Three major stone grinding machinery features

First, Bridge Grinder

The bridge grinder is designed based on the grinding and polishing principles used in stone processing lines. It's a modified version of a handheld grinder, tailored for more efficient and powerful performance. It typically operates on either 220V or 380V power supply, with power ranging from 3.5 to 7.5 kW. The marble grinding disc usually rotates at around 480 RPM, while granite discs can reach up to 1700 RPM. Some models even feature variable frequency control for smooth speed adjustment. Weighing between 210 kg and 310 kg, this machine offers excellent stability, strong grinding force, and high productivity, making it ideal for large-scale floor grinding tasks.

Second, Multi-Head Multi-Disc Grinder

This type of grinder combines the working principle of the bridge grinder with that of a single-head disc machine. It is available in both 220V and 380V configurations, with power ratings generally between 3.5 and 7.5 kW. The standard grinding head speed is around 600 RPM, while planetary heads can reach speeds of 1500 to 2600 RPM. The weight ranges from 140 kg to 350 kg, offering a balance between portability and power. It is user-friendly, easy to operate, and provides a high level of safety, making it a popular choice for medium-sized projects.

Third, Single-Head Disc Machine

The single-head disc machine is the most compact and lightweight option, operating on 220V power with a power range of 1.5 to 2.5 kW. Its rotation speed typically falls between 150 and 300 RPM, and it weighs between 45 kg and 100 kg. This makes it perfect for small areas or detailed work where precision is required. Despite its smaller size, it still delivers effective results and is often used for maintenance or touch-up jobs.

By understanding the differences between these machines, you can choose the right one for your specific needs, ensuring optimal performance and efficiency in your stone grinding projects.
