Calculation of cyclic load in the grinding classification process during process inspection
Calculation of cycle load, classification efficiency and grinding technology efficiency in the grinding classification process during process inspection According to the definition of classification efficiency: The other C is the cyclic load, then Ffkm Bag,Perfluoroelastomers Bag,Ffkm Sanitary Seal,Filling Seal Hebei nuoxin rubber and Plastic Products Co. , Ltd. , https://www.nosincc.com
1. Calculated cyclic load with inspection graded grinding process :
γ 5 β 4 β 3
C = —— = ————
γ 1 β 3 - β 5
The classification efficiency is generally calculated by the mass efficiency formula, and the mass efficiency formula can be derived from the fine particle size efficiency E and the coarse particle size efficiency E. 
γ 4 β 4 β 4 (β 3 - β 5 )
E fine = ——— = ————————
β 3 β 3 (β 4 - β 5 )
E thick corresponding to E fine:
(1 - β 4 )[(1 - β 3 ) - (1 - β 5 ) ]
E rough = ——————————————————
(1 - β 3 )[(1 - β 4 ) - (1 - β 5 ) ]
∴E quality =E fine- E thick
(β 3 - β 5 )(β 4 - β 5 )
Or ∴ E quality = ————————————
β 3 (β 4 - β 5 )((1 - β 3 ))
Γn and βn in the above formulas represent the yield of each product and the content of each product which is smaller than a specified particle size, respectively. [next]
Grinding technology efficiency calculation:
100 - γ 3 100 - γ
E technology = (--------) ×100%
100 - γ 2 100 - γ 1
In the formula:
γ——% by weight of the product below the upper limit of the acceptable particle size in the mill discharge
γ 1 - the weight of the product in the mill feed less than the upper limit of the acceptable particle size
γ 2 ——% by weight of milled ore in the mill
γ 3 ——% by weight of overgrind in mill discharge
2. Calculation of the calculation cycle load of the second stage grinding process :
β 3 - β 1
C = —————
β 5 - β 4
Calculation of classification efficiency:
The other E is the classification efficiency, then
γ 3 β 3 β 3  β 3 (β 5 - β 4 )
E fine = —————— = ———— = ————————
γ 1 β 1 + γ 5 β 5 β 1 + Cβ 5 β 3 β 5 - β 1 β 4
(1 - β 3 )[(1 - β 5 ) - (1 - β 4 )]
E rough = ——————————————————————
(1 - β 3 )(1 - β 5 ) - (1 - β 1 )(1 - β 4 )
Mass efficiency: E quality = E fine - E thick
