Asphalt Plant Screen Unit
- Special body sheet: The screening units have a robust structure using a special body sheet.
- Fully bolted structure: This allows for easy assembly and disassembly.
- Vibromotor-driven design: The screening units are equipped with vibromotors. This vibrating mechanism ensures that the aggregates pass through the screen.
- Non-clogging screen wires: The wires used in the screen units are designed to prevent clogging.
- Maintenance-free and dust-proof design: The screen units have a maintenance-free and dust-proof design.
- Easy maintenance: Thanks to the design, screen wire replacement and maintenance labor are minimized.
Alfamix Asphalt Plant Screening Unit Features
- With a capacity-dependent vibration motor
- We produce a standard 5-layer screen system or an optional 6-layer screen system. Since Alfamix does not produce a 4-layer screen, you don’t need to change wires to switch between binder abrasion or bituminous base production. This saves time and fuel.
- The valve located at the screen inlet allows the system to operate with either a bypass or a screen. This valve is controlled by a pneumatic actuator.
- Easy maintenance and wire replacement thanks to wide maintenance covers
- Drawn steel wire mesh
- Dust-proof body design
- Wide screening surface
- Long life
- Special tensioning system for wire mesh
- Designed for wire replacement from both sides
Asphalt plant screen units are made of high-quality steel. Steel is resistant to wear and corrosion, making it an ideal material for the screen unit. The screen unit is generally designed in a closed design. This design prevents dust from escaping from the screen.
One of the most important components used in modern asphalt production facilities is the asphalt plant screening unit. The main task of this unit is to separate the aggregates into correct sizes and make them suitable for production. In order to maintain production quality and to prepare the mixture in the correct proportions, the asphalt plant screening unit represents a critical stage that directly affects the efficiency of the plant. Therefore, using a high-capacity and precise screening unit is one of the most important factors determining asphalt quality.
What is an Asphalt Plant Screening Unit?
Systems that separate hot aggregate leaving the dryer within an asphalt plant according to particle size are called asphalt plant screening units. Vibrating screens used in this unit classify aggregates into different sizes, and each size is directed to a separate hot aggregate silo. This allows for the controlled use of each aggregate type in the mix recipe.
Thanks to this process, the asphalt plant screening unit ensures both production accuracy and the quality of the final asphalt mix.
How Does the Asphalt Plant Screen Unit Work?
The dried and heated aggregate leaves the dryer drum and is transported to the upper floor by the hot elevator and is poured onto the sieve unit. At this stage, the vibration of the screens comes into play, separating the aggregates according to their particle size.
The operating principle consists of the following steps:
Vibrating Screening: Separation of aggregates according to their size by the movement of the screen.
Multi-Deck Screen Structure: High precision with different sieve openings
Temperature Protection: High-temperature-resistant steel structure
Silo Transfer: Directing the separated aggregates to the hot silo compartments
Accordingly The asphalt plant screening unit is one of the most critical points in the production line.
