1. How much is a mobile mine earth rock separator? Presumably, this is a problem that most users are very concerned about. Due to its advanced and comprehensive performance, the starting price of this device is about 300000, which is not cheap,
2. Zhengzhou Hengyang instry is also good, good performance, welding close, thick material, quality is no problem, inspection under it.
3. 1. The importance of reasonable sand return quantity
generally speaking, the sand return quantity of spiral classifier is several times larger than the original feeding quantity, at least equal to 200% of the original feeding quantity, sometimes even as high as 600%. The reason why it is controlled to such a high level is that increasing the amount of return sand within a certain range can rece the over grinding and improve the proction capacity of the ball mill. However, the amount of sand return should not be too large, otherwise, the ball mill and classifier will be overloaded and the operation will be difficult. Especially when the amount of return sand is so large that the sum of it and the original ore feed exceeds the passing capacity of the ball mill, the ball mill will be blocked and unable to work normally. Therefore, in the closed-circuit grinding operation, in order to maintain stable proction and obtain good grinding effect, the return sand ratio must be controlled in an appropriate range
2. The relationship between the amount of returned sand and ore feed
when the grading overflow particle size remains constant, the amount of returned sand depends on the original ore feed to the ball mill. With the increase of ore feeding, the speed of materials passing through the ball mill is accelerated, and the discharge particle size becomes coarser, which increases the amount of sand return. On the contrary, the amount of sand return decreases, so a certain amount of ore feeding must have a certain amount of sand return. Therefore, by understanding the change of the amount of returned sand in the classifier, we can judge the change of the original feeding and other grinding conditions of the ball mill
3. Method for determining the amount of returned sand
through sampling and screening, the percentage of a specified particle size in the classifier feeding, overflow and returned sand is measured, and then the original feeding amount of ball mill is used to calculate according to the principle of material balance< 4. Calculation method of return sand volume
calculation principle of return sand ratio in concentrator α－ The yield of a given size fraction in ball mill discharge is%; β－ The yield of the above specified size fraction in the classifier overflow is%; ν－ The yield of the above specified size fraction in the classifier returned sand is%; C - sand return ratio. If the original feed rate of the mill is 100%, the overflow of the classifier is also 100%. According to the "material balance" formula: (100 + C) α= ν C＋100 β Therefore, the sand return ratio: C = [100] β－α/α－ν]× When 100% is calculated, it can be calculated according to the yield of indivial particle size or the cumulative yield. If the calculated results vary greatly according to different particle size, it may be that the sample is not representative enough, and it is necessary to take another sample for screening. When the difference between the calculated results is not large, the average value of C calculated by each grade is taken as the sand return ratio of the classifier.

Centrifugal separator is a kind of equipment which uses the principle of centrifugal force generated by solid suspension in high-speed rotation to make solid-liquid separation. The process of centrifugal sedimentation separation is complex, which is related to the factors of particle density, particle size distribution, concentration, solution characteristics and treatment process. However, the sedimentation characteristics of different livestock manure are very similar. Increasing the centrifugal acceleration can accelerate the sedimentation speed of solids in the manure
The horizontal screw centrifuge is a typical centrifuge, which was used to separate pig manure in the early 1970s. After years of improvement, the separation performance has been greatly improved. When the solid content of pig manure is 8%, the removal rate of total suspended solids can reach 60% The advantage of 
centrifugal separator is that the separation efficiency is higher than that of inclined plate screen, and the moisture content of solid after separation is relatively low. The main disadvantages of the typical horizontal screw centrifuge are expensive equipment, high energy consumption and difficult maintenance, so its popularization and application are limited
5. There is no such thing
6. 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.

7. The sand and stone separator mainly consists of six parts: feed tank, mixing separator, water supply system, screening system, slurry homogenization, recycling and waste slurry reuse system. When the resial concrete and water enter the material tank, the circulating water is continuously injected at the same time. Under the impact of water flow, the mixture slurry enters the separator with the water inlet to fully clean the resial concrete
the mechanical structure of the device is simple, and the environmental protection benefits are remarkable: the surface of separated sand is smooth, the ash content of sand is ≤ 1%, and the water content of sand is ≤ 3-5%; The car washing water is recycled, and the waste water reaches zero discharge; The equipment is wear-resistant, easy to operate, easy to clean and repair
the system is mainly composed of three parts, car washing platform, separator yard and pool. The car washing platform of a single parking space covers an area of about 40 square meters, the gravel yard covers an area of about 30 square meters, and the total area of the pool does not exceed 50 square meters, covering an area of about 130 square meters
there are single parking space, double parking space, concrete gravel separator and screw separator
Henan Libo sand and stone separator manufacturer has been working for more than 10 years, you can refer to it, and hope to help you! Hope to adopt! thank you!
