Cause & effect diagram for variation in grinding time

More cost per litre / lesser value yield

Volume of the batch is

coming less

Addition resin in place of

solvent

Addition of RM(s) are not proper

Checking of wt/10lit is not proper

Evaporation of the solvent during

processing of the batch

Substitutions

Visc is kept on higher side of the specification

Lesser solvent intake of the resin

Properties of substitutions are

not same

The weighing balance used is not suitable for the

purpose

Kg / L conversion charts are not used

Error in weighing balance

Error in flowmeter

Effect of temp.in addition of resin & solvent through flowmeter

Leftout powder quantity in bags after charging

Error in thermometer

Temp. is not properly maintained

Error in weighing balance

The weighing balace used is not suitable for the

perpose

Wt/10lit cup is not calibrated

Mixers are not properly calibrated

Error in taking air dip

Effect of temp.in taking air dip

Difference in price of the substitution

Sticking losses in HSD &

mixers
