Essential Equipment for 700tph Stone Crushing Plant

Establishing an efficient stone crushing plant is vital in the mining industry, especially when dealing with a 700 tons per hour (tph) mountain stones crushing plant. This facility requires specialized equipment tailored to meet the demands of crushing hard materials while ensuring operational efficiency and safety. This blog post will delve into the necessary equipment for such a plant and provide insights on designing an effective flow chart.

 

Understanding Mountain Stone Crushing

Mountain stones, including granite, basalt, limestone, and other hard rocks, are essential in various construction and infrastructure development projects. Crushing these stones into small, usable aggregates requires careful equipment selection to optimize efficiency, productivity, and safety standards.

Key Considerations for Crushing Plants

Before we explore the specific equipment needed, it’s essential to consider several factors that influence the design and operational efficiency of the crushing plant:

• Material Characteristics: Different types of stones exhibit varying hardness, density, and abrasiveness. Understanding these properties is crucial for selecting the right machinery. For example, granite is more solid than limestone, necessitating different crushing techniques and equipment.
• Production Goals: Clearly defining aggregates’ desired output size and quality is vital. The market demand often dictates the specifications, such as the required gradation of the crushed material.
• Site Conditions: The geographical and logistical aspects can impact equipment selection and layout. We should also consider factors such as access to raw materials, transportation routes, and environmental regulations.
• Regulatory Compliance: Ensure that the selected equipment meets local regulations like noise, emissions, and safety standards.

 

Essential Equipment for 700tph Stone Crushing Plant

Various equipment is necessary to run a 700tph mountain stone crushing plant efficiently. Below is a detailed breakdown of the key components:

1. Jaw Crusher

Function: The jaw crusher is the primary machine for crushing large boulders into manageable sizes.

Features:

• High crushing ratio (typically between 4:1 to 6:1)
• Adjustable discharge size to meet specifications
• Robust construction, suitable for harsh environments
• Recommended Models: Look for models that can handle feed sizes of up to 1,000mm and have a high throughput capacity.

2. Impact Crusher

Function: The impact crusher is used for secondary crushing, further reducing the size of the material while shaping the aggregate.

Features:

• High efficiency and low operational costs
• Ability to produce a variety of aggregate sizes
• Simple maintenance and operation
• Recommended Models: Choose from horizontal shaft impact (HSI) or vertical shaft impact (VSI) crushers.

3. Cone Crusher

Function: Ideal for tertiary crushing, the cone crusher is designed to produce finely crushed aggregates.

Features:

• High productivity and excellent particle shape
• Easy to adjust for different sizes and types of materials
• Designed for high-capacity applications
• Recommended Models: Opt for models with a high reduction ratio and a capacity that meets the 700tph requirement.

4. Vibrating Feeder

Function: It ensures a steady flow of materials into the crushers, preventing overload and ensuring optimal performance.

Features:

• Adjustable feed rate for efficiency
• Durable construction to handle heavy loads
• Can be equipped with a grizzly for preliminary screening
• Recommendation: Use electromagnetic or mechanical feeders based on your operational needs and site conditions.

5. Screening Equipment

Function: Screening equipment separates the material into different sizes for various applications, ensuring the end product meets the required specifications.

Types:

• Vibrating Screens: Effective for separating and classifying materials based on size.
• Trommel Screens: Screening wet sticky materials, providing thorough separation.
• Recommendation: Ensure the screens have multiple decks for effective sorting and are suitable for the intended material characteristics.

6. Belt Conveyors

Function: Belt conveyors transport materials between different stages of the crushing process, facilitating the movement of crushed stone to storage or further processing.

Features:

• Available in various lengths and widths to accommodate different layouts
• Adjustable speed settings to optimize material flow
• Equip with side walls or cleats to prevent spillage
• Recommendation: Choose heavy-duty conveyors to support the 700tph capacity.

7. Dust Suppression Systems

Function: Dust suppression systems are essential for controlling emissions, ensuring a cleaner working environment, and compliance with environmental regulations.

Options:

• Water sprays to minimize airborne dust
• Mix chemical dust suppressants with water for enhanced effectiveness
• Recommendation: Implement a comprehensive dust management strategy to maintain air quality and worker safety.

8. Control Systems

Function: Advanced control systems monitor and control the crushing process, ensuring optimal performance and safety.

Features:

• Automation capabilities for real-time monitoring
• Data collection for performance analysis and optimization
• User-friendly interfaces for easy operation
• Recommendation: Invest in a robust control system that integrates with all equipment for seamless operations.

9. Maintenance Tools and Equipment

Function: Maintenance tools are necessary to keep all machinery in optimal working condition, reducing downtime and extending equipment life.

Recommendation: Include essential tools for lubrication, repair kits, and diagnostic devices to facilitate quick maintenance and troubleshooting.

 

Designing the Flow Chart for 700tph Crushing Plant

Creating an efficient flow chart is critical for visualizing the layout and operational workflow of the stone crushing plant. Below are the steps to design an effective flow chart:

Step 1: Identify the Process Stages

The primary stages in a mountain stones crushing plant include:

Material Arrival: Raw materials arrive via truck or conveyor.

• Primary Crushing (Jaw Crusher): Crushing large boulders to small size.
• Secondary Crushing (Impact Crusher): Further size reduction and shaping of aggregates.
• Tertiary Crushing (Cone Crusher): Producing finely crushed materials.
• Screening: Separating crushed materials into different sizes.
• Transportation (Belt Conveyors): Moving materials to storage or delivery points.
• Stockpile or Delivery: Finished products are stored or dispatched.

Step 2: Flow Chart Layout

Start with Material Input: Indicate where the mountain stones arrive at the plant.

Sequence the Crushing Stages: Use arrows to show the flow from one stage to the next (e.g., from Jaw Crusher to Impact Crusher).

Include Screening and Conveying: Depict how crushed materials are sorted and transported.

End with Output: Show where and how the finished products are stored or dispatched.

Sample Flow Chart

Step 3: Consider Feedback Loops

Incorporate feedback loops for material that may require re-crushing or additional screening. It can enhance the efficiency and reduce waste.

Step 4: Optimize Layout for Space and Efficiency

Ensure that equipment minimizes material handling and maximizes workflow.

Incorporate maintenance access and safety protocols into your design to ensure easy servicing.

 

Conclusion

Establishing a 700tph mountain stones crushing plant requires careful planning, suitable equipment, and a well-designed flow chart. By understanding the specific needs of your operation and selecting the appropriate machinery, you can ensure efficiency and productivity in your crushing process. This knowledge is crucial for meeting the demands of the construction industry and achieving operational excellence.

In summary, the success of a crushing plant hinges on the synergy between the selected equipment, efficient layout, and effective operational strategies.
