A gabbro crushing and screening plant with a capacity of 100-150 tons per hour (TPH) is a facility designed to process hard and durable rocks like gabbro into aggregates of various sizes. Gabbro is a high-strength material commonly used in construction, road building, concrete production, and other industrial applications. This plant is suitable for large-scale projects and is typically set up as a stationary facility.

Working Principle:

  1. Feeding:

    • Gabbro 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 gabbro rocks are broken down into smaller pieces. For example, gabbro of 600-800 mm is 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 100-150 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: Typically set up as a stationary plant, but mobile versions are also available.

  • Automation: Modern plants are controlled by automation systems.

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