Raymond Mill startup difficulties

Sometimes, with the prolonged use of Raymond Mills, Raymond Mills have started longer and longer. What is going on? Here, Great Wall Heavy Industries’ raymond mill experts advise you on some diseases that are difficult to start with a flour mill.
1, Raymond Mill power. If the power of the Raymond Mill is relatively small and does not reach the rated power, Raymond Mill equipment cannot start up.
2, Raymond Mill’s maximum bearing capacity. If it is difficult to start the Raymond Mill, you should look at the maximum load capacity of the mill in the manual of the mill. When the Raymond Mill is overloaded or it encounters too many steel forgings, it will be particularly difficult to start. .
3, Raymond mill loading. It can also be difficult to start when the Raymond mill is underloaded.
Therefore, do not attribute the difficulty of Raymond Mill startup to the quality of the product. If you suspect the credibility of the mill’s products, we should start with ourselves and check whether the Raymond Mill is guilty of the above. This kind of disease, or is it because of some mistakes in its operation, because the slow start of Raymond Mill is basically not directly related to the quality of Raymond Mill.

What are the dust removal equipments that are matched with the HGM ultrafine mill?

The development of science and technology and economy has basically met people’s production and living needs. However, although people’s material life and spiritual enjoyment have been temporarily satisfied, the increasingly harsh environment has seriously affected people’s normal lives. Many people still have Because of the harsh environment, I was afflicted with various diseases and eventually died. So now people are paying attention to how to protect our environment while developing their economy. In the milling industry, environmental protection work needs to be done more closely. The use of dust collectors allows dust mills to stop dancing during the production process.
Although the use of dust collectors has a good effect on the protection of the environment, some users did not configure the mill at the beginning of the purchase, or they were randomly deployed in later use, and did not completely match their own milling equipment. This will not be able to play an environmentally friendly role. This does not show on the website today that a customer has consulted where to sell the dust removal equipment for the HGM Ultrafine mill.
HGM Superfine Mill is the latest research and development of ultra-fine powder equipment in recent years, there are many manufacturers on the market are producing, but due to different design and technology, will also cause users to buy HGM Superfine Mill has a certain The difference. Shanghai SBM is a professional ore milling machine manufacturer. HGM Superfine Mill is currently a company’s main pusher of a milling equipment, and its supporting dust collector also has many models, including bag filter, pulse dust collector Etc., both have their own advantages, users can choose according to their actual needs.
In addition, Shanghai SBM also reminds its customers here that when choosing a milling machine, try to buy a complete set of machines, especially wearing parts, from one manufacturer, because the technology is rapidly developing, and it may not be long before you purchase. The manufacturer of that model will no longer produce this type of machine. It will be very troublesome if the wearing parts are broken.

How to extend the service life of the sand making machine

With the vigorous development of the construction industry, the increasing amount of sand for engineering use and the decrease in natural sand resources have made it difficult to meet market demand.

2. Check the rotation direction of the impeller and look from the direction of the inlet. The impeller should be rotated counterclockwise, otherwise the motor wiring should be adjusted.
3, the starting order of the sand making machine and the conveying equipment is: discharging → sand making machine → feeding; crusher is started with no load and can be fed after the crusher runs normally. The shutdown sequence is the reverse of the boot sequence.
4. Feeding granules strictly according to the stipulated requirements, it is forbidden to enter the crusher beyond the stipulated materials, otherwise, it will cause the imbalance of the impeller and excessive wear of the impeller, causing the plugging of the impeller passage and the center feeding pipe to make the crusher unable to work normally. Bulk material was found to be eliminated in time.
5. When the discharge equipment stops, feed should be stopped in time. Otherwise, the impeller will be crushed and the motor burned.
6. Feeding continuously and evenly.
7. During the operation of the crusher, there shall be no severe vibration and abnormal noise; otherwise, it shall be stopped and checked.
8, the lubrication of the machine is dry oil lubrication method, the amount of 1/2-2/3 of the bearing cavity, the crusher add a proper amount of grease for each shift.
9. In order to ensure the energy saving of the sand making machine, the tension of the driving triangle tape of the sand making machine should be adjusted properly to ensure the uniform force of the triangular tape. When the dual motors are driven, the two sides of the triangle tape should be grouped and matched. The group length is as consistent as possible. Stop the observation door at regular intervals to observe the internal wear condition of the sand making machine. The degree of wear of the center feed pipe, conical cap, impeller, down flow channel lining plate, circumferential guard plate and wear-resistant block should be promptly replaced or repaired after wear and replace. When grinding blocks should be replaced at the same time, to ensure the same weight of wear blocks. It is forbidden to open the observation door during the work of the crusher to observe the internal working conditions so as to avoid danger. It was found that the impeller body was worn out and promptly replaced by the manufacturer. The Sand making machine adds proper amount of grease every 400 hours of work, and works for 2000 hours to open the main shaft assembly to clean the bearing. Generally, it will work for 7200 hours and replace the new bearing. The upper bearing of the main shaft assembly is a floating end, and the lower end bearing is a fixed end.

