  • Deep Processing Of Slag And Recycling Of Slag

    In 2017, the national industrial solid waste output was 1.2 billion tons, and the comprehensive utilization rate was only 55.7%. Slag is the main solid waste that affects the environmental load of black metallurgy industry. In 2017, China made 272 million tons of steel and produced 146.19 million tons of smelting waste (including 50 million tons of steel slag and 90 million tons of blast furnace slag). With the comprehensive utilization of 128.48 million tons and the accumulation over the years, the total storage capacity is 200 million tons, covering an area of 30000 mu. The open-air storage of smelting waste occupies the land, pollutes the toxic soil, water and atmosphere, seriously affects the ecological environment, resulting in obvious or potential economic loss and good source waste. It is estimated that the economic loss per ton of smelting waste is 14.25 yuan, resulting in an annual economic loss of 2.85 billion yuan. Therefore, the harmless and multi-source treatment of smelting waste is the focus that our country and even the world attach great importance to, and also one of the central contents of promoting circular economy.

  • Analysis Of The Main Factors Affecting The Price Of High Finely Grinding Machine

    High fineness grinding machine is a kind of grinding equipment used to process high fineness powder. Compared with the traditional Raymond machine, this equipment not only has higher fineness and stronger grinding ability, but also has a decrease in energy consumption. As a more commonly used mining grinding equipment, this equipment has been favored by the majority of users for its practical, applicable, novel, cost-effective and other advantages. For the price of high fineness grinding machine, It must be the concern of everyone. For this equipment, its price needs to be determined by considering many aspects comprehensively, and the price of high-precision grinder will also be affected by the following factors. 1. Different manufacturers have different production technology, operation process and raw materials, which makes the price of high-precision pulverizer different when it leaves the factory. Therefore, when preparing to invest in the equipment, users should go to large-scale enterprises to buy it. Such enterprises generally have relatively skilled production technology and perfect operation process. The equipment has rich experience in all aspects of production, which can not only ensure the quality of the equipment, but also the price of the equipment is relatively favorable. 2. The market situation of high fine grinding machine, like other equipment, will be affected by the market. When the production quantity is higher than the demand, in order to sell more equipment, the manufacturer will generally reduce the factory price; otherwise, it will be raised appropriately. At present, the output of high fineness mill has not reached saturation, so the price of equipment still has the possibility of rising, so the users can seize the opportunity. 3. Model and type of equipment model and type also determine the price of high-precision pulverizer. Different users have different requirements on the granularity, output and performance of finished materials. Therefore, in order to meet the needs of users, manufacturers will produce various grinding equipment according to the needs, so that their types and models can be diversified, and when the types and models of equipment change, the price of equipment will also be affected.

  • What Should Be Paid Attention To In Detail Work Of High Fineness Mill

    Details determine success or failure. This is a sentence we often hear in our life. It applies at any time. Of course, the same is true for the high fine grinding machine. We all know that the high fine grinding machine is a kind of mechanical equipment used to process the fine powder. In the grinding production, there are places that need our attention, such as the installation and debugging at the beginning, the operation at the later stage, etc., which are very important. The next part is to introduce the details of the high fine grinding machine. First of all, the installation of the equipment. During the installation of the high-precision pulverizer, attention should be paid to the location of the accessories and the gap between them. These are important factors that determine whether the accessories can cooperate smoothly in the production, and whether the production of the equipment can proceed smoothly. Therefore, attention must be paid to the correctness of the installation. Secondly, the commissioning work after the installation of the high fine grinding machine mainly refers to the no-load and on-load test machine, which is mainly to detect whether the equipment is correct during the installation and whether there is a hidden trouble in the production, so as to more fully detect whether there is a fault in the equipment. There is also the daily maintenance of the high-precision grinding machine, which is mainly to reduce the wear or failure of various parts in the production process of the equipment. Correct maintenance can better extend the service life of the equipment, reduce the cost of maintenance, and improve the efficiency of the equipment.

  • The Service Life Of High Fine Grinding Machine Is Mainly Affected By These Two Factors

    As a kind of special mechanical equipment for processing high and fine powder, high and fine grinding machine is an indispensable equipment for those manufacturers who have requirements for materials. However, for mechanical equipment, it has a certain service life, and its life will be affected by many factors in production, resulting in a reduction of life. In a word, the main factors leading to the reduction of life of high and fine grinding machine are To have these two, the following for you to specifically analyze which factors will lead to the decline of the service life of the high-precision grinder. 1、 Users in the operation of 1. Wrong operation method, in the use process of high finely grinding machine, users need to take the correct operation method to operate, if often take the wrong method, although the equipment can operate normally, but you will find that the service life of high finely grinding machine will be reduced after a long time. 2. We all know that the user can take correct maintenance for the high fineness grinder on a regular basis, which can greatly improve the service life of the equipment. However, if not, not only the failure rate of the grinder will be increased, but also the service life of the equipment will be decreased. 2、 The influence of environmental factors on the service life of high-precision pulverizer will also be affected by environmental factors. If it is located in a relatively hot area, the heat dissipation of high-precision pulverizer will be affected, so the phenomenon of high temperature will appear during production, resulting in failure. If it is in a humid area, it is easy to cause rust in the high-precision grinding machine, which will cause equipment aging and so on. Therefore, in the actual production, I need to take the corresponding methods according to the surrounding environment, such as coating antirust paint or placing it in a ventilated environment. In this way, the influence of environmental factors can be avoided, which leads to the decline of the service life of the high fineness mill.
