Graphite negative electrode material (graphite, artificial graphite, spherical graphite) Crusher special equipment processing process, on-site no dust pollution, guarantee the clean and dryness of the environment. Graphite pulverization is highly high, large production! Can choose special equipment according to different raw materials, fully automated control, low energy consumption. The pulverized grading accuracy is arbitrarily adjustable between D97 = 3-74 microns. Granular appearance plastic function, spherical graphite "potato shape". Bag dust removal, appendedly anti-blow, offline cleaning, 75% collection rate, effectively reduce the loss of raw materials.Preparation of the positive electrode material and unparalleled comminution technology. Similar techniques among the deep processing are, including refinement, modification, microporous technologies in the surface level, and microporous technologies in the surface level. Through long-term transformation, the ultrafine pulverizer achieves complete performance. The normal production of the positive electrode material is related to a variety of processes. In the production of positive electrode materials, ultrafine pulverizer is usually used. The operation mechanism of the ultrafine pulverizer will help optimize the pulverization process. This article identifies the multi-probabilities of the pulverizer and effectively detects the path of optimization. 1. Crushing apparatus for clearing the ultrafine characteristics of the fundamental mechanism, according to the following fundamental mechanism: the most mixed multi-raw material is produced, and is added to the system. The hopper is equipped with a feeder in a double helix architecture. The preset feed rate is automatically changed according to the real load of each stage, and can control the true particle size in the feed. A crushing chamber, preset 420 mm unique diameter. The medium device preset in the crushing chamber is a circular meter ring of adjustable characteristics. The discharge port of the crushing room can also be installed in the graded wheel of each specification. The top of the rotor is equipped with a hammer prepared by a wear-resistant ingredient. Parallel, it is a liner within the housing, which is treated via wear-resistant steps and reserved a gap. The positive essential material is absent from each other in the rotating airflow. At the same time, under the centrifugal projection of the rotating body, the inner wall preset in the pulverizer, continuous shear and impact, the material is pulverized. The powder is hit by the ultrafine architecture and shortens the original pulverized time. The crushing room has a rotor with a clear grading performance. The particles of this accessory are then transported until the pulverizer. The gravel of the material is sandwiched, and the residual diverse debris can be arranged in addition to the slag fittings internally. Delivery feedstock processing, enter the collectorThe system is made into a cathode material available. 2. Crusher under the ultrafine manner in the ultrafine manner of the commissioning characteristics, with a micrometer level of preparation. In the daily production of positive electrode materials, a hierarchical fitting should be equipped with efficient characteristics. Specifically, the particle size of the positive electrode material is influential, the influence of the yield is within the design of the following key points: the first, the radius of the circular architecture should be prepared. Such an inner diameter in which the radius is solid, affecting the subsequent period of the material. If the original inner diameter is increased, it will become shorter. In this case, the particle size of the crushed product will become rough. The material reciprocates, the positive products prepared, and the hidden hidden dangers are hidden. To this end, the raw materials and fineness of different characteristics should be followed, and the absorbing ring under suitable specifications should be selected to support the application. Second, the slaglet specifications of the pulverization room are also related to the material weight. The fundamental performance of the slag mouth is to grind the debris that is difficult to pulverize, properly ground to improve the purity. If expanded the slaglet, the amount of treated cost is increasing, and the raw material that is not ground is discharged, resulting in a waste of waste. Usually, the rumor has a good adjustment ratio, which can be set to 9% of the total amount of material. The positive electrode material having a high purity can close the slaglet. Third, a hammer with a pulverizer, a liner under a certain specification, should pay attention to the interval. If it is preset, this partition is predetermined, which will limit the quality of the crushing product. The hammer head and the unique liner are set to be set to 2 mm. The large interval will add the original material thickness; a small interval, which will also reduce the real pulverization effect, and reduce the effectiveness of the use. 3. Variety of optimal ideas 3.1 Develop a variety of products of ultrafine characteristics of the best process, according to the set granular level, can be divided into the product of the packing, with coating characteristics. Among this, the usual preparation process comprises the following side focus: the initial period of preliminary pulverization, ultrafine characteristics of pulverization, calcination of the layered characteristics, the continuous dispersion, and the positive electrode material unique. Increase the original pulverization accuracy, change the set calcination specification, and the association technique within the diffusion process. For example, the pass rate of the calcined material can be set to exceed 90%. 3.2 Lifting the purity requirements associated with existing purity positive electrode materials, including self-belt purity via a crushing. Purchase materials for high purity features, through super fineAfter the crushing of the situation, the purity will be changed. For example, a positive electrode material of the second stage is in the preparation, the original material transported, the purity is determined to be 74%; after the pulverization, 10 microns have passed the pass rate to 85%. The discharged debris emissions only reached 1.4%. This is characterized by a slag, which can improve the purity level. 3.3 Small combination of ultrafine characteristics in other categories, also with dispersion characteristics, and to deliver such features. For the positive material material in the lightweight, it is commonly used to prepare the chemical method. Among the preparation processes, some of the conditions are often changed. For example, the raw material has not sufficiently reacted; the granules of the pulverized particles are still large; the particle agglomerates under ultrafine manner. Under this state, the prepared positive electrode product is hidden with unstable disadvantages. To this end, the set working condition parameters are changed, and the commonly seen agglomeration status is reduced, and it has facilitated subsequent dissipation and depolymerization. The results of the survey are characterized, and the materials that crush a variety of characteristics, closely related to production and fineness value measured. The material, particle size in different categories, the computational Mohs hardness, the water components hidden, will have differences. At this time, the ultrafine hammer head can reduce the wear of the liner within the framework. The tough material under the sheet-like should be changed to the bunch of crispy properties to facilitate pulverization. Ultrafine pulverizer, is recognized as a pulverization device with a dry firing via a long time. In the future, it is necessary to expand the planned preparation scale. The crushing device in the grading architecture is put into trial operation, which should be able to resolve this problem.
