The GRMR raw material vertical mill of CHAENG is a kind of new high efficiency, energy saving and environment friendly grinding equipment specially for cement raw material grinding system in cement plant. Its output can reach 720 t/h, power consumption is 17~20 kWh/t. It has the advantages of high grinding efficiency, low power consumption, low noise, and little dust pollution, can meet the requirements of 300-10,000 TPD cement production line.
Mill exit temperature too low
Potential causes:
False air
Damper positions
Proposed solutions:
Reduce damper between conditioning tower and filter
Reduce damper of re-circulation air flow
Expected results:
Less humidity in mill product
Lower temperature in filter
Estimated costs:
Minimal
Implementation time:
Short-term
Roller pressure too low
Potential causes:
High vibrations
Pressure adjustment does not follow wear
Proposed solutions:
Train mill operators
Adjust pressure periodically
Expected results:
Increased feed rate and higher production
Reduced specific power consumption
Estimated costs:
Minimal
Implementation time:
Short-term
Air speed variations in mill
Potential causes:
Cone design
Inclination of nozzles
Proposed solutions:
Redesign cone
Adjust inclination of nozzles (35 ° to 60 °)
Expected results:
More uniform speed increase
Less material falling through nozzle ring
Reduced specific power consumption
Estimated costs:
Minimal
Implementation time: Mid-term
