    • crushermachine169 has written a new blog article "Ultrafine mill more common fault summary and solution" 04.20.2018

      As one of the more popular milling equipments currently used, Ultrafine mill have been widely recognized by users for their excellent performance. However, the smooth production of ultrafine grinding mills directly affects the production of ore milling plants. Benefits, so it is necessary to properly maintain the mill, master some of the more common faults and solutions of ultra-fine mill is to help users fully understand the best magic weapon Ultrafine, the following Shanghai SBM summary for the majority of users What are the common faults and solutions for some ultra-fine mills?
      First of all, the most common is the failure of the bearing wear of the ultra-fine mill. The reason for the bearing wear of the ultra-fine mill is that the bearing is mixed with impurities, which makes the friction increase and wear; the other is the bearing bearing is too large. This leads to increased friction and wear. The last reason is that the lubrication of the bearing is not in place. To solve the above three problems, the first need to always lubricate the bearing, the role of lubrication is mainly to reduce the friction between the bearing and other components in the mutual movement, thereby avoiding the bearing wear failure; In addition, when the bearing load exceeds a specific value After fatigue is used, the user needs to replace it in time and be careful not to allow the machine to operate with fatigue. In addition, because the working environment of the ultra-fine mill is rather harsh, some impurities will be mixed into the bearing. It is unavoidable that the user needs to do a timely cleaning of bearings, regular lubrication, and good sealing work.
      After the failure of the bearing is solved, the next step is the breakdown of the vibration of the ultrafine mill. There are three reasons for this problem. First, it may be because the high-hardness material enters the grinding chamber of the machine. The ultra-fine pulverizer vibrates and generates a loud sound. To solve this problem, it is necessary to control the type of material entering the grinding chamber to eliminate the malfunction. Second, because the feed size is too large, when the size of the material entering the machine grinding chamber is too large, the machine consumes more energy to grind large materials, so it needs more grinding power to grind the material, and when When the power exceeds the maximum strength that the machine can withstand, it will inevitably cause product vibration, and because the material will break and the flour will make a sound, it will produce a loud sound, but this sound will continue for a little while, So don't worry too much about it. Thirdly, it is related to the stability of the machine. We all know that ultra-fine pulverizers are cemented on the concrete foundation through foundations, bolts, etc. If cracks or loose bolts occur in this fixing method, it will also lead to The machine vibrates with the sound, and to solve this problem, it is only necessary to reinstall the machine and re-cast the concrete foundation.
      Another problem is also more common, that is, the problem of excessive temperature of the ultrafine pulverizer. To solve this problem, you can first check whether the extension pipe is unimpeded, the viscosity and the grade of the oil meet the requirements; the roller bearing into the powder bearing should be timely refueling according to regulations, regular cleaning, replace the oil seal; grinding roller ring bearings to be regularly refueling .

    • crushermachine169 has written a new blog article "Precautions after Raymond Mill shutdown" 04.16.2018

      I often emphasize to you all about the precautions when starting the Raymond Mill. Are there any precautions you should know about downtime? If you ignore some small details when shutting down, a little carelessness will affect our normal use for the next time. Today we will talk about the raymond mill shutdown notices that should be kept in mind.
      1. It is forbidden to stop the lubrication and water cooling system before the temperature of the Raymond Mill main body and the main bearing has not dropped to room temperature.
      2. After the Raymond Mill has stopped moving, it should be immediately connected to the high-pressure floatation device to prevent damage to the bearing alloy and hollow journal due to cooling and contraction of the grinding body until the grinding body is cooled to normal temperature (ambient temperature).
      3. When the auxiliary drive is used to move the mill, the inlet opening of the mill exhaust fan is closed to 20%, and the hot air main valve is fully closed.
      4. After the main and auxiliary engines of the system are parked, the valves should be closed and the recorder switch should be turned off.
      5. The exhaust gas treatment system shall adjust the system pressure according to whether the rotary kiln system stops the material after the grinding is stopped (such as the valve of the humidifying tower and the size of the relay fan opening).
      I hope that everyone will be able to strictly meet themselves when they open the Raymond Mill, operate the mill, or stop. Turn the machine on and off according to the correct method. Do not ignore some details of the operation and avoid affecting the normal operation of the mill. Go for some unnecessary trouble.

    • crushermachine169 has written a new blog article "Raymond Mill's Structure and Process System Introduction" 04.14.2018

      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.

    • crushermachine169 has written a new blog article "Tricyclic mill can maximize the value of ore resources" 04.10.2018

      Tricyclic mill is a kind of processing equipment for fine powder and ultrafine powder. The Ore Milling Equipment is mainly used for processing non-flammable and explosive brittle materials with Mohs hardness of <6 grade. China as a developing country, three-ring mill The application is the most, China's mineral resources and types are also relatively complete, and one of the countries with high self-sufficiency in minerals.
      Mineral resources as non-renewable resources, reserves are also very limited, how to make full use of and develop mineral resources is the future direction of development, tricyclic mill can improve the comprehensive utilization of mineral resources, and thus maximize the value of limited resources effect.
      In the process of processing minerals, the tricyclic mill has a direct relationship between the utilization of resources and the fineness of the materials. Take coal as an example, the finer the fineness of processing, the greater the air contact area and the more fully the combustion. The heat emitted by coal and pulverized coal of the same weight will also be very different. The combustion of coal is not sufficient, the production of carbon dioxide is high, and solid waste is also produced. Therefore, the finer the material, the more uniform the utilization efficiency is. high.
      In addition to considering the utilization efficiency of mineral resources, the waste of resources is one of the more common problems, especially for tailings and other resources that are discarded at random. If the tailings and other products are used properly, their available value is also very large. , Ore Milling Equipment can use the tailings resources after grinding in the construction industry, as a retarding map, cement ingredients used, the current application of a variety of tailings after grinding applications in the construction industry more and more.
      Different mineral resources can often be replaced with new resources. Industrial production will be accompanied by solid waste, such as coal gangue, slag, etc. If these solid materials are handled properly, they can be ground to treat different types of grinding. Materials, concrete and other materials can be processed into fine powder through a three-ring mill, and the use value will be higher.
