What screening equipment is suitable for powder with a particle size of around 1200 mesh?
Thread Content
As the title suggests, our factory produces ultra-fine powders, with the requirement that the particle size be above 1200 mesh. We’re not sure what kind of screening equipment would be suitable for sorting these particles after grinding Ordinary vibration screens seem to be capable of screening up to about 500 or 600 mesh at most, right?
Table of sieve mesh numbers and pore sizes: Mesh Number, Pore Size/mm – 4, 5; 8, 2.5; 10, 2.0; 18, 1.0; 30, 0.60; 50, 0.335; 60, 0.301; 80, 0.2; 100, 0.154; 150, 0.100; 200, 0.074; 250, 0.061; 300, 0.050; 400, 0.0385; 500, 0.0308; 600, 0.0250; 700, 0.0200; 800, 0.0150. The mesh number corresponds to the number of pores per inch; the relationship between mesh number and pore size is as follows: Pore diameter (mm) = 16 / (number of pores per inch). 1 inch = 2.540 cm. Do you produce nanoscale products?
The table upstairs is incomplete, haha: 900 mesh at 15 microns, 1100 mesh at 13 microns, 1300 mesh at 11 microns; 2# – cross-flow vs. straight-flow
Only water washing and grading can be used. Dried materials cannot be distinguished.
Air flow sieves – our unit uses them
Generally, ultra-fine powders require an air classifier
