Linear vibrating screen with double vibration motor, when two vibration motors to do synchronization, repeated spins, arising from their eccentric force in a direction parallel to the axis of the motor offset, perpendicular to the direction of the motor shaft folds for a force, so the machine trajectory is a straight line. Its axis relative to the screen surface with a dip of two motor, excitation force and material under the action of the force of gravity, materials were thrown up on the screen leap forward for linear motion, so as to achieve the purpose of filtering and classification of the materials. Can be used to automate pipeline jobs
