Understanding the features of the three main types of stone grinding machines can help you make better use of them, improve your efficiency, and achieve better results in your work.
First, the Bridge Grinding Machine
The bridge grinding machine is designed based on the grinding and polishing principles used in stone processing lines. It has been modified to incorporate the advantages of handheld grinders. This machine typically operates at 220V or 380V, with a power range of 3.5 to 7.5 kW. The marble grinding disc usually rotates at around 480 RPM, while the granite disc runs at approximately 1700 RPM. Some models also feature variable frequency control for smooth speed adjustment. With a weight ranging from 210 kg to 310 kg, it offers strong grinding force, a wide selection of abrasive tools, and high productivity, making it ideal for large-scale floor grinding tasks.
Second, the Multi-Head Multi-Disc Grinder
The multi-head multi-disc grinder combines the working principle of the bridge grinder with that of a single-head disc machine. It is available in 220V or 380V configurations, with a power range of 3.5 to 7.5 kW. Its standard grinding head speed is around 600 RPM, while planetary heads can reach up to 2600 RPM. The machine weighs between 140 kg and 350 kg, making it easy to handle and operate. It's known for its user-friendly design, good safety performance, and versatility in different applications.
Third, the Single-Head Disc Machine
The single-head disc machine is more compact and lightweight, operating on 220V with a power range of 1.5 to 2.5 kW. It typically runs at 150 to 300 RPM and weighs between 45 kg and 100 kg. This type of machine is best suited for small areas or detailed work where precision and control are needed.
