Ground or Treated Mineral and Earth Manufacturing

NAICS 327992 · Nonmetallic Mineral Product Manufacturing · SBA size standard: 600 employees

Ground or Treated Mineral and Earth Manufacturing businesses receive bulk raw minerals such as clay, talc, feldspar, barite or diatomaceous earth, then crush, grind, mill, classify, treat, dry, blend and package them into powders, granules or treated products for sale to industrial customers. For a plant that processes custom-spec batches of ground talc and treated kaolin for ceramics, paints and filtration, the specialists convert customer specifications into mill schedules, track raw bulk inventory and finished product lots, generate batch records and certificates of analysis, schedule maintenance on mills and dryers, manage packaging lines and coordinate bulk truck or pallet shipments while the plant operator confirms quality and regulatory test results.

Workflows

Order specification and confirmation

Starts when: A customer sends a purchase order, specification sheet or request for quotation

  1. Extract required particle size, chemical composition, treatment type, packaging and quantity from the request
  2. Check the specification against current production capabilities and standard grades
  3. Draft a confirmation with target process parameters and estimated lead time
  4. Create a production order task linked to the customer requirement
  5. Flag any special testing or certification needs

Watch for: Particle size distribution and brightness values must match customer tolerances exactly; Any deviation from standard grades requires plant operator approval before confirmation

Production scheduling and mill setup

Starts when: Approved production orders and weekly capacity review

  1. Group orders by mineral type, target grind size and treatment process
  2. Sequence jobs to minimize changeover and cross-contamination between different minerals
  3. Assign equipment such as specific mills, classifiers, dryers or treatment vessels
  4. Calculate required raw material quantities and expected yield
  5. Generate daily shift targets and parameter setpoints

Watch for: Equipment must be thoroughly cleaned between incompatible minerals; Mill and classifier settings directly affect final particle size distribution

Raw material receiving and inventory

Starts when: Incoming bulk shipments by truck or rail

  1. Record supplier, lot number, weight and visual inspection results
  2. Sample for moisture and basic contaminant screening
  3. Update bulk raw inventory by mineral type and lot
  4. Generate receiving report and assign storage silo or stockpile location
  5. Flag any off-spec material for further testing or rejection

Watch for: Moisture content must be verified before unloading to prevent processing issues; Different mineral types cannot be cross-contaminated in storage

Process monitoring and batch recording

Starts when: Start of each milling or treatment run

  1. Load process parameters into equipment controls
  2. Capture real-time data on feed rate, mill speed, classifier settings, temperature and energy use
  3. Record in-process samples and lab results for particle size and other properties
  4. Generate batch production record with all measured parameters
  5. Calculate yield and material balance for the run

Watch for: Continuous logging of critical process parameters is required for traceability; Any process deviation must be noted and reviewed by the operator

Quality testing and certificate generation

Starts when: Completion of each production batch

  1. Schedule laboratory tests for particle size distribution, chemical assay, brightness, moisture and other specified properties
  2. Compare test results against customer specifications
  3. Draft certificate of analysis with test data and lot identification
  4. Release or quarantine the batch based on results
  5. Update inventory with approved finished product quantities

Watch for: All test results must be reviewed and signed off by a qualified person; Certificates must accurately reflect the tested properties of that specific lot

Packaging and shipment preparation

Starts when: Finished product ready for packaging and customer release dates

  1. Determine packaging type, bag or container size and pallet configuration per order
  2. Schedule bagging line or bulk loading operation
  3. Generate labels with lot number, production date, specifications and safety information
  4. Prepare shipping documents including bills of lading and customs paperwork if needed
  5. Coordinate truck, rail or container pickup

Watch for: Proper dust containment during bagging and palletizing operations; Accurate lot traceability on every package and shipping document

Equipment maintenance and compliance tracking

Starts when: Scheduled maintenance intervals and regulatory review dates

  1. Track operating hours on mills, crushers, dryers and dust collectors
  2. Generate preventive maintenance tasks based on manufacturer recommendations and usage
  3. Record completed maintenance and parts used
  4. Track dust control system inspections, baghouse differential pressure and emission logs
  5. Monitor renewal dates for permits, licenses and operator certifications

Watch for: Maintenance must be completed before equipment reaches critical hour thresholds; Local, state and federal environmental and safety requirements vary by location and process
