Preheater In Cement Plant, Cyclone Preheater, Cement
The cyclone preheater, also called cement preheater, suspension preheater, is a kind of preheater in cement plant As the core equipment of dry method cement production line, cyclone preheater use suspension preheating to preheat and partly decompose the cementraw mix, shorten the length of rotary kiln, fully mix raw mix and hot air in the kiln, increase heat exchange rate, which promote the efficiency of rotary kiln plant and reduce the energy consumptionPreheater Building is one of the most vital parts of a cement plant where the raw meal is preheated using outlet hot gases of the kiln 5stage single string inline calciner system is used for this purpose Each stage of Preheater consists of fabricated cyclones and connecting gas riser ductsCement Plant Preheater Building TeklaCyclone preheater, also known as suspension preheater, is the main cement equipment commonly used in the new dry process cement production line It is the main gassolid reaction unit of the cement raw meal predecomposition Preheater In Cement Plant Cyclone Preheater
Cyclone Preheater in Cement Plant Suspension
The fivestage cyclone preheater we produce and supply is the most commonly used cyclone preheater in cement plants nowadays The fivestage cyclone preheater is composed of six cyclones in total One of the two cyclones at the top stage is thin and high, the purpose of this design is to improve the gassolid separation efficiency The basic characteristics of JY 5500T/D top cyclone preheater tube in structure are the adoption of 4core gradual spiral shell structure, the top center area is convex, the inner cylinder is long, The ratio of the inner cylinder diameter and the diameter of the cylinder segment is a little more than 1:2Cyclone preheater design for 5500 ton cement In traditional cement manufacturing technology, the preheater system is positioned before the rotary kiln in order to increase the heat transfer between the raw materials and hot gases Raw materials in the preheater are gradually dried, heated, and calcined by moving against the flow of the hot gases coming from the rotary kilnCFD simulation of the preheater cyclone of a cement
