Therefore, design rules are often used in place of the governing equations in the design of a trommel screen. When designing a trommel screen, the main factors affecting the screening efficiency and production rate are the rotational velocity of the drum, mass flow rate of feed particles, size of the drum and inclination of trommel screen.
Design equations for a trommel screen. A trommel screen has two distinct types: auger and tensioned screens. Both use lift-and-throw action to separate material. Smaller materials flow through the holes of the screen, while the larger ones exit at the other end. The rate of material flow is controlled by the slope of the machine.
There are a lot of ways you can have your trommel set up and how you do that can make a big difference. To help you configure the efficiency of your trommel screen and get the most out of the material …
Design and Operation. A trommel screen consists of a large, cylindrical drum that rotates around its axis. The drum is typically mounted at a slight incline, usually between 2 and 5 degrees. The core components of a trommel screen include: The Drum: Made from metal or other durable materials, the drum has a series of perforations or …
