The invention discloses production equipment for ceramic polished tiles with dense and fine multi-line textures and a method thereof. The equipment comprises a surface material feeding device, a line material feeding device, a longitudinal discharging device and a horizontal conveyor belt. A mixing belt of the surface material feeding device is arranged below a surface material hopper and a texture carving roller; the longitudinal discharging device is correspondingly arranged below the end part of the mixing belt; the line material feeding device comprises a front line material hopper and a rear line material hopper; a gathering narrow-mouthed hopper is arranged blow the front line material hopper; a small roller belt used for conveying line materials is arranged below the rear line material hopper; the end part of the small roller belt is connected with the gathering narrow-mouthed hoper; the longitudinal discharging device corresponds to the lower side of the gathering narrow-mouthed hopper; the longitudinal discharging device comprises a longitudinal receiving belt and a glass plate; the receiving belt is connected with a powder guiding bar which facilitates forming a longitudinal discharging cavity by using the powder guiding bar and the glass plate in the running process of the receiving belt; and the bottom of the longitudinal discharging device is connected with the horizontal conveyor belt. By the equipment with the structure and the method, the discharging time can be shortened, and the yield meets production requirement.
