100,000 TPY Hydrated Lime Production Line in Guangxi

Project Overview

Relying on local mineral resources, a large calcium enterprise in Guangxi invested in a full-process hydrated lime production line. After comprehensive evaluation, the customer adopted the GK calcium hydroxide production line equipment from Guilin Mining Machinery. Adopting the advanced process of "vertical kiln calcination + two-stage slaking + fine grinding", this line can stably produce 325-mesh hydrated lime powder with an output up to 15 t/h.

Project Details

Large limestone lumps are coarsely crushed by a jaw crusher and then classified and screened by a vibrating screen to ensure uniform feed size for the kiln. The new energy-saving and environment-friendly steel mechanical vertical kiln preheats materials with waste flue gas waste heat, effectively cutting coal consumption. The automatic control system precisely regulates calcination temperature and holding time to guarantee that the produced quicklime meets high-activity industrial standards.

The calcined quicklime is fed into the GK lime slaker. Precise control of water-lime ratio and slaking temperature achieves efficient slaking. The preliminarily slaked hydrated lime goes into the two-stage slaking system for sufficient curing and deep slaking to reach industrial-grade hydrated lime standards.

Slaked hydrated lime enters the GK lime mill for fine grinding. The ground hydrated lime powder is precisely classified by a classifier to separate fine hydrated lime powder meeting the 325-mesh fineness requirement. Unqualified coarse hydrated lime powder is returned for regrinding. The collection system captures dust throughout the whole process to ensure clean production, and finally high-activity finished hydrated lime powder is obtained.

Project Advantages

Deep Slaking: The energy-saving steel mechanical vertical kiln ensures high activity of quicklime, and the two-stage slaking system realizes efficient and deep conversion.

Energy Saving & Eco-friendly: The core calcination equipment adopts a nationally recommended furnace type. It preheats raw materials by utilizing flue gas waste heat to greatly reduce coal consumption. The whole line is equipped with high-efficiency dust removal systems to achieve ultra-low emissions and comply with clean production standards.

Intelligent Control: The production line adopts an advanced Distributed Control System (DCS) to centrally monitor the whole process including crushing, calcination, slaking, grinding and dust collection.
