Quarry sand gold washing rotary drum trommel screen machine for
Rotary Trommel screen has wide range of sizes and capacities,Trommel screen is a mechanical screening machine used to separate materials.Trommel screen consists of a perforated cylindrical drum that is normally elevated
at an angle at the feed end,motor,reduction unit,screen frame and
sealing cover.When materials flow towards along the inclined
rotating drum,materials jump and roll,he undersized material
smaller than the screen apertures passes through the screen, while
the oversized material exits at the other end of the drum.
Rotary trommel screen specifications
Drum screen Working principle:
The raw materials through the entrance of the Inlet will be pushed
into the rotary drum/ cylinder sieve .raw materials in the rotary
drum cylinder will be selected by the rotation of rotary drum sieve
,with the rotating of the cylinder the materials that less than the
screen mesh will flow down by gravity ,the oversize materials will
flow througn the cylinder and discharge from outlet at the machine
Rotary Drum screen Application
Quarry: suitable for screening and classifying gravel, clay, mountain
meal, sand, etc.
Coal Industry: suitable for screening and classifying lump coal, coal dust, coal
Abrasive material and ceramic industry: building sand, mica, alumina, silica sand, abrasive, refractory
Metallurgy and mining industry: quartz sand, sand, ore, titanium oxide, zinc oxide, etc.
Mechanical industry: casting sand, charcoal, grafito, powder metallurgy,
electromagnetic material and metal powder, etc
Cylinder drum screen advantages
1. Wide material adaptability: It is used for screening of various
materials. No matter it is inferior coal, slime, soot or other
materials, it can be screened smoothly.
2. High screening efficiency: The equipment can be equipped with
comb cleaning mechanism. In the screening process, the materials
entering the screening cylinder can be screened according to
impurities and dirt to improve the screening efficiency of the
3. The screening composition is large and easy to enlarge: In the
same size, the circular area is larger than other shapes, so the
effective screening area is large, so that the material can fully
contact the screening, so that the screening component per unit
time is large.
4. Good working environment: The whole screening cylinder can be
sealed with a sealed isolation cover to completely eliminate dust
and block splashing during screening and avoid pollution to the
