Rotary kiln -- the core equipment of enterprise production!

Rotary kiln Commonly known as rotary kiln, mainly for ore, concentrate, intermediate for sintering, roasting, etc.; rotary kiln types, because it is widely used in many industrial fields, and more and more important in these production, more and more become an important core equipment in enterprise production; in view of this, I will give you a detailed analysis of rotary kiln related equipment knowledge, analysis as follows.

 Rotary kiln

1、 Classification of rotary kiln

Rotary kilns are divided into variable diameter rotary kilns according to their shapes, and they can be divided into cement rotary kilns, metallurgical chemical kilns and lime kilns according to their different uses. Rotary cylinder equipment is widely used in rotary kilns for mechanical, physical or chemical treatment of solid materials. The development of different types of rotary kilns makes the rapid development of cement industry and makes greater contribution to the production of enterprises.

2、 Application of different types of rotary kiln

1. Cement rotary kiln

The main users of cement rotary kiln calcine cement clinker, which are divided into dry process and wet process cement kiln; wet process production is to add water into raw material mill, raw material is made into slurry with moisture content of 32% - 42%. The slurry meeting the requirements after homogenization is put into the kiln by kiln head feeder and calcined into raw material. The clinker out of the kiln is cooled by cooler and sent to clinker warehouse. Raw coal is dried and ground into pulverized coal before combustion It can supply heat needed for clinker calcination. Because raw meal is made into slurry, it has strong adaptability to heterogeneous raw materials, uniform raw material composition, stable process, high clinker fired, high clinker strength grade, less dust in grinding process and less fly ash at kiln tail; raw meal composition is even, so that the clinker is fired High, which is the main advantage of wet process production; dry process rotary kiln is the opposite of wet process rotary kiln. Dry process is to make raw material into dry powder with moisture content of only 1% or even less. Therefore, dry process rotary kiln has less heat required to evaporate water than wet process rotary kiln. Dry process rotary kiln production fluidity is worse than mud, raw material mixing is not very good, and composition is not uniform.

2. Metallurgical and chemical rotary kiln

The rotary kiln is mainly used for magnetization roasting of lean iron ore, oxidation roasting of chromium and nickel iron ore, roasting of chromium ore sand and chromium ore powder in chemical plant.

3. Limestone rotary kiln

Limestone rotary kiln, namely active lime kiln, is used to roast active lime and light burnt dolomite for iron and steel works and ferroalloy plants.

3、 Production advantages of rotary kiln Enterprises

1. In terms of environmental protection: some developed countries have used rotary kiln to incinerate hazardous waste and garbage for more than 20 years, which not only reduces the waste and makes it harmless, but also uses the waste as fuel to save coal powder and realize the recycling of waste.

2. In terms of production: in addition to calcining cement clinker, rotary kiln is also used for burning clay, limestone and slag drying; in the production of refractory materials, rotary kiln is used to calcine raw materials to stabilize its size, increase its strength, and produce high-quality finished products, which can be reprocessed,

3. Beneficiation process: the lean iron ore is magnetized and roasted in rotary kiln to change the original weak magnetism to strong magnetism, which is beneficial to magnetic separation.

No matter what kind of rotary kiln, Henan Hongxing manufacturers have production, price, far more than peer manufacturers, more knowledge of rotary kiln equipment, welcome to online free consultation, 24-hour online rotary kiln manager for your personal guidance.
