PRODUCTION PROCESS
Collection of Raw Material:
Walnut Harvesting: As a valuable byproduct of the thriving walnut industry, these walnut shells are meticulously gathered after the nuts have been harvested and the delicious edible parts have been removed. This sustainable approach transforms waste into a versatile resource, ready for further processing.
Cleaning and Sorting:
Initial Cleaning: The freshly collected walnut shells undergo a thorough cleaning process to eliminate any remaining walnut meat, dust, dirt, and impurities, preparing them for the next stages of refinement.
Sorting: To ensure purity and quality, the shells are carefully sorted to exclude any large debris or foreign materials. This can be achieved manually or through advanced mechanical sorting equipment, enhancing the efficiency of the process.
Crushing:
Primary Crushing: At this stage, the cleaned and sorted walnut shells are introduced into powerful crushers that adeptly break them down into smaller, more manageable pieces. This vital step ensures the shells are reduced to an optimal size for further processing.
Secondary Crushing: To achieve the precise size required, additional crushing may be performed using sophisticated equipment like hammer mills, roller mills, or impact crushers, ensuring the perfect granularity is reached.
Screening and Classification:
Size Classification: The finely crushed walnut shells journey through a series of screens, meticulously classifying them into diverse size grades. This meticulous process guarantees that the final product perfectly meets the stringent size requirements essential for effective sandblasting applications.
Air Classification (Optional): For those seeking even finer control over particle size distribution, air classifiers offer an optional yet precise method to separate the crushed shells into exact size fractions, enhancing the versatility of the product.
Dust Removal:
Cyclone Separators and Dust Collectors: To ensure a pristine final product, any fine dust generated during the crushing and screening stages is expertly removed using state-of-the-art cyclone separators and dust collectors. This crucial step eliminates fine dust particles that could impact the performance of the sandblasting media.
Quality Control:
Testing: Rigorous testing procedures are implemented to ensure that samples of the processed walnut shell media consistently meet the required specifications. These tests include assessments of particle size distribution, hardness, and cleanliness, guaranteeing superior quality.
Inspection: Comprehensive visual inspections and stringent quality control measures are conducted to uphold the consistency and excellence of the final product, reinforcing its reliability.
This meticulously crafted process guarantees that the walnut shell media produced is of exceptionally high quality, ideally suited for sandblasting applications where a gentle yet highly effective abrasive is required. Renowned for being environmentally friendly and less aggressive than conventional sandblasting materials, it is the perfect choice for cleaning and polishing sensitive surfaces with care and precision.
