* Take a large value when the mill product size is larger than 0.3 mm, and vice versa. m 2 —— the grinding amount used in production is calculated according to the newly generated grade (-0.074mm grain size), and the relative processing amount under different feeding and arranging particle size conditions, check Table 4; 2) The number of grinding machines to be selected in the design is calculated according to formula 6 according to the original ore amount Qa of the design process: Titanium Fittings,Titanium Pipe Fittings,Titanium Tube Fittings,Titanium Flanges And Fittings SHAANXI LASTING TITANIUM INDUSTRY CO., LTD. , https://www.lastingtitanium.com
K4——Different feeding size of grinding machine and difference coefficient of different product size: 
(4)
m 1 ——The relative amount of processing of the grinding machine to be selected in the design according to the newly generated grade (-0.074mm grain size) under different feeding and arranging conditions, check Table 4;
1) The amount of grinding machine to be used in the design (excluding the return amount of closed-circuit grinding) is calculated as follows:
(5)
Q d - the processing capacity of the grinding machine to be selected in the design, ton / Taiwan · hour;
q——The unit throughput of the newly generated grade (-0.074mm grade) of the mill to be selected in the design, ton/ m3 ·hour;
V d —— the effective volume of the grinding machine to be selected in the design, m 3 ;
β d1 —— the content of the grinding machine to be selected in the design is less than 0.074mm, %;
β d2 ——The content of 哵 in the grinding machine product to be selected in the design is less than 0.074mm.
If there is no actual production data, βd1 and βd2 can be referred to Table 5 and Table 6. (6)
In the formula Q a - the original ore amount specified in the design process, ton / hour;
Q d —— the processing capacity of the grinding machine to be selected in the design, which is obtained by the formula 5, ton/set·hour;
n d ——The number of mills to be selected for design is required.
