Types of Screens

Screen Mesh

Wire Cloth Screens

Wire Cloth Screen
These are typically a square opening screen used in most screening applications to accurately size products in both top and bottom decks of vibrating shaker screens, as well as trommel screens.


Grizzly Screen

Grizzly Screen
This is a heavy duty screen used on the top deck of our Scalper 107T, Scalper 107D and 612T/612W Trommels for rough screening applications. For crushing applications the grizzly screen comes on the 5256T Impact Crusher, the JXT Jaw Crusher and the 4043T Impact Crusher. These are made from 1 steel and vary in size from 4″ to 6″ (10.1 cm – 15.2 cm) spacing.


Punch Plate

Punch Plate Screen
This is a steel plate screen used on the top decks of Scalpers such as the 107T for rough screening of materials. Holes typically are hexagonal, circular or square, but also can be made to any customer requirements. Typical sizes range from 3″ to 6″ (7.6 cm – 15.2 cm) opening.


Finger Screen

Finger Screening Deck
This is used when a soil like product contains a lot of roots or stringy material. Finger screens cascade on top of one another, never allowing material to clog on the screen. These are commonly used on the top or bottom decks of conventional screening machines in applications like compost, landfill material or mulch.


Harp Screen

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.


Sod Deck

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.
