The mass balance in the process is stated in equation (1). Based on the equation, the inlet mass entering is the same as the outlet massa. Mass balance data in the rotary kiln unit were obtained from operating data at the Tuban Cement Plant. ∑ I. 𝑖 =∑ I (1) Mass balance calculations are based on the law of conservation of mass passing ...

The full mercury mass flows in these three cement plants were 181 g/d, 156 g/d and 422 g/d for Plants 1, 2, and 3, respectively. The larger mercury mass flow in Plant 3 was attributed not only to the higher concentration of mercury in limestone but also to the larger clinker production in the test period.

In the present paper, a mass and thermal balance experiment of a 5000 t/d cement plant in China was performed to obtain the operating parameters and energy distribution. The …

Ambient air (2.40 kg/kg cement) and clinker (0.84 kg/kg cement) are the main input sources, accounting for 70.33% and 24.66% of the total input (Table 5), respectively. The moisture …
