1. Graphite crushing method

1. Mechanical crushing method: crushing by physical mechanics. Common mechanical crushing equipment includes impact crusher, hammer crusher, cone crusher, etc. Mechanical crushing method is suitable for crushing large pieces of graphite. The particles are uneven after crushing, but the cost is low.

2. Grinding crushing method: using the "point to surface" collision principle. Common grinding crushing equipment includes ball mill, vibration mill, grinder, etc. Grinding crushing method is suitable for grinding graphite micro powder. The finished product particles are uniform, but the cost is high.

2. Graphite crushing principle

1. Mechanical crushing principle: In the process of mechanical crushing, mechanical force is used to impact or wear the graphite externally to break the graphite. The smaller the graphite particles, the more physical and chemical reactions will play a decisive role in studying its properties. The principle of mechanical crushing mainly uses the fragments to collide, wear or vibrate with each other to achieve the crushing effect.

2. Principle of grinding and crushing: During the grinding and crushing process, mechanical friction, collision and other forces rub and shear the graphite, causing the particles to deform and break, and finally grind into micron or nanometer powder. The grinding and crushing principle is mainly used for the crushing of hard and brittle minerals.

III. Precautions for graphite crushing

1. Study the size and size distribution of the required particles and crush them with appropriate equipment.

2. For materials that need to change the surface properties, it is best to use grinding and crushing.

3. Ensure the switch state of the crushing equipment to avoid harming personnel and equipment.

4. Pay attention to controlling the speed and force during crushing to avoid excessive energy, resulting in melting or chemical reactions.

In short, as an important non-metallic material, graphite needs to be crushed in industrial production and scientific research. Mechanical crushing and grinding crushing are two commonly used crushing methods with different advantages and disadvantages. At the same time, some details need to be paid attention to during the crushing process to ensure the effect and safety of the crushing.
