SPINNING MILL SHORT FORMULA EXPLANATION

 SPINNING MILL SHORT 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

Mostly Spinning people use short formula like

0.2835×Delivery speed in mpm÷ Hank for MPM to Kgs

And 1693×1.890(weight in kg)×count for Find autoconer cone length.

Where its comes?

First we take short formula 0.2835

Here we use 0.2835 and MPM and Hank. What was the actual formula

MPM*1.094*8*60/840/2.20456/HANK*EFF/100*No. of delivery

so we omit the MPM And hank in this formula

1.094*8*60/840/2.20456 = 0.2835.

Second we take short formula 1693

We use formula the above same

Length*1.094*8*60/840/2.20456/count = Weight

But here we need the Length. So reverse the formula

840*2.20456*1.094 =1692.71 = 1693.

ELABORATE FORMULA

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

MPM FORMULA:-

PRODUCTION FORMULA 8HRS = MPM×1.094×8×60÷840÷2.20456÷HANK*EFF÷100×No. of delivery

RPM FORMULA:-

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

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

COMBER FEED PER NIP FORMULA :-

FORMULA = 3.14×BOTTOM ROLLER DIA÷RATCHET WHEEL TEETH
