- specific consumption of electricity for milling of Portland cement clinker in a centrifugal-impact mill is 12-18% lower than that of a ball mill;
- the concrete mixes based on cements of centrifugal-impact milling are characterized by lesser water requirement (by 4-6 l/m3) and by lesser cement consumption (by 7-13 kg/m3);
- there is a possibility for centrifugal-impact mills to regulate the size of particles of the obtained product.
The technology to obtain mixed Portland blast-furnace ce-ments (Pbfc) is developed by Spa «Center» specialists, too. The per-formed tests on Pbfc in hard concretes of classes В 12,5 и В 7,5 showed that the concretes have standard physical & mechanical and operational characteristics. The proposed technology makes it possi-ble to reduce significantly the cost price of produced material.
