Shenning POM plant optimizes the extrusion granulation process
The polyoxymethylene plant of Shenhua Ning Coal Chemical Company combined with the innovation studio to optimize the process of the additives of its core equipment extruder, and achieved the effect of
reducing costs and increasing efficiency.
In the first quarter of this year, the cost of additives has been saved by 574,000 yuan
.
Since the start of production, the extrusion granulation section of the POM plant has been running stably, but the additive consumption has remained high
.
In the second half of last year, the plant tried to optimize the extruder additives, and increased the processing capacity of the extruder by 3% by changing the ratio of polyoxymethylene powder and additive feeding, expanding production capacity
.
The use time of each batch of additives has been extended from the original 3.
5 hours to more than 5 hours, and the additive preparation has been reduced from once every 14 days to once
every 9 days.
In addition, the die and vacuum cleaning frequency of the granulation system is significantly reduced
.
