1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Managing a cement plant’s core material handling and processing systems presents persistent challenges that directly impact your bottom line. ¿Estás experimentando:
Tiempo de inactividad excesivo: Unplanned stoppages in your preheater or kiln feed system due to equipment failure, costing upwards of $15,000 por hora en producción perdida.
Altos costos de mantenimiento: Frecuente, laborintensive maintenance cycles for cyclones, ducts, and coolers, consuming both spare parts budgets and valuable manhours.
Alimentación inconsistente & Calidad: Fluctuations in raw meal or clinker quality due to unreliable conveying or dosing equipment, leading to offspec product and thermal inefficiency.
Ineficiencia energética: Suboptimal heat transfer or excessive pressure drops in preheater towers and calciner strings, inflating your fuel and power costs per ton of clinker.
Rapid Wear & Reemplazo: Premature failure of critical components exposed to high temperatures and abrasive materials, forcing shorter replacement intervals.

La pregunta para los directores de planta es clara: how can you achieve greater operational stability, reduce total cost of ownership, and improve the predictability of your production line?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This product line encompasses customengineered Cement Plant Preheater & Calciner Systems. As an ODM manufacturer, we provide complete tower assemblies and key components designed for the pyroprocessing stage of cement manufacturing.

Flujo de trabajo operativo:
1. Raw Meal Introduction: Prehomogenized raw meal is fed into the topstage cyclone via a pneumatic or mechanical conveying system.
2. GasSolid Heat Exchange: The meal descends through a series of cyclones countercurrent to hot exhaust gases from the rotary kiln, undergoing progressive preheating.
3. Calcinación: In the integrated calciner vessel (inline or separateline), aproximadamente 9095% of calcination is achieved through efficient fuel combustion before the material enters the kiln.

Ámbito de aplicación: Suitable for new dryprocess cement line installations and major retrofits aimed at capacity increase or efficiency upgrades.
Limitaciones: System design is highly specific to plant capacity, fuel type, and raw material characteristics; not an offtheshelf solution.

6. ESCENARIOS DE APLICACIÓN

Capacity Expansion Retrofit Challenge A plant operating at 3,200 TPD needed to increase output by 25% without a new kiln. The existing preheater was a bottleneck.

Solution Engineering analysis led to a retrofit replacing the top two cyclone stages with our lowpressure drop designs and optimizing the calciner aerodynamics.

Results Achieved a sustained output of 4,000 TPD. The pressure drop reduction allowed the existing ID fan to handle increased gas flow without modification.

Alternative Fuel Integration Challenge A plant transitioning to higher rates of solid recovered fuel (SRF) experienced incomplete combustion and uneven calcination.

Solution Implementation of our multipoint burner array calciner system with dedicated SRF injection ports and enhanced mixing geometry.

Results Stable operation with >40% thermal substitution rate (TSR). Calcination degree at kiln inlet maintained consistently above 92%, improving kiln stability.
