Moisture control begins at the post-processing stage, immediately after grinding. Powder minerals, due to their large surface area, have a high affinity for moisture, which can lead to caking, agglomeration, and even chemical degradation. For example, kaolin used in the paper industry requires strict moisture control to ensure proper coating properties. We faced challenges where sudden changes in ambient humidity during storage caused moisture levels to rise beyond acceptable limits. Instead of accepting this, we persisted in implementing controlled environment storage facilities, equipped with dehumidifiers and humidity monitors. This persistence in maintaining optimal storage conditions ensures that moisture levels remain within the specified range, preserving the powder’s flowability and performance.​

Monitoring moisture levels throughout the supply chain is a continuous process that demands persistence. We use advanced moisture analyzers to conduct regular checks, from the moment the powder is processed to when it is ready for shipment to the port. There have been instances where moisture levels fluctuated unexpectedly, even in controlled storage, due to equipment malfunctions or human error. But we persisted in enhancing our monitoring protocols, increasing the frequency of checks and implementing automated alert systems that notify us of any deviations. This persistence in vigilant monitoring allows us to take immediate corrective actions, such as re-drying the powder, before it is shipped, ensuring that only products with optimal moisture levels reach the port.​

Re-drying processes are often necessary to correct moisture issues, and this requires persistence in achieving the right balance. Over-drying can lead to excessive fines and reduced product quality, while under-drying leaves the powder vulnerable to caking. We encountered situations where initial re-drying attempts resulted in uneven moisture distribution within the batch. Instead of giving up, we persisted in optimizing the re-drying parameters, such as temperature, air flow, and duration, and implementing a more uniform mixing process after drying. This persistence in perfecting re-drying ensures that the powder regains its optimal moisture level without compromising other quality attributes, making it suitable for shipment to the port.​

Educating staff on the importance of moisture control is another aspect where persistence pays off. Even with advanced equipment, human error can lead to moisture-related issues, such as leaving storage doors open or mishandling moisture-sensitive powders. We faced instances where untrained staff unknowingly compromised moisture control measures. But we persisted in developing comprehensive training programs, covering the science of moisture in powder minerals, proper handling procedures, and the use of monitoring equipment. This persistence in staff education ensures that everyone involved in the process understands their role in maintaining product quality, reducing the risk of moisture-related issues before shipment to the port.​

Adapting to customer-specific moisture requirements is a challenge that requires flexibility and persistence. Different customers, based on their applications, may have varying moisture tolerances. For example, a customer using talc in cosmetics may require lower moisture levels than one using it in plastics. Meeting these diverse requirements can be complex, as it may involve adjusting processing and storage conditions for each customer. We faced situations where custom moisture levels were difficult to maintain consistently. But we persisted in developing customer-specific moisture control plans, with dedicated storage areas and processing lines where necessary. This persistence in customization ensures that we can meet the unique needs of each customer, enhancing their satisfaction and ensuring that our products are readily accepted when they reach the port.​
