Based on the multi-phase system analysis, we determined general pneumatic separation regularities of the dried crushed target product and detected the main interrelationships between physical and chemical effects and phenomena that takes an important place in the process of pneumatic separation with simultaneous crushing of the target product (calcium carbonate) of chalk in bulk materials and on this basis identifies the possibilities of the pneumatic separation process in the flowing fluidized volume, and proposes rational methods for intensifying the process. The principal device here is the fluidized volume moving unit. The fluidized length, the fluidized layering zone and the inlet area. The volume zone that is fluidized is divided into two components: the gas phase and the solid phase. The solid phase, in turn, consists of the first, second, third crushed target product particles, etc. components.

Ushbu ishda kop bosqichli, tizimli tahlil yordamida yirik, mayda-butun mahsulotlar pnevmo separatsiya qonuniyati korib chiqildi hamda karbonat kalciy ya'ni bor mahsulotining pnevmo  separatsiyasi yordamida hosil boladigan fizik-kimyoviy effekti va hodisalarning bogliqligi aniqlangan.Ushbu jarayonlaning asosini chala kuydirilgan hajmli mahsulotninng aralashmasidir.Modellashtirishda chala kuydirilgan zona 1 ya'ni, gazli va qattiq fazalardan qismlardan ekanligi aniqlangan. Modellashtirish jarayonida raqamli ekranda hisobotlar, vaqtinchalik grafiklar orqali namayon bolishi kuzatildi.Grafiklar shuni korsatadiki umumiy massa ichidagi maydalangan mahsulotlar koncentratsiyasi ma'lum bir intervalda togri chiziqda ya'ni to'yingan holatda bolar ekan. Tajriba shuni korsatadiki, yuqori sifatli maydalangan mahsulotlarni olish nazarda tutilgan.

В статьена основе многоступенчатого системного анализа отражены общие закономерности пневмосепарации сушенного измельченного целевого продукта и выявлены основные взаимосвязи  физико-химических эффектов и явлений, имеющих важное место при протекании процессапневмосепарации с одновременным измельчением целевого продукта– мела(карбоната кальция)  в сыпучих материалах и на этой основе определены возможности процесса пневмосепарации в фонтанирующем псевдоожиженном объеме, а также предложены рациональные пути интенсификации режимов   функционирования  процесса пневмосепарации с одновременным измельчением целевого продукта в фонтанирующем псевдоожиженном объеме. Основным объектам исследования здесь является аппарат с фонтанирующим псевдоожиженным объемом, имеющим зону псевдоожижения и зону уноса. Зона псевдоожижения разделяется на две составляющие: газовая и твердая фазы. В свою очередь, твердая фаза состоит из частиц первого, второго, третьего измельченного целевого продукта и др. компонентов
