High-efficiency lime project in Luzon, Philippines
The intelligent lime production line of ZOOMJO GROUP gives us a head start in the Southeast Asian market! The whole line adopts modularized design, heat consumption is reduced by 22%, the activity degree is stable above 380mL, and the dust emission is only 6mg/m³, which is far beyond the Philippine DENR environmental protection standard

Production process
1. Intelligent raw material processing system
Three-dimensional warehousing: limestone (particle size 25-50mm) is sorted by three-dimensional laser scanning, impurity ores with magnesium content >2% are eliminated, and the purity is increased to 99%.
Pre-decomposition optimization: Qualified raw materials enter the five-stage preheater and are preheated to 850°C through 1100°C exhaust gas at the end of the kiln, with a decomposition rate of ≥30%, reducing the heat load in the kiln.
2. Low-carbon calcination process
Oxygen-enriched combustion technology: rotary kiln adopts biomass gas + pulverized coal dual-fuel system (substitution rate ≥ 20%), kiln temperature control precision ± 5 ℃, calcined belt temperature stabilized at 1250-1350 ℃.
Nano thermal Insulation Coating: Kiln surface temperature is reduced by 50℃, thermal efficiency is increased to 82%, and CO₂ emission per ton of product is reduced to 650kg.
3. Deep cooling and intelligent sorting
Grate cooler: cools the material to 65 degrees Celsius and discharges it from the cooler
Particle size control: After cooling the material through the laser particle size sorter, 0-5mm fine powder is used for the production of desulfurization agent, 5-40mm particles are used as raw materials for steel making, the resource utilization rate reaches 100%.
