Successful Practice Of high Efficiency Limestone Rotary Kiln Production Line With Daily Output Of 600 Tons

A building materials company in Guizhou is a leading supplier of building materials in the region, the market demand for high-quality lime products has increased dramatically, the customer’s original production line has been unable to meet the growing demand for orders, and there are problems such as high energy consumption, unstable product activity and so on. After much investigation, the customer finally chose Chunlei Machinery Manufacturing Co., Ltd, and we equipped it with a daily output of 600 tons of lime rotary kiln production line, to enhance the production capacity while realizing energy saving and improving product quality.

The Φ2.5×40 limestone rotary kiln adopts advanced kiln structure and refractory materials to ensure the uniformity of calcination and thermal efficiency. The cyclone preheater system can realize the pre-decomposition of raw materials and reduce energy consumption. Meanwhile, the intelligent control system realizes automatic monitoring and adjustment of the production process. The design of the whole production line takes into full consideration of the characteristics of raw materials and local climate conditions to ensure stable operation of 8-20 hours/day throughout the year. The project took only 6 months from design to commissioning, and quickly reached the designed capacity after commissioning. In more than a year of operation, the equipment has zero fault operation, and the main technical indicators far exceed the customer’s expectations.

Advantages of limestone rotary kiln:

• Product quality: the activity degree reaches more than 350ml, much higher than the industry standard
• Energy consumption performance: coal consumption 210kg/t lime, electricity consumption 45kWh/t lime
• Environmental protection index: dust emission <30mg/m³, NOx emission <200mg/m³
• Economic benefits: payback period of only 18 months, the new annual profit of more than 20 million yuan
• Intelligent temperature control system: kiln Intelligent temperature control system: the temperature control precision of the kiln reaches ±5℃, which ensures the stability of the products.
• Waste heat recovery: the preheater system recovers the heat of the exhaust gas, which reduces the coal consumption by 15%.
• Modularized design: it is convenient for the expansion of the production capacity and maintenance in the later stage.
