Abstract: The energy consumption of cement production in China is relatively high. How to expand the production capacity of cement with low energy consumption has become a more and more important problem for cement enterprises. Through the optimization of new dry process cement production technology and skills The paper puts forward the concrete measures to solve the shortcomings in the cement production system and put forward the concrete measures to improve the production efficiency of the enterprises.

 Energy saving calcining process and technical equipment of precalciner kiln

(1) With the growing scale of production, in order to meet the needs of the scale of the production line, developed a series of rotary kiln two support and the three support, three supporting the rotary kiln can meet the specifications of the largest scale production line about 6000t/d.

(2) Aiming at the combustion performance of anthracite with different properties, a series of burner products with flexible adjustment and adaptability are developed, so as to prolong the service life of the kiln skin.

(3) for anthracite, low calorific value coal, etc., a reliable and applicable calcining technology and equipment suitable for combustion characteristics has been developed, so as to give full play to the effective use of resources and reduce the operating costs of enterprises.

(4) In order to improve the efficiency of heat recovery, also developed the third generation of TC series air beam clinker grate cooler device, this device can be guessed the cooling air down to 1.7m3/kg, so as to ensure the effective operation of the burning system.

(5) In addition, developed a series of double and single series preheater system this system pressure loss in 4000Pa, by improving and optimizing the inner cylinder of a preheater, lock air valve and refractory materials, thus reducing the energy consumption of the clinker calcination, to ensure the reliable operation of the system.

(3)How to expand the production capacity of cement with low energy consumption ?
