When the material enters the drum screen device during the quarry screen operation, due to the inclination and rotation of the trommel assembly, the material on the screen surface is turned over and rolled, so that the qualified material (the product under the screen) is discharged through the bottom of the rear end of the trommel. The mouth is discharged, and the unqualified material is discharged through the discharge port at the tail of the trommel. Due to the turning and rolling of the material in the trommel, the material stuck in the screen hole can be ejected to prevent the screen hole from being clogged.

Drum screen application

The drum screen is specially developed for power plants, coking plants, building materials, metallurgy, chemical industry, minerals, and other industries. It overcomes the problem of screen clogging in the screening of wet materials by circular vibrating screens and linear screens and improves the screening system. Yield and reliability. The sieved sand and gravel materials can be automatically separated, and are ideal materials for manufacturers such as buildings, highways and cement building prefabricated parts.
