fluid couplings for mining applications | voith

Having a highly efficient and reliable drive system increases production and provides peace of mind. Whether you require fluid couplings or a customized drive package, Voith is your partner of choice. We assist you in gently accelerating your driven machine, owing to the hydrodynamic principle, thereby extending the life time of your system. At the same time, torque is limited, load sharing is facilitated and torsional vibrations are dampened. The coupling protects the drive system from damage even under extreme operating conditions, reducing downtime and ensuring a continuous production process. Furthermore, our drive solutions are reliable and specifically tailored to each drive system from individual couplings to complete drive line solutions. The transmittable power ranges from 300 W up to 6 MW. Voiths product portfolio includes constant-fill fluid couplings, fill-controlled fluid couplings, fluid couplings for diesel engines and customer-specific drive solutions.

The hydrodynamic coupling circuit is specifically designed for your chain conveyor. The coupling limits the torque in the drive chain to a defined maximum value. This protects the chains and all components against damage. The availability of the armored face conveyor increases and the maintenance costs remain low.

The coupling works with water as a non-combustible and environmentally friendly operating medium. Moreover, water is always available underground. No additional and cost-intensive explosion protection measures are necessary when installing this coupling.

vibration monitoring for planetary gearbox in vertical axis coal mill

Vibration monitoring is one of the most important methods to detect and diagnose faults in gearboxes. Planetary gearbox in vertical axis coal mill experienced high impact load and severe working condition that increase wear and shorten usage life. Existing vibration monitoring system based on overall vibration levels repeatedly causes false trips and inaccurate for in-depth analysis. To avoid costly downtime more accurate vibration monitoring is required.

This presentation will describe our strategy to improve vibration monitoring for planetary gearbox in vertical axis coal mill using spectrum analysis. Vibration analysis for planetary gearbox is more complicated than fixed shaft gearbox because planet gears mesh simultaneously with both the sun gear and the ring gear. Planetary gearbox consist of sun gear, planet gears and ring gear. A sun gear rotates around a xed center, planet gears rotate and revolve around the center of the sun gear, and ring gear is typically stationary. Characteristic frequency associated with gear failure in planetary gearbox is calculated based on gear parameters and input speed. Characteristic frequency developed for all potential gear damage: single defect on sun-planet-ring gear tooth surface and distributed pitting on every sun-planet-ring gear tooth. Takeaways 1. Overview of vibration monitoring in planetary gearbox 2. Application of spectrum analysis for planetary gearbox to detect gear fault 3. How to calculate characteristic frequency associated with planetary gear failure

experimental investigation of vibration signal of an industrial tubular ball mill: monitoring and diagnosing - sciencedirect

To achieve improvements in the production capacity and energy efficiency of an industrial tubular ball mill, a novel method, monitoring an unmeasured parameter (level of coal powder) and diagnosis of the operating modes of the mill, was proposed. Two accelerometers were installed on bearing housing to pick up the vibration transferred from the mill shaft. A system was designed to record the vibration signals and transfer them into energy amplitudes, by using a wavelet packet approach, based on the KINGVIEW program, as well as Visual C++ environment. Based on these, a series of experiments was conducted in a 250MW power plant to investigate the vibration characteristics corresponding to the effects of different levels without air particle removal, milling times, and varying levels in practical working conditions.

The experimental results show that the operating modes of the mill, such as mill over-load, stable case, etc., can be diagnosed by proper interpretation of these vibration characteristics; and also the unmeasured parameters, i.e., level of coal powder filling the mill, can be monitored on line. Finally, methods for diagnosing operating modes and a model for on line monitoring of varying level by using a non-linear partial least square (NPLS) algorithm were presented. Combining the method and the model, we believe that the performance of ball mill can be improved.

vibration monitoring system for mill granulator

Mill Granulators are used in process plants for reducing raw coal or rock ore into fine power for burning or further processing. They come in many designs but usually are rotary mills with rings. Coal crushers of all types, such as ring granulators can often cause significant and unacceptable vibrations in their supporting structures. The source of the vibration from a mill granulator is usually imbalance. This may result from normal wear and tear or from an emergency situation, for example, a broken hammer.

Most machines (with speeds ranging typically from 600 to 720 RPM) will pass through resonance during start-up and shutdown, resulting in large amplitudes in the tall structures that often support them.

Imbalance forces in rotary breakers are usually low. However, the crushing process itself and the drive system produce random vibrations over a range of frequencies. The loss of a Mill Granulator will significantly affect production causing financial losses. A continuous vibration monitoring system will give timely warning to prevent premature plant failure or unscheduled outage.

After taking care of initial installation set up the likely faults thereafter are mainly restricted to unbalance due to wear and build-up of deposits. Analysing and designing a Vibration Monitoring System must take into account the following:

A comprehensive vibration protection system would cover sensors mounted horizontal and vertical the Mill Motor and Mill bearings respectively. The inductive velocity sensors for the drive motor and low frequency piezo electric sensors on the mill (detects bearing condition, mill unbalance looseness, structural rigidity & foundations).

The model IRD7100 series of Vibration Protection Transmitters are designed to be site mounted close to the machine in an IP65 enclosure for local alarms. Measures vibration in any parameter, Peak or RMS etc. The objective of a transmitter is to reduce the cost of signal cables to the Operators Control Room.
