Tube Holder Speed Holder speed reduce from 120 to 60 rpm, the filling wastage reduced 15% Analyze XsBox plot D M A I C 1 2270280290processQty (kg)Mixing Yield vs RO water shortage(means are indicated by solid circles)Mean: Mean: kg RO water was short about 10 kg we added in mixing vessel. Reason: Actual RO water was lower than flow meter setting. The flow meter suit for 4 tons batch mixing, not suit for 300kg mixing Action: Weighing RO water before adding in mixing vessel RO Water Quantity Improvement Mixing yield increased 3% after RO water reach Spec.

Viscosity Comparison by RO water Change Two sample Test Dotplot D M A I C 21295290285YieldMixing Yield vs Bulk Remain in Vessel Lot of bulk was remained in mixing vessel after transfer chemical was remained in weighing bags. Reason: High viscosity of bulk and chemical. Action: ?Use special tools to scrap the bulk from the wall of vessel. ? Use metal bucket instead of plastic bag. Remained Bulk Chemical Reduction Mixing yield increased 2 % after using tool scrap the bulk from vessel Summary of Analysis D M A I C ? Operators skill are affected filling wastage ?When we decide use stainless steel to replace the small plastic bags, bulk wastage reduce 9%. ?Reducing the holder searching mark speed, filling yield also reducing ?RO water was short than specification in mixing as flowmeter is not suit for small batch of mixing process. Viscosity study shows bulk quality meet spec. ?Using special tools to scrap the bulk form vessel can be increase the output.
