A trommel screen, also known as rotary screen, is an essential unit which is used mainly in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum which is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized …
The screening area is calculated by the formula defined below: Qu is the amount (t/h) of undersize particles in the feed. Qspec is the specific screening capacity. S is the safety factor between 1–1.4 and depends …
To begin choosing the right size trommel screen for an operation, start looking at the screen size. Most operations are looking for screens between an 1/8 inch to 3 inches (.3 cm to 7.6 cm), and production rates can vary greatly depending on size selected. Smaller screens produce a finer material for reselling.

Formula: A = B * S * D * V * H * T * K * Y * P * O * W * F "A", the calculated capacity per square foot of screen area in tons per hour.
of 154.2 ton/h. The trommel efficiency was also estimated, considering that the MSW has an average particle diameter of 152 mm and that each particle impacts, at least, 20 times with the trommel surface before passing through the mesh open area. Thus, for a mesh with an open area fraction of 0.51, the trommel efficiency reaches the value of 82%.
Figure is multiplied by the sq. footage of the screen deck. • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of each deck opening. • Unique factors of that application. •
Octagon / hexagon / round trommel screen. Trommel screens different from traditional types are also manufactured to meet specific needs, e.g. octagon or hexagon trommel screen is mostly used for scrap metal recycling and waste industries; customized traditional round trommel screen is on the other hand ideal for rock scalping and washing as well …

Hello, i want to ask about trommel screen, i had a project to design a trommel screen, but i so confused about the principal to make a trommel screen design, i dont find a principal on internet, if anyone have a book/pdf about that, please share the link below. in picture below is my example design with : incline 4degree; size = ID 2250 x 1000 L
complex screen capacity calculations in much shorter time. This allows for the inclusion of more and more subtle factors, which greatly increase the accuracy of the conclusions. Increased accuracy will reduce the under or over sizing of screens. Un-dersized screens cause carryover or reduced plant output. Oversized
