What’s a Gold Mobile Portable Trommel Screen?

Trommel screens are one of the oldest screening devices, their structures are very simple but yet with high sorting accuracy and efficiency. The gold trommel can washing and screening material from 55 mm down to 6 mm, and even smaller sizes can be handled under wet screening conditions.
Trommels remain widely used in some screening operation, including aggregate screening plants and the screening of mill discharge streams. They are also used for wet-scrubbing ores, such as Bauxite, alluvial gold, diamond ores and etc. Usually combined with a gold sluice box to form a one-stop small gold wash plant.

Working Principle Of Portable Trommel Screen

Trommels are installed on a small angle to the horizontal or use a series of internal baffles to transport material along with the cylinder.

When the feeding material enters the roller trommel, due to the tilt and rotation of the trommel, the material on the screen surface is turned and rolled, so that the qualified material (under-screen product) is discharged through the outlet at the bottom of the rear end of the roller, and the unqualified material (upper-screen product) is discharged through the discharge port at the rear of the trommel.

Advantages Of Gold Portable Trommel Screen

The screening efficiency is high, the screen holes are not easily blocked, and the operation is smooth.
Simple structure and easy maintenance.
The portable trommel screen using special screens, high screening efficiency and longer service life can be achieved.
During the operation of the equipment, the noise generated by the materials and the rotating screen is completely isolated by the sealed dust cover, which eliminates the flying dust during the screening process and provides an excellent operating environment; the noise cannot be transmitted to the outside of the equipment, thereby reducing the equipment noise.

Structure

The drum body of the drum screen is generally divided into several sections, depending on the specific situation, the screen holes are arranged from small to large, and the screen hole diameter on each section is the same.
