In 1977 - 1978, put in place the first and second processing line with a diameter of 6.4 rotary kilns / 7 m, 95 m long, in 1989, a third production line, complete with a rotary kiln with a diameter of 4.5 m and a length of 97.5 m with a reactor-calciner.
The design capacity of each kiln 3,000 tons of clinker per day. Feedstock shop is staffed by eight raw mill with a diameter of 4.2 m and a length of 10 m with the through-air-separators shop "grinding" is staffed by six cement mills with a diameter of 4.0 m and a length of 13.5 m
Portland cement production process consists of the following basic operations:
1.Dobycha raw materials and their delivery to the plant;
2.Droblenie, dosing and grinding of raw materials;
3. Preparation and updating of the raw mix;
4.Obzhig mixture (clinker)
5.Pomol clinker with additives (Preparation of cement).
Imported raw materials:-ash and slag, iron supplements. As additives to cement and gypsum used gliezh, also delivered from the side.
In 1996 the line was put into operation, "Haver" on the packaging of cement in bags, as well as equipment for loading bags into cars and cars packed with capacity of 250 thousand tons of cement per year.
In March 1998, was commissioned a second line of cement packing "Mellers," purchased by grant of the Japanese government., With a capacity of 250 thousand tons of packed cement.
The enterprise has mastered the production of oil-well cement used for oil and gas wells.
Localization program mastered the production of refractory fireclay products produced on the basis of local raw materials and used for their own needs, the design capacity of 2.5 million tons per year.
In January 2004, the plant was opened station for filling oxygen cylinders, which is used for its own needs and for the needs of other organizations working in the enterprise. Welcome to the website of Kyzylkumcement
Until 2005, the supply of potable and process water was made by CP, but starting in 2004 the construction of water pipeline for drinking water supply to the plant with water Damhodzhinskogo that featured January 2005. In 2005, construction began on the water main supply of process water from the river Zarafshan, which was put into operation in June 2006.
In September 2006, put into operation the third line for packaging of cement, "Mellers' capacity 250,000 t / y.
In order to provide the enterprise container for packing cement, in the city of Tashkent, the district Kibraj, 2006 was involved plant for the production of polypropylene bags.
