ESSENTIAL FORMULAS FOR SPINNING MILL
Technical Spinning Information and Formulas:-1) Constant One pound is 7000 grains = 453.59 gramsOne skein is 120 yards = 109.7 metersOne yard = 36 inches = 0.9144 metersOne hank is 840 yards = 768.1 metersThe yarn count and hank roving number equals the number of hanks inone pound.To find the hank roving number from number of grains per yard:Divide 8.33 by the number of grains per yard.Hank roving number = 8.33 x yardGrains2) To find the speed of the front rollDivide the rev…

RINGFRAME DRAFT:-HI FRIENDS TODAY WE SEE IN THIS BLOG HOW TO GIVE DRAFT IN RINGFRAME IN SIMPLE METHOD.DRAFT:-Delivery/Feed = DraftHere we give formula for calculation draft. But actual draft(Running draft) is higher than calculated draft because of the slippage.Example:- If we run new count as 36s count from simplex hank 0.88 example given below. First we need to find slippage of running m/c
DELIVERY COUNT = 40FEED HANK = 0.88Calculated draft is 45.45 in case running d…
METER PER MINUTE TO HANK FORMULA
MPM FORMULA:-PRODUCTION FORMULA 8HRS = MPM*1.094*8*60/840/2.20456/HANK*EFF/100*NO. OF DELIVERYMPM HANK FORMULA :-MPM HANK FORMULA 8HRS = MPM*1.094*8*60/840/*EFF/100*NO. OF DELIVERYHANK TO KGS FORMULA :-HANK TO KGS FORMULA 8HRS = HANK*CONSTANT CONSTANT :-1/2.20456/HANK*EFF/100*NO. OF DELIVERYSHORT MPM FORMULA :-PRODUCTION FORMULA 8HRS = 0.2835*MPM/HANK*EFF/100*NO. OF DELIVERYWhat is 0.2835? :-1.094*8*60/840/2.20456 = 0.2835
WHAT IS DRFAT IN SPINNING MILL
DRAFT :- Reducing the Linear density of material by passing the successive pair of the rollers roating at higher speeds. This process include the silver passing over the rollers. The roller rotates speed faster than older one that means front speed is higher than middle roller middle roller speed is higher than back roller. Break draftMain draftTotal draftThin down the material is called as draft.

HOW TO CALCULATE RINGFRAME BREAKS STUDY
RINGFAME BREAKS STUDY CALCULATION :- In this blog we discuss about how to calculate the Ringframe breaks study formula. Ringframe breaks was calculated as Breaks per 100 Spindle in one hour.Formula :-No. of breaks in study(one doff) ÷ Total time of study ÷ Total No. of spindle×60(min)×100 splFor Example :-Breaks = 160Study taken time = 117 minsSpindle in ringframe = 1632= 160÷117÷1632×60×100= 5.03 Breaks/100spindle/Hour
