Effective Bolt Stabilization. The orignial Ridgeback™ was designed by our engineers to solve bolting problems that users were encountering when liners were installed. With standard bolts, there is a 1/8” all-around clearance between the bolt and the liner; therefore, when the bolt is installed, it rests on two points and is not stable. To
The Clarkester™ Tester accurately calibrates tightening tool torque to bolt tension, prior to installation, to virtually eliminate loose and broken bolts in structural and mill liner applications. The Clarkester™ is available with load capacity up to 250,000 pounds and bolt sizes up to 2 ½”. In addition, torque capacity is considerably

Unless the bolt tightening sequence is specified by the Service Manual, the fasteners should be tightened in a cross pattern. Use Step 1 through Step 5 unless the tightening sequence is specified: 1. Hand tighten all fasteners. Larger fasteners may require the use of a small hand wrench. 2. Torque all fasteners to 40% of full torque. 3. Torque
3 Common causes of bolt failure Most mill operators are familiar with (and regularly go through) a process known as re-torque. Re-torque is an expensive exercise resulting in lost production, but is believed to be necessary in order to avoid bolt failures that cause unplanned shutdowns.
Bolt Torque Charts These charts show suggested maximum torque values for threaded products and are intended only as a guide. Always refer to the manufacturers recommended torque values if possible. CDI Torque Products is not responsible for any application of torque or it's consequences as a result of using this chart. Use at your own risk!
S p = Bolt material Proof Strength (lb f / in 2) A s = Bolt Thread Tensile Stress Area (in 2) Nut "K Factor" There are several factors that affect the relationship between the applied bolt torque and the resulting bolt tension. All of those factors are summarized in single variable that is known as the nut "K Factor".
Torque specifications for fasteners. A bolt of the same size, thread, and material in a given grade can generally be tightened to a given torque; for example, grade-5, 1/4-20 should be torqued no more than 7 ft-lb in cast iron or 6 ft-lb in aluminum.
Mill liner bolts and flight bars are another areas where speed and torque are required. You can also hire Norbar & RAD nut runners. Pneumatic nutrunners are used processing plants for liner bolts on mills, crushers wear plate bolts, mill liner bolts, trunnion bolts, foundation bolts,etc.
Torque specifications are shown either as an exact figure, or a specific range . Follow any special instructions or multi-step directions carefully to assure correct final torque . There may be different specifications for different size bolts, bolts in different positions, tightening bolts in several stages, or a cold engine vs . a warm engine
