Limestone is a common non-metallic mineral, widely used in construction materials and industrial raw materials. Limestone can be directly processed into powder or calcined into quicklime. In industry, quicklime can be mixed with clay, etc., after high-temperature calcination and cement ball mill grinding to make cement; in steelmaking, active lime is the best auxiliary material; The finished product formed by crushing and grinding limestone is widely used in artificial flooring, rubber, plastics, papermaking and other industries. This article mainly introduces these two processes.
1. Lime Rotary Kiln Calcination
The material will be fed into the kiln tail through the chute in the gas chamber. As the kiln shell is inclined and rotates slightly, material will move along the round shell and move along shaft direction from kiln tail to kiln head. The material will be processed through pre-heat, decompose, calcined and will be fed into a cooler. Fuel will be given through gas or coal burner at kiln head and will be combusted in the kiln. Heat will be transferred to material by fire radiate, hot air flow, kiln brick transfer and make its final product.
2. Dry Production
First, remove the gangue in the original limestone raw material, then use a limestone crusher for coarse crushing, and then use a vertical roller mill for grinding, and the products that meet the particle size requirements are packaged and stored.
CHAENG can provide lime rotary kilns, limestone crushers, vertical roller mills, etc. to process limestone in different processes. If you have any questions or needs about limestone processing, please feel free to consult online or leave a message.
