grey quartz lumps for milling & filler production
Plastics and glass manufacturers source grey quartz lumps as feedstock for milling and blending operations. Lumps provide a coarse starting material for controlled grinding to target particle-size distributions used in glass and filler formulations. Request current MOQ and lead time to align material deliveries with grinding schedules and batch processing.
Material & Size Specifications
- Typical lump size distribution: 8–40 mm suitable for primary crushing and mill feed.
- Bulk density typically ~2.6–2.7 g/cm³ depending on mineral composition.
- Silica content typically high; perform silica assay to confirm specification for glass grades.
- Impurities such as iron oxide typically <1% for higher-grade industrial supplies.
Bulk Supply & Logistics Terms
- MOQ: Minimum order quantity depends on fraction and container load; request current MOQ for processing volumes.
- Lead Time: Lead time varies with sizing and container preparation; request current lead time for your batch requirements.
- Supply Capacity: Coordinated with plant-side capacity to support recurring orders and scheduled runs.
- Packaging: Jumbo bags or loose container-loads per buyer handling needs.
- Quality Check: Representative sampling and assay reports are provided for lot acceptance prior to shipment.
Industrial Applications & Processing
Glass manufacturers and compounders mill quartz lumps to produce silica powders with controlled particle-size distribution for glass melt feed or filler applications. The starting lump size and impurity profile determine grinding energy and downstream performance. Processing facilities often require representative assay data for iron and alkali content to ensure glass clarity and refractory performance. Packaging format is selected to streamline unloading into primary crushing and milling lines.
Commercial Applications & Buyer Fit
Buyers evaluate lump uniformity, silica assay, and delivery cadence when awarding supply contracts. Contract pricing on request is available for consistent monthly volumes. For exports, container-load packing and documentation are provided. Sample assays expedite qualification and reduce hold times at processing plants.
Customization & Branding Options
- Specification Flexibility: Fraction sizing and pre-crushing options can be provided to match mill feed requirements.
- Branding Support: Bag labeling and project-specific tagging are available for repeat customers.
- Packing Formats: Jumbo bags, bulk container loads, or bagged fractions for ease of handling at mills.
- Commercial Fit: Scheduled production runs and volume-tier pricing support supply planning.
