Maqolada Vanyukov pechi toshqollari bilan misning yo‘qotilish shakllari 2018–2026 yillarda e’lon qilingan eksperimental va sanoat ma’lumotlari asosida tahlil qilingan hamda shteyn tomchilarining toshqoldan cho‘kish sharoitlari hisoblab baholangan. Balxash zavodi Vanyukov pechi va shunga o‘xshash agregatlar toshqolida misning 75–90 % i mexanik shaklda, ya’ni muallaq shteyn tomchilarida bo‘lishi ko‘rsatilgan, biroq kremnezyom, glinozyom va magnetitga boy “Olmaliq KMK” AJ toshqoliga bu nisbatni to‘g‘ridan-to‘g‘ri ko‘chirib bo‘lmaydi. Erigan misning eng kam miqdori shteyndagi misning 65–70 % iga to‘g‘ri keladi, Al2O3 va CaO qo‘shimchalari uni yanada kamaytiradi. Adamar–Ribchinskiy tuzatmasi kiritilgan Stoks tenglamasi asosida 0,5 m qalinlikdagi toshqol qatlamidan 2 soatda cho‘kib ulguradigan tomchining kritik diametri qovushqoqlik 0,25–1,0 Pa·s bo‘lganda 123–240 mkm ekani aniqlangan. Qattiq magnetit miqdori 15 % gacha ortganda bu diametr yana taxminan 20 % ga kattalashadi. Sanoat toshqollarida tomchilarning 90 % i 15 mkm dan kichik bo‘lgani uchun ular 200 soatdan ortiq vaqtda ham cho‘kmaydi. Demak, “Olmaliq KMK” AJ Vanyukov pechi toshqolidagi misni kamaytirish uchun tindirish vaqtini uzaytirishdan ko‘ra magnetitni qaytarish, qovushqoqlikni pasaytirish va tomchilarni yiriklashtirish samaraliroq.
