Production Calculation Formula in Spinning

Posted by Default on December 28, 2018 in

Production calculation of spinning is one of the principle tasks for production manager who is responsible in spinning floor. Maximum time textile engineers forget the common spinning production calculation formula. In this article just I want try to give production calculation formula in cotton spinning.

Production calculation formula of blow room: 

Blow room production per hour, 
                                                            60 Surface speed of calendar roller X ….....….......….. X Eff. % X Waste% X No. of scatcher 
                                                  36 X 840 X Hank 


Production calculation of carding: 

                                                                                       60 
Production of carding = Surface speed of doffer x ……….....……………x Effi% x Waste% 
                                                                          36 x 840 x Sliver hank


Production calculation of Drawing: 

                                     Front roller surface speed X 60 X Efficiency% X Waste% (lb/hr) 
Production of Drawing = ……………………………………………………...………………
                                                                  36 X 840 X Hank 


Production calculation of lap former: 

                                        πDN            lap count (grain/yard)
Lap former production = …….. x 60 x …………………..….. x η x no of machine (lb/hr)
                                         36                           7000 


Production calculation of Comber: 

Production of comber per day, 
                                                                                                   100-Noil% 
= Nip/min X Feed/nip X No. of head X Feed lap weight X Efficiency X …………. X 60 X 24 
                                                                                                        100 


Production Calculation Formula of Speed Frame or Simplex: 

                                                          Flyer speed (rpm) x 60 x 8 x No of flyer x Efficiency
Production Calculation of Simplex = ……………………….....………….....………………
                                                                         TPI x 36 x 840 x Roving hank 



Production calculation formula of Ring Frame: 

                                                              Spindle r.p.m X 60 X 8 X No of spindle 
Production calculation of Ring Frame = …....………………………………...... X Efficiency 
                                                                       T.P.I X 36 X 840 X Count
