Project Overview
Project address: Zanjan, Iran
Project Name: 200tpd Activated Lime Calcination Equipment
Design scope of Zheng Mine: Design of process construction drawings for the entire factory
Zheng Kuang's supply scope:
(1) RS06 vertical preheater Φ 2.8 × 43m rotary kiln, LSF44 vertical cooler;
(2) Factory wide electrical, instrumentation, and automation control
The energy-saving lime rotary kiln has an advanced structure and stable operation. The use of a low-pressure vertical preheater can effectively improve the preheating effect, and the decomposition rate of preheated limestone before entering the kiln can reach 30%; Strong fuel adaptability, can use solid powder fuel, liquid fuel, and gas fuel; High activity of finished lime; This kiln type is widely used in the steel industry, chemical industry, and other industries.
The active lime calcination equipment is one of the core equipment of the lime production line, which has the advantages of simple structure, strong controllability, diverse fuels, energy efficiency, and large production capacity.
