modern discharege of vertical shaft kiln
Differential Discharge Mechanized Cement Shaft Kiln – Vertical Shaft Kiln
Discharge of Φ 5.0m differential kiln (one of the differential kiln cases): there is basically no raw meal or crushed material, which improves the strength of the clinker. When the qualification rate of raw meal is less than 60%, the 3-day strength is 31- 33mpa and the 28-day strength is 48-52mpa. The output reaches 38 tons/hour.
