Vertical Shaft Kiln When simplicity, lower capital investment and easy maintenance are the main issues, Vertical Shaft Kiln is the right option for the refractory. Numerous fuels such as coke, coal, gas, oil, as well as other alternative fuels are combusted using different types of burner or charging systems.
This operating principle is similar to that of a vertical shaft lime kiln. Cold air entering at the bottom cools down the descending (fired) bricks, is then used for firing, then warms up the still-cold bricks on top of the stack. Bricks are loaded at the top and removed at ground level in a continuous process (see animation below for details).
Shaft kiln, also known as vertical kiln, vertical shaft kiln, is a vertical and fixed clinker firing equipment.The raw meal ball with coal is fed into cement kiln from the kiln crown, and raw meal ball moves from top to bottom, air move from bottom to top. In fact, the physical and chemical changes of shaft kiln are similar to that of cement rotary kiln.
Although shaft kilns in different versions and sizes are used in a wide range of industries (lime, sugar, soda, iron & steel, etc.), what they have in common is that their refractory linings always consist of several layers. Usually, these consist of several insulating layers, the permanent lining, and the wear lining. Similarly, the zones in a ...
Aug 01, 2017· Research and development in lime shaft kiln design Research and development in lime shaft kiln design have a long history and many different economical and technical aspects have to be considered. 6.1 Requirements related to the calcining process In order to achieve a uniform product quality the retention time of each particle in the different ...
The next common type of kiln is the vertical shaft kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of vertical kilns over rotary kilns is the higher fuel ...
The shaft refers to a vertical vessel where the calcining takes place. Because of the weight of the bed of material in the shaft, there are limits on the size and strength of the type of limestone that can be calcined. Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating.
This is the first of two E2 150 tpd kilns in India, which are supported from Chememan Thailand. The plant is located in the SIPCOT industrial region of Tuticorin. This E2 Maerz 2-shaft lime kiln is coal fired and has a capacity of 150 tpd. Maerz supplied engineering and key equipment.
The vertical kiln manufactured by ZK group has the advantages, such as modern design, new technology, environmental protection,energy saving, higher machanization and automaticity etc. We offer 50 TPD to 300 TPD vertical shaft kiln on turnkey basis for cement and active lime plant, which is the advanced technology available world wide for small ...
Vertical Shaft Lime Kiln is a Thermal Equipment which is used for heating materials, like cement, copper Metallurgy, ferrous metallurgy, refractory material, chemical materials, paper making etc. Introduction. Lime is the high temperature product of the calcinations of limestone. Lime is manufacture in various types of kiln by one of the ...
The vertical shaft kiln is also known as the vertical kiln, is a vertical and static clinker firing equipment usually applied in the cement production line, lime production line, etc.
Refractories recommendation for vertical shaft lime kiln lining. A.Preheating zone. Limestone is heated from ambient to above 800 °C by direct contact with the gases leaving the calcining zone (i.e. products of combustion, excess air and CO2 from calcination). In this area, the working temperature is lower, but the lining brick needs to be ...

46 · Vertical Shaft Kilns. Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven ...
Vertical Shaft Kiln is known as the heart of the Cement Plant. Here the process of clinker formation takes place. BS Engineering design & manufacture different sizes of VSK from 50 TPD to 300 TPD. VSK is the only technology available world wide for small & medium entrepreneur.

Kilns to produce cement are almost equally old. Now cement kilns can be divided mainly into 2 types: vertical shaft kiln and rotary kiln. The vertical kiln is the older type and its origin dates back to the 5 th century AC. Rotary kilns were first used in 1880. Around the 20 th century, they replaced vertical shaft kilns almost everywhere.

A wide variety of vertical shaft kiln options are available to you, such as pakistan, none, and egypt. You can also choose from energy saving, high-accuracy, and long service life vertical shaft kiln, as well as from new vertical shaft kiln, and whether vertical shaft kiln is hotels, building material shops, or manufacturing plant.
Shaft kiln's small floor space. The vertical kiln is arranged upright. The single-hopper hoist is arranged at a large angle, and the functional areas are compactly arranged to greatly reduce the floor space. Shaft kiln's less investment. The kiln steel structure has fewer machining parts and lower processing costs.
Vertical shaft kiln is a kind of vertical cement kiln, the kiln body is upright on the ground and can not rotate. Materials in the kiln move from top to bottom, and the combustion-supporting air flows from bottom to top. The heat carried by the high-temperature materials will preheat the combustion-supporting air, which reduces the heat loss.
German Kiln Technology (GKT) is a major supplier of sintering lines and kilns for producing all kinds of technical ceramics, such as: For the firing process GKT offers the most diverse selection of equipment, dependant on capacity and procedure, operating electrically or with fossil fuels:
Vertical Lime shaft kiln is a fixed steel vessel kilns where the raw limestone of required sizes is fed from the top of the vertical lime kiln, from where it will move downward by gravity through all these zones known as the preheating, calcining, and cooling zones to become converted into fully burnt lime.
The three principle types are vertical shaft kilns, rotary kilns and periodic kilns. Vertical Shaft Kilns. As shown in Figure 1, a vertical shaft kiln is a refractory-lined tower fitted with peripheral fuel burners and air inlets in the lower section, and gas exhaust ports in the upper. Material to be processed is introduced at the top and ...
