The rotary cement kiln is the most vital device in a cement plant, it is the place where the raw meal is burnt and calcined into clinker. Cement rotary kiln plays a variety of roles in the cement production line at the same time. It is not only a combustion device, but also a heat exchange device, a chemical reactor, and a conveying device.
However, due to the homogeneous composition of the slurry raw meal, the clinker calcined in the wet method rotary kiln usually has high quality, high strength grade and less dust pollution. Cement Rotary Kiln AGICO Under normal circumstances, the body of cement rotary kiln is placed horizontally and inclined to a certain angle with the ground.
Lime rotary kiln for sale! AGICO CEMENT is a rotary kiln manufacturer that supplies rotary kiln for various applications, tph production capacity available, EPC solution for
Working principle of cement rotary kiln During working of cement rotary kiln, pulverized coal (natural gas) is burned in the cement rotary kiln to generate heat. The heat is used to heat the material by gas conduction or radiation. At the same time, as the kiln body rotates according to the designed

Rapid cooling of clinker can mitigate the expansion problems, however higher MgO causes ball formation in kiln, increases melt phase etc. and therefore, can disturb kiln operation. Alkalies A part of alkalies Na 2 O and K 2 O combines chemically with clinker minerals, while as the major part remains as water soluble and affects adversely cement strength (28 Day Strength).

Cement kiln is used to calcine cement clinker in the cement plant, also known as cement plant kiln. Like we all know, cement production line include three main steps: preparation of cement raw materials, clinker production, and finished cement production. As a core cement equipment of clinker production, cement kiln is applicable for various materials, such as limestone, clay, dolomite, bauxite, etc.
Manufacturing the cement kiln Wet process kilns. The original rotary cement kilns were called ''wet process'' kilns. In their basic form they were... Dry process kilns. In a modern works, the blended raw material enters the kiln via the preheater tower. Here, hot gases... The clinker cooler. There
In 1987, Hurry and Seaman in the USA developed the first successfully working rotary kiln to produce cement clinker. The first rotary cement kilns were using the wet process with one very long kiln tube, making it the dominating single piece of equipment of a plant.
Many cement plants use bituminous coal as the fuel of rotary kiln, so the ash content, volatile matter, calorific value, fineness and moisture of coal fines will affect the clinker calcination process in the kiln.
In the rotary kiln, the carbonate is further rapidly precalcined and a series of solid phase reactions occur to form minerals in the cement clinker. As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker).
The rotary kiln cement plant can be divided into dry method cement plant and wet method cement plant. Their main difference lies in the cement rotary kiln. Raw meal calcined in the wet method kiln is a slurry containing 32% to 40% moisture, so the kiln body is longer and the clinker produced is of high quality with small dust pollution.
The table below contains an alphabetical list of plants that have made clinker since 1895. Plants with rotary kilns are in list is believed to be complete. The table contains links to descriptions of the individual plants. As of 28 August 2011 all these descriptions are in place, although many are still significantly deficient.
Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials equipment category. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. Cement kilns are mainly used for calcination of cement clinker, divided into two categories:
Cement rotary kiln: cement rotary kiln is a laterally set cement kiln that inclined to a certain angle with the ground. Raw meals in the kiln body will be calcinated in a lowspeed rotation. In present cement plants, the new dry process cement rotary kiln is the most widely used.
