Continuous Grinding
Abstract
Continuous Grinding Solution
The continuous stone grinding machine, as the core equipment of the production line, its performance directly affects the processing efficiency, surface quality and cost. The mainstream frame structure achieves efficient grinding through a combined motion of "cylinder lifting + conveyor belt transmission + servo swinging + main motor rotation", and is particularly proficient in processing high-gloss materials.
However, the traditional drive control method for continuous grinding machine has long relied on the combination of "contactor + motor". Although this mode can meet basic processing requirement, it gradually reveal significant shortcomings:
High energy consumption: Constant power output at full speed, significant energy waste in low-load conditions;
Large startup shock: Direct start-stop of the contactor is easily cause mechanical shock, leading to belt relaxation (requiring frequent replacement), increased gear wear, and shortened equipment lifespan;
Heavy burden on the power grid: Low power factor and large reactive power loss during industrial frequency operation, not only increasing line losses but also potentially causing insufficient transformer capacity and frequent tripping of switches;
Lack of speed regulation capability: Fixed rotational speed is difficult to meet the grinding requirements for different thickness and hardness of materials, and excessively high rotational speed may cause the material to be overgrinded, while an excessively low rotational speed will affect the smooth surface effect.
Solution
In response to the above issues, SAVCH has launched a core transformation solution of "permanent magnet motor + high performance frequency converter". This solution reconfigures the continuous mill power system from the drive end and upgrades the original split-type scheme to an integrated design, helping to achieve the three goals of "energy saving, efficiency improvement, and equipment longevity extension" in the continuous mill transformation.

Product Highlights
Split Type solution:
By adopting the "frequency converter + permanent magnet motor" configuration, the original structure can be transformed more quickly. After inputting automotive grade permanent magnets onto the rotor of the permanent magnet synchronous motor, the rotor magnetic field is established by the permanent magnets, which can increase the motor efficiency by 5 to 10%, enable to operate with low power consumption at high power levels.
