Introduction
Mobile aggregate screening plants are used to separate stone, sand, gravel, recycled materials, and ores into different size fractions directly at the job site. They can work as a standalone screening unit or be installed behind a crusher as part of a crushing and screening line. It is widely used in quarry, mining, construction, and recycling projects where material classification is required.
What is a Mobile Aggregate Screening Plant?
A mobile aggregate screening plant, also known as a mobile screening plant or portable screening plant, is a mobile system used to separate stone, sand, gravel, recycled materials, and ores into different size fractions on site. It is usually installed after a jaw crusher, cone crusher, or impact crusher as part of a crushing and screening line.
Depending on the screen configuration, the plant can handle materials up to 300 mm and produce multiple finished product sizes in a single operation. It is widely used in quarry, mining, construction, and recycling projects where flexible screening and easy relocation are required.
Working Principle
A mobile aggregate screening plant separates material into different size fractions through one or more vibrating screen decks. Material enters the screen, passes through different mesh openings, and is discharged through separate conveyors according to particle size.
Material Feeding
Material from a crusher, feeder, or stockpile is delivered onto the screen surface. A steady feed keeps material evenly distributed across the screening area.
Material Screening
As the screen vibrates, smaller particles pass through the mesh openings while larger particles remain on the screen surface. Different screen meshes produce different aggregate sizes.
Product Separation
Each material size is collected by an individual discharge conveyor. A single screening unit can normally produce two to four finished products at the same time.
Material Discharge
Finished materials are transferred to stockpiles, trucks, or downstream equipment. Oversized material can be sent back to the crusher in closed-circuit crushing and screening systems.
Advantages
A mobile aggregate screening plant is used to separate crushed material into different sizes directly on site. It can work alone or together with crushers to form a complete screening and crushing line. The main advantages are as follows.
Easy Site Movement
Tracked or wheeled chassis allows the unit to move between working areas without fixed installation. Suitable for projects with changing working locations.
Less Material Handling Distance
Screening is carried out close to the crushing point or stockpile area, material does not need to be transported to a fixed plant.
Quick Setup
No foundation work required. The unit can be brought into operation shortly after arriving at the site.
Multiple Size Output
One screen unit can produce 2–4 different material sizes in one pass depending on screen configuration.
Wide Application Range
Works with aggregates, sand, gravel, construction waste, coal, and ore in quarry, mining, and recycling projects.
Lower Operating Load
Integrated structure with feeding, screening, and conveying in one system. Fewer transfer points and simpler on-site layout.
Applications
Mobile aggregate screening plants are used for material separation and grading at quarry, mining, construction, and recycling sites. They work close to the operation area so material can move directly through the process without extra handling.

| Working Principle | On-site screening with integrated mobile chassis system | Centralized screening in a stationary production line |
| Structure Design | Tracked or wheeled modular integrated units | Steel structure with concrete foundation |
| Processing Capacity | 80–800+ tph depending on configuration | 100–1000+ tph in stable long-term operation |
| Efficiency | Flexible operation with reduced relocation downtime | High stability in continuous large-scale production |
| Energy Consumption | Moderate, varies with configuration and power system | Lower per ton under stable continuous operation |
| Footprint | Compact layout, no permanent foundation required | Large fixed installation area required |
| Installation Requirement | Fast setup with minimal civil work | Requires foundation construction and longer installation time |
| Maintenance | Modular components, easier field replacement | Planned shutdown required for major maintenance |
| Investment Cost | Lower infrastructure cost, flexible deployment | Higher civil construction cost, lower long-term unit cost |
| Suitable Conditions | Projects with changing sites or limited infrastructure | Permanent production sites with stable raw material supply |
| Typical Applications | Quarry relocation, mobile mining operations, temporary aggregate production | Large fixed aggregate plants and long-term mining operations |
Selection Note
Mobile systems are used where site conditions or production locations change. Fixed systems are preferred for stable, high-volume operations. Zhongyi Mobile Aggregate Screening Plant is mainly applied in quarry and mining projects that require mobility and flexible deployment.

FAQ
What is a mobile aggregate screening plant used for?
A mobile aggregate screening plant is used to separate crushed stone, gravel, or recycled materials into different sizes directly on-site. It is commonly applied in mining, quarrying, and construction projects where material grading is required without building a fixed screening facility.
What capacity range is available for mobile screening plants?
Typical capacity ranges from 80 to 800+ tph depending on configuration, screen size, and material type. Tracked units are usually used for 80–400 tph, while heavy-duty systems can reach higher output in large-scale aggregate production lines.
What materials can be processed?
The plant can handle limestone, granite, basalt, river stone, and construction waste. Hardness and moisture content will affect screening efficiency and required configuration. Pre-crushed material generally improves screening stability and output consistency.
What is the difference between tracked and wheeled types?
Tracked units move within mining or quarry sites and handle uneven terrain. Wheeled units are designed for road transport between job sites. The choice depends on whether relocation is inside one site or between multiple projects.
How much space is required for installation?
Mobile screening plants require minimal installation space compared to fixed systems. A compact layout is enough for operation, and no concrete foundation is needed. Site layout mainly depends on feeding, stockpiling, and conveyor arrangement.
Can it be integrated with a crushing system?
Yes, it can be combined with jaw, cone, or impact crushers to form a complete mobile crushing and screening production line. This setup is commonly used in aggregate plants requiring multi-stage crushing and screening.
What are the main operating cost factors?
Operating costs mainly include fuel or electricity consumption, screen mesh wear parts, and routine maintenance. Material hardness and feed stability also influence energy use and replacement frequency of consumables.
How to choose the right configuration?
Selection depends on material type, required output size, capacity demand, and site mobility conditions. Zhongyi provides customized configuration and system design based on project requirements, ensuring the equipment matches actual production conditions.
