The evaluation by customer: Because of our high requirements for final particule granularity, I have followed the views of LIMING engineer with a two-stage crushing - a PE Jaw Crusher for primary crushing and two Hydraulic Cone Crusher HST160 for secondary crushing. Quite stable performance, also the production makes me satisfied. To my most pleasant surprise, the intelligent operation of machine has saved me a lot of time and also costs.

• ### calculation of mill settings - sasta

So far we have worked on one ton of cane and as mill roll speeds are usually given in feet/minute we must now establish a crushing rate in tons per minute. Crushing Rate= 170 tons cane per hour. =170 tons cane per minute. 60. ='2.83 tons cane per minute. .. (4). We now have to calculate the peripheral speed of the mill.

• ### POWER IN ROLLING Power is applied to the rolling mill by applying

Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm 'a' Ie. Power= (4P.π.a.N/60x1000) Kw. Where P=Load in Newton, a=moment arm in meters and. N=speed rollers. This gives the power required for deformation of

• ### Hot Rolling Mill Hydraulic Gap Control (HGC) thickness control

The mill stretch compensation and other disturbances during the rolling process are compensated and a rolling speed dependent, adaptive PI controller is developed The mill stretch force can be measured by load cells or calculated from the measured HGC pressure and can be used to calculate the mill stretch. The mill.

Sep 9, 2014 Furthermore, the minimum achievable thickness during asymmetric rolling could be correlated to the cross-shear ratio, which, in turn, could be related to the rolling speed ratio. From the experimental results, a formula to calculate the minimum achievable thickness was established, considering the
