According to the theories for stretch reducing process and steel tube plastic deformation, the energy meth od was used to mesh the rolled deformation zone of the steel tube into the upper limit elements, and an admissible velocity field was constructed to deduce a series of formulas of the inner virtual power consumption of deformed bodies.
Aug 31, 2013· I was at the only specialised store in my area and held in my hands the T5 and HTD 5M pulleys and belts. The T5 have a huge tooth clearance. I estimate the backlash to maybe 0.5mm. The HTD are much better fitted but there is still a visible clearance/ movement when pulled by hand. The pulleys are made by BEA, the HTD belt is Optibelt and the T5 belt I do not remember.
No 1 rod mill/ball mill circuit was operating very effi ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being fi .

to make the BISRA calculation more accurate is to measure the mill stretch under different pressures on an empty stand, pushing the work rolls together. This way the nonlinear mill modulus curve can be measured, and used for the calculation of mill stretch. Usually this measurement also requires some corrections, since the
