Rotary kiln tail gas cooler is a kind of equipment for heat exchange between 2 kinds of fluid medium with different temperature in mutual isolation. Different from other heat exchangers, the hot medium has higher temperature, lower density, higher flow rate and higher dust content, which brings some difficulties to design and manufacture.
A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: Cement; Lime; Refractories; Metakaolin; Titanium dioxide; Alumina; Vermiculite; Iron ore pellets; They are also used for roasting a wide variety of sulfide ores prior to metal extraction.
The clinker cooler, also known as grate cooler or cement cooler, it is a necessary equipment of cement clinker clinker cooler is mainly used to cool and transport the cement clinker. At the same time, cement cooler also provide hotair for rotary kiln and calciner, it is the main equipment of heat recovery for burning system.
However, new cement kilns are of the ''dry process'' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the preheater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln.
#0183;#32;The cement rotary kiln produced by Machinery has simple and solid structure, stable operation, convenient and reliable control of the production process, fewer quickwear parts, high quality of final products and high running rate, so that it is the equipment for cement plants to calcine high quality cement and it is also widely used in metallurgy, chemistry and construction industry.
#0183;#32;Some questions and answers of CEMENT ROTARY KILN News Date Due to reduced secondary air flow the heat recuperation in the clinker cooler might be affected for example with a higher secondary air temperature as well. The oxygen enrichment technology is established in some cement plants in order to improve production capacity. An
Rotary Kiln System (RKS) with a planetary cooler. The RKS at the Mbeya Cement Company (MCC) in Tanzania is used as a case study. The study investigated the eects of varying the RKS parameters against system behaviour, process operation, environment, and energy consumptions.
The cement production in the MCC plant is based on the dry process technology, and according to the preliminary energy audit, the thermal energy consumption in MCC is about per ton of produced clinker. The main source of energy in the plant is the coal that is obtained from Tanzania (Tancoal) and from Malawi (both, Mchenga and Erland).
A rotary cooler consists of a slightly inclined tube of similar construction to a rotary kiln, placed at a lower level than the kiln so that the clinker leaving the kiln can fall directly into the upper end of the cooler. Ambient air enters at the other end. The upper part of the cooler, because of the high temperature of the clinker, is brick
Rotary kiln installation forms a very complex system, as it consists of various components which affect cement production. However, some problems with particle settling are encountered during

production of cement rotary kiln with a cooler. ANALYSIS OF HEAT LOSS IN KILN IN CEMENT INDUSTRY A REVIEW The aim of this article is to improve the management of resources used in the cement production process and mitigate their environmental effects
Cement mill: cement ball mill, cement vertical mill, cement roller press, coal mill, Raymond mill (raw mill also available) Cement kiln : cement rotary kiln or shaft kiln Accessory equipment: cement dryer, grate cooler, preheater in cement plant, c onveyor, cement silo, and others.
Cement Kilns: Rotary Coolers. Rotary coolers for use with cement kilns. One way of shortening the cooler so that the second kiln pier need not be pierced was the quot;doublebackquot; or quot;concentricquot; cooler, produced by several manufacturers in the period later versions were frequently supplied with pressurisation air.
#0183;#32;The thermal efficiency of the rotary cooler can reach 5575% in dry cement production and 78% in wet cement production. But its heat loss is large, and the secondary air temperature is about 400750, which is not suitable for the large cement kilns.

Cement Production Line Rotary cooler is equipped with a cooling heat exchange tube the air/water flows inside the tube and the material flows outside the tube and the heat transfer through the tube wall surface achieves the
#0183;#32;The rotary kiln model dimensions have been setup according to a full scale 3000 t/d of cement with a total length of 60 m and inner diameter of m, except from the clinker sintering zone (the first 20 m from the burner end of the rotary kiln) where the coating thickness increases (100 mm) reducing the diameter to m.
offers 1,512 cooler of rotary kiln products. A wide variety of cooler of rotary kiln options are available to you, such as warranty of core components, local service location, and key selling points.
