Product Introduction
Magnesite round grinding disc made of magnesium powder and silicon carbide for stone grinding and polishing.
Magnesite round grinding disc is a traditional stone grinding tool with a long history. It is known for its low cost and stable grinding quality, and still plays an important role in the fields of stone processing and floor renovation, especially in the rough grinding and leveling stages

Product composition and composition of Magnesite round grinding disc
The Magnesite round grinding disc is usually in the form of a circular block, which can be installed separately or in combination on the grinding machine for use.
It is mainly composed of the following materials:
- Abrasive: mainly green silicon carbide (commonly used, high hardness, sharp) or black silicon carbide.
- Adhesive: Magnesium oxide and magnesium chloride, which is the origin of the name "diamond bitter soil", play a role in bonding abrasives.
- Functional filler: Add other materials to adjust the hardness and self sharpening of the grinding disc.
In order to achieve different polishing effects, Magnesite round grinding discs will use abrasives of different particle sizes, forming a complete series from coarse grinding to fine polishing:
- Coarse grinding: commonly used abrasives with particle sizes ranging from 16 # to 240 # are used for rapid removal of surface scratches and leveling.
- Fine grinding: commonly used abrasives with particle sizes ranging from 240 # to 1000 # are used to eliminate traces from the previous process.
- Fine polishing: commonly used abrasives ranging from 1200 # to 3000 # or even finer are used to enhance the glossiness of stone surfaces

The core characteristics and advantages of Magnesite Round Grinding Disc
The biggest feature of the Magnesite Round Grinding Disc is its high quality and low price, with a price only about 10% of that of organic resin grinding tools.
Low cost, high cost-effectiveness: With abundant raw materials and simple manufacturing processes, it has become a very economical choice in large-scale stone processing.
Good self sharpening: During the grinding process, blunt abrasive particles can fall off in a timely manner, exposing new sharp abrasives and maintaining continuous cutting force.
Stable grinding quality: Compared to diamond grinding discs, it cuts softer and is less likely to "bite" the surface of the stone, providing a stable and uniform grinding effect.
Strong adaptability: capable of processing various materials, including granite, marble, artificial stone, microcrystalline stone, ceramic tiles, etc

Main limitations and precautions of Magnesite Round Grinding Disc
Despite its outstanding advantages, the Magnesite round grinding disc also has some inherent limitations:
Relatively low processing efficiency
Its grinding speed is not as fast as diamond grinding discs, which may not be suitable for projects with tight schedules.
01
Requires significant pressure
During operation, the grinding machine needs to provide a large down-force to ensure efficiency, and there are certain requirements for the weight of the machine.
02
There is a shelf life
After being stored for a long time (such as more than one year), the bonding agent properties of these grinding tools may change, affecting their sharpness and hardness. Therefore, they should be used as soon as possible after purchase.
03
Unstable polishing quality
The polishing effect of some domestic products may not be very stable, and other polishing tools may need to be used in pursuit of ultimate glossiness.
04
Overall, the Magnesite round grinding disc is a cost-effective choice for stone grinding. If the requirements for the construction period are not strict, or if cost control is needed during large-scale rough grinding and leveling stages, it would be an ideal tool. In addition, choosing products with stable quality can help reduce processing costs. Choosing cheefung stone grinding tools greatly improves production efficiency and reduces production costs.
