Jun 29, 2018 In such systems, the grate plate supports were used to duct the cooling air directly to the grate plates and into the clinker bed. Depending upon the equipment supplier, the air beam was further subdivided across the width of the cooler such that only a few individual grate plates received air from a separate, controllable source
Silicon carbide or corundum low cement castables are the most suitable products for the application. 5.3.8 Clinker Impact In grate cooler kilns, when the burner pipe is positioned inside the kiln, past the nose ring, large lumps of clinker and coating constantly
Many of the grate coolers supplied for the cement industry over the last 50 years include hydraulic drives. Continuous developments for the clinker cooler hydraulic drive have achieved a
Specifications for the clinker cooler. Specific alloys are available for every area inside the clinker cooler. There is also a patented bar and clinker pocket grate. These are specially designed to fit on to the existing supports without needing to make any change to the fans or to the structure itself and give a better control of the dust
May 27, 2016 G- Coolers (from Claudius Peters) are effective in producing low temperature clinker in combination with a planetary cooler, a Iow-air-volume grate cooler, or to accommodate kiln capacity increase beyond the grate cooler capacity. Clinker, after the prima- ry cooler and clinker breaker, is allowed to settle slowly in a bed with heat exchange to
The grate cooler is of considerable importance in cement production and its heat distribution plays an important role in evaluating the energy utilization efficiency. In this study, we analyze the heat distribution in the entire grate cooler system of a 5000 t/d cement plant through experiments, and acquire the mass flow rates, inlet
The design of the Wave Grate reduces airflow resistance through the grate, which results in a significant reduction in pressure drop there by reduction in power consumption of cooler fans and efficient cooler operation. The upper Wave Grate with wear strips is the only wear part that needs replacement and has increased wear life
AGICO supplies 2 types of kiln cooler equipment for cement production line, one is grate cooler, the other is rotary cooler, grate cooler is more efficient in cement plant, rotary cooler is suitable for many other industries.Grate Cooler is a type of quench cooler. Its works by quenching clinker which is laid in levels on the grate plates with
The clinker-cooler is working constantly for your plant and preventative maintenance is vital to keep availability high. You need to avoid excessive wear on components, and have the right spare parts on hand for planned maintenance. ... Adjusting seal plates; Ensuring air tightness . ... Wave Grate for the SF™ Cross-Bar cooler Learn more
May 17, 2014 Experts, What standard do your companies use in the design of the structures that support belt conveyors? The structural verification itself isn't really an issue. The loads and load combinations, however, can create some interesting discussions. The belt conveyor isn't a building to be designed as per ASCE 7-05 or AISE Nr 13 and neither is a mobile machine to comply with ISO 5049
Fig 2.1: The Inner View of a Grate Cooler with Clinker Noddle on the Grate Plate. Source: (Ahamed et al., 2012) 2.2 Heat Transfer: There are three (3) modes of heat transfer involved in clinker cooling. They include conduction, convection and radiation. These heat movement modes are
Nov 28, 2016 The Air-Quenching shaking grate Clinker Cooler was developed more than 20 years ago as an improved heat recuperating cooler for use with rotary kilns. It was designed to air quench and cool large quantities of hot clinker rapidly, and to recover and return to the kiln a major portion of the heat from the clinker
Mar 01, 2009 Lafarge Zement therefore decided to install an IKN pendulum grate cooler. This cooler type with KIDS (clinker inlet distribution system) configuration as a fixed inlet followed by a continuous grate area ensures low agitation of the clinker along its transportation distance, even in the case of a high length to width ratio. The grate plates for
The cooler includes a fixed grate and at least two moving ones. Figure 1b shows a simplified graphic of a grate cooler. Due to their oscillating motion, the grates cause the solid material to flow forward and spread. After the final moving grate, clinker is first passed through a crusher and then transferred to the corresponding silo
Since the commissioning of the first KHD clinker cooler in 1936, ... grate plate design that offers a low pressure drop, this along with an improved inclination angle of 15 , increases ... • Easy to install and maintain. 11 wear protection The area beyond the static grate, at the beginning of the moving la
Nov 25, 2020 Fig. 2 shows the simplified two-dimensional grate cooler system in a 5000 t/d cement plant and the data acquisition position of the experimental system. The grate cooler operates as follows: The clinker from the rotary kiln falls on the stationary grate plate and is carried by the moving grate plate to move forward
Grate cooler Capacity: 1000-7000t/d Power: 22-30*2kw Applicable materials: Limestone cement clinker bauxite active lime and etc. Grate cooler is an important host equipment in clinker firing system of cement plant its main function is to cool and transport cement clinker and to provide hot air for rotary kiln and calciner which is the main equipment of heat recovery in firing system
Cement clinker cooler apparatus which includes a pair of grate type clinker coolers with opposite working directions. The hot clinker from the kiln is deposited on a distributor which directs the clinker in desired proportions to the two coolers. The distributor is adjustable to control the proportion of clinker supplied to each cooler
Summary: In the course of the rapid cooler development in recent years, new generations of grate coolers have come onto the market. In fact, it has meanwhile become difficult to keep track of the current cooler generation. However, despite the new market introductions, no great improvements have been made with regard to cooler efficiency and the cooling principle
