How to raise the efficiency of a mill?
    Practically in any branch mills are applied to crushing. Crushing - one of the most widespread and demanded operations in any industry. It is possible to present easily, what processes go at beating of the various raw materials, one kinds are very easily grinded, others it is heavier, the third in general are strong abrasives, the fourth there and then stick together and turn to porridge. Therefore under various raw materials it is manufactured and the equipment for beating is issued various according to the destination. But what overall performance of this equipment?

Let's assume (and so it and is), that you need to grinde any material to particle sizes 20 microns, that is the great bulk of particles should be no more, as a result, you receive the most part from all received material with a degree of fineness 10 microns, and the essential part of the received powder will have particle size from 0,1 to 5 microns. It is a so-called dust. And presence of this dust in a mill only COMPLICATES beating of larger particles, therefore expenses for crushing start to grow exponentially, the beating, the above an expense and time for achievement of a demanded degree of fineness of beating is more thin.

Moreover, dust presence in many cases extremely is not desirable and it is frequent very strongly complicates not only crushing process, but also forces to position additional extracts, ventilation etc. Thus in the world practically there are no systems of a filtration, capable to detain a dust dimension less than 3 microns. Thus heterogeneity of the received powdery product is highest.


The question arises and what to do? To classify? The answer yes, but not standard qualifiers.


Our decision is maximally simple and effective. Replacement of your mill equipment thus is not required. We suggest to make production of crushing of more effective in times!

The sequence looks as follows: let there is a continuous beating in your mill in rather sparing mode, further the received product enters at once in EMC where there is its classification by the particle size necessary to you, the fraction which satisfies you, enters in the bunker and-or in the further production, and large particles enter revertively on the further crushing in a mill. That is small particles almost leave at once from a mill and do not stir to process. Thus we receive maximally effective cycle and crushing process.


The yielded technology possesses a number of conclusive advantages:


Minimum of expenses for the electric power on a maximum of the grinded product

Minimum loading on the equipment

The minimised deterioration of the mill equipment

Necessary particle size of a grinded product

More high efficiency for a time unit

Dedusting of the received powder (if it is necessary)


All it is possible only thanks to a new class of the equipment for separation of dry powders with particle sizes up to nanometres a range, developed and supplied only our firm - EMC. The yielded class of the equipment is well scaled.



We have not found equipment for classification of powders by a dry process, having the technological parametres comparable to what we have reached on EMC, therefore we consider our classifier as the best in the world.
