Chalk is a soft brittle microcrystalline limestone powder containing more than 99% carbonate minerals. Chalk has another name, called clay powder, which is a branch of calcium carbonate and calcite that deposits sediment. Chalk is the remains of some single-cell plankton. The application of chalk is almost the same as calcite, usually used in plastic products including belts, films, boards, tubes and bags. And chalk can also be used in rubber, paper, toothpaste, painting and adhesives. In addition to these, there are some specific applications for chalk, chalk production and medical applications. Chalk also needs to process the application. People usually use Raymond mills along with chalk processing equipment. And products can be used anywhere except medicine. Why do we choose the Raymond mill pulverizer? The Raymond mill was introduced to China in the 1980s as one. After that, it has been more than 20 years since Raymond has been witnessed for more than 100 years since its birth. At first, the Raymond mill was designed for coal crushing, which is suitable for coal and small ash in the United States. The Chinese powder industry is currently undergoing rapid development and the Raymond mill has also improved a lot. Our high pressure mills represent the new Raymond mills and add high pressure springs. We use roller ring connections to optimize wind power systems and improve classification.

Ultra-fine vertical grinding machine for green silicon carbide environmental protection

Green silicon carbide micropowder is a kind of cutting auxiliary material in the new energy photovoltaic industry. The processing method is similar to that of black silicon carbide, but the requirements for raw materials are different. After the ultra-fine grinding of green silicon carbide, the powder is in green energy technology. It is widely used and is also a new type of green material. As the global warming effect intensifies, the Antarctic glaciers will slowly melt and will disappear by about 300 billion tons per year. The control of carbon dioxide in the air should be emphasized. In addition, the consumption of non-renewable energy is increasing, and the energy crisis has become a must for some countries. The problem of finding renewable resources has become the focus of the world. Low-carbon environmental protection and green energy have become the direction of future economic development.

With the development of science and technology, solar energy technology has become one of the renewable and highly valuable green energy sources in the 21st century. It is environmentally friendly, efficient and renewable. The development of the photovoltaic industry can not only effectively solve the problem of resource shortage, but also improve the economic status. And as a mainstream industry that can be a resource in the development of the new century. The cutting technology of crystalline silicon cells in the photovoltaic industry is inseparable from the auxiliary materials such as green silicon carbide micropowder. The green silicon carbide mainly contains petroleum coke, high-quality silica and other materials in the resistance furnace for high-temperature smelting, and then ultra-fine grinding and other milling equipment. Grinding, so the development of the photovoltaic industry also drives the development of the milling industry and the mining industry. Whether high-quality silicon or green silicon carbide after smelting is inseparable from processing equipment such as crushers and vertical roller mill, green silicon carbide powder. Production has also become an indispensable part of the photovoltaic industry.

The application of green silicon carbide micropowder in the photovoltaic industry has also enabled industrial mills to embark on new green energy roads. Superfine grinding, crushing machines and other mining machines have long been limited not only to the development and utilization of mineral resources, but also in the development of green materials and industrial slag. And solid waste recycling and other aspects have an important role. The utilization value of powder particles is constantly being excavated, and the technical performance of all aspects of milling equipment technology needs to be continuously improved.

In the working process of the Calcium Carbonate Plant, different parts play different roles. When used, the wear is different. The wear will cause the performance of the equipment to gradually decrease. When the wear is serious, the parts can no longer assist the production. The smooth progress, this time you need to replace the parts, different parts have different replacement cycles, then when it is required for the pallet, when do you need to replace it? 

