Model Number: grate cooler Brand Name: CHMM Key Specifications/Special Features: BriefA grate cooler is the main cooling equipment in cement production system, and it’s used in cooling the high temperature clinker from rotary kiln to the temperature that the next conveyor, storage and cement mill can bear, meanwhile gather the high heat of hot clinker for rotary kiln and thermal decomposition furnace, it increases the heat efficient and clinker quality.Working principleHigh-temperature clinker fall on the stage grate bed from the kiln inlet, at first the material will be sharp quenched by the high-pressure blower of the stage grate bed, then slide to the standard block under wind and gravity, and uniformly distribute on the grate bed under the push of the scraper, which reciprocate swings, form a certain thickness material, which moves forward to the outlet slowly under the push of the scraper of the grate cooler. A kibbler roll for clinker mounted at the discharge end of the grate cooler, the fine clinker (less than 20mm) leaks directly from the gap of the rollers to the clinker conveyor, for the large clinker,after grinded and falls to the clinker conveyor then sent to storage. Each array blocking below forms an air chamber, one blower to be used for supplying cold air, which is blowed to the material layer through grate plate, to make the clinker cool completely. The high-heat combustion air from cooling clinker enter the kiln and decomposing furnace, the remained heated air can be used for cogeneration and coal mill drying, the heated air at lower-heat section will be exhausted into atmosphere after treated.
