How to select the proper type of lime kiln
Selection of the type of lime kiln is very important, which is related to production efficiency, product quality and enterprise cost. The following are some key points for selecting the appropriate type of lime kiln.
Production scale shall be considered. If the production scale of the enterprise is large, the demand for lime output is high, and such large lime kiln as rotary kiln is more suitable, with large capacity, which can meet the demand of large-scale continuous production; If the production scale is small, the shaft kiln and other small and medium-sized kilns are more cost effective, and the investment and operation costs are relatively low.
Feed properties are key factors. The particle size and purity of different limestone raw materials are different. For the limestone with larger block size and harder texture, the shaft kiln may be more applicable; However, the rotary kiln has strong adaptability to raw materials and can handle limestone with various particle sizes and compositions.
Environmental requirements cannot be ignored. Nowadays, the environmental protection standard is becoming more and more strict. Select the lime kiln with advanced environmental protection technology, such as the kiln equipped with efficient dust removal, desulfurization and denitration devices, to reduce the emission of pollutants and avoid environmental risks.
Moreover, comprehensively evaluate the investment budget, post-maintenance cost and other factors, and select the type of lime kiln with the highest cost performance under the premise of meeting the production demand.
