1. There are not many proct introctions about sand separator, but its application in practical proction and life can not be ignored. It's hard to avoid losing when selecting. I have doubts about the price. The following editor will give you a detailed introction about the factors that affect the price of the sand separator. In the field of economics, we can understand that the general factor affecting goods is supply and demand. If there is more supply, the price will become low. If there is less supply and demand, the price will be very high. The procts of the sand separator manufacturer are the same
according to the above, although non professionals may know little about it, it has many functions. Therefore, in the related fields, there are a lot of sand separator manufacturers. Therefore, the supply of sand separator (Shandong Zhongshun machinery) is relatively large, so its price is relatively reasonable. In addition, quality is also a decisive factor affecting the price of sand and stone separator. We all know that the better the proct, the higher the price. This is a knowledge we are already familiar with. Well, it also requires us to polish our eyes when we buy, select the best procts, and have a good use experience. The factors that affect the price of sand and stone separator also depend on many details such as the market. The market is changing rapidly. A small change may lead to a big change in the price. I hope you can buy the right procts.

silicon powder with good activity:
the activity of silicon powder obtained by different milling methods is different, The factors that determine the activity are microstructure, specific surface area, particle size distribution, surface protection and equipment steel consumption< (1) microstructure:
for silicon whose chemical composition meets the requirements, the best microstructure has been obtained in refining to ensure that it has the best activity to participate in the reaction, that is, its nature or natural properties. During milling, the deterioration effect on its natural microstructure must be reced as far as possible, and the deformation between grains and grain groups must be reced, Most of the silicon powder (more than 99.8%) still keep the original natural microstructure. Among the four methods listed in Table 1, the best one is the impact rotation method. Because it uses the way of smashing the silicon block in the air, so that it can follow the weakest link in the body to break, and there is no structural deformation caused by squeezing, pressing and grinding
② specific surface area:
the surface area of powder is the surface area occupied by unit mass, with m2 / g as the unit. It is an important indicator of the ability to participate in chemical reactions. The specific surface area of silicon powder is larger, the reaction speed is faster, the reaction is more perfect, the utilization rate of silicon is higher, the fluidization state of reaction area is more ideal, and the silicon consumption rate is the lowest, which shows its high activity. Therefore, surface area has become an important index of silica powder activity. The specific surface areas of all kinds of powders are listed in Table 1, and the best one is the impact spinning powder< (3) particle size distribution:
the direct synthesis method is completed step by step in the fluidized state, the particle size of the material changes graally, the surface is constantly updated, the reaction is complete, and the unit consumption of silicon also decreases significantly. Therefore, in order to obtain the best effect, the particle size of silica fume should be combined with the size of silica fume. Therefore, the milling method must ensure that the particle size composition can be adjusted and the yield is higher. If the particle size of 1 t silicon powder is 0.1 mm ~ 0.4 mm, which accounts for more than 85%, it is the most suitable synthesis reaction. This is the raw material index of silicon powder used in a foreign 100 kt / a silicone coarse monomer fluidized bed< (4) surface protection:
in order to proce qualified finished silicon powder meeting the requirements of quality and particle index, the surface needs active protection. The principles are as follows: 1. It is concive to chemical reaction; 2; 2. It is beneficial to prevent combustion; 3. It is good for keeping loose and dry. The oxidation performance of silicon is very strong, especially in the state of fine powder. It can burn when encountering open fire in the air, generating silicon dioxide and releasing a lot of heat: Si + O2 → SiO2
therefore, two kinds of protection methods can be adopted: 1. Nitrogen protection, nitrogen circulation and continuous supplement of fresh N2 in the milling process, controlling the content of circulating N2 ≥ 93% and O2 ≤ 7%. 2. Under the atmospheric condition, in the closed system, the dry air and the raw silicon block enter the pulverizing system at the same time, and the quantitative feeding is carried out. The air and the broken silicon block form a micro negative pressure operation in the machine, and then the silicon powder is prepared, and the air is discharged without recycling. For example, silicon powder is taken by the impact spinning mechanism
in the storage, transportation and transportation of finished silicon powder, sealing, N2 sealing and N2 transportation are generally adopted, which are also effective measures to protect the activity of silicon powder. The final judgment of the surface activity of silicon powder is the proction practice, the effect of participating in the chemical reaction and the ability performance in the market competition. Of course, in order to obtain high activity, there is a problem of mastering the milling method, which needs a process of understanding and can stand the test of time
in the milling process of roller mill method, high energy consumption of N2 protection is needed, which can keep N2 ≤ 93% in the milling system, and N2 consumption per ton of proct & gt; 300 m3, because the temperature of circulating N2 in the pulverizing system rises to 60 ℃ ~ 70 ℃, which also contains 7% oxygen, it is inevitable that N2 and O2 on the surface of micro silicon powder. The steel consumption is about 0.15kg/t in the milling process. The steel consumption (iron powder) and the silicon powder easily adhered to the surface of fine silicon powder are dark black in appearance. The appearance of silicon powder prepared by impulse spinning without protection of N2 gas is bright. The temperature in the powder system is generally & lt; At 40 ℃, the steel consumption is mainly on the blade, and the steel consumption per ton of powder is about 0.1kg ~ 0.05kg. It can be seen that there is a big gap between the two proction methods in terms of manufacturing cost and different surface activity of silicon powder
conclusion:
1. The best quality (activity, particle size, chemical composition, etc.) of silicon powder should be selected
2. The milling method, safe, stable and environmental protection national standard should be selected for silicon milling
3. Silicon milling should choose the conditions of large single machine processing capacity and low cost
from the above three points, it is recommended to use the impact spinning machine to get silicon powder
