Role of Kiln Skin in Rotary Kiln

10/31/2022

Kiln Skin Is Made Of Clinker Or Dust From The Liquid Or Semi-Liquid Phase Into a Solid.

Its Main Functions Are

1. Protect the refractory bricks from direct high temperature and chemical erosion.
2. Store heat energy, reduce the heat loss from the kiln shell to the surrounding area, and improve the thermal efficiency of the rotary kiln.
3. Act as a heat transfer medium, absorbing heat by radiation or convection when the kiln shell is exposed to air and in contact with hot air, and transferring heat to the raw material by conduction when the kiln shell is in contact with the material in the lower part.
4. The surface of the kiln skin is rough, it can reduce the flow rate of powder and prolong the reaction time of material in the kiln.

$kinds of refractory bricks$

The chemical composition and structure of high-temperature glass bricks are the same as that of ordinary furnace linings. The chemical composition of refractory materials is mainly composed of silica (SiO2), Al2O3, SiO2, MgO2, Fe2O3, MgO, and MgO.
Aluminosilicate refractories are made of silica-based, sintered at high temperatures with an appropriate amount of alkaline molten liquid, and are heated and melted or mechanically ground to produce a sintered raw material or processed by a certain process.

Conditions Of Use Of Steel Fiber Castables
