1. PAINPOINT DRIVEN OPENING

Are you facing persistent bottlenecks in your cement production line that erode profitability? For plant managers and engineering contractors, the clinker cooler is a critical yet problematic node. Common operational challenges include:
Excessive Clinker Outlet Temperature: Coolers failing to achieve optimal quenching can leave clinker at 250°C+, wasting recoverable heat, increasing downstream equipment stress, and risking conveyor belt damage.
High Specific Air Consumption: Inefficient air distribution and cooling grate design force higher fan power usage, directly escalating electrical costs by 1525% in the cooling phase.
Unplanned Downtime from Grate Failures: Premature wear of grate plates and components due to thermal shock and mechanical stress leads to frequent, costly maintenance shutdowns.
Poor Heat Recovery for Kiln/Calciner: Inconsistent clinker bed formation and air permeability reduces the quantity and quality of secondary combustion air, lowering overall kiln system efficiency.

Is your current equipment causing unpredictable operating costs and limiting plant throughput? The solution lies in selecting a highefficiency, ISOcertified clinker cooler engineered for reliability and maximum heat recuperation.

2. PRODUCT OVERVIEW

Our ISO 9001certified Horizontal Grate Clinker Cooler is engineered for modern dryprocess cement plants. It is designed to efficiently quench hot clinker from the rotary kiln, recover heat for combustion processes, and deliver cooled clinker to the conveying system.

Operational Workflow:
1. Controlled Feeding: Hot clinker (approx. 1400°C) from the kiln is evenly distributed across the full width of the reciprocating grate.
2. Stratified Cooling: A combination of undergrate fan chambers supplies controlled cooling air through the moving clinker bed. The "upandthrough" cooling principle ensures gradual temperature reduction.
3. Heat Recuperation: Hightemperature exhaust air (approx. 1000°C+) is directed to the kiln as secondary air; midtemperature air is used for fuel combustion in the calciner.
4. Final Cooling & Discharge: Clinker is cooled to within 65°C + ambient temperature before being discharged via a hydraulic grate drive system to the crusher and conveyor.

Application Scope & Limitations:
Scope: Ideal for new plant installations or retrofits in cement production lines from 2000 to 10,000+ TPD capacity. Suitable for a wide range of fuel types and clinker characteristics.
Limitations: Not designed for wet process kilns. Optimal performance requires consistent clinker granulometry; extreme variations may require precrusher integration.
