**The Processing Arrangement of 600,000 TPY Cement Grinding System**
1. In order to produce 42.5 cement suggest using Φ3.8×14m double level feeding & circle grinding cement superfine grinding machine, the power of motor is 2500kw as the numbers of equipments is less, the electricity consumption is less. Electric power of a equipment in one hour is 40kw.h, the electricity consumption of grinding system is about 35kw.h. Cement saves 8kw.h per ton, that is to say 600 thousand tons cement will save 3 million Yuan electricity cost. The output of each ton could reach 80tons. System equipment investment will be about 10 million Yuan. Electric power for one year is 55kw per ton. Cement grinding system equipment investment is 120,000 Yuan per equipment in one hour, reducing 6 million Yuan investment.
2. To produce 32.5 cement suggest taking use of Φ3.6×14m double level feeding circle grinding cement superfine grinding machine, motor power is 2240kw due to lower electricity consumption and less numbers of equipments. Configuration electric power of a equipment in one hour will be 35kw, and the electricity consumption of grinding system is about 30kw.h. So each ton cement will save 8kw.h, that is to say, 600,000 tons cement will save about 2.6 million Yuan electricity cost. The output of a equipment in on hour is 80tons. Equipment investment is 8 million Yuan. So the equipment investment of cement grinding system is about 100 thousand Yuan per equipment in one hour, reducing almost 6 million Yuan investment.
3. In order to produce 32.5 cement suggest using 2 segment grinding equipment solution, 1^{st} pre-grinding equipment takes use Φ3.2×3.6m circle superfine grinding machine and motor power is 475kw, 2^{nd} mill take use Φ3.5×11m double level loading circle grinding superfine machine, main motor electric power is 1800kw. Cement electric power of a equipment in one hour is 35kw. The electricity consumption of grinding system is about 30kw.h. Cement will save 8kw.h per ton, that is to say 600 thousand tons cement will save 2.6 million Yuan electricity cost. Output could reach 85ton per equipment in one hour. System equipment investment is about 8 million Yuan. Equipment investment of cement grinding system is 130 thousand Yuan per equipment in one hour, reducing investment almost 6 million. |
