eagle cement posts p3.4 billion net income in 2020 publicly-listed cement manufacturing firm eagle cement corporation (eagle cement) posted a 44% dip in net income to p3.4 billion, down from p6.0 billion in 2019, after a strong start in 2020 was disrupted by the implementation of lockdown measures in the wake of the covid-19 pandemic that began in mid-march of the year.
cement manufacturing process flow chart. (i) drying zones: in the wet process, the drying zone is comparatively larger than the dry process. it is because the raw material in slurry form is directly fed into the kiln which has more amount of water. as shown in the figure it is the upper portion of the kiln.
