Technical background
More and more high to the quality requirement of comminution of minerals matter, and require more and more accurate inspection and control.Therefore the task that the producer faces is all the time the production handling process of optimizing in building stones treatment plant, so that the quality of valuable product proportion and these products maximizes, reduce the waste product proportion that may accumulate simultaneously, or also it is further processed.
Compared with natural rubble, the stone that described comminution of minerals matter non-natural form, but the stone of for example pulverizing with manual type in stone pit.With without pulverize natural pebble and the difference of gravel aggregate be, the surface of comminution of minerals matter is not round and smooth, but has seamed edge and the plane of fracture.
If will carry out industrial deep processing to comminution of minerals matter, just need to be divided into various particle diameter grade.
For example can distinguish stone flour, Machine-made Sand, aggregate chips, rubble and rock ballast according to particle diameter.
Within the scope of Machine-made Sand (for example particle diameter 0 and 4 or 5mm between) often need to reduce being less than 0.09mm, being often also less than the proportion of filler of the material of 0.063mm usually used as particle diameter in Machine-made Sand, and make thus the quality of Machine-made Sand (coarse fodder) better.This process is called shedding by technical term.
Conventionally by sieving or the technology of sieving is carried out shedding.Using the feature of screening plant is that energy consumption is higher.According to task situation, the shedding of the technology of sieving needs the compass screen surface of corresponding size.In both cases, the characteristic of Machine-made Sand has a significant impact shedding quality.A very important influence factor is exactly water content.Too high water content can cause no longer can sieving, because no longer can utilize the air of lateral flow correspondingly to discharge fines.In the time that the employing technology of sieving is carried out shedding, if the water content of Machine-made Sand is too high, just have to increase the eyelet in compass screen surface, thereby this can cause again accurately separation mechanism sand also to cause sand loss to increase.
Although taking Machine-made Sand shedding as example has illustrated described problem, this problem is irrelevant with particle diameter in principle, even and other particle diameter or other input material, equally also there will be this problem.Therefore the utility model is not limited only to solve the problem occurring in the time of Machine-made Sand shedding, but relates in principle the problem existing in the time that polydispersity input material is separated into fines and coarse fodder.
