PRODUCTION PROCESS
Collection of Raw Material:
Walnut Harvesting: In a delightful cycle of sustainability, walnut shells are harvested as a natural byproduct of the thriving walnut industry. Once the rich nuts are plucked and the luscious edible parts are separated, the remaining shells are expertly gathered, ready for the next stage of transformation.
Cleaning and Sorting:
Initial Cleaning: The journey of these walnut shells begins with a thorough cleansing. Each shell is meticulously cleaned to strip away any lingering walnut meat, dust, dirt, and other impurities, setting the stage for a pristine final product.
Sorting: Precision sorting follows, where shells are diligently separated to remove any large debris or foreign materials. This crucial step, performed either manually or with sophisticated mechanical equipment, ensures only the finest materials move forward in the process.
Crushing:
Primary Crushing: The cleaned and sorted walnut shells are introduced to powerful crushers, breaking them down into smaller, refined pieces. This essential step is pivotal to achieving a size that is ideal for further enhancement and processing.
Secondary Crushing: For those seeking perfection in granularity, further crushing is employed. Utilizing hammer mills, roller mills, or impact crushers, the shells are finely tuned to meet the precise size requirements needed for their ultimate application.
Screening and Classification:
Size Classification: The journey of refinement continues as the crushed walnut shells pass through a series of sophisticated screens, classifying them into various size grades. This guarantees that the final product aligns seamlessly with the specific size demands of sandblasting applications.
Air Classification (Optional): For those desiring exquisite control over particle size distribution, air classifiers may be employed to elegantly separate the crushed shells into perfectly tailored size fractions.
Dust Removal:
Cyclone Separators and Dust Collectors: Harnessing the power of advanced technology, cyclone separators and dust collectors swiftly eliminate any fine dust generated during the crushing and screening, ensuring the final product remains untainted by fine dust particles that could compromise the performance of the sandblasting media.
Quality Control:
Testing: Rigorous testing of the processed walnut shell media ensures it meets the highest standards. Each sample undergoes precise tests for particle size distribution, hardness, and cleanliness, guaranteeing that only the finest quality product reaches our valued customers.
Inspection: Careful visual inspections and other quality control measures are implemented to sustain the consistency and excellence of the final product, leaving no room for compromise.
This meticulous process guarantees that the walnut shell media we produce is of unparalleled quality. Perfectly suited for sandblasting applications, it offers a gentle yet highly effective abrasive solution. Cherished for being environmentally friendly and less aggressive than traditional sandblasting materials, it is the ideal choice for cleaning and polishing sensitive surfaces with care and finesse.
