total 800+ productivity, Rotary Kiln would be the optimal choice
According to local production cost for lime kiln, and the lime quality requirement, the total productivity than 800+, Rotary kiln with preheater would be the optimal Choice.
After the renew design, and several successful operation for our projects more than 800tpd Rotary kiln, we got the data as bellowing
We guarantee all datas are actural happening.
a, heat consumption
PFR 880~930Kcal LOI 2% 2*450tpd
RKP 970~1030Kcal LOI 2% 1*900tpd rotary kiln with preheater
PFR cannot burn LOI 1% 2*450tpd
RKP 960~1030Kcal LOI 1% 1*900tpd rotary kiln with preheater
PFR cannot burn LOI 0.3% 2*450tpd
RKP around 1150Kcal LOI 0.3% 1*900tpd rotary kiln with preheater
PFR 830~880Kcal LOI 3.5% 2*450tpd
RKP 920~980Kcal LOI 3.5% 1*900tpd rotary kiln with preheater
b, electrical consumption LOI 2%
PFR 40~45kw.h
RKP 28~32kw.h
c, total production cost (for one middle east project)
PFR 174.8~184.3 CNY/ton
RKP 172.95~190.8 CBT/ton
d, EPC investment, RKP is 80% of PFR.
