Detailed Process Flow: Manufacturing Hezhen Xinjiang crystal tourmaline tourmaline granule tourmaline stone is a multi-stage, precision-engineered process designed to preserve the material's unique properties while ensuring uniformity and purity. Our manufacturing facility employs state-of-the-art machinery and adheres to stringent quality control protocols at every step, from raw material sourcing to final packaging. The core of our expertise lies in transforming raw tourmaline ore into highly functional granules suitable for diverse industrial applications.
1
Raw Material Sourcing & Initial Sorting
The journey begins with the meticulous selection of raw tourmaline ore from designated high-purity mines in Xinjiang. This initial stage involves careful manual and automated sorting to remove impurities like quartz, feldspar, and other gangue minerals. Our procurement team, with decades of experience, ensures that only ore with high tourmaline concentration and desirable crystalline structure is accepted. This minimizes the presence of inert materials and ensures the final product's efficacy and longevity.
2
Crushing & Primary Grinding
Once sorted, the raw tourmaline ore undergoes primary crushing using robust jaw and cone crushers. This reduces the large rocks into smaller, manageable fragments. Following this, the material proceeds to primary grinding in ball mills, where it is milled into a finer powder. This stage is critical for preparing the material for subsequent processing, ensuring uniform particle size distribution for efficient purification and further refinement. The choice of grinding media and mill speed is precisely controlled to avoid contamination and excessive heat generation.
3
Washing & Magnetic Separation
To achieve the high purity standards of Hezhen Xinjiang crystal tourmaline tourmaline granule tourmaline stone, the ground material undergoes intensive washing to remove dust, clay, and other soluble impurities. This is followed by a sophisticated multi-stage magnetic separation process. As tourmaline is often associated with iron-bearing minerals, powerful high-gradient magnetic separators are employed to effectively remove magnetic impurities, enhancing the tourmaline concentration and ensuring the material's inertness in various applications, particularly in water treatment where iron content can be detrimental.
4
Precision Drying & Calcination
After purification, the wet tourmaline powder is conveyed to precision drying ovens where moisture content is carefully controlled and reduced to minimal levels. This prevents agglomeration and ensures consistent flowability. Subsequently, the material may undergo calcination at specific temperatures (below tourmaline's decomposition point, typically around 600-800°C). This thermal treatment further enhances its structural integrity and activates its functional properties, such as far-infrared emissivity, by removing any residual organic matter or crystalline water and optimizing its surface characteristics.
5
Granulation & Sizing
The dried and calcined tourmaline powder is then subjected to granulation. Depending on the desired final product form, this can involve pressure granulation or other agglomeration techniques to form uniform granules. Following granulation, a multi-deck vibratory screening system precisely sizes the granules. This stage is critical for producing various particle size ranges, from fine powders to coarse granules (e.g., 0.5 mm to 10 mm), tailored to specific customer requirements and application methods. Each batch is meticulously checked to ensure consistent particle size distribution, which directly impacts filtration efficiency or mixing properties.
6
Final Inspection & Packaging
Before packaging, every batch of Hezhen Xinjiang crystal tourmaline tourmaline granule tourmaline stone undergoes a comprehensive final inspection. This includes checks for chemical purity using XRF, physical parameters like density and hardness, and functional attributes such as negative ion generation and FIR emissivity using specialized testing equipment. Our quality control lab ensures that all specifications, including those from ISO 9001 and internal proprietary standards, are met. Only then is the product carefully packaged into moisture-resistant bags or container111s, ensuring its integrity during transit and storage, ready for global distribution.
