A stone crushing plant with a capacity of 80-100 tons per hour (TPH) is a facility designed to crush stones, rocks, or similar materials into aggregates of various sizes for use in construction, road building, concrete production, and other industrial applications. This plant is suitable for medium-scale projects and can be set up as either a stationary or mobile facility. Stone crushing plants are widely used not only for aggregate production but also in mining operations.

Working Principle:

  1. Feeding:

    • Stone or rock material is fed into the crushing plant using an excavator, loader, or feeder. The feeding process ensures a consistent flow of material to the crusher.

  2. Primary Crushing:

    • The fed material is sent to a primary crusher (usually a jaw crusher or impact crusher). In this stage, large-sized stones are broken down into smaller pieces. For example, stones of 600-800 mm are reduced to 100-150 mm.

  3. Secondary Crushing:

    • After primary crushing, the material is sent to a secondary crusher (usually a cone crusher or impact crusher). Here, the material is further reduced to the desired sizes. For example, 100-150 mm material is reduced to 20-40 mm.

  4. Tertiary Crushing (If Required):

    • If finer aggregates are needed, a tertiary crusher is used. In this stage, the material is crushed to very small sizes, such as 0-5 mm or 5-12 mm.

  5. Screening:

    • The crushed material is passed through vibrating screens to separate it into different sizes. Screens classify the material into fractions like 0-5 mm, 5-12 mm, 12-25 mm, and 25-50 mm. This process ensures the aggregates are sorted according to their intended use.

  6. Stockpiling and Transportation:

    • After screening, the aggregates of different sizes are stored in stockpiles or directly loaded onto trucks for transportation to the construction site.

Features of the Plant:

  • Capacity: Processes 80-100 tons of material per hour.

  • Crusher Types: Jaw crusher, impact crusher, cone crusher, or tertiary crusher can be used.

  • Screening System: Vibrating screens are used for material classification.

  • Stationary or Mobile: Can be set up as either a stationary or mobile plant.

  • Automation: Modern plants are controlled by automation systems.

  • Eco-Friendly: Equipped with dust control systems and noise reduction measures.
