What are the parameters that need to be known for the selection of vibrating screen equipment?

　　Screening material name, material features, moisture, temperature, heap specific gravity, particle size distribution, screening yield, screening efficiency, product cleanliness, etc.

　　Case 1:

　　Screening material: calcite ore powder; water content 2%; normal temperature; heap specific gravity 1.7t / h;

　　Material particle size ≤ 5mm or 5 ~ 0MM; 40% ≤ +10 mesh coarse material ≤ 50%; 10 mesh ≤ finished material ≤ 100 mesh; yield > 80%,

　　150 mesh fine powder < 7%;

　　Total feed amount: ≤10 tons / hour;

　　Process: Calcite is sieved after two crushing, and the +10 mesh product re-enters the mill;

　　Case 2:

　　Screening material: natural sand after drying; temperature 60 degrees;

　　Production: 60 tons / hour;

　　Feeding particle size: 0 ~ 10mm, particle size distribution: 5mm or more of coarse material accounts for about 10%; -0.6mm of fine powder accounts for about 30%.
