Crusher vibration problem AMP Maintenance Forums
Let us imagine that motor pulley got unbalance and we get high vibration in motor.If i increase the weight of crusher rotor mass by using higher weight hammers.will my motor unbalanced vibration reduce. If yes means is it happening in my case

Hammer crusher influences of design and execution of
lar case the possible unbalance of the crusher rotor for the speed of 24.7 Hz was determined at εp ω 2 = 0.105 ms-1, where ε p is the specific unbalance and ω is the circular operating excitation frequency. The determination of excitation force according to ČSN 73 0032 used a safety reserve cor-

SKF Copperhead takes the “crash” out of crushers
Crushers Fans Pumps Motors Grinding mills Hoists Anywhere vibration causes machinery problems Can you tell when your horizontal impactor rotor has excessive wear? Can you tell when rotor unbalance is causing bearing damage? Do you know if/when a blow bar is loose enough to fly off?

Common Problems and Solutions of PF Series Impact Crusher
The rotor of PF series impact crusher is rotating at high speed when it works. Since most of the rotors adopt casting molding process which results that many places are not well processed, some places of rotor are irregular and unbalance. When rotation speed up to 760r / min, the machine is easy partial, resulting in bearings friction

7 Hammer Crusher Common Problems And Solutions
The crusher machine divides into a single rotor and a double rotor. The single rotor is divided into reversible and irreversible. The hammer crusher is widely used for fine crushing of medium hardness materials because of its high productivity and easy maintenance. The hammer mill crushers play an important role in the whole stone crusher plant.

Unbalanced Voltages and Electric Motors: Causes and
Unbalanced voltages at motor terminals cause phase current unbalance ranging from 6 to 10 times the percent voltage unbalance for a fully loaded motor. As an example, if voltage unbalance is 1%, then current unbalance could be anywhere from 6% to 10%. This causes motor over current resulting in
