stone crusher for sale

Here's a simplified process diagram of a stone crusher in India:

 

    Raw Materials: The process begins with the extraction of raw materials from a quarry or mine. Common raw materials used for stone crushing in India include limestone, granite, dolomite, traprock, sandstone, quartz, and various types of rocks.

 

    Feeding: The extracted raw materials are transported to a primary crusher by heavy-duty trucks or loaders. The primary crusher, usually a jaw crusher, receives the raw materials and reduces their size to smaller fragments.

 

    Crushing: The primary crusher further breaks down the raw materials into smaller pieces. The crushed materials may pass through multiple stages of crushers, depending on the desired size and the characteristics of the stone. Common types of secondary crushers used in India are cone crushers, impact crushers, and gyratory crushers.

 

    Screening: After the crushing process, the crushed stones are screened to separate them into different sizes. Vibrating screens or rotary screens are commonly used for this purpose. The screened stones are categorized into different grades based on their size.

 

    Conveying and Storage: The graded stones are then conveyed to storage areas or stockpiles. This is typically done using conveyor belts, which transport the stones from the screening stage to the storage area.

 

    Crushing Plant: In some cases, the process may involve multiple stages of crushing. A stone crushing plant may include one or more secondary crushers, tertiary crushers, and even quaternary crushers, depending on the final desired product size. Each crusher in the plant is responsible for reducing the size of the stones further.

 

Screening and Washing: In addition to screening after crushing, some stone crushing plants may also include washing processes. This is done to remove any dust, fines, or impurities from the crushed stones. Various types of screens, such as inclined screens or rotary screens, can be used for this purpose. Additionally, washing equipment like sand classifiers or screw washers can be employed.
