Classification of cenospheres and other ultra-light powder materials associated with a number of technological features. Since they are very light, the bulk density of about 0.1 m = 0, 5t/m3, the classification on the shakers and screens is rather time-consuming and not productive process, screens gradually become clogged and worn out due to the high hardness of cenospheres. The effective cell size on the screens of not less than 200-250 microns. And as cenospheres are very light and have a particle size of 60 microns to 500 microns - a sieve separation process can be highly effective. Another disadvantage of this method is the presence of shock loads on the thin wall tsenofer from which their destruction occurs.
Classification of cenospheres in the air stream also does not bring significant results, a large air velocity leads to the destruction of cenospheres, low - does not provide a quality product at the output, the output air stream must be cleaned of dust and debris cenospheres.
Offered by our firm decision to classify the cenospheres, perlite, vermiculite, and other similar powder materials is fundamentally different. Classification is determined by non-clogging
high performance sieves own production.
The output is a separation of several fractions of cenospheres: a large fraction - of more than 400 microns, the average fraction of more than 150 microns, the fine fraction is less than 150 microns, coarse and fine waste.
Energy costs on such equipment paltry compared to any other means of classification. Depreciation is so small, and non-stop operation of equipment can carry minimum costs. The wait staff does not require qualification.
Performance depends solely on the area and sieve can be any, but in some cases, performance is measured by volume.
