Ld Ratio Reiloy Westland Corporation The ld ratio is the ratio of the flighted length of the screw to its outside diameter the ratio calculation is calculated by dividing the flighted length of the screw by its nominal diameter although several injection molding machine manufacturers now offer a choice of injection units most injection screws use a 201 ld ratio Length Diameter Ratio Of A Ball Mill Isball Mill Length diameter ratio for ball mill queen of sheba the rod mill media and ceramic ball mill media appearance ratio rod mill whose appearance is the same as that of the industrial ball mill the difference is that the ratios of cylinder shape are different for example the length ratio of the rod mill to the diameter is generally 15 20 and the inside lining plate on the end cap is the Pellet Dies Feed Mill Machinery Glossary Ld ratio the ld ratio is the effective length l divided by the hole diameter d high ld ratios provide high pellet die resistance as feed moves through the hole low ld ratios provide less resistance each material has an ld ratio requirement to form the material into a pellet Ratio Range For Ball Millball Mill Ball mill an overview sciencedirect topics where d is the maximum size of feed mm is compression strength mpa e is modulus of elasticity mpa b is density of material of balls kgm 3 d is inner diameter of the mill body m generally a maximum allowed ball size is situated in the range from d 18 to d24 the degree of filling the mill with balls also influences productivity of the mill and milling How Can Impact Of L D Ratio On Cement Ball Mill D bsd in the horizontal planetary ball mill is we can get that 15 is the optimal speed ratio of mill and the specific surface area of cement get price process diagnostic studies for cement
