Raw material cost control in lime production
The cost of raw materials for lime production accounts for a significant proportion of the total cost, and effective control is the key to enhancing enterprise profits and core competitiveness. To implement scientific cost control, it is necessary to start from multiple dimensions including the source, process, and technical management.
Source control, optimize procurement and quality
As the main raw material, strict quality standards should be established for the procurement of limestone to avoid high energy consuming and low-quality ores such as high sulfur and low calcium, and to improve output rate and reduce fuel consumption from the source. The procurement of fuels (such as coal and natural gas) requires close attention to market conditions, locking in high-quality and low-priced resources through long-term agreements and strategic reserves to mitigate price volatility risks. Meanwhile, actively evaluating and using alternative fuels with higher cost-effectiveness is an effective way to reduce costs.
Exquisite process, eliminating loss and waste
During the production process, it is necessary to strengthen the pretreatment of limestone by finely crushing and screening to ensure uniform particle size of the materials entering the kiln, thereby improving calcination efficiency and reducing fuel consumption per unit product. Establish a standardized warehousing management system to reduce the scattering and pulverization losses of limestone during stacking and transportation, while also ensuring the waterproof and moisture-proof management of fuel to ensure its stable calorific value.
Empowered by technology to achieve cost reduction and efficiency improvement
Cost control needs to rely on technological upgrades. Introducing advanced energy-saving kiln types and combustion technologies can significantly improve thermal efficiency. By using an intelligent control system to accurately control the air coal ratio, the optimal combustion conditions can be achieved. While ensuring the quality of lime, the consumption of raw materials and fuels can be minimized, achieving true cost reduction and efficiency improvement.
