Working Process:

Cement plant is composed of raw materials preparation, raw meal grinding, raw meal homogenization, clinker burning, cement mill grinding, packaging, delivery and so on. The cement equipment in the production line include: raw materials vertical roller mill, vertical coal mill, cement rotary kiln, cement ball mill, cyclone preheater and grate cooler, etc.

Configuration

Our Product Features:

Powerful Crush and Scientific Stockpiling

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

Scientific material piling and taking technology is used in the design of this production line  adopts to achieve the initial raw material homogenization. Thus the stock ground has the function of both storage and homogenization.

Low Energy Consumption in Grinding Process and 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  product quality assurance and energy consumption reduction by using high efficiency and energy-saving GRM series vertical roller mill to deal with all kinds of materials.

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 with 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 Process and Easy Operation

GRMK40.41 (2 + 2) cement vertical mill developed by our company is used on Clinker grinding equipment. It uses the exhaust stem of 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.
