Medium crushing usually involves crushing materials with a size of about 50mm through jaw crushers, hammer crushers and other crushing equipment to further crush materials with a particle size of 0.5-20mm required for ingredients.
Grinding is a process in which carbonaceous raw materials are pulverized to small powder particles with a particle size of 0.15mm or 0.075mm by means of Raymond mill and other equipment.
Sieving is the process of dividing materials with a wide range of sizes into several granular grades with a narrower size range through a series of sieves with uniform openings. The current electrode production usually requires 4-5 granular grades and 1-2 powder granular grades.
