Cement industry is one of the main CO 2 emitters, producing 5–7% of the world's anthropogenic CO 2 emission [1].Production of 1 tonne of Portland cement emits about 0.83 tonnes of CO 2, mainly from limestone calcination in the pre-calciner or kiln system and fossil fuel combustion in the rotary kiln.As a result, there is a compelling need to develop …
Two different types of limestone :1) Dolomitic Limestone with high MgO content (LS4) as low-grade limestone and 2) Cement grade limestone (LS6) was used to produce the LC3 concrete mix. OPC was replaced with 30% and 45% to form different LC3 concrete mixes with 2:1 proportion of calcined clay and limestone respectively.
The apron feeder below the mass flow limestone bin has a significantly lower loading than that occurring with the apron feeder under the divergent geometry clay bin. This is principally due to the greatly reduced shear stress at the negatively sloping walls of the diverging clay bin, resulting in higher loads transmitted to the apron feeder.
Researchers have studied procedures to inhibit limestone action on clays as well as to set the correct temperature for firing. In this chapter, examples of clays with different …
