With energy costs rising to record levels, no company can afford to ignore its inefficient systems. This is especially true for one ready-mix concrete company in upstate New York. Last year they spent nearly $100,000 on natural gas. While producing concrete is an inherently energy-intensive process, this company knew that by repairing and insulating their carbon steel rotary kiln, they would certainly lower the heat loss. The question was, by how much? Ultimately, the company realized enough savings in reduced energy bills to cover the expense in only one year. Now that’s a concrete return on investment!
Cement and Lime KilnsPROCESS DESCRIPTIONCement, lime and gypsum manufacturing processes have in common the mixing of inorganic minerals calcined at high temperatures typically using rotary kilns (vertical kilns are also used).CEMENTRegular Portland cements are the usual products for general concrete construction. The raw materials, limestone or chalk, together with clay or shale are mixed and fed to a large rotary kiln at temperatures up to 2600°F (1427°C). The mix can be taken through a number of preheater...

Why Shaft Kiln and Rotary Kiln Has Many Differences in Property?
The high quality shaft kiln performance compared with the high quality of rotary kiln; there are many differences between them both semi-finished products internal quality of cement and as the final product quality performance characteristics of concrete. The following is the differences of the cement performance. Firstly .The differences of the cement performance. 1, shaft kiln cement long setting time, largely longer than rotary kiln cements; 2, shaft kiln cement standard consistency water consumption is...
