How to Confirm Motor Power of Impact Crusher?

To confirm the motor power of impact crusher is quite important for improving the machine performance, reducing energy consumption and total investment. Motor power of impactor crusher is related with factors like material property, production rate, linear speed of rotors and crushing ratio.

According to the unit power consumption curve, we find that the power consumption gradually increases when circular velocity of rotor increases. Since impact crusher can realize the selective crushing, the largest factor for power consumption is still the physical and mechanical properties of mineral stones if other situations do not change.

What’s the influence of production rate on motor power? Higher the production rate, larger the power consumption. It is similar to the influence of rotor speed on motor power. If linear speed of rotor is high, crushing ratio will large. Consequentially, smaller the size of finished products and larger the power consumption of motor.

By virtue of the great kinetic energy, impactor crusher can crush mineral stones. Kinetic energy of impact crusher to crush material is in direct proportion to the quality of material. Therefore, the size of raw material has great influence to motor power. If there is no load on impact crusher, a larger part of power will be consumed in running the blast of rotors.

When other parameters does not change, then, larger the specification of rotors, greater the power consumption of motor. Launching torque of impact crusher is very large, so we generally equip it with wound-rotor motor. Get more via website!
