These are: planetary coolers, rotary coolers, grate coolers (both conventional and air-beam types), and cross-bar coolers. A. Planetary Coolers The planetary cooler served the cement industry for many years and was originally designed for wet process kilns with a high amount of secondary air available for the cooler.
coming out of rotary kilns. Heat transfer in coolers indirectly controls the performance of the rotary kiln and is therefore crucial in a cement industry. In this report, we present a computational model to capture heat transfer in grate coolers. The schematic of grate cooler considered in the present study is shown in Figure 2.

2. COOLER DESCRIPTION AND ASSUMPTIONS . The clinker going out of the rotary kiln at a temperature of 1380°C is cooled by the air at a temperature of 65°C (Fig.1) by a cross-flow heat exchange with the top of the highly refractory steel grate. Thanks to an oscillatory movement, the grates cause the advancement and the spreading out of the
gas from the rotary kiln and a klinker cooler, and an upper stage constructed as a calcining chamber having means for supplying raw dust or powder thereto, the calcining chamber having outlet means comprising a plurality of discharge channels. - Thus, in accordance with the invention, the riser pipeline from the rotary kiln to the heat exchanger is

Clinker Cooler. Clinker cooler is also called cement cooler, which set behind the cement kiln for clinker cooling. In cement plants, we usually adopt the rotary cooler and grate cooler for daily production. Inside the cooler, hot clinker will direct contact with the cooled air blown from the air blower to realize fast cooling.

Gambar 5. Rotary Cooler (Sumber: Dylan,Moore. 2011) Planetary dan rotary cooler memiliki batasan laju udara, biasanya 0,85 – 0,95 Nm3 /kg dari klinker, tergantung pada konsumsi bahan bakar dari kiln dan diatur oleh kiln ID fan. Untuk alasan ini, tempertur klinker melebihi 150 ºC dan digunakan injeksi air.
sekunder yang berasal dari clinker cooler dengan suhu sekitar 1200 – 1250 oC akan mengalami pendinginan lebih lanjut di dalam clinker cooler [2]. Sebagai media pendingin digunakan udara luar yang dihembuskan oleh 18 buah fan. Pada rotary kiln dibagi menjadi empat zona, yaitu: a) Zona kalsinasi (suhu 900 – 1000oC)
masuk ke rotary kiln yang bersuhu sekitar 14000C ini kemudian masuk ke unit cooler untuk pendinginan sehingga suhu klinker menjadi sekitar 1000C. Clinker (terak) dengan suhu tinggi
