Përshtatja e pajisjeve të fabrikës së çimentos ODM
1. HAPJE NGA PIKA E DIKIMIT
A po përballeni me pengesa të vazhdueshme në linjën tuaj të prodhimit të çimentos që gërryen rentabilitetin? Për menaxherët e impianteve dhe kontraktorët inxhinierikë, the clinker cooler is a critical yet problematic node. Sfidat e zakonshme operacionale përfshijnë:
Humbje e tepërt e rikuperimit të nxehtësisë: Inefficient cooling wastes thermal energy, increasing specific heat consumption by 1525 kcal/kgclinker and directly raising fuel costs.
High Clinker Outlet Temperature: Residual temperatures exceeding 100°C+ ambient strain downstream equipment like conveyor belts and elevators, accelerating wear and increasing maintenance frequency.
Inconsistent Cooling & Quality Degradation: Uneven air distribution creates "hot spots," leading to poor quenching that reduces cement strength (lower C3S formation) and can cause false set.
Kohë joproduktive me mirëmbajtje të lartë: Frequent refractory damage, grate plate failures, and highpressure fan issues lead to unplanned shutdowns, kushton mijëra në orë në prodhim të humbur.
Elevated Environmental Footprint: Poor combustion of recycled air results in higher secondary air temperatures at the kiln inlet and potential issues with NOx formation.
Is your current cooler system a source of variable cost and operational uncertainty? The solution lies not in offtheshelf machinery, por në personalizimin e inxhinierisë precize.
2. PËRMBLEDHJE E PRODUKTIT: ODM Grate Cooler for Cement Clinker
This product is a fully customized, heavyduty reciprocating grate cooler engineered for the efficient cooling of cement clinker from rotary kiln discharge temperatures (~1400°C) to a handling temperature below 100°C + ambienti.
Rrjedha e punës operative:
1. Clinker Distribution: Hot clinker from the kiln is evenly distributed across the full width of the static inlet grate via an adjustable weir plate.
2. Reciprocating Cooling: Hydraulically driven grate rows move reciprocally to transport clinker through multiple cooling zones (typically hot, intermediate, and final). Controlled undergrate compartmentalized fans supply cooling air.
3. Heat Recuperation: Hightemperature secondary air (8001200°C) is efficiently recovered at the kiln hood and directed back to the rotary kiln as combustion air.
4. Efficient Quenching & Transporti: As clinker moves, it is progressively cooled by forced air convection. Fully cooled clinker is discharged to the crusher and subsequent conveying system.
Fusha e Aplikimit & Kufizimet:
Fushëveprimi: Designed for integration into new dryprocess cement production lines or as a retrofit replacement for inefficient planetary or older grate coolers in plants with capacities from 1000 te 12,000 TPD.
Kufizimet: Performance is contingent on proper integration with kiln feed chemistry, consistent kiln operation, and adherence to prescribed maintenance schedules. Not suitable for wetprocess plants or alternative fuel operations without specific design adaptations.
