The grate cooler is a type of clinker coolers, it plays an important role in the clinker manufacturing process. The grate cooler in a cement plant cools and transports the cement clinker from the rotary kiln, and provides heating air (secondary air) for the rotary kiln and preheater.The performance of the grate cooler will directly affect the production efficiency, energy consumption, and ...
The design of the cooler grate for the SF™ Cross-Bar® cooler and for the Multi-Movable Cross-Bar® cooler is in two parts and shaped like a wave. This means that the airflow is only deflected by 135 degrees, making it move in a wave pattern and reducing the internal flow resistance and thereby lowering the pressure drop.
Jul 21, 2021· Perhitungan heat loss didapat dari neraca massa dan neraca panas yang ada di grate cooler. Efisiensi grate cooler yang terukur adalah sebesar 95,73%. Kata kunci: Semen, grate cooler…
1 2. The SATAREM High Efficiency grate cooler is designed to overcome problems related to inadequate mechanical and/or process design from old coolers including: Poor heat recuperation, Red river, Frequent burns and damages on plates, Mechanical drives failures. Clinker outlet temperature higher than design, Insufficient cooling air or pressure.
Feb 25, 2015· Cooler adalah peralatan yang digunakan untuk mendinginkan material klinker setelah keluar dari kiln sebelum masuk ke tempat penyimpanan. Di Pabrik Semen Kupang 2, tipe Cooler yang digunakan adalah Grate Cooler. Gambar berikut ini menunjukan bagian dalam dari Grate cooler.
Raden Ayu. 1.1. Pengertian Heat Exchanger Sesuai dengan namanya, maka alat penukar kalor (heat exchanger) berfungsi mempertukarkan suhu antara dua fluida dengan melewati dua bidang batas. Bidang batas pada alat penukar kalor ini berupa pipa yang terbuat dari berbagai jenis logam sesuai dengan penggunaan dari alat tersebut.
Untuk mengoperasikan grate cooler secara optimal maka seluruh variabel yang mempengaruhi proses pendinginan klinker harus dapat diukur dan diatur setiap saat agar terkendali. Sistem pengendalian dari grate cooler dilakukan pada stasiun pengendali yang secara otomatis dapat mengukur atau mengetahui kondisi yang terjadi pada grate cooler.

PT. Semen Tonasa memiliki 8 unit pengantongan semen diluar pabrik yang berlokasi di Makassar, Bitung, Palu, Kendari, Samarinda, Banjarmasin, Bali, dan Ambon dengan Kapasitas masing-masing 300.000 metrik ton per tahun kecuali Makassar dan Bali yang berkapasitas 600.000 metrik ton semen pertahun dan Palu yang berkapasitas 175.000 metrik ton semen per tahun.
The Grate cooler is a quench cooler. After the clinker enters the cooling machine from the kiln, a layer of a certain thickness is laid on the slab, and the blasted cold air is quenched in the direction perpendicular to each other through the layer of the moving …
The grate cooler heat radiation was measured using infrared thermometer (561-566 nanometer wavelength). This compared the surface temperature to the surface area and values obtained were tabulated on Table 3.3. 3.2 Calculation Basis for Mass and Heat Balances. Basis for material: one (1) kg and 0℃ of clinker is usually taken as the basis. ...
The essential characteristic of a grate cooler is a layer of clinker spread on a more-or-less horizontal perforated grate, through which cold air is blown. The grate is made of steel, and the cold air keeps it sufficiently cool to avoid melting or burning. The clinker progresses through the cooler by moving more-or-less horizontally along the grate, and so the direction of the cooling air is ...
Grate Cooler: grate cooler is a kind of cement cooler that cools the clinker at a rapid rate. The temperature of clinker is reduced by cold air passing through the horizontally moving material layer from the bottom in a vertical direction. According to the movement of grate, grate coolers can be divided into rotary type, vibrating type, and ...
Dec 18, 2019· As an important process during the cement production, grate cooler plays significance roles on clinker cooling and waste heat recovery. In this paper, we measured experimentally the heat balance of the grate cooler, which provided initial operating parameters for optimization. Then, the grate cooler was simplified into a series-connected heat exchanger network by power flow method.
PYROSTEP® grate coolers can be installed on any kiln system.

Re: GRATE COOLER. Hello Afsal, What you are describing is a common problem in clinker coolers and is generally called a "Red River". I found this passage in a book called "Clinker Coolers" by Hans E. Steuch (Chapter 3.8, p494-495), which may be helpful to you;-
Proses pada tahap ini meliputi pemanasan awal umpan baku di preheater (pengeringan, dehidrasi dan dekomposisi), pembakaran di kiln (klinkerisasi) dan pendinginan di grate cooler (quenching). Selanjutnya klinker yang dihasilkan disimpan di clinker silo. Beberapa reaksi kimia yang berlangsung dalam proses pembuatan klinker yaitu: 1. proses ...
The grate cooler is integral to heat recovery from the clinker, so grate coolers that operate with higher efficiencies will lead to less wasted heat and reduce fuel usage elsewhere in the process. The grate coolers offer two main advantages. First, they can have a large capacity allowing large kiln capacities. Second, they offer efficient heat recovery by lowering the emperature of the clinker ...
