Bolt torque can be checked with a tool such as a torque wrench, but without a value as a guideline, a torque wrench offers no advantage. To arrive at the correct torque value, several other values must be found first. Two principles influence the correct clamping pressure for each bolt, known as clamp load.

3 important stud bolts charts: 1- stud bolts dimensions in inches and millimeters (number, diameter, length of stud bolts for ASME flanges of different diameter and rating); 2- stud bolts weight (in kilograms and pounds for metric and imperial bolts, by diameter and length); 3- stud bolt torque chart (tightening sequence and load to ensure proper flanged joints).

That's tiny for bolts that size. But 15 Nm +90° seems (to my gut) to be a reasonable torque value for an 8x1.25 bolt. I just did a quick test using some 8x1.25 motorcycle hardware and a quality torque wrench and measured 15 Nm+90° to be 37 Nm, with zero measurable plastic deformation on that 20mm bolt.

Drive torque is primarily influenced by the axial load on the screw and the screw's lead. F a = total axial force (N) P = lead (mm) η = efficiency of ball screw. The axial load is not only the process force (drilling, punching, etc.), but also includes the force required to move the load. Since most ball screw assemblies use profiled guide ...

The purpose of Donhad's R&D work, focused on bolt load and the correlating torque applied, is aimed primarily at reducing shutdown time associated with sag and ball mills. Bolting failures and torque integrity are contributing factors to shut down requirement; both to ensure liner life and performance,

Accepted formulae relating torque and tension, based on many tests are: M = P x D M = torque lbf.ft 60 P = bolt tension lbf D = bolt dia.ins Or for metric sizes: M = P x D M = torque N.m 5000 P = bolt tension Newtons D = bolt dia. mm These formulae may be used for bolts outside the range of the tables overleaf.

Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after assembly of the mill proper in the trunnion bearings.
