Are you aware that Trommel screens are becoming increasingly popular across a range of industries? In fact, the Trommel screen market is projected to reach a value of $180 million by the end of 2023 and may reach $250 million in the next ten years. These cutting-edge devices provide effective and affordable options for sorting and screening a variety of materials.
Let’s dig in and explore more about them.
What is a Trommel Screen?
In the field of mineral processing, trommel screens are used to sort material according to particle size. These screening devices, often referred to as a trommel or a soil trommel screener, are cylindrical in shape. They feature large openings through which raw materials can be sorted.
These materials move through a sequence of progressively smaller screens that are stacked inside one another. As the cylinder rotates, circular air currents are created, causing heavier particles to rise and fall. Lighter particles, on the other hand, are transported away perpendicular to the flow, allowing for further separation.
Types of Trommel Screens
Trommel screens come in a variety of designs, each intended to meet particular requirements and purposes. Let’s examine those types:
Inclined Trommel Screen
A Trommel screen that is tilted or inclined is referred to as an inclined Trommel screen. The inclined trommel screen is positioned at an angle as opposed to a conventional horizontal trommel screen, providing for improved screening and material separation. As the material slides down the dirt screener trommel, the angle of the screen produces a cascading action that facilitates effective sorting and sizing according to particle size.
Horizontal Trommel Screen
A revolving cylindrical drum that is positioned horizontally atop a horizontal trommel screen sorts materials according to their size. Larger materials enter the drum via one end, and as it turns, smaller particles escape through the holes. Due to their adaptability, large capacity, and effective screening abilities, horizontal trommel screens are frequently employed in sectors like mining, construction, recycling, and composting.
Rotary Trommel Screen
The revolving drum used by the rotary trommel screen is set horizontally or slightly angled. This design makes efficient screening possible by rotating the material while it tumbles and lifts it. Rotary trommel screens are widely employed in processes including sorting municipal solid waste, processing wood, and aggregate processing, as they are particularly effective for separating materials of different sizes.
Vibrating Trommel Screen
The vibrating trommel soil screener uses vibrations to improve the screening procedure. It has a vibrating screen drum that speeds up material movement for improved separation. Since the vibrations help minimize clogging and increase overall screening effectiveness, this type of trommel screen is very helpful for fine and dry materials.
Purchasing a Trommel screener, whether it be a portable Trommel screener or a Trommel topsoil screener, may greatly increase the productivity and cost-effectiveness of your business. From inclined to horizontal, each type offers a unique screening experience. But wait! Before making a purchase decision, know your screening needs and material properties. Consulting with a professional contractor can help you make an informed purchase decision.
