Complete set of equipment for lime kiln production and processing
Lime kiln is the core equipment for calcining limestone, widely used in industries such as metallurgy, building materials, and chemical engineering. The production and processing of its complete set of equipment involves multiple links such as raw material processing, calcination system, waste gas treatment, and automation control, and strict adherence to process standards is required to ensure product quality and energy efficiency.
Core equipment composition and processing points
Pre processing system: including crusher, screening machine and conveying equipment, requiring wear-resistant steel manufacturing to ensure uniform particle size of limestone (usually 30-80mm), and the crusher rotor needs high-frequency quenching treatment to extend its service life.
The choice of calcination host: vertical kiln or rotary kiln depends on the production capacity demand. The shaft kiln has a simple structure and is suitable for small and medium-sized production (50-300 tons per day). It is lined with refractory bricks; The rotary kiln has a higher production capacity (up to 2000 tons/day), and the cylinder body needs to be welded and annealed to eliminate stress.
Environmental protection module: The cyclone dust collector and desulfurization tower are key, and the stainless steel shell needs to be laser cut and accurately formed. The pressure for detecting the airtightness of the weld seam should not be less than 0.4MPa.
Process optimization direction
Modern lime kiln equipment tends towards intelligence, with PLC control of calcination temperature (± 5 ℃ error) and air volume, reducing coal consumption by more than 15%. During processing, large components such as rotary kiln gears require carburizing and quenching to achieve a hardness of HRC55-60, ensuring a 10-year replacement free period.
The processing of lime kiln equipment needs to take into account both material performance and process adaptability. It is recommended that users choose customized solutions based on the characteristics of raw materials, while paying attention to environmental protection and energy consumption indicators to comply with the trend of green production.
