PRODUCTION PROCESS
Collection of Raw Material:
Walnut Harvesting: Nestled in the vibrant heart of the walnut industry, these walnut shells are collected as invaluable byproducts. After the delectable nuts are harvested and enjoyed, their robust shells are meticulously gathered, ready for transformation into exceptional performance solutions.
Cleaning and Sorting:
Initial Cleaning: We commence with a comprehensive cleaning regimen, meticulously purging each walnut shell of any last remnants of walnut meat, dust, and impurities. This stage ensures a pristine, premium-quality abrasive material.
Sorting: Through a process of precision, the shells undergo meticulous sorting to remove any oversized debris or foreign matter. This quality assurance can be expertly managed manually or with cutting-edge mechanical sorting technologies, guaranteeing superior quality.
Crushing:
Primary Crushing: After cleaning and sorting, walnut shells are introduced to high-performance crushers. They are fragmented into smaller pieces, setting the foundation for further refinement to achieve precision granularity.
Secondary Crushing: Achieving the ideal size may require additional crushing. Our state-of-the-art hammer mills, roller mills, or impact crushers are used to ensure each particle's precision performance.
Screening and Classification:
Size Classification: The crushed shells traverse a series of precision screens, categorizing them into diverse size grades. This precision step ensures our final product aligns seamlessly with the precise size requirements essential for sandblasting.
Air Classification (Optional): For unparalleled control over particle size distribution, optional air classifiers delicately separate shells into precise size fractions, tailored to your needs.
Dust Removal:
Cyclone Separators and Dust Collectors: To ensure peak performance, any fine dust produced during crushing and screening is meticulously extracted using advanced cyclone separators and dust collectors. This step ensures a flawless final product, free from fine dust and primed for sandblasting excellence.
Quality Control:
Testing: Exhaustive testing of the walnut shell media is carried out to ensure they meet the pinnacle of standards. These rigorous tests encompass particle size distribution, hardness assessments, and cleanliness checks to guarantee unwavering quality.
Inspection: Through detailed visual inspections and stringent quality control protocols, we ensure the consistency and superiority of our final product, delivering unmatched reliability across all applications.
This painstaking process results in walnut shell media of unmatched quality, ideally suited for sandblasting applications requiring a gentle yet highly effective abrasive. Renowned for being eco-friendly and less aggressive than conventional materials, our media is perfect for cleaning and polishing sensitive surfaces, ensuring exceptional performance with utmost care.
