Against the backdrop of the recycling industry being listed as a national strategic emerging industry, the waste recycling industry is entering a phase of rapid development. In a large enterprise, GTAKE GK620 AC drives work in coordination with asynchronous motors, playing a dual-axis drive role in the operation of the crusher equipment, ensuring the efficient, continuous, and stable operation of the dual-axis asynchronous motors.
The main feature of a dual-axis crusher is that it has two parallel rotating shafts, usually equipped with multiple blades or hammers. During operation, these two shafts rotate at different speeds or in opposite directions, and through the shear and impact action between the blades, the material is crushed into smaller particles.
Specific drive solution: Two AC drives separately drive two motors, independently controlling motor 1 and motor 2, to achieve simultaneous start and stop. During specific commissioning, it is necessary to ensure that the directions of motor 1 and motor 2 are opposite.
