Cement Rotary Kiln

rotary kiln description:

The rotary kiln refers to the rotation calcining kiln (known as rotary kiln), belonging to the building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. The Cement kiln is mainly used for calcining cement clinker, including dry and wet-producing cement kiln. The metallurgy chemical kiln is mainly used for lean iron ore magnetized roasting in steel plants of metallurgical industry; chromium and nickel iron ore oxidizing roasting; bauxite roasting in refractory plants and chamotte and aluminum hydroxide roasting in aluminium factory; chrome ore roasting in chemical plant. The lime kiln (i.e. active lime kiln) is used for roasting active lime and light burned dolomite for steel plants and ferroalloy works.

operating principle:

The rotary kiln is made up of gas flow, fuel burning, heat transfer, and material movement etc process. The rotary kiln is to make the fuel fully burning, the heat from which can be effectively pass to materials, so that material can produce series of physical and chemical changes after receiving the heat, finally forming finished product chamotte.

Technical parameter:

rotary kiln application:

The rotary kiln is mainly used for heating and calcining metallurgical, building materials, and ores etc mineral materials such as ceramsite sand, bauxite, limestone, cement, metal magnesium, alumina, hydroxide alumina, flyash , high aluminum refractory materials etc .

In cement plant, to produce cement need seven steps.

1. Crushing and Preblending

In cement plant, most of the material need to be broken, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material in cement production, after mining the size of limestone is large, with high hardness, so the limestone crushing plays a more important role in cement plant.

2. raw material preparation

In cement plant, producing each 1 ton of Portland cement need grinding at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum). Grinding operation consumes power about 60% of total power in cement plants, raw material grinding takes more than 30%, while coal mill used in cement palnt consumes 3%, cement grinding about 40%. So choosing the right grinding mills in cement plant is very important.

3. raw materials homogenization

Adopting the technology of homogenization could rationally get the best homo-effect and afford an eligible production to the demand

4. preheating and precalcing

Preheater and calciner is key equipment for precalcing production technique.

5. burning cement clinker in a rotary kiln.

The calcination of Rotary Kiln is a key step of cement production , it makes directly influence on the quality of cement clinker.

6. cement grinding

Cement grinding is used for grinding cement clinker (and gelling agent, performance tuning materials, etc.) to the appropriate size (in fineness, specific surface area, said), optimizing cement grain grading, increasing the hydration area, accelerating the hydration rate to meet the requirements of cement paste setting, hardening.

7. cement packing

Cement Plant equipments

In the cement manufacturing plant, not only the crushing machinery, but also the grinding machine is used as cement producing equipment.
