Vertical Shaft Kiln Structures & Working Principles. In cement plants using vertical kilns, the grinded raw materials are first made into wet pellets by adding 12-14% water to the pelletizing pan of the disc pelletizer.Then the wet pellets are fed from the kiln top and discharged from the bottom after calcination.
Re: CLINKER FROM ROTARY OR VERTICAL SHAFT KILN. There are a number of reasons why the clinkers might differ, but buying clinker from a VSK would not be a completely wrong move. It would depend on the degree of combination of the clinker, the lime saturation and the silica modulus. There are at least 2 principle reasopns why the clinker from a ...

The patent was transferred in 1965 to Maerz Ofenbau AG in Zurich / Switzerland which then further developed the kiln process and the kiln design. 5.2.2 Operating principle Due to the conditions of parallel flow of the kiln charge and the combustion gases in the burning shaft the parallel flow regenerative kiln (PFR kiln) is perfectly suitable ...
Abstract. The calcination principle of composite firing shaft kiln is: mix the solid fuel (coke or anthracite) with qualified stone evenly, use rotary discharging device equipped on kiln roof to discharge the mixture into the kiln, then under its own gravity the mixture proceeds through preheating area, calcining area, cooling area, and finally calcined into qualified finished lime product.

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 ...

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.
A vertical shaft kiln is basically a moving bed reactor with the upward flow of hot combustion gases counter-current to the downward flow of limestone particles that undergo calcination at elevated temperatures usually above 900 °C. For a better understanding the kiln is divided in to three zones, namely the preheating, the calcination and the ...
