The power input required to maintain this condition is theoretically: hp = (W) (C) (Sin a) (2π) (N) 33.000. where W = weight of charge. C = distance of center of gravity or charge from center of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in rpm. The value of the angle a varies with the type of discharge, percent of ...
Why induction motor is used in crushers mill motors uses for crushers- why induction motor is used in crushers,Severe Duty, Heavy Duty Motors WorldWide, Our rock crusher motor can operate with several types of rock crushers, that allows the motor to be used for vertical shaft applications, such as VSI crushers, and even food duction motor.
So, if I calculate, first, the rated full load current of the induction motor, then that is given by it is 2000 HP motor, so 2000 into 746 divided by voltage that is the root 3 into 6.6 kV so 6600 multiply by 0.85 power factor and 0.9 that is the efficiency of the motor.
A synchronous motor can be used to improve the overall power factor of an electrical system by adjusting the DC excitation. The synchronous motor used specifically for power factor improvement without any mechanical load is called a synchronous condenser. The synchronous condenser is used in parallel with the load to improve the power factor.

The crusher is driven by electric motor. Drive system transmits power from the motor to the crusher's pinions shaft and also provides a form of overload protection. Normally in any ore beneficiation project squirrel cage induction motor is used as crusher motor. Since the rating of crusher motor is high, it is operated either with 6.6 KV or ...
Scrap crusher is a kind of high-power asynchronous motor, which can treat scrap to obtain pure and high quality steel. In general, the impact current of the crusher motor is usually larger when starting, and its power factor is often very low when it is running without load, and there will be short-term overload in the running process, …
This paper describes the improvement of power factor of an induction motor by using capacitor bank. When power factor is improved, automatically energy will be saved A power factor is the goal of any electrical utility company since if the power factor is less than one, they have to supply more current to the user for a given amount of power ...

Power factor is a parameter that defines how effectively power is utilized by the load. It is the ration of true power to apparent power. ... it operates at a p.f of 0.1-0.4 and rises to 0.8-0.9 at full load. Apart from induction motors, induction heating furnaces, and arc lamps also have a very poor p.f. Disadvantages of poor power factor.
05.07.2020 · Induction motors present a lagging (inductive) power factor to the power line. The power factor in large fully loaded high-speed motors can be as favorable as 90% for large high-speed motors. At 3/4 full load, the largest high-speed motor power factor can be 92%. The power factor for small low-speed motors can be as low as 50%.
