We supply wedge wire trommel screen, shipping to New Zealand and other countries.

Trommel screen is a type of wedge wire rotary screens as sifting element used in Rotary Trommel Drums, for screening and sizing in mining, municipal solid waste and resource recovery. Trommel screens are often used for the removal of stones, soil, clay, and other large materials from mined ore and other material stockpiles.

Structure of Trommel Screen:
Trommel screen is cylindrical or tube-shaped screen mounted on an axle, which rotates to separate fine particles from larger pieces of debris.

Trommel screen can be made of various metals, mainly stainless steel.

Stainless steel wedge wire trommel screens offer several benefits:
Precise material separation, longer life expectancy, superior strength, and resistance to abrasion and corrosion.

Specification of Trommel Screen:
Trommel screen specifications vary depending on the type and size of the material being screened. Generally speaking, trommel screens come in different lengths and diameters, up to 10 feet in diameter and up to 70 feet in length. The trommel also includes adjustable baffles, which can be adjusted to separate different-sized particles.

How does trommel screen work:
When the drum turns, the material tumbles onto other material at the bottom of the drum. The materials break into smaller size pieces, or filter through the mesh holes in the screen, while the larger size material continues to be further sorted and processed.