In the interior of the mill, the blade is mainly welded on the pallet. The blade is an important part that shovels the material into the middle of the grinding ring and pulverizes. It has direct contact with the material, so it is in production. There will be wear and tear, which belongs to one of the wear parts of the equipment. In the production, the replacement cycle is shorter than that of the parts such as the pallet. Generally speaking, many customers will have doubts. The plates are welded together, so when the blade is replaced, does the pallet need to be replaced? In fact, it is necessary to look at the wear of the pallet. Generally speaking, if the pallet wear is not serious, it can be replaced without replacing the blade, because if the blade is replaced directly with the pallet, the cost will be wasted. For one thing, after replacing the blade, it is only necessary to weld the new blade to the pallet at a certain angle. This is a relatively cost-effective way. In the interior of the mill, the pallets are usually fixed on the blade by connecting screws, and some of the three holes are four holes, but in general, the pallet needs to be fixed to enable the blade. It is fixed on the pallet, so whether it is the installation process of the new machine or the welding process after the blade or the pallet replacement, it is necessary to ensure that the pallet is fixed, so as to ensure the stability of the blade and ensure the production. Going smoothly.

The quality and quantity of machines is the ultimate goal of each manufacturer. Such efficiency plays a key role in the development of an enterprise. Therefore, improving the output and quality of the machine is a hot spot for machine manufacturers and users. Mills have been widely used in many industries, so how to adjust the fineness and output of the marble grinding machine, the following SBM milling experts for you to analyze: The mesh size of the mill is inversely proportional to the output. As long as the fineness is high, the output is bound to be low. This is because the high fineness requirement means that the speed of the analyzer part is increased, and the coarser material is unpassing, and it is necessary to re-grind it. This lengthens the grinding time of the material inside the mill, which means that the time taken for the finished product to come out in a unit of time is long, so the amount is reduced. In the production process of the mill, the conditioning of the air volume and fineness needs to be carried out frequently. In order to meet the needs of production, we must master some common sense of grinding machine conditioning. Today we will share with you several common methods for adjusting the fineness of the mill: the diameter of the spacer ring and the diameter of the spacer ring determine the particle in the crushing room. The time of stay. The larger the diameter of the spacer, the shorter the residence time of the particles, the larger the particle size of the pulverized product, the higher the output, and vice versa; the air volume can be controlled by adjusting the butterfly valve at the outlet end of the mill. When the air volume increases, the product particle size increases, and vice versa; the slag discharge amount adjusts the slag hole size of the slagging device to control the slag discharge amount, which can improve the product quality and purity; the graded impeller and the spacer ring gap, the gap Decrease, the product becomes thinner; the gap increases and the product becomes thicker. SBM Heavy Industry Machinery Co., Ltd. is a professional mill manufacturer, which can develop a reliable and cost-effective coal mill according to your needs. In addition, the company also produces high-pressure suspension roller mill, European version of the mill, Raymond mill and other milling equipment, happy customers to inquire, we will be happy to help you!

For the construction waste crusher, any failures that occur, or any damage to the parts, need to be handled in a timely manner. The purpose of this treatment is to restore the performance of the equipment, inside the equipment. The eccentric shaft and the bearing bush play an important role, and the two play a great role in production, but at work, the two will also wear or damage, which needs to be processed in time, here Let us introduce the maintenance methods of these two parts. First of all, if the shaft of the construction waste crusher wears less, we can repair it by turning the lathe, mainly to repair its geometry, but reduce the diameter of the bearing hole accordingly, and In production, if the operation is performed several times, when the reduced size reaches 5%, the operation cannot be performed because the parts repaired by this operation cannot meet the equipment. The work process, the need to replace the shaft; Secondly, the construction waste crusher works under impact load. The service life of the babbitt-lined bushing is limited. Once it exceeds the specified period, it needs to be recast. If the eccentric shaft is If the gap between the bearing bushes is 1.5 times, it needs to be adjusted or replaced. If the oil groove is 1.5 mm, the oil groove should be re-adjusted. When machining the bearing bush, the following requirements must be met: the surface of the babbitt should be uniform in color. Matt, silvery white, should not have ash, cracks, blisters, shrinkage holes and other shelling phenomena; The article mainly introduces the maintenance of the eccentric shaft and bearing bush of the construction waste crusher. The above analysis of this problem is more detailed, mainly from two aspects, and introduces the eccentric shaft of the machine and the maintenance method of the bearing bush failure. And the timing of its replacement, as well as the requirements that the bearing bush needs to meet during processing. These aspects are all to help the construction waste crusher to work better. It is a few aspects that we can't ignore in production.