Raymond Mill work process

After the bulk material is crushed by the jaw crusher to the required grain size, the raymond mill is used to send the material to the storage hopper, and then the vibrating feeder is evenly and quantitatively fed into the main grinding chamber for grinding, after grinding. The powder is carried away by the fan airflow.
After being graded by the analyzer, the powder with fineness enters the large cyclone collector along with the gas flow through the pipeline, and is separated and collected, and then discharged through the powder tube as finished powder. The air flow is sucked into the blower by the return air pipe at the upper end of the cyclone collector. The entire air flow system of the machine is closed and circulates under positive and negative pressure.
The above is a detailed introduction about the structure and working principle of Raymond Mill. The relevant staff can refer to it. Before the raymond mill is installed, it should be properly kept. A complete maintenance system must be established to prevent the machine from being exposed to the sun, rain or rust. In the process of using Raymond Mill, it requires a fixed number of people to look after it. It also requires the operator to have a certain level of technology, but also to understand in detail its structure and working principle, and familiar with the operating procedures.

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill. It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill?
1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent.
2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range to the 80-800 mesh range.
3. The wind transport and finished product collection system was updated to have a negative pressure, secondary dust collection and high efficiency dust collector, so that the finished product can be collected more thoroughly.

Raymond Mill’s Structure and Process System Introduction

The equipment is called a roller mill when the material is pressed between two rolled rolling surfaces or between a rolling grinding body (ball, roller) and a track (plane, ball, plate) under pressure. Also known as a centrifugal mill. There are many types of roller mills, such as disc mill, ring mill, roller mill, raymond mill, pendulum mill, etc. This article mainly introduces the structure and process system of Raymond Mill.
Raymond Mill, also known as suspended roller mill, has the advantages of stable performance, convenient operation, low energy consumption, and fine product fineness. Therefore, it is widely used in fine grinding of coal, quartz, talc, graphite, heavy calcium and chemical raw materials.
Raymond Mill’s structure is shown in Figure 1. The roller is installed on the plum blossom frame by the shaft. The plum blossom frame is driven by the transmission device to rotate. The grinding ring is fixed and the material is fed from the side of the machine body through the feeder to the machine, and is grinded between the roller and the grinding ring. Crushing action, the airflow is blown in a tangential direction from the lower part of the grinding ring, passes through the grinding zone between the roller and the disk, and enters the upper wind power classifier together with the dust. There are 3~5 rollers hung on the plum blossom frame, orbiting around the central axis of the body. Due to the centrifugal force generated by the revolution, the roller presses against the grinding ring and rolls on it. The material fed into the mill is shoveled by a blade and lifted between the roller and the grinding ring.
Raymond Mill’s process system is shown in Figure 2 below. After the material is coarsely crushed by a jaw crusher, it is fed into the bucket elevator and then falls into the feeding hopper, and is fed into the lower part of the Raymond Mill ring in a tangential direction through the electromagnetic vibrating feeder and lifts the ground material. After being graded by a classifier (or classifier) ​​set in the mill, the coarse particles fall down and are ground again, and the fine particles are collected by a cyclone collector to become a product. For this system can be sent into the hot air, Raymond Mill can be used as a combination of grinding and drying, feed moisture up to 10% to 12%, while the product’s moisture is close to zero.

Raymond Grinding skillfully manages coal gangue

Coal gangue is a kind of main coal solid waste, which is discharged during the process of coal mining and coal washing. It is a kind of dark gray rock with low carbon content and harder than coal, which is associated with the coal layer during the coal formation process. Coal gangue has high recycling value, but it is difficult to use. It really makes the majority of coal owners love and hate; at the same time, along with the accelerating pace of China’s coal mining, solid waste discharged from coal mining process is increasing.
