| you are: manufacture Without waste air to exhaust
In CHSSR (at factory Chebin) "the know-how" komovoj is mastered and poroshkoobraznoj to exhaust, providing full use karbonatnogo raw materials (the author of system of NIISTROJMATE-RIALS, Brno). обои
Manufacture poroshkoobraznoj not slaked to exhaust it is carried out in cooperation with usual manufacture komovoj not slaked to exhaust in mine furnaces (at the given enterprise two furnaces working on coke on peresypnomu to a way). Mine furnaces use droblenyj limestone of a local open-cast mine with the size of pieces 7-18 прогнозы на футбол найти . smaller pieces of limestone see (mnee 7 sm) are exposed to the further crushing in molotkovoj a crusher, and then by air separation the product is divided on two fractions: more rough fraction of 0,2-2,5 mm is processed on izvest, and thin (less than 0,2 mm) are used for liming of sour soils. At air separation from thin fraction the clay substance and periklaz leaves, i.e. There is an enrichment okisju calcium of the limestone going on roasting. As a result poroshkoobraznaja not slaked izvest has high activity.
Manufacture not slaked to exhaust includes:
1) preliminary warming up of a powder of limestone to 700-800°С the gases departing from the rotating furnace;
2) roasting of the warmed-up powder in the short rotating furnace;
3) cooling after an exit from the furnace in sloevom a refrigerator. Despite the high expense of heat, manufacture of justifies because of complex full use of raw materials.
