Vibratory screens are used to separate material of varying sizes. Common uses include: Sizing of particles on single or multiple deck systems. Removing fine powders in the dedusting process. Separating large pieces on scalping screens. Washing or wet screening or even de liquefying on a de watering screen.
How Vibratory Screens Work Screening can very easily be viewed as the most important operation in the processing plant. If the screen is only operating at 75% efficiency, then 25% of the desired product is going somewhere else.
The McLanahan MD Vibratory Screen is a compact, high capacity dry screening unit used in a variety of industries. It is capable of screening more tons per hour per square feet of screen surface area and handling larger capacities than conventional screens,
The high frequency vibrating screens achieves a high efficiency of separation and differs from its counterparts since it breaks down the surface tensionbetween particles. Also the high level of RPMs contributes to increasing the stratification of material so they separate at a much higher rate. Separation cannot take place without stratification. Furthermore, since the screen vibrates vertically, there is a 'popcorn effect' whereby the coarser particles are lifted higher and finer particles stay closer to the scre
High opening rate create high screening efficiency and production capacity, but lead to short life of screen panels. Screen hole shape. The screen hole shape is different, and the materials passing capacity varies greatly. When choosing the hole type of the vibrating screen, it should be suitable for the particle shape of the material.
Screening efficiency in vibrating screens is affected by numerous factors. From the screen plates down to materials, your screening efficiency will be high if you consider the aforementioned elements.
