Select the raw material to 0.5~1.5cm; the crushed petroleum coke is crushed by grinder to less than 35 μ m; process the petroleum coke is graded according to different particle size range and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC reserve; the petroleum coke is graded according to a certain particle size ratio and mixed evenly;
Grading is closely related to grade. After the crushing and classification of materials, the particle size of the material is large and small, often divided into fine, medium and coarse size<5 μ m, 5 μ m <20 μ m size <20 μ m and 20 μ m <35 μ m (to meet the normal distribution). Different PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC are used to remove iron.
After the material of different particle size is mixed, the fineness of the material is used to improve the density of the material, while the coarse grain is used as the skeleton to improve the strength of the material. It is found that according to the above three particle size grading, and make the d50 particle size range (meet the normal distribution) between 7 μ m and 20 μ m, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC can make the graded graphite material have good performance in terms of density and strength.
