Jiangsu Haijian Co., Ltd.

 

 

 

lime rotary kiln

The rotary kiln produced by our company can be used in chemical, lime and other industries. After technological transformation, the rotary kiln sintering system equipment produced by our company adopts national advanced technologies such as high metering precession plunger pump, variable speed regulating valve, contact graphite block air seal and so on. In order to improve the degree of automation, the kiln head adopts an industrial TV to monitor the kiln, and an analog fluorescent screen is used to display the process flow; the sintering area adopts an infrared scanning system to directly reflect the combustion situation on the computer. Using these new technologies is intuitive, easy to operate, and reliable to use. Therefore, thermal conditions can be improved. Compared with the increase of 3~5%, the output is increased by 5~10%, and the heat consumption is reduced by 15%.

 

The lime chemical kiln is mainly used for the magnetization roasting of lean iron ore in iron and steel plants in the lime industry; the oxidation roasting of chromium and apatite; the roasting and smelting of gold ore in refractory factories and the roasting of clinker and aluminum hydroxide in aluminum manufacturers; the roasting of chromium ore and aluminum hydroxide in chemical plants. The same kind of chrome ore.

 

Structural features of lime rotary kiln:

  The kiln shell is made of rolled steel plate; its structure is optimized by computer software and has the characteristics of "vertical flexibility and horizontal rigidity", which improves the bearing capacity of the supporting device and the stability of the refractory lining, and the supporting roller bearing has a small width-diameter ratio L /D, higher reliability.

The transmission system adopts the special high starting torque motor for rotary kiln in the cement industry.

Labyrinth seals plus spring compression with additional asbestos insulation for higher applications, resulting in seal reliability and longer service life.

 

applicationrotary kiln:

 

1. Rotary kilns are often used in the production process of catalysts, molecular sieves, zinc oxide, etc. Therefore, rotary kilns can be found in various industries such as steel annealing, non-ferrous smelting, lime, and chemical industry. , and the construction industry.

 

2. Rotary kiln system, also known as rotary calcining kiln, is a commonly used building material machinery. According to the material properties, rotary kilns are divided into cement kilns, lime chemical kilns and lime kilns.

  

working principlerotary kiln:

  

1) There is a certain slope with the horizontal, the whole kiln body is supported by rollers and equipped with thrust rollers to control the up and down movement of the kiln body.

 

2) In addition to the main drive unit, the drive system is also equipped with an auxiliary drive unit to ensure that the kiln body can still rotate when the main motor is powered off and prevent the kiln body from being deformed.

  

3) The kiln head adopts a shell-type seal, and the kiln rear adopts an axial contact sealing device to ensure the reliability of the seal.

The whole process of active lime production

in the beginning

Limestone is a naturally occurring and abundant sedimentary rock composed of high levels of calcium and/or magnesium carbonate and/or dolomite (calcium and magnesium carbonate) and minerals. Lime production begins with the extraction of limestone from quarries and mines.

size. ..

The limestone goes to the primary crusher to break up the rock. Depending on the size of the feed required, the limestone may be passed through a secondary or tertiary crusher to further reduce its size. The stones are then sifted into a variety of sizes, from a few inches to dust-sized particles. Then wash the sized stone.

Calcined. . .

The processed stone is transported to the lime kiln by conveyor belt. To cook or "calcine" limestone, a large amount of heat must be transferred to the limestone. Generally speaking, the heat transfer from the fuel source to the limestone can be divided into three stages:

  • warm up– Limestone is heated by direct contact with off-gases entering the preheater kiln.
  • calcined– The kiln fuel is burned in preheated air from the cooling zone, and as the limestone moves down the kiln, the heat converts the limestone into quicklime and carbon dioxide (CO2).
  • cool down– The quicklime leaving the calcination zone is cooled by direct contact with "cooling air".

While there are several types of kilns in use, rotary kilns are the most common in the United States. A rotary kiln consists of a rotating cylinder placed horizontally on an inclined plane. Limestone is fed into the upper or rear end of the kiln, while fuel and combustion air are fired into the lower "front end" of the kiln. The limestone is heated as it travels down the kiln to the lower end. As the preheated limestone passes through the kiln, it is "calcined" into lime. Lime is discharged from the kiln into the cooler, where it is used to preheat the combustion air. Lime can be sold as-is or crushed to make ripe lime.

 

hydrated lime

Quicklime can be processed into slaked lime by crushing the quicklime, adding water to the crushed lime (water accounts for about 1% of the hydrate of the raw material), and then grading the slaked lime to ensure that it meets customer requirements for transportation.

Features

The main equipment of the cement grinding system is the roller press, the tube mill and the powder separator, which are the characteristic products developed by our company. In the 1980s, the company and Hefei Cement Industry Research Institute jointly developed the national "seven" key scientific and technological projectsth"Five-Year Plan" - After 20 years of manufacturing and improvement, the roller press is in a leading position in the country in terms of technology, production and service. It has good roll surface wear resistance, reliable hydraulic function, advanced automatic control system, its internal structure is becoming more and more reasonable, and its mechanical, testing and control technology is more scientific and rigorous. Has formed a large-scale professional series production. Using depolymerizer and V-type powder separator, the powder selection rate can reach 99%. After some cement plants use this equipment, electricity can be saved by 40-50%, output increased by 30-45%, and benefits and profits have increased significantly. Therefore, this equipment is the best choice for a better cement grinding system to reduce energy and resource costs and increase production. The main specifications are 1000×30, 1600×1400

Wait for ten. Up to now, nearly 500 sets of this type of equipment have been sold, occupying an important share in the domestic market. With the structural adjustment of my country's cement industry, scale and energy saving are the general trend. Therefore, the company attaches great importance to the development of large-scale tube mills and powder separators, and now has the ability to design and produce 4.8×13m, 3.2×13m and other tube mills. In 2007, started to produce 20 sets of mills from POLYSIUS company, such as 3.0m, 3.4m, 3.8m, 4.2m, 4.4m
