Preheater

Working Principal The preheating and extensive precalcination of the raw material shorten the burningprocess. The high degree of heat utilization reduces the fuel requirement and the capital expenditure for the rotary kiln. Moreover, it is possible to use low-priced substitute fuels and materials in the calciner and to positively influence the NOx and CO emissions an additional plus point for operating economy and environmental compatibility. The suspended particles are heated by the process heat gas, then they collide with the cyclone wall as the effect of centrifugal force,drop and fall into the next stage of preheater. At the bottom of the preheat, there is pre-calcinator, which could enhance the temperature of the materials hence greatly reducing the clinker burning time in the Kiln and ensuring a higher clinker output.Specification700t/dSingle1000t/dSingle2000t/dSingle2000t/dDouble2500t/dSingle2500t/dDouble3000t/dDouble4000t/dDouble5000t/dDoubleCapacityt/d70010002000200025002500300040005000Efficiency %≥90≥92First Stage Inlet Temperature ()≤340≤340≤330≤330≤325≤325≤325≤320≤310System Pressure ResistancePa≤4800Air Lock Valve StructureOutside supporting, roller bearingCyclone StructureWelded Steel Plate, Lining with tile
