In lean times like these, manufacturers and component makers like you need to stretch your equipment investment dollar. To keep your production facilities running, a systematic and calibrated programme of preventive maintenance for your CNC machine tools like CNC lathes and machining centres is needed. This will ensure that your equipment continue to …
In present-day practice, the ore is reduced to a size many times finer than can be obtained with crushers. Over a period of many years, various fine grinding mills have been developed and used, but the ball mill has become standard due to its simplicity and low operating cost. A ball mill efficiently operated performs a wide variety of services.
The coal mill is one of the important auxiliary engines in the coal-fired power station. Its operation status is directly related to the safe and steady operation of the units. In this paper, a model-based deep learning algorithm for fault diagnosis is proposed to effectively detect the operation state of coal mills. Based on the system mechanism model of coal mills, …

A coal pulverizer monitoring system and method measures a displacement of wheels in a vertical roll wheel pulverizer using strain gauges bonded to tension rods in an ambient environment outside the hostile environment of the milling area of the pulverizer. Signals from the strain gauges reflecting strain on the tension rods are converted to a displacement of the wheels …
Maintenance cost/ERV. Ratio of total annual cost of maintenance to plant's estimated replacement value. A measure of dollars required to maintain value of the plant. Also a general indicator of maintenance cost effectiveness. A downward trend without real maintenance improvements can indicate milking of assets.
coal-fired power plants can cause thermal and pressure stresses. Over time, these can result in premature component failure and increased, necessary maintenance. Starting a unit, increasing its output, or operating at part load can also increase emissions compared to non-cyclic operation.

Coal Centre – Coal sampling and analysis standards 4 Abstract Each year, billions of tonnes of coal are traded in regional and international market for use in power generation, steel and cement making, and many other purposes. In commercial operations, the price of coal
The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion. Advantages. Good control on coal fineness.
As shown in Tables 1-4, the fault-prone components on these units are the gears, bearings, couplings, shafts, impeller/blades and electric motor. Figures 3 and 4 respectively show the schematic and pictorial representations (with the positions of the various VCM sensors) of the coal mill main drive assembly, bag house fan and booster fan.

If you're currently relying solely on reactive maintenance, then your company is probably wasting tens to hundreds of thousands of dollars every year due to a lack of a consistent preventive maintenance plan.. The good news is that starting a preventive maintenance program isn't complicated when you have a clear idea of the steps you need to take.
Checklists can be a great tool to standardize routine tasks that have to be run regularly. In the same fashion, a preventive maintenance checklist can be used to streamline a variety of preventive maintenance tasks.. However, preventive maintenance checklists are only useful if created with a purpose and include all of the necessary information.
