WhatsApp: +86 18838072829Physical upgrading of graphite is typically achieved with many stages of grinding and reduce operating costs. In this process, a highpressure grinding roller (HPGR) and a stirred mill were employed as primary comminution techniques and a nanobubble flotation column as a key separation process.
WhatsApp: +86 18838072829The use of a C2 grade of carbide is recommended for wear resistance. If it's hard in any way, it can prove to be difficult, if not impossible, without grinding. Once the skin is gone, if the iron is soft, you can machine by pretty much any means you desire. Cast iron isn't hard to machine, and has its own built in lubrication (free graphite).

WhatsApp: +86 18838072829Natural graphite is a soft material that conventional milling methods fail to grind into nanoparticles. We found that adding NaCl into graphite during milling allows obtaining graphene nanoflakes of about 50 × 200 nm 2 as evidenced by Transmission Electron Microscope (TEM). NaCl particles are substantially brittle and harder than graphite, serving as milling agents by both helping to chop ...
WhatsApp: +86 18838072829Only diamond (preferable) or carbide tools may be used for cutting graphite. Graphite and carbon are generally machined dry without using Cutting fluids (coolants). If coolants are used in some machining operations (grinding, honing, polishing) the workpiece should be dried at 300400°F (150200°C) to remove liquids absorbed by the material.
