Stationary Trommel Screen
A stationary trommel screen is a machine used to separate materials by size. It works like this: A cylindrical drum rotates on an axis. The side of the drum is punctured, allowing material to pass through based on its particle size.
Use and Applications
Stationary trommel screens are found in an increasing range of industries, including:
- Mining: Separating ore and precious metals from soil/rock.
- Recycling: Separating recyclables like glass, metals, and plastics.
- Construction: classifying materials such as sand, gravel, and crushed stone.
- Agriculture: Separating organic waste for composting.
Components of a Stationary Trommel Screen
• Size and Diameter: The size of the drum varies according to usage, with larger drums handling higher volumes.
• Material Construction: Generally composed of ultra-hard materials such as steel or stainless steel, to be able to stand these kinds of rough conditions.
• drives the forward rotation of the drum to accomplish efficient screening.
• Infeed Chute: The material is pushed into the drum.
• Discharge Chute: The screened material comes out of the machine.
• This holds the trommel screen steady, so that it works smoothly.
• Mesh Size: varies with the desired size of material separation.
• Material Type: This can be wire mesh, rubber, or polyurethane.
Working Principle
• Material is loaded into the infeed chute, entering the rotating drum.
• Material tumbles and rolls inside the drum as it rotates. The perforated sides allow bits of material smaller than a certain size to fall through them, leaving behind particles that are too big for this stage in the process at least (and often much more than just a bit). Larger particles continue moving with or against the direction of drum rotation until they find themselves in front largely formed tubes.
• The drum’s rotational speed and angle can be adjusted for different materials to give the best separation efficiency.
Types of Stationary Trommel Screens
• Designed for industrial applications with high wear and tear, such as mining.
• Their usage areas range from small-scale composting to simple construction waste classification
• It matches the work requirements of quite sharply with drum size and mesh configuration available in many different materials too.
Benefits
• processing a lot of material in a relatively short time.
• Made of hardy materials to cope with the tough characteristics of working environments.
• Fewer moving parts in general and a simple and straightforward construction, generally speaking.
• It’s practical across all kinds of industries and on all sorts of materials.
Applications and Case Studies
• One example is a mining company that uses high-duty trommel screens to separate gold from soil.
• A quarter-turn screen that converts glass, metal, and plastic waste into big profit: one applied example at the time it was seen new.
• One instance is a farm using trommel screens to produce high-quality compost by separating organic waste from other refuse.
• It’s practical across all kinds of industries and on all sorts of materials.
Design Considerations
• To select a suitable trommel, it is very necessary to determine the volume of material to be processed.
• material such as abrasiveness, moisture content, and item size distribution.
• Assessing conditions like temperature, humidity, and exposure to corrosive substances.
• Make sure the drum’s design and mesh size meet the required separation effects.
Maintenance & Troubleshooting
• Drum and screen panels are lined up fortnightly. Keep them clean.
• Lubricate the components that come into contact with one another to protect against friction and wear.
• No Fit Analysis: wearing parts shall be replaced in time (panels and pieces).
• Motor problems: Make sure the motor and drive system are running smoothly by checking them on a regular basis.

Frequently Asked Questions
Things you would like to know
They have applications in a variety of materials, including soil, mulch, waste and other mixed recyclables. E.g., it is also used in mining for the separation of ores and minerals from waste rock.
Stationery trommel machines: This type of trommel screen is common but will be popular with some customers. It includes a rotating cylindrical drum that directs material through the screens during its rotation. The material is picked up as the drum rotates and then dropped on top of a perforated screen in order for smaller particles to pass through the openings between perforations while larger ones hole lengthwise inside the drum until they unravel at its end. It allows adjustment of rotation speed, drum angle, and screen mesh size to optimise the screening process.
The type and volume of material to be screened, the desired particle size separation specification, the ambient operating conditions with regard to temperature or dust control needs, as well as a given screening efficiency, should take precedence in considering which stationary trommel configuration one settles for. Furthermore, discuss the overall build quality and then the aftermarket service that will be given on the said trommel screen with special bespoke options for your specific use case.
A stationary trommel screen requires regular maintenance, such as inspection and cleaning of the drum, checking of screen panels, lubrication, etc. When worn-out parts are replaced and the drum is cleared, issues are addressed promptly to keep systems running smoothly reducing wear, performance degradation and equipment life span.
Stationary trommel screens have several advantages, including large material processing rates, robust, long-lasting construction, minimal moving parts for low maintenance, and user-customisable configurations to meet the varying needs of different industries with their unique input requirements. That is why trommel screens have a very low purchase and maintenance cost; they are also perfect for the screening of compost.Find out which of the following features makes the Trommels Screen a low-cost, reliable solution.
