Differences Between  River Materials Crushing Plant and Mountain Materials Crushing Plant

Material Properties

River materials and mountain materials can show differences in terms of physical properties.

River materials are generally smaller in size, have smoother shapes, and a softer structure. On the other hand, mountain materials can be larger in size, have sharp edges, and be harder. This difference can have an impact on the design and equipment selection of crushing and screening plants.

Crushing And Screening Process

River materials may generally require fewer crushing stages in crushing and screening plants.

Since the material is usually smaller in size and more homogeneous, the crushing process may require less energy. Mountain materials, on the other hand, are generally larger in size and more brittle, so more crushing steps may be required.

Equipment Selection

More powerful crushers and screening systems may be preferred to crush large-sized rock fragments.

In mountain material crushing and screening plants, stronger and more durable equipment can be used. For river materials, smaller-sized equipment can be used.

The construction industry relies heavily on concrete, and a key ingredient in concrete is aggregate.

Obtaining Aggregates for Concrete Batching Plants

Concrete requires aggregates of various sizes to achieve optimal strength and workability. Crushing and screening plants play a vital role in transforming raw materials into these precise gradations. Here’s a breakdown of the process:

1. Raw Material Selection: The first step involves selecting suitable raw materials. Granite, basalt, limestone, and recycled concrete are some of the most common choices. The chosen material should be strong, clean, and free from impurities that can affect concrete quality.
2. Crushing: The raw material is fed into the crushing plant. Jaw crushers are often used for the initial breakdown of large rocks. Subsequently, cone crushers or impact crushers further reduce the size of the material.
3. Screening: After crushing, the material is passed through vibrating screens with different mesh sizes. Each screen separates the aggregate into specific size fractions, such as coarse aggregate (gravel) and fine aggregate (sand).
4. Stockpiling: The sized aggregates are then stockpiled in separate bins or piles for easy access by the concrete batching plant.

Considerations for Setting Up a Crushing and Screening Plant

Before embarking on your crushing venture, here are some crucial factors to keep in mind:

• Production Capacity: Determine the amount of aggregate your concrete batching plant will require and size your crushing plant accordingly.
• Material Characteristics: The properties of your chosen raw material will influence the type of crushers and screens needed. For example, harder rocks might necessitate more powerful crushing machinery.
• Environmental Regulations: Ensure your plant complies with all environmental regulations regarding dust control and noise pollution.
• Permitting: Obtain the necessary permits for operating a crushing plant in your area.

Most Used Aggregates in Concrete Batching Plants

• Coarse Aggregate (Gravel): Typically ranges in size from 9.5 mm to 63 mm (⅜” to 2 ½”). Provides strength and stability to the concrete mix.
• Fine Aggregate (Sand): Generally falls within the range of 0.075 mm to 4.75 mm ( No. 200 sieve to ⅜”). Fills voids between coarse aggregate particles and contributes to workability.

Choosing the Best Raw Material for Concrete Production

The ideal raw material for concrete aggregates should possess the following characteristics:

• Strength: The aggregate should be strong and durable to withstand the stresses placed on concrete structures.
• Cleanliness: Free from contaminants like clay or organic material that can weaken the concrete bond.
• Shape: Angular-shaped aggregates create better interlocking, leading to stronger concrete.
• Grading: Consistent particle size distribution is crucial for optimal concrete properties.

Stockpiling Aggregates

Proper stockpiling practices ensure the consistent quality and availability of aggregates for the concrete batching plant. Here are some key points:

• Separate Stockpiles: Maintain separate stockpiles for each aggregate size to prevent mixing and ensure proper batching.
• Drainage: Ensure proper drainage to prevent stockpiles from becoming waterlogged, which can affect aggregate quality.
• Inventory Management: Implement a system to track inventory levels and prevent stockouts that could disrupt concrete production.

Operating a Crushing and Screening Plant

Operating a crushing and screening plant efficiently requires proper training and adherence to safety protocols. Here’s a glimpse into the key aspects:

• Equipment Maintenance: Regularly schedule maintenance for crushers, screens, and conveyors to prevent breakdowns and ensure optimal performance.
• Dust Control: Implement dust suppression measures to comply with regulations and create a safer working environment.
• Operator Training: Train plant operators on safe operation procedures, equipment functionality, and troubleshooting basic issues.

By understanding the process of obtaining aggregates, the crucial considerations for setting up a crushing plant, and the importance of proper operation, you can ensure a steady supply of high-quality aggregates for your concrete batching plant. This, in turn, translates to efficient concrete production and successful construction projects.

Production Quality

Crushing and screening plants for river materials often produce more homogeneous and uniformly shaped products. This is important in construction projects where more precise measurements and regulations are needed. On the other hand, the products obtained in mountain materials crushing and screening plants can often be more varied in size and coarser.

Operating Conditions

Mountain materials crushing and screening plants are often designed to withstand more demanding operating conditions. Crushing and conveying large rock fragments may require more intensive work. River materials crushing and screening plants, on the other hand, work with smaller and lighter materials, so operating conditions may be less challenging.

These differences are the main distinctions between a river materials crushing plant and a mountain materials crushing plant.

Each plant should be designed in a customized way according to the material properties and equipment should be selected to meet the needs.
