A cooling grate, for cooling and transporting of cement clinker having at least one grate element with at least one support for cement clinker, having at least one cooling air channel discharging into the support which is inclined in conveying direction at least in a section adjacent to its outlet used to inject cooling air into the clinker has improved cooling characteristics if the cooling ...
♦ Middle air (grate cooler only) is extracted from the cooler roof if drying of process materials requires a temperature level which is higher than the waste air. If the quantity is small, up to 450°C can be expected at normal cooler operation. ♦ Waste air (grate cooler only) is also called cooler exit air or cooler .
Cement Production Process Flow Chart Cement Manufacturing Process,, flow chart of cement plant - SBM Mining Mass Flow Diagram of a Free-Standing Fertilizer Plant . ... 2015-7-28 · principle based model of grate cooler for cement plant. In this work, the temperature variation and assumptions of the model will be discussed. The model is ...
Grate Coolers 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

GRATE COOLERS / 3.1 The Reciprocating Grate Cooler / 3.1.4 Typical Grate Cooler Problems 3.1.4 Typical Grate Cooler Problems Most grate coolers show a tendency to one or more of the system inherent problems, and in many cases there is no real cure.
The grate cooler is divided into different sections. The hot part requires a heat-resistant lining withstanding the high chemical load. The colder part can be lined with standard materials like chamotte-based monolithics or bricks. Click on the 3D drawing below to learn more about the Calderys offering for the grate cooler.
In cement grate coolers, dense refractory linings backed by insulation materials often results in an unnecessarily heavy construction, which increases fuel expenditure. Furthermore, the lining can be at risk of alkali attacks, which increases maintenance costs.
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.
Jul 01, 2017· Applying grate cooler in the cement industry has provided the opportunity of heat recovery from hot clinker. In the current technology of clinker production processes, the thermal energy of clinker is used to preheat the combustion air, which is based on heuristic rules. However, in this study, the clinker production process (pyro-process unit ...
Cement manufacturing is a highly energy intensive process, ... clinker cooler, crushers, grinders, and materials-handling equipment. ... grate cooler, a tube (rotary) cooler, or a planetary cooler. It recovers up to 30% of kiln system heat and route it back to the
The aim of any cooling system is to cool the clinker as quickly as possible, to set and maximize C3S content. Simultaneously, it is important to capture and re-use the heat liberated by this process. In the grate cooler, the clinker enters at a temperature of around 1,200°C, rapidly spreading its heat into the grate and surrounding refractories.
The grate cooler in the cement industry utilize highly powerful fans which adds up to the huge initial capital investment (Hongyou et al., 2009). In fact, the major role fans play in modern cement operation cannot be overemphasized in the pyro process section most importantly it generates the cooling air for clinker cooling purpose ...
principle based model of grate cooler for cement plant. In this work, the temperature variation and assumptions of the model will be discussed. The model is developed for steady state condition. Variations of gas, solid temperature, wall temperature and heat losses through the wall are simulated ...
Energy Distribution of Grate Cooler. The tertiary air flow is used as a source of energy for heating kiln feed at the pre-calciner (Air flow rate for pulverized coal heating can be ignored as low volume required). The secondary air flow is required by the process system, which is high energy bearing air from the Kiln.
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 ...
May 17, 2012· moving grate plate from cooler. How to Build a HINGED HOOPHOUSE for a Raised Bed s, landscaped areas, patios, and walkways. Grate is made of solid brass and the collar is made of polyvinyl chloride, a type of plastic. The 4 in. Round Drain Grate has an open surface area of 5.3 sq. in. and flow rate of 16 GPM.
With over 800 clinker coolers commissioned around the world, Claudius Peters represents a leading role in the clinker cooling technology. Starting in the 1950's, Claudius Peters has gained almost 70 years of experience and has been responsible for many of the innovative milestones reached in the past decades that are considered today as state of the art in the cement industry.
In modern cement plants, the clinker cooler is the key to high recuperation effi ciency and low clinker outlet temperatures at the lowest possible energy consumption. + Compact design + Low power consumption + Effi cient clinker cooling The Pendulum Cooler® is designed as single grate with a roll crusher at the end or as double grate with ...
In a cement plant, grate cooler is a basic machine in the calcining cement system, its main function is to make the ripe cement material to next system. At the same time, the grate cooler could offer rotary kiln and decomposing furnace hot air flow, which is the main equipment for .
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
