Frequently Asked Questions
Trommel screens are rotating industrial screening machines that operators use to separate materials by size, usually referring particularly to minerals, biomass (dirt, rock, soil, aggregates) and other types of waste.
Trommel machines are a staple in applications across many industries, but particularly in recycling, waste processing, gardening, landscaping and mining.
First, the cylindrical drum is filled with the raw materials that need to be filtered. As the drum moves in a circular motion, the finer particles and pieces pass through the screen of the rotating drum like a colander and are collected in a skip bin or moved elsewhere. While the larger pieces remain in the centre of the drum, like wood chips.
Trommel screens are highly efficient when it comes to sorting/filtering solid materials by size which translates to uses across many industrial applications. Whether to process and sort out aggregates in mining, to screen for higher quality ingredients in food, or to act as a filter in part of a process in a solid waste processing industry, or manufacturing facilities.
Besides these benefits trommel machines excel over other types of industrial screening with:
- Optimal size separations
- Large barrel screen for easy loading and faster processing
- Large processing capacity
- Low power consumption
- Long service life
- Minimal maintenance
There aren’t any formal trommel screen ‘types’ but there are different specifications that you should pay more attention to in regards to your company’s industry, worksite, desired application and use.
Consider these factors when shopping for a trommel screen:
Workload/Production rate
Consider both the amount of material your trommel screen needs to turn over per hour. If you have a high workflow, opt for a double trommel drum machine for better capacity to filter a large amount of product. You also need to take into account screen size (most operators choose a screen between 0.3cm to 7.6cm) as it will influence how quickly the drum can be filled, and the materials processed.
Desired size of trommel ‘fines’
The screen size or entry point of trommel screens will also influence how fine the end particles that get filtered through the drums.
Worksite space requirements or limitation
Smaller yards or worksites, unfortunately, translate to less space to work with. For a smaller yard, consider getting a smaller trommel screen and installing a conveyor belt to help automate and optimise your screening efficiency in the limited space.
Customizability
Depending on your work requirements, you may need to take into consideration other features of your trommel. For example, if you live in a city with dust regulations your trommel screening machine might also need a dust cover.
Find out about the work environmental regulations of your location and talk to one of our staff for more assistance in tailoring the ideal package for your company’s needs and worksite.
Trommel machines have been used across a wide variety of industrial processing applications, such as to:
- improve recovery of fuel, as part of filtering process for wastewater (wet screening)
- mineral processing in order to grade raw materials
- screening soil compost to create a finer and superior product
- in food manufacturing or processing facilities to screen smaller raw food products that are strong enough to withstand the moving force of the drum for quality control
The typical angle is 5 degrees, with a drum speed of 18-20rpm.

How Does It Work?
Trommel machines are a newer and more efficient type of screening equipment, consisting of a motor, reducer, roller, unit, frame, sealing cover, inlet and outlet. The outside is sealed with a sealing cage which prevents environmental pollution. The machine itself is fitted with a screen curved into a cylinder, which rotates at a certain speed to sort raw material as it’s fed through the opening. Materials are separated from the top to the bottom through the screening cylinder, with the fine end product discharged from the lower part of the front end.
Trommel Machines For Your Business
Trommel machines are a useful tool to have at your disposal, as they can process and refine a variety of dry and wet raw materials with speed. As a waste management product, trommel screens can simultaneously recover valuable materials for future use, improve the recovery of fuel-derived solid waste and form end products for construction and gardening purposes. As Australian businesses move towards more sustainable waste management practices, Waste Initiatives’ growing suite of waste recycling products gives you the opportunity to lead the way with the most innovative equipment available.
