| add to favorites | the development of Raymond mill | Cars |
| Especially for the development of large Raymond mill, there is no mature experience to learn from, and no mistakes are allowed in the design. Therefore, it is necessary to improve the design efficiency and quality, and enhance the independent innovation ability and market competitiveness of enterprises by virtue of the integration of multi-disciplinary technologies. On the basis of the integration of Raymond mill, computer technology and network technology, the trend of digital development has been formed. Recalling the development history of crusher, there are mainly jaw crusher, impact crusher, conical crusher, hammer crusher, ultra-fine crusher, roll crusher, impact crusher and so on. There are many kinds of crushers, so they have different names. Vertical crusher (the main shaft is vertical) has become a hot-selling crusher product with breakage instead of grinding since it was introduced in the 1980s. As a fine crusher, its average discharging granularity is less than 3-4 mm and 90% is fine powder, which reduces the feed granularity of the ball mill and increases its output by 20-30%. After more than 20 years of development and evolution, vertical crusher from the first generation to the fifth generation, from a single blow crushing evolved into impact crushing, the service life of the hammer head is four times longer than that of the old crusher. Vertical impact crusher, the representative product of vertical crusher, is widely used in material grinding engineering in iron ore, gold mine, cement, glass, ceramics, electric power and iron and steel industry. | ||
| add to favorites | The Development of Cement Sand Making Machine | Cars |
| The cement sand making machine is a new type of sand making equipment designed and manufactured in accordance with the similar characteristics and market needs at home and abroad.In 1970s, our country introduced the eight-hole cement sand making machineabroad.It uses river sand and a small amount of fly ash and cement to suppress lime sands.However, the rotation of the disc can only press one piece of sand at a time, and the output is low. When the large amount of industrial waste fly ash is used, there is a stratification phenomenon in the lack of exhaust. It cannot meet the requirements of the national wall reform and not meet the national industrial policy at that time.In order to improve the output and make up for the disadvantage of easy delamination of the defective products, the domestic mechanical engineers have developed a crankshaft type double crank mechanical pressing machine with two blocks, three blocks or even four blocks. Because of its special pre pressure buffer design and the adjustment of the depth of the material, it can be qualified for the national policy of industrial structure of the new wall material with large amount of fly ash as raw material.The equipment inherits the eight-hole turntable type sand press without the need of the bracket, the advantages of the direct palletizing, and the stability and reliability of the mechanical motion, and 15~17 times a minute to ensure the production and quality of the single equipment. | ||
| add to favorites | Calcium carbonate beneficiation method | Cars |
| If the global new energy vehicles, especially the pure electric vehicles represented by the US Tesla, grow faster, the global demand for calcium carbonate will reach 350,000 tons by 2010. As for the supply of calcium carbonate, there will be a gap in the supply and demand of global calcium carbonate by 2019. Calcium carbonate beneficiation equipment includes crushers, ball mills, jigs, flotation machines, etc., as well as some auxiliary equipment to form a complete production line. The hand selection method is a sorting method based on the difference in color and appearance between calcium minerals and gangue minerals. The selective particle size is generally 10 to 25 mm, and the determination of the lower limit of the particle size depends on economic benefits. Hand selection is the earliest method of mineral processing used in the history of calcium mine production. In addition to spodumene, the hand selection is also used to pick calcium concentrates from lithionite, petalite, and amblygonite.The hand selection method has been generally replaced by flotation or other methods due to its high labor intensity, low production efficiency, and large waste of resources. | ||

| add to favorites | limestone in the digestion process | Cars |
| 1. Digestion efficiency is high. Considering the characteristics of limestone digestion process, a comprehensive water-adding curve is designed with different nozzles to keep a certain humidity in the digestion process. At the same time, a special digester is used to stir the blades, which produces strong stirring to the limestone in the digestion process, and greatly improves the digestion efficiency of limestone. 2. The blade is non-sticky. The front and back nozzles are installed on each stirring blade of digester by water-adding nozzle. The impeller of quick limestone stirring is washed in front and back once every turn, so the blade will not stick. 3. Good environmental effect. Because the front section of limestone digestion is equipped with a sealing section matching spiral blade and circular shell, the steam and dust generated during the digestion process of limestone slakers will not be emitted from the inlet and outlet of the limestone digestion section. It avoids the steam from the inlet and outlet of the limestone digestion device from encountering an electronic scale or spiral scale into water. The sticky mud on the scale pole affects the accuracy of the scale, and the digested quick limestone is discharged in. So without dust, environmental protection effect is good. | ||

