The phrase "a general equation for" is correct and usable in written English.
It can be used when introducing a mathematical or scientific formula that applies broadly to a category of problems or situations.
Example: "In physics, we often refer to a general equation for motion that can be applied to various scenarios."
Alternatives: "a universal formula for" or "a broad equation for".
A general equation for generating three-dimensional (3D) EEMD components based on the comparable minimal scale combination principle is derived for further applications.
