1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Managing the final stage of clinker cooling is a critical bottleneck with direct consequences for plant profitability. Inefficient clinker cooler operation leads to excessive heat loss, reducing thermal energy recovery for your preheater and calciner systems. Uncontrolled quenching can result in poor cement quality and increased wear on downstream equipment like crushers and conveyors. Frequent maintenance stops for refractory repair or grate replacement cause unplanned downtime, directly impacting your production tonnage and bottom line.

Are you facing high secondary air temperatures, inconsistent clinker bed permeability, or rising specific power consumption at your mill? Is your current cooler struggling with varying feed rates or producing clinker with residual heat that stresses material handling systems? The solution requires a system engineered not just to cool, but to optimize the entire thermal and mechanical chain.

2. APERÇU DU PRODUIT

Le Grate Clinker Cooler is a reciprocating, airpermeable bed system designed for efficient heat recovery and quenching of cement clinker exiting the rotary kiln. Its operational workflow is defined by controlled, staged cooling:

1. Controlled Infeed: Clinker chaud (approximately 12001400°C) from the kiln is evenly distributed across the cooler grate.
2. Staged Air Quenching: Highpressure cooling fans force ambient air upward through the moving grate and clinker bed in multiple zones, enabling precise temperature control.
3. Heat Recovery: The heated secondary air is directed back to the kiln combustion zone, while tertiary air is supplied to the calciner, significantly improving kiln system fuel efficiency.
4. Clinker Transport & Décharge: Reciprocating grates convey the cooled clinker (below 100°C + ambiant) to the discharge end for transfer to the cement mill.
5. Fines Handling: A dusttight casing and integrated drag chain conveyor manage cooler fines (grate spill).

Champ d'application: Ideal for medium to largecapacity dryprocess cement plants with rotary kilns. Limites: Performance is highly dependent on consistent clinker granulometry; not suitable for wet process plants or very lowcapacity operations without significant design modification.

3. CARACTÉRISTIQUES PRINCIPALES
