لگزري بال مل جي چڪاس
1. PAINPOINT driven اوپننگ
Unscheduled downtime, وڌندڙ توانائي جي قيمت, and inconsistent product fineness are constant pressures in mineral processing. A compromised ball mill is often at the heart of these issues. ڇا توهان کي منهن ڏيڻو آهي:
Excessive Operational Cost: Ball mills can consume over 15% of a plant’s total energy budget. Inefficient grinding and liner wear directly inflate your costperton metric.
Unplanned Production Stops: Catastrophic failures—from trunnion bearing seizures to cracked gear teeth—result in days of lost throughput and expensive emergency repairs.
پيداوار جي معيار جي ويرينس: ڪپڙا لينر, unbalanced charge, or misaligned girth gears lead to inconsistent particle size distribution (پي ايس ڊي), jeopardizing downstream recovery rates and final product specs.
حفاظت & قابل اعتماد خطرات: Manual internal inspections are hazardous and timeconsuming, while undetected internal wear can lead to shell failures.
