portable trommel screen
Feeding size: <6mm
Feeding density: 0-50%
Application: Sand and gravel aggregate and ore grading and screening, washing processing, coal, gold, diamond ore, silica sand, quartz stone and other ore with low mud content.
Introduction: Trommel screens are one of the oldest screening devices, their structures are very simple but yet with high sorting accuracy and efficiency.
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. Customized fixed and mobile trommel screens.
Gold trommel screen can handle material from 55 mm down to 6 mm, and even smaller sizes can be handled under wet screening conditions. Trommel screen remain widely and often work with the screening of mill discharge streams. Tumbling mill (AG, SAG, rod, and ball mills) discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AG/SAG mills, to extract pebbles to send to crushing stage.
Working principle Of 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.
