1. PYNPUNT GEDREWE OPENING

Are you managing persistent bottlenecks in your cement production line that directly impact throughput and profitability? Vir aanlegbestuurders en ingenieurskontrakteurs, the challenges associated with clinker cooling often manifest as costly, recurring issues. Ervaar jy:
Oormatige energieverbruik: Inefficient coolers waste recovered heat, forcing kilns and preheaters to compensate, significantly increasing fuel costs.
Unpredictable Clinker Quality: Inconsistent cooling rates lead to variable clinker reactivity, compromising final cement strength and causing product variability.
High Maintenance Downtime: Traditional grate systems with mechanical complexity require frequent stoppages for grate plate replacement and drive system repairs.
Environmental Control Difficulties: Poor air distribution results in higherthannecessary secondary air temperatures or excessive dust emissions, challenging compliance.
Limited Capacity Flexibility: Aging cooler technology cannot adapt to changes in kiln output or clinker characteristics without sacrificing efficiency.

How do you select a clinker cooler that delivers operational stability, maximizes heat recovery, and provides a measurable return on investment?

2. PRODUK OORSIG

Die {{sleutelwoord}} is a highefficiency, reciprocating grate cooler engineered for the final stage of clinker production. It is designed to rapidly quench and stabilize cement clinker exiting the rotary kiln while optimizing thermal energy recovery. The operational workflow is defined by controlled, sequential steps:
1. Controlled Quenching: Warm klinker (up to 1400°C) is evenly distributed across the grate for an initial rapid temperature reduction.
2. Stratified Airflow: Highpressure fans deliver cooling air perpendicularly through the moving clinker bed in specific zones, ensuring efficient heat transfer.
3. Conditioned Transport: Reciprocating grates convey the material while continuously turning and mixing it for uniform exposure to cooling air.
4. Heat Recirculation: Hightemperature air from the hot zone is directed back to the kiln as secondary combustion air, improving kiln efficiency.
5. Finale verkoeling & Ontslag: Clinker is cooled to a safe handling temperature (typically below 100°C) before discharge to the conveyor system.

Toepassingsomvang & Beperkings: This equipment is core to all integrated cement plants with rotary kilns. Optimal performance requires consistent clinker granulometry; performance may be suboptimal with excessive fines or extreme variations in particle size distribution without specific grate adaptations.

6. TOEPASSINGSSCENARIO'S

Plant Capacity Upgrade Project

Challenge A midsized plant required a capacity increase from 3,200 TPD aan 4,200 TPD but was constrained by an outdated cooler causing bottlenecks and high maintenance costs every eight months.

Solution The existing cooler was replaced with a modular {{sleutelwoord}} designed for future expansion up to 5k TPD.

Results The retrofit achieved full design capacity within one month of commissioning. Secondary air temperature increased by over 120°C, contributing directly to a measured annual fuel saving of €280k ($300k). Maintenance intervals extended beyond two years.

Consistency Improvement Initiative

Challenge A producer faced inconsistent cement strength grades linked directly to variable final clinker temperatures ranging from 150°C due poor airflow control.

Solution Installation of a new {{sleutelwoord}} featuring advanced zoned airflow management controls was implemented during an annual shutdown.

Results Final cliker temperature stabilized at <65±10°C within three weeks of operation.The standard deviation of critical cement strength at day improved by over , reducing product quality claims significantly
