vibration measurements were combined to identify a potentially crippling bearing fault on Cement Mill 7 at the Cemex plant in Egypt, avoiding unplanned downtime that could have cost as much as US$510,000. If the faulty bearing had not been discovered in time, it might have seized up, causing an emergency shutdown of the mill. A two-day stoppage

All of our gear units are equipped with unparalleled condition monitoring sensors. Normally, these types of sensors keep an eye on critical operating parameters like bearing temperatures, casing vibrations, etc. and trigger a mill shutdown in the case of exceedances. Our condition monitoring system does much more.
Pinion bearing damage in ball mill. Using HD measurement technologies, Bulgarian copper producer Asarel Medet AD monitors the mechanical condition of critical equipment in the open-pit mine and flotation plant. This case study deals with the successful detection of outer race damage on a ball mill pinion bearing.
PINION BEARINGS. Pinion bearings are provided of either the sleeve type or anti-friction type. Twin bearing construction may use either individual sole plates or a cast common sole plate. The unit with a common sole plate is completely assembled in our shop and is ready for installation. Normal inspection and cleaning procedure should be followed.

Cement mill equipment must withstand high vibration, shock loads, slow speeds and a high concentration of particulates. All of which means that contamination, loss of lubricant and even improper mounting techniques can all lead to failures for pinions or trunnions.
Vibration measurements are taken on the cemen t mill pinion bearings and on the concrete foundation. ODS (Operational Deflection Shapes) method is used to determine the motion of
The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor , gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives. Gear mesh frequency is present at 1x to 3x and similar amplitudes on both sides.
A very prominent merit of vibration-based monitoring lies in the fact that each and every cause of vibration in a machine (imbalance, misalignment, looseness, broken rotor bars, gear wear/breakage, damaged couplings, bearing faults, etc.) has its distinctive feature, which is often identified through the excited frequencies.

Pinion gear is one of the indispensable spare parts of ball mill equipment, according to the direction of tooth shape can be divided into straight teeth and oblique teeth, there are two kinds of key type and expansion type. Different specifications of the ball mill selection of pinion teeth and modulus are not the same. Mainly according to the speed of the mill and the bearing capacity of the
FREQUENCY ANALYSIS OF VIBRATION Vibration measurements were taken on the feed end bearings of the considered ball mill pinions. The dB amplitudes of vibration for all of the velocity spectra are referenced to 8 mm/sec. Figure 3 presents the vibration spectrum of pinion 1A in ball mill 6. Gear mesh frequency and sidebands are marked.

Pinion seals for light vehicles . Transmission shaft seals . Engine seals . Split housings for trunnion bearings in cement and grinding mills, designed to keep lubricants in and contaminants out. formulated for applications in harsh conditions and vibrations
Ball Mill PINION SHAFT BEARINGS. Pinion shaft bearings are of the SKF anti-friction type mounted in a common twin bearing assembly. Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction.
Measurements on the pinion bearings motor bearing , trunion bearings, the concrete foundations etc. As mentioned the highest measurement is the motor non drive end axially 30mm/sec . This is a synchronis motor 200RPM . 200RPM 30 pole motor 50Htz We have inspected pinion bearings ,the air clutch, covers removed from motor for a visual check.
Bearing cage damage in vertical roller mill. This case study deals with the detection of a damaged bearing cage in a gearbox driving a vertical roller mill in the Hoang Mai cement plant in Vietnam. Since 2015, an Intellinova Compact online system monitors the mechanical condition of the gearbox using HD condition monitoring technology.
In the present case study, the causes of the high vibrations on a double-drive cement mill is investigated by performing a series of vibration measurements on the cement mill pinion and the main
Cement mill equipment must withstand high vibration, shock loads, slow speeds and a high concentration of particulates. All of which means that contamination, loss of lubricant and even improper mounting techniques can all lead to failures for pinions or trunnions.
Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding are generally found in cement plants for cement grinding.
The larger the mill, the greater are the stresses between the shells and heads and the trunnions and heads. In the early 1970s, maintenance problems related to the application of gear and pinion and large speed reducer drives on dry grinding cement mills of long length drove operators to seek an alternative drive design.

The production process culminates in two ball mills. Each day, the 15-meter-long machines grind up to 5000 metric tons of clinker – the result is ready-to-use Portland cement. In each mill, two pinions and gear units transfer the force from two 2250-kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface.
