Kenya 100 TPH Granite Crushing Plant in Kisumu

100 TPH Granite Crushing Plant in Kisumu, Kenya

This case focuses on a 100 ton per hour (TPH) crushing and screening plant designed to process hard rock for the growing construction sector in Kisumu and the surrounding region.

Equipment and Process

The plant uses a three-stage process to efficiently produce high-quality aggregates. Its core components include:
Primary Crushing (Jaw Crusher - PE 600*900): The process begins with a vibrating feeder that sends the raw rock (up to 600mm) into a jaw crusher. This robust machine is responsible for the initial heavy breaking of the hard granite.

Secondary Crushing (Impact Crusher - PF1315): The crushed material is then sent to a secondary impact crusher. This stage further reduces the stone size and, crucially, shapes the particles into a cubical shape, which is highly valued in construction for its strength and stability.

Screening & Automation (Vibrating Screen & Automation System): A vibrating screen separates the material into four precise final products. An automation system is also integrated to allow for real-time monitoring and efficient operation.

Final Product Specifications

The plant is designed to produce four distinct, high-demand aggregate sizes for different construction applications:

• 0-6 mm: Fine aggregates for concrete production
• 6-10 mm: Asphalt and concrete mixes
• 10-14 mm: Road base and infrastructure filling
• 14-20 mm: Durable concrete and foundation materials

Considerations & Alternatives

Secondary Crusher Selection: Impact vs. Cone

The Kisumu case uses an Impact Crusher for its secondary stage, which is excellent for producing cubical-shaped aggregates ideal for concrete and asphalt.

Alternative: For purely high-volume production where particle shape is less critical, a Cone Crusher is often preferred for its high capacity and efficiency in processing hard, abrasive stone like granite.

Market Relevance

A 100 TPH plant is strategically sized for Kenya's market. It offers a balance between high productivity and practicality, making it suitable for medium-to-large infrastructure projects such as building roads, railways, and housing developments.

Equipment Costs

Based on general equipment listings, a full 100 TPH stationary crushing plant represents a significant capital investment. For a rough estimate, new equipment alone can range from $100,000 to over $400,000 USD, depending on the brand, the specific secondary crusher (impact vs. cone), and the level of automation included.
