Бр нского трепела, содержащего 77,82 SI02; 4,21 ,1 2,44 Ре20з; 6,41 СаО; 0,55 МдО; 0,33 ЗОз; п.п.п. 5,01 и 3,0 мас.% (в пересчете на ЗОз) гипсового камн Новомосковского карьера, Тульской области, содержащего 1,47 SiOa; 0,04 А120з: 0,4 РеаОз; 30,60 СаО; 1,16 МдО; 40,5 ЗОз) и загружают в одну из камер двухкамерной лабораторной шаровой мельницы М-100. Во вторую камеру загружают аналогичную смесь без интенсификатора. Вес мелющих тел в обоих камерах и коэффициент их заполнени одинаков. Помол производ т в течение 45 мин. (Врем помола определ лось опытным путем до получени цемента не ниже стандартной тонкости). Тонкость помола определ ют по остатку на сите 008 и по величине удельной поверхности на при0sow and gypsum (clinker of the cement plant PO Volkovyskcement cement slate, containing, wt.%: elite 61.0; belita 14%, tricalcium aluminoferrite 13%; 15 wt.% is added. Brno tripoli, containing 77.82 SI02; 4 , 21, 1 2.44 Re203; 6.41 CaO; 0.55 MdO; 0.33 ZOz; p.p. 5.01 and 3.0 wt.% (In terms of ZOz) of gypsum stone of the Novomoskovsky quarry , Tula region, containing 1.47 SiOa; 0.04 A120s: 0.4 ReaO3; 30.60 CaO; 1.16 MdO; 40.5 ZOz) and loaded into one of the chambers of the M-100 two-chamber laboratory ball mill. A second mixture is loaded into the second chamber without an intensifier. The weight of the grinding media in both chambers and their fill factor are the same. Milling is carried out for 45 minutes. (The grinding time was determined empirically until cement was obtained not lower than the standard fineness). The grinding fineness is determined by the residue on sieve 008 and by the specific surface area at
боре ПСХ-2. Кроме того, полученные цементы исследовались на физико-механические свойства. Boron PSX-2. In addition, the resulting cements were investigated for physical and mechanical properties.
Остальные примеры выполнены аналогично примеру 1, отличаютс содержанием интенсификатора и сведены в таблицу.The remaining examples are carried out analogously to example 1, differ in the content of intensifier and are tabulated.
Из таблицы видно, что с введением предлагаемого интенсификатора возрастает производительность м.ельниц на 10-20% по сравнению с прототипом, увеличиваетс прочность в жущего на 30-50%.The table shows that with the introduction of the proposed intensifier increases the productivity of mills by 10-20% compared with the prototype, increases the strength of the cementitious by 30-50%.
