250-500 TPH Limestone Crushing Plant in Kenya

Client Background

The client is a mining and construction company based in Kenya, specializing in high-quality construction aggregates for infrastructure projects. They needed a reliable and high-capacity limestone crushing plant to meet their production demands of 250-500 tons per hour (TPH) for road construction and concrete production.

Project Overview

Liming Heavy Industry was selected to design and supply a complete turnkey limestone crushing and screening plant for the Kenyan client. The project required high efficiency, durability, and low operational costs, with strict output size control to meet construction standards.

Challenges:

• Material: Medium-hard limestone (compressive strength ~150MPa)
• Capacity Requirement: 250-500 TPH
• Final Products:
  • 0-5mm (fine sand for concrete)
  • 5-20mm (aggregate for road base)
  • 20-40mm (coarse construction stone)
• Key Constraints:
  • Limited maintenance expertise locally
  • High dust emission concerns
  • Need for reliable, energy-efficient equipment
