materials, preparing for the next process of the production line. Raymond mills and ball mills have their own advantages, each with its own characteristics, so the majority of users must choose the right mill equipment according to their own needs when purchasing the mill.

Raymond Milling Equipment is the most commonly used in the milling industry. There are various problems encountered in the course of their work. Some users have asked us that the material fineness of the raymond mill has not reached the standard. Due to the grinding equipment manufacturers, Shisheng customers often ask about the difference in the fineness of the milling, sometimes. Some of these new customers are particularly familiar with the use of technology.

Shi Sheng suggested that if you encounter such a problem, take a look at the following method (the technical parameters of Raymond Milling Equipment, generally based on limestone):

A. Reasons for grinding materials: the purity of abrasive materials of different materials is different;

B. Effect of feed rate:

1: too much feed

2: Insufficient feed

3: Effect of feed size

Fan flow 4: size, larger air volume, coarser, and, conversely, smaller grain size.

Specifically, if the hardness of the material is large, the fineness of the material will be greater. Operated. Users of Raymond Milling Equipment know that when it is in operation, if too much feed will cause blockage of the throttle, blockage of the throttle will result in a drop in production. If the feed is too small, the wind will be too large and the particle size will be large, so it is best to know the fineness of the feed. Another reason is the adjustment of the fan, resulting in a large particle size meeting, the fan's air volume, but the size is good. Therefore, if the grain size of the Raymond grinding equipment is not standard, it can be adjusted by the fan.

Due to the long working time of Raymond mill, it brings people benefits and continuous loss. Therefore, when using the equipment daily, we should pay attention to the maintenance of the equipment. In addition to some maintenance, some parts that cannot be touched are needed. These have played a key role in the normal operation of the Raymond mill. Then, how to properly maintain the wearing parts of Raymond Mill.

1. The blade of Raymond Mill mainly shovels the material between the grinding roller and the grinding ring, so that the material is fully crushed. When the blade continuously shovels the material, the materials of different quality and hardness are used for a long time. The contact friction is easy to be worn. In severe cases, the blade will not be able to shovel the material, which will affect the working efficiency of the Raymond mill.

Second, the grinding roller and the grinding ring are the wearing parts in the whole equipment. In the production process of the Raymond mill, the material passes directly between the grinding roller and the grinding ring, so that it is squeezed and rotated by the two to achieve fine crushing. Effect. Because the grinding roller and the grinding ring are constantly subjected to the friction of the material, and are subjected to frictional forces between each other. When the grinding roller and the grinding ring are severely worn, or when the wear is uneven, it will have a certain influence on the fine powder production, and thus the unevenness of the fineness of the finished product may occur.

Third, Raymond mill's blade, grinding roller and grinding ring play a very important role in the production, and in the entire crushing process, play an irreplaceable role, so this is the easiest Raymond mill The worn parts. Remind users that during the production process, it is recommended to check the degree of wear of the blade, grinding ring and grinding roller frequently, and maintain the wearing parts reasonably to extend the service life.

The above is about the maintenance of the wearing parts of Raymond Mill, I hope to help everyone.

Everyone should be very clear. A complete set of Raymond mill system consists of three parts: the main machine, the analysis machine and the fan. In the Raymond mill control system, you need to pay attention to the situation of these three motors, so that you can work on the equipment grinding work. To understanding. Recently, some customers have called to consult, what is the reason for the high current of the Raymond mill fan? This kind of problem can not be considered from one side, and should be combined with the entire Raymond mill system for investigation.

First, check whether the lower air duct is blocked. After passing the qualified fine powder of the analysis machine, it is necessary to go through the pipeline, enter the powder collector, and finally obtain the finished product. When the machine is turned on and off, the fine powder will precipitate due to the absence of wind. Therefore, during normal operation, a small amount of fine powder will be deposited through the curve. After a long time, the fine powder of the air duct will accumulate. Especially in the corner part, it is easy to cause the phenomenon of blockage. At this time, the fan will generate heat, and the current of the fan motor will rise. It requires a timely volume, and it is necessary to check whether the air passage is excessively fine. The corresponding solution.

Secondly, the Raymond mill feeds fast, which also causes the feed to block the material. At this time, the blockage will cause circulating wind in the main engine and the pipe. On the one hand, the function of the grinding roller and the grinding ring in the main machine is seriously consumed. If the wind does not go up, it will cause the fan current to rise, and it needs to be stopped for inspection.

Finally, check whether the fan belt of the Raymond mill is loose. At the same time, the driving mode of the fan is that the motor is driven by the belt. When the belt feeds, the wind will be insufficient. If there is not enough air volume, the material is difficult to be blown up. It will also rise, and more attention is needed at this time. If not handled, it will affect the output of the equipment.

The above is a brief introduction to the high current of the Raymond mill fan. If you want to know more about this, you can do detailed consultation online.

As the most common milling equipment at present, Raymond Mill plays an important role in the processing and production of various materials. During the operation of the equipment, if the operation is not proper, the fan current will rise, which has a great impact on the production operation of the equipment. Therefore, here we will analyze the cause of the increase in the current of the Raymond mill fan.

First, the wind channel blocking material

In the production of Raymond mill, the qualified materials are separated by the analysis machine, and the finished product is obtained by entering the powder collector through the pipeline. As the working time of the equipment is prolonged, a small amount of fine powder is continuously deposited from the bend of the pipeline, and the long-term flow will lead to the accumulation of fine powder in the air passage, especially in the curved portion. This phenomenon, the fan will heat up, the current rises. Therefore, when the fan current of the Raymond mill is increased, it is necessary to stop the inspection and clean it in time.

Second, the feed is too fast

When the user feeds the Raymond mill too fast, or the feed amount is too much, the material will not be fully ground, resulting in blockage of the grinding cavity, resulting in no circulation in the main body and the pipe, thus increasing the number of The wear efficiency of the grinding ring increases the current of the fan of the equipment. Therefore, it is necessary to maintain a uniform and orderly feed to prevent the fan current from rising.

Third, the wind is insufficient

The fan is an important part of the Raymond mill, and the wind power of the fan is the key factor to ensure the smooth operation of the equipment. Therefore, if the fan current of the Raymond mill is insufficient and the material cannot be blown up, the fan power will be too high.

The above three points are the reasons for the increase of the current of the fan of the Raymond mill. In daily production, the user should carefully observe the use of the equipment. Once the problem is found, the machine should be shut down in time to eliminate all faults before restarting.
