Vibratory Screens | McLanahan

If the screen is only operating at 75% efficiency, then 25% of the desired product is going somewhere else. The performance of a screen is affected by four variables: eccentric throw, frequency (rpm), angle of adjustment and throw direction. By manipulating these variables, the operator can dial in the screen to match the application and material.
