Wire Cloth Screens
This is a straight wire slotted screen that is tensioned from both ends. This screen has no cross members to hang up material. Its openings are long narrow slots. The wires allow for some vibration, which increases production. These are best used in dry screening applications. They are typically 3/4″ (1.9cm) opening or smaller and are used in the bottom decks of shaker screens only.
The sod type screen is used as a top deck on conventional screening plants in dirt applications. Sod decks increase productivity in materials containing clumps of rooted material.
