The new dry process cement production line with capacity of 1500t/d built by Xinxiang Great Wall Machinery Co., Ltd. adopts scientific production technology on design and new advanced equipment, in order to improve the equipment level of the production line and ensure the realization of design index.

Features:

　　Powerful Crush, Scientific Stockpiling

　　The new dry process cement production line with capacity of 1500t/d, build by our company, is rationally equipped with advanced equipment for grinding the majority of raw materials. The limestone crushing uses TKPC16.18 single-section hammer crusher, whose feeding size is 800 mm, production capacity is 250 t/h, and annual utilization rate is 25.51%.

　　This production line design adopts scientific material piling and taking technology, to achieve the initial raw material homogenization. Thus the stock ground has the function of both storage and homogenization.

　　Low Energy Consumption in Grinding, Reasonable Homogenization

　　The energy consumption in cement grinding process accounts for more than 60% of the whole production line, therefore, it has great significance in ensuring product quality and reducing energy consumption by using high efficiency and energy saving GRM series vertical roller mill to deal with all kinds of material.

　　The line is equipped with φ15×50mMF homogenization silo which integrates raw meal storage and homogenization. The raw material reserve is 6500 t, with 2.86 d storage life.

　　Preheating before Calcination, High Efficiency and Energy Saving

　　Raw materials are sent into φ3.5×54m rotary kiln to be calcined after preheating and precalcining in the cyclone preheater. That is conducive to improve the production efficiency of kiln system, shorten rotary kiln length, and reduce the heat consumption of clinker calcining.

　　Energy Saving in Grinding, Easy Operation

　　Clinker grinding equipment uses GRMK40.41 (2 + 2) cement vertical mill developed by our company. It makes use of exhaust stem from preheater outlet (300-330) as the drying heat source. Cement vertical roller mill has the characteristics of simple technological process, safe and reliable operation, high grinding efficiency, low power consumption, less maintenance, and short debugging cycle, etc.
