Influence Factors Of Ultrafine Mill Efficiency

Host: With the development of our science and technology, the application of vertical roller mill is wider and wider. Ultrafine mill plays a more and more important role in our foundation construction. How to improve the ultrafine mill¡¯s work efficiency? This is a key problem. So today, we invite the expert¡ªMr. Wang to give us a detailed introduction about the influence factors of ultrafine mill efficiency. Welcome! Mr. Wang: Good morning, everyone. I will try my best to solve your problems. Host: Most users are concerned about the influence factors of ultrafine mill efficiency. So, can you first relate them on the whole? We can have a general impression. Mr. Wang: I¡¯m glad. Today, I will introduce the influence factors form three big aspects. It mainly contains the material property, vertical roller mill design and the manual operation situation. Every aspect also includes many small other aspects. The following is my detailed introduction. Host: We are a bit unable to hold ourselves back. So how about the material property? Mr. Wang: The material property contains the material feature, the feed size and the product fineness. The material¡¯s hardness, composition, viscosity, moisture and finished product particle size all will affect jaw crusher¡¯s work efficiency. Grindability factor is related with the mechanical strength, dissemination characteristics and the grinding ratio. Ore is harder, and grindability is smaller. Then, handling capacity of powder grinding is low. Host: This aspect is easy to understand. How about the other two aspects? Mr. Wang: The vertical roller mill¡¯s type, speed, diameter, length, and the liner type all will have an effect on the work efficiency. Manual operation situation includes the load ball system, grinding concentration and feed rate etc.. Sometimes, the worker¡¯s operation situation will play a great influence on the machine efficiency. So we must pay attention to it. In these three aspects influencing on grinding efficiency, in generally, after two aspects are not common. The main is the first kind of material properties, feeding size, material requirements. They maybe have more effects. We should strengthen the attention. Host: This is a great introduction on the influence factors of ultrafine mill efficiency. Thank you, Mr. Wang! Mr. Wang: You are welcome.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands
