Cement production process - the broken and pre-equalization
1. broken process :
In cement production process, most of the raw material need to be broken, such as limestone, clay, iron ore and coal, limestone and cement production the largest amount of raw materials, after mining the larger particle size, high hardness, so the limestone plays an important role in the crushing of the broken cement plant materials.
Raw materials preblending the pre-equalization techniques is in the process of raw materials to deposit, withdraw, the use of scientific stacker-reclaimer technology, preliminary homogenization of raw materials, raw material yard along with the function of storage and homogenization.
2. Cement production process - the raw material preparation
During cement production process, producing tons of portland cement at least grind three tons of material (including a variety of raw materials, fuel, clinker, mixed materials, gypsum), according to statistics, the dry-process cement production lines grinding operations need to consume power accounts for about 60% of the power of the whole plant, which accounted for 30% of raw material grinding, coal grinding about 3%, cement grinding accounted for about 40%. Therefore, a reasonable choice of grinding equipment and process optimization of process parameters correct operation, control the operating system to ensure product quality, and reduce energy consumption is of great significance.
The cement rotary kiln is the key equipment in the production line
Rotary kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.
Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry, for calcimine of calotte and aluminum hydroxide in aluminum manufacturer,for claiming of chrome sand ore and chrome powder ore in chemical plant.
2.Rotary kiln with ISO9001 certificate
1.Advantage of reasonable structure
2. High efficiency rotary kiln
3. Low energy consumption
4. Easy Contral
5. Lime stone kiln
6. metallurgy kiln
7.Hematite limonite
8. Rotary calcination liln for lean iron ore
According to different material , the rotary kiln can be divided into :cement kiln, metallurgy kiln and limestone kiln. The cement kiln is mainly used for calcimine of cement clinker, there are dry and wet types. The metallurgy kiln is used in metallurgy industry and ironworks. for lean iron ore, chromium ore and ferronickel ore calcimine.
3.Cement production process - Preheat decomposition
Preheating and partial decomposition of the raw material from the preheater to complete, instead of some of the features of rotary kiln, that shorten the length of the kiln while the kiln to carry out the gas material heat transfer process in the accumulation of state, moved to the inner state of suspension preheater mixing of hot gas, which will make the raw material discharged with the kiln, increasing the contact area . The gas feed, the heat transfer speed, high heat exchange efficiency, to achieve greater production efficiency of the kiln system, to reduce the clinker heat consumption purpose.
