How to clean zirconia grinding ball
The cleaning method of zirconia Grinding Ball needs to be selected according to the use scenario and stain type. The following are comprehensive recommendations:
1. Conventional cleaning methods
Clean with water
Remove the ball directly, rinse the surface residue with running water, or place it in the ball mill tank and pre-grind with water for 5 minutes to remove stubborn stains, then dry. This method is suitable for most conventional grinding scenarios, easy to operate and does not damage the balls.
Detergent soak
For the more difficult to clean organic residue, it can be soaked in laboratory neutral detergent for one night, then rinsed with tap water until neutral, and finally rinsed with distilled water and dried. Note: This step is not required for new balls and is only recommended for old balls that are reused.
Two, stubborn stain treatment
Pickling process
If the stain is an oxide or metal residue, soak the balls in dilute hydrochloric acid (10% concentration) or dilute nitric acid (5% concentration) for 30 minutes, then rinse thoroughly and dry. However, it should be noted that pickling of new balls is prohibited, and protective equipment should be worn during operation.
pyroignition
For microbial contamination or extremely stubborn organic matter, the balls can be put into a high temperature furnace (such as 500-800 ° C) for 30 minutes, using high temperature decomposition of organic matter and sterilization. This method requires specialized equipment and is suitable for laboratory or industrial grade deep cleaning.
Third, cleaning precautions
Protective measure
Wear protective glasses and gloves when cleaning to avoid ball contact with skin or eyes.
Drying and storage
After cleaning, it is necessary to thoroughly dry (40-70℃ oven or natural drying) to prevent moisture residue leading to oxidation.
Store in an airtight container in a dry, light-free environment to avoid contact with acid/alkali chemicals.
Scheduled maintenance
Check ball wear every 3-6 months, broken ball rate more than 10% need to be replaced.
Clean in time after each use to avoid stain accumulation affecting the subsequent grinding effect.
4. Cleaning suggestions for different scenarios
Ink/paint grinding: priority water cleaning to avoid solvent residue.
Biological sample grinding: acid washing or high temperature burning after use to prevent cross-contamination.
Hard material grinding: Pregrinding time can be increased (e.g. 10 minutes) to remove metal debris.
Through the above method, the cleanliness and performance of the zirconia grinding ball can be effectively maintained, and the service life can be extended. The specific operation must be adjusted based on the actual stain type and device conditions.
