The rotor is the core element of an impact crusher including a HSI horizontal shaft impactor and a VSI vertical shaft impactor This crusher has hammers or blow bars that are swung at high velocity to break apart the feed material via impact forces
The results showed that the largest repair hours due to mechanical problem occurred in the fifth month with a repair time of hours and a production loss of 5 Tons which is equivalent
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between crushing can be of two variations gravity and dynamic An example of gravity impact would be dropping a rock onto a steel plate similar to what goes on into an Autogenous Mill

The crusher rotor is the core part of crusher driven by the motor the hammer swings at high speed and crushes and grinds materials of medium hardness such as limestone through impact and abrasion As a component that drives the operation of the hammer crusher the performance of the crusher rotor directly affects the production capacity and crushing effect of the crusher
3 If a rotor is operating within 70% 75% of its critical speed the speed at which resonance occurs its natural frequency it can be considered to be a flexible rotor If it is operating below that speed it is considered rigid A rigid rotor can be balanced at the two end planes and will stay in balance when in service A flexible

The crusher machine consists of interchangeable rotors a rotor with hammers and a rotor with knives The evaluation was carried out with the same fixed grid in stainless steel with 6 mm diameter
Proper material selection and proper shaft design go a long way in avoiding failures In almost all domestic impactors we find shaft designs handed down from pre World War II standards For instance almost all shafts are shrink fitted or pressed into the rotor body and keyed These keyways in the shafts extend right to the end of the rotor body
Crusher Rotor Balancing A crusher is a machine designed for mechanically breaking down pieces of hard material into smaller pieces The primary working component of a crusher is the rotor which is fitted with crushing elements hammers teeth etc As the rotor rotates at high speed it crushes the material fed into the crushing chamber
