Get Pricelinear vibrating screen is driven by double vibrating motors. When the two vibrating motors are rotating synchronously and reversely, the excitation force generated by the eccentric block offsets each other in the direction parallel to the axis of the motor, and overlaps into a resultant force in the direction perpendicular to the axis of the motor, so the motion track of the linear vibrating
Get PriceEquations of Motion Introduction: The equations of motion are used to describe various components of a moving object. Displacement, velocity, time and acceleration are the kinematic variables that can be derived from these equations. There are three equations, which are also referred to as the laws of
