Hydraulic accumulator nitrogen pre-charge pressure below the required value
Tensioning cylinder rod seal leaking, causing oil loss and pressure drop
Hydraulic pump delivering below the rated pressure
Tensioning system control valve sticking or leaking by
Normal abrasive wear from hard clinker or raw meal over the tire service life
Localized wear from an off-center material feed distributing the load unevenly
Tire cracking from thermal fatigue if the mill was started with cold tires against a hot table
Operating the mill below the minimum material bed depth, causing roller-to-table contact

How to diagnose hydraulic tensioning faults on a Loesche LM Series VRM
Low roller grinding force means the hydraulic tensioning system has a leak or the accumulator nitrogen charge is low. Check the accumulator pre-charge before looking at the cylinder seals.
How to diagnose roller and table vibration on a Loesche LM Series VRM
VRM vibration almost always means the material bed on the grinding table is too thin. Increase the dam ring height or reduce the separator speed to build the bed before increasing feed rate.
How to assess roller tire wear on a Loesche LM Series VRM
Worn roller tires increase specific power consumption and degrade product fineness. Measure the tire profile with a profile gauge during a planned stop and schedule replacement when wear reaches the minimum profile depth.
