How to make a flow chart of a crushing plant

Creating a flow chart for a crushing plant involves several steps that detail the stages from receiving raw material to producing the finished product. Here’s a simplified step-by-step guide:

1. Receive and Store Raw Material:

   • Start: Raw material reception
   • Process: Unloading raw materials onto the storage site
   • Output: Raw material storage

2. Primary Crushing:

   • Start: Raw material storage
   • Process: Transport raw materials to the primary crusher
   • Output: Primary crushed material

3. Screening:

   • Start: Primary crushed material
   • Process: Transfer primary crushed material to the screening unit
   • Output: Separated material (desired size and oversized material)

4. Secondary Crushing (for oversized material):

   • Start: Oversized material
   • Process: Transport oversized material to the secondary crusher
   • Output: Secondary crushed material

5. Secondary Screening:

   • Start: Secondary crushed material
   • Process: Re-screening for further size refinement
   • Output: Finished product & Recycle material (if necessary)

6. Stacking / Stockpiling:

   • Start: Finished product from screening
   • Process: Transport finished product to the stockpile area
   • Output: Sorted final product (ready for shipment/use)

7. Transport (optional, based on the setup and requirements):

   • Start: Stockpiled product
   • Process: Load finished product for shipping
   • Output: Dispatched product

A visual representation of the flow chart is often more effective, where you use shapes like rectangles for processes, diamonds for decision points, and arrows to indicate the flow direction. Here’s a quick text-based representation to help you visualize:

\[Raw Material Reception\] --> \[Storage Site\]
        |
        v
\[Primary Crusher\] --> \[Screening Unit\]
        |                  |
     Primary          Desired Size
    Crushed Material         |
            v                v
   \[Secondary Crusher\]  \[Finished Product\] --> \[Stockpile / Stacking\]
           v
\[Secondary Crushed Material\] --> \[Secondary Screening Unit\]         

In creating a digital flow chart, tools like Microsoft Visio, Lucidchart, or even PowerPoint can be very helpful. Ensure to label each process clearly and use standardized symbols for different actions and decisions.
