Application of FGI FD300 Series Low Voltage Frequency Inverter in impact crusher

1.Overview

The counterattack crusher has the advantages of high compressive strength, large crushing ratio and cubic particles after crushing. Widely used in building materials, ore crushing, railway, highway, energy, transportation, cement, mining, chemical industry and other industries used for fine broken materials.

The principle of counterattack crusher is mainly based on high-speed impact and repeated crushing. The motor drives the rotor to rotate at high speed. After entering the crusher, the material collides with the board hammer on the rotor at high speed, resulting in preliminary crushing. After crushing, the material will be thrown to the counterattack plate at the other end of the crushing cavity, and broken again. Finally, the material will rebound from the counter plate back to the action area of the plate hammer, forming a repeated crushing process until the material reaches the desired particle size, and then discharged from the discharge port.

2.Implementation plans

After the transformation, the motor starting mode now allows for a smoother start-up with adjustable speed control, reducing the impact on the system. The use of the FGI FD 300 series 500KW frequency inverter has also led to improved energy efficiency and overall performance of the motors. Additionally, the synchronous operation schemes implemented in the frequency inverter have effectively balanced the load, resulting in more consistent and reliable operation of the equipment. These upgrades have significantly enhanced the functionality and efficiency of the project's motor system, ultimately contributing to improved productivity and cost savings for the overall operation.

3.Application advantage

The original liquid resistance cabinet has a large impact current, and the risk of cooking is high. After transforming the crusher with easy energy FD 300 frequency inverter, the load impact is small, reduces the mechanical loss, and has no impact on the power grid.

The starting peak current of FD 300 frequency inverter motor is small, with high power factor and low reactive power loss, which extends the life of the equipment, and the running speed can be adjusted according to the working conditions of raw materials, reducing the energy consumption significantly.

FD300 frequency inverter has the protection functions of perfect overvoltage, overcurrent, phase deficiency, short circuit to the ground and so on, and can timely protect for the blockage of the card material. Effectively extends the service life of the motor and reduces the maintenance cost.
