Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process. Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size.
Abstract: Cement-kiln dusts from rotary kilns in the production of portland cement may be an important source of K for plants. The dusts contain approximately 9% K2O (70% soluble in HjO, the rest soluble in 2% citric acid) and can be enriched by adding aluminosilicates to the crude mixture.

Primary raw material, limestone, is the most widely used neutralizing agent for hazardous materials. 3. Ash component of waste is effectively used as raw material, thereby no secondary waste is generated from the cement plant. 4. Trace elements such as heavy metals are safely captured in the cement clinker.
kiln operations lead to higher energy consumption and energy costs. As a result, the specific maintenance cost also increases and equipment life time decreases. The specific maintenance cost amounts approximately to 20-25 per cent of total production costs in the cement industry, ranking second after energy and fuel costs. According to VDZ
Typical rotary kilns (example in Figure 4) are more than 40 m long. The inside of the kiln is lined with refractory bricks. Temperature increases along the length of the kiln from 850 – 950 o C at the inlet to 1450 – 1500 o C at the outlet. The choice of the refractory linings will thus depend on the temperature properties of the materials used and their cost.
Temperature Measurement for Cement & Lime Kilns. The axis of rotation is tilted so that gravity continuously moves a product like limestone from the high end, down the furnace toward a burner at the low end where the product is discharged into the clinker cooler. Rotary kilns are used in a variety of processes, though primarily in the production of lime, dolomite and cement.
