PRODUCTION PROCESS
Collection of Raw Material:
Walnut Harvesting: Our journey begins with the careful collection of walnut shells, a sustainable byproduct of the thriving walnut industry. After the nuts are harvested and their delicious cores extracted, we responsibly gather the leftover shells for transformation.
Cleaning and Sorting:
Initial Cleaning: The harvested walnut shells undergo a thorough cleansing process to eliminate any residual walnut meat, dust, dirt, or other impurities, ensuring purity from the start.
Sorting: Precision sorting follows, where shells are meticulously examined to remove large debris or foreign materials. This may be achieved manually or with state-of-the-art mechanical sorting equipment.
Crushing:
Primary Crushing: The purified and sorted shells enter our advanced crushers, where they are expertly reduced to smaller, manageable sizes, priming them for subsequent processing.
Secondary Crushing: To achieve the ideal granularity, further refining may occur through secondary crushing using hammer mills, roller mills, or impact crushers, ensuring the perfect texture for diverse applications.
Screening and Classification:
Size Classification: The crushed shells are systematically guided through a series of screens, precisely classifying them into size grades that meet the exacting standards required for sandblasting applications.
Air Classification (Optional): For an even finer adjustment of particle size distribution, air classifiers may be employed to segregate the crushed shells into meticulously defined size fractions.
Dust Removal:
Cyclone Separators and Dust Collectors: Utilizing cutting-edge cyclone separators and dust collectors, any fine dust generated during earlier stages is effectively eliminated. This crucial step ensures our final product is pristine, free from particles that could impair sandblasting media performance.
Quality Control:
Testing: Rigorous testing of the processed walnut shell media is conducted to ascertain conformity with stringent specifications, examining attributes like particle size distribution, hardness, and cleanliness.
Inspection: A series of thorough inspections and quality control measures guarantee the unwavering consistency and superior quality of the final product.
This meticulous process results in a walnut shell media of exceptional quality, perfectly suited for sandblasting applications demanding a gentle yet effective abrasive. Esteemed for its eco-friendly nature, this media is less abrasive than conventional sandblasting materials, making it the preferred choice for cleaning and polishing delicate surfaces with care.
Particle Size Distribution: Our versatile walnut shell abrasive grains are meticulously crafted, available in a range of grades tailored for diverse applications, from coarse to fine.
