SPINNING MILL PRODUCTION FROMULA

 PRODUCTION FORMULAS :-

    In spinning mill we use production formula in short method. I recommend to use  formula in elaborate. First we need some basic details is given below

GENERAL:-

1 METER = 1.094 YARD

1 LEA = 120 YARD

7 LEA = 840 YARD

1 KG = 2.20456 POUNDS

1 CM = 10 MM

1 INCH = 2.54 CM

1 INCH = 25.4 MM

    In basically we use two formula mostly. one is where we have METER PER MIN and another one is where we have REVOLUTION PER MIN

MPM FORMULA:-

PRODUCTION FORMULA 8HRS = MPM*1.094*8*60/840/2.20456/HANK*EFF/100*NO. OF DELIVERY

EXAMPLE:-

Delivery speed in MPM = 150

Hank = 0.120

Eff = 96%

    In the above formula 8 means 8Hrs(Per shift), 60 means 60 Minutes

= 150×1.09×8Hrs×60Min÷840÷2.20456÷0.120×96÷100*1

=339 Kgs/Pershift

RPM FORMULA:-

PRODUCTION FORMULA 8HRS = RPM*8*60/36/840/2.20456/COUNT/TPI*EFF/100*No. of delivery

EXAMPLE:-

Spindle speed in RPM = 1350

Hank = 1.14

Tpi = 1.59

Eff = 80%

    In the above formula 8 means 8Hrs(Per shift), 60 means 60 Minutes

=1350×8Hrs×60Min÷36÷840÷2.20456÷1.14÷1.59×80÷100*176(No. of Delivery)

=755 Kgs/Pershift

COMBER NPM PRODUCTION FORMULA 8HRS:-

FORMULA = NPM*8*60*NO. OF HEADS*FEED PER NIP* GMS /PER METER*(100-NOIL)/1000*1000*100*EFF/100

EXAMPLE:-

Delivery speed in NPM = 475

FEED /PER NIP = 4.75

NOIL = 18%

Eff = 95%

    In the above formula 8 means 8Hrs(Per shift), 60 means 60 Minutes

=475×8Hrs×60Min×8 HEADS×4.75×70(100-18)÷1000÷1000÷100×95÷100 = 472 Kgs/Per shift.

COMBER FEED PER NIP FORMULA :-

FORMULA = 3.14×BOTTOM ROLLER DIA÷RATCHET WHEEL TEETH

EXAMPLE:-

Ratchet wheel teeth = 20

Bottom roller dia = 30

FEED /PER NIP = 4.71

=3.14×30÷20 = 4.71
