Cement Preheater Cement Preheater is also namedprecalciner. Vertical preheater is one of the main equipments of active limestone. The main function is to send limestone materials sent by the upper part to the preheater body, while using the emitted high temperature gas after calcination, preheat the materials to about 900 evenly.

In the cement industry, suspension preheaters are a series of cyclones and duct vessels used to preheat raw meal. Temperatures progressively increase as the kiln feed moves towards the lower stages. Almost every suspension preheater includes a calciner vessel where additional fuel is burned to support the calcination process.
KHD built the firstPreheater(Germany, Bomke & Bleckmann), a starting point of a new aera of reducing the heat consumption of the clinker pyro-processing system by nearly 50% at this time. Today KHD is one of the technical leaders worldwide in this field. The raw meal processed in thekilnfirst passes through...

Using the latest developments onrefractory castable technology, Wahl has specially formulated monolithics for use in cement plant preheaters. They provide maximized resistance to alkali attack, along with optimized abrasion resistance and hot strengths.
A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln

India: ShreeCementhas completed the upgrade of apreheateron the clinker production line of Unit-I at its Beawarcementplant in Rajasthan. The clinker production capacity of the plant has now increased to 1.4Mt/yr from 1.1Mt/yr. Meanwhile thecementproducer has signed a memorandum of understanding with the government of Jharkhand to build a 2Mt/yrcementgrinding plant in Sarai Kale Karasawa.
Forcementproduction line, there are manycementequipments among whichcement preheateris included. Rotary kiln is used widelyin cementplant, and we design and produce new-style rotary kiln with verticalpreheaterwhich takes use of the heat of the flue gas coming out from the kiln end to preheat the dolomite to 800℃ in thepreheater.
Preheatersare used industrial dry kilncementproduction plants to heat the raw mix and drive off carbon dioxide and water before it is fed into the kiln. An analytical model of a generalized four-stage suspension cyclonepreheatersystem is presented.
WalFlow KLN60 is designed to withstand the highly alkali and abrasive environments foundin cement preheatertowers, including risers, feed shelves, and cyclones. This product also resists build up. WalFlow KLN60 is a 60% alumina mullite-based ultra-lowcement, self-flowing refractory castable.
The original rotarycementkilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated ...
