5、Usage Instructions and Precautions

5.1Configuration and Calibration of Liquid Gear Metering Pump:

5.2Mill Activation: Introduce the grinding aid into the mill at a dosage slightly higher than the specified amount for 1-2 hours as part of the mill activation process.

5.3Production Increase Adjustment: After the activation phase, enter the production increase phase for the mill. With the product fineness and specific surface area within normal control ranges, gradually increase the mill's production based on changes in mill sound. Concurrently, increase the grinding aid dosage accordingly.

5.4Enhancement or Increase in Admixture Content:When the mill's production capacity remains unchanged, introduce the grinding aid and adjust to reduce product fineness or increase specific surface area to achieve strength enhancement. Alternatively, with consistent quality and strength, increase the admixture content through adjustments.
