    • MATERIALS CONTROLLING
    • 1.Inspection raw materials
      2.Physical & Chemical testing(Samples picked by Technology dept requirement: Quartz stone SiO2≥98.5%,AL2O3 ≤0.5%,Fe2O3≤0.5%, Sandstone:SiO2≥97%,AL2O3≤0.8%,Fe2O3≤1.0%, Lime: active CaO≥90%,Iron Phosphorus:Fe2O3+Fe3O4≥90%
      3.Inspection Raw materials at Plant ( inspector of raw material from technology dept: watching closely on silica materials ,yellow soil Sheet iron, feldspar are forbidden mixed in raw materials .)
      4.Raw materials warehouse ( raw materials should be inspected by per car per day by warehouseman. Quality inspector would do physical and chemical testing timely.

    • GRINDING
    • 1.Control granularity maximum avoiding any sieve lost (sieve size shall be checked 2 times a day)
      2.Two times a day on checking bottom of grinder
      3.Strap workers shall inspect grinded raw materials in granularity & water by hand and eyes.(granularity within 2-0.9mm, Content≤25% water content≤0.5%
      4.Dry granularity & water content analysis two time a day in plant laboratory.(granularity within 2-0.9mm, content≤25%, Water content ≤0.5%)

    • BATCHING
    • 1.Ensure to make exact batch composition
      2.The exactness of equipment shall be inspected once a week by batch equipment department & administrator

    • MIXING
    • 1.Mixing time record shall be made per every mixing mill operation
      2.Muller mixer operator monitored by mud technological manager ( mixing methord, mixing time etc.)
      3.Mud water content & mud granularity analysis will be quickly done by laboratory.
      ( water content 5-5.5%, granularity 2mm-0.9≤15%,≤0.1mm38-44%)

    • MOULD PRODUCER