| add to favorites | Solution of jaw crusher jaw plate wear | Cars |
| Mixed crushing refers to the limestone production process in which two kinds of raw materials are fed into a crusher in a certain proportion for crushing. Common mixed crushing are limestone and marl, limestone and shale, limestone and clay, etc. Screening raw materials before crushing, only crushing the screening materials, often can achieve good results. For example, nowadays cement is produced by a new dry process with pre-decomposition, which improves the silicic acid rate in the raw material mixing, and often needs to be mixed with siliceous raw materials. The contact between the jaw plate and the machine surface is not stable; the eccentric shaft rotates too fast to remove the crushed materials, which results in jamming of the crushing chamber and wear of the jaw plate. Material properties have changed, but the crusher has not been adjusted in time; the angle between the movable jaw plate and the fixed jaw plate is too large to exceed the normal range; The strength and wear resistance of the jaw plate are not good. | ||
| add to favorites | What is the use of quartz sand | Cars |
| Quartz sand can also be used in other industries, such as metallurgical industry, refractory material manufacturing industry, plastic industry, abrasive industry, rubber manufacturing industry, chemical industry, construction industry, etc. In glass manufacturing, the raw materials used in float glass manufacturing are sea sand, mica sandstone powder, soda, and calcite. They are prepared according to a certain proportion. Then the glass is melted at high temperature and processed. It can be seen that quartz sand plays an important role in glass making. Silicide is needed in the manufacture of ceramics, and the silicide is obtained from quartz sand. Silicide is also an important refractory so quartz sand can be used in the manufacture of refractories. Silicides are also useful in metallurgy, construction, and chemical industries. Silicides can be used as additives or raw materials in the metallurgical industry, as well as in building concrete, road materials, and cementitious materials. In the chemical industry, it is mainly used as raw materials such as sodium silicate. Quartz sand can be used not only in the above industries but also in two industries with high-tech content. For example, the aerospace industry and the electronics manufacturing industry, the silicon obtained by the purification of quartz sand grinded by Raymond mill is an important aerospace industry material, so its economic value and scientific and technological value are very high. | ||
| add to favorites | The disadvantage of the talc mill | Cars |
| When the crushing force acts on the frame, the talc mill occupies less space than the large cone crusher, produces less deformation to the installation base, and has greater production capacity than the jaw crusher. The disadvantage of the talc mill is that the crusher concentrates on the center of the talc, so it needs a high-strength shaft, bearing and supporting mechanism. talc mill has been used as supporting equipment for E-crusher, cone crusher and other crushers, as a secondary crushing of materials, that is to say, talc millhas been in a supporting role. Talc mill can be used continuously for more than one year. When the wear is serious, the cover can be replaced by removing it. Small maintenance and low cost are incomparable to any other type of crusher in China. The talc gap of the abrasive talc body of thetalc mill can be adjusted arbitrarily from 1 mm to 20 mm. After adjusting the talc gap according to the requirement of crushing size, the crushing size can be conttalced reliably, and all of them are discharged from below the crushing chamber with ideal size. | ||
| add to favorites | the Quartz Stone Raymond Mill | Cars |
| The ore is ground in the Raymond mill mainly by the impact crushing force generated when the raymond mill is thrown off and the relative sliding of the raymond mill to the ore. Impact crushing force, grinding and crushing capacity and processing capacity have a certain relationship with the size of the raymond mill. According to the test results of the predecessors, the size of the raymond mill is proportional to the impact crushing force, the grinding and pulverizing ability, and the processing amount of the raymond mill falling under the same amount. It is inversely proportional to the single energy consumption and grinding fineness of the raymond mill within a certain range. If the raymond mill is too large, the grinding grain size may not be reached. Therefore, in the case of large hardness, large particle size and large grinding grain size, the raymond mill size is appropriately increased, and the effect is remarkable in increasing production, energy saving and consumption reduction. | ||
