Description

Изв&стен епдаоб интенсификации то Еого размола клинкера, в многокамерных трубчатых мельницах путам ввода в них аспирационного воздуха. При тонком размоле клинкера наблюдаетс   вление агрег.-щии тонкодиснерсных частиц цемента и налинание их на мелющие тела и броневые плиты, что ионижает интенсификацию помола. Образование нлотных комочков объ сн етс  тем, что в процессе размола очень тонкие частиць материала зар жаютс  статическим электричеством и взаимНо прит гиБают-с  друг к другу.Izv & walls epdaob intensification that His grinding of clinker, in multi-chamber tube mills to put an aspiration air into them. At fine grinding of clinker, the aggregate-shchei of fine-displacement cement particles is observed and deposited on grinding media and armor plates, which ionizes the intensification of grinding. The formation of nodular lumps is due to the fact that during the grinding process very fine particles of material are charged with static electricity and mutually attract each other.

Описываемый способ позвол ет уменьшить  вление агрегадии и повысить интенсификацию тонкого размола. Это достигаетс  введением во все камеры мельницы , кроме лервой, увлажненного сжатого аспирационного воздуха.The described method allows to reduce the appearance of aggregation and increase the intensification of fine grinding. This is achieved by introducing into all the chambers of the mill, except for the first, moistened compressed aspiration air.

Обеспечение достаточно высокой интенсивности вентил ции мельницы св зано с необт одимостью установки в аспирационно системе мощных вентил торов дл  1греодо.теии  значительного гидравлического сопротивлени  междукамерных нерегородок.The provision of a sufficiently high intensity of the ventilation of the mill is connected with the need for installing powerful fans in the aspiration system for 1 year of considerable hydraulic resistance between inter-chamber non-enclosures.

Дл  снижени  гидравлического сопротивлени  междукамерных перегородок, согласно изобретению во все камеры, кроме первой, ввод т сжатый аслирациоиныи воздух через встроенные в междувамерные перегородки коллекторы с соплами Лавал , что разгружает вентил торы аснирационной системы и дает нозножность увеличить интенсивность вентил ции без повышени  мощности вентил торов .To reduce the hydraulic resistance of intercameral partitions, according to the invention, all cameras except the first introduce compressed asiraration and air through collectors with Laval nozzles built into interdigital partitions, which relieves the ventilation system of the ventilation system and gives an awareness to increase the ventilation intensity without increasing the fan power.

Увлажнение сжатого аспирационаото мздуха, во-первых, повышает электролрозодность его, что устран ет вредное 1.ти ние. статического электричества на процесс помола, но-вторых, понижа  температуру внутри камер мельницы, предотвращает дегидратацию двухводного гипса,  вл ющуюс  причиной выпуска нестандартного цемента.Humidification of compressed aspiration of aids, firstly, increases its electrodischarge, which eliminates harmful 1.thin. static electricity on the grinding process, but secondly, lowering the temperature inside the chambers of the mill, prevents the dehydration of two-water gypsum, which is the reason for the release of non-standard cement.

В результате введени  в мельницу Увлажненного сжатого аспирационного воздуха ее производительность повышаетс , примерно, на 10-15%.As a result of the introduction of a humidified compressed aspiration air into the mill, its productivity increases by approximately 10-15%.

Предмет изобретени Subject invention

Способ интенсификации тонкого размола клинкера в .многокамерных трубчатых мельницах путем ввода в них аспирационного воздуха, отличающийс  тем, что, с целью повышени  интенсификации размола, во все камеры мельницы , Кроме первой, ввод т увлажне нйй сжатый .аспирационный воздух.The method of intensifying the fine grinding of clinker in multi-chamber tube mills by introducing aspiration air into them, characterized in that, in order to increase the intensification of grinding, all the chambers of the mill, in addition to the first, introduce humidified compressed air.
