This critical (whirling speed) is dependent on the shaft dimensions, the shaft material and the shaft loads. All rotating shafts, even in the absence of external load, deflect during rotation. No shaft is perfectly straight and no shaft with attached masses is perfectly statically balanced such that the centre of gravity coincides with the axis of rotation. At Morse Air Systems, we calculate ...

As cone crushers crush and recrush the RAP to break it apart, the asphalt can be literally stripped from the RAP, creating white rock, which now requires the extra step and cost of recoating. A jaw crusher in a RAP circuit is used for primary reduction, prepping it for the cone and requiring at least two crushers, and in some instances, a vertical shaft impactor (VSI) to make a spec product.
EXPERIMENT – 1 AIM: To determine whirling speed of shaft theoretically and experimentally. APPARATUS: Apparatus for the demonstration of whirling speed of shaft. THEORY: Whirling is the rotation of a plane formed by the geometric axis of the shat and the bent shaft. The rotor whirls with large amplitudes at critical speeds. There can be a forward synchronous whirl or backward synchronous ...
