A simple ballast crushing machine in Kenya can be designed using basic mechanical principles to crush stones into ballast for construction and railway use. Here’s a basic concept:
Simple Ballast Crushing Machine Design
1. Primary Components:
– Jaw Crusher: A small, manually operated or motorized jaw crusher can crush large rocks into smaller pieces (50–150mm).
– Hammer Mill or Impact Crusher: Further crushes the stones into fine ballast (20–40mm).
– Vibrating Screen: Separates crushed ballast into desired sizes.
– Conveyor Belt (Optional): Transports crushed material.
2. Power Source:
– Manual Operation: For small-scale use (labor-intensive).
– Electric/Diesel Motor: For higher efficiency (5–15 HP motor).
3. Materials Needed:
– Steel frame
– Manganese steel jaws/hammers
– Bearings & shafts
– Mesh screens for sizing
– Bolts, nuts, and welding materials
4. Estimated Cost in Kenya:
– Small manual crusher: Ksh 50,000 – 150,000 (~$400 – $1,200)
– Motorized version: Ksh 200,000 – 500,000 (~$1,500 – $4,000)
5. Where to Buy/Assemble:
– Local fabricators in Nairobi, Mombasa, or Eldoret.
– Import from China (Alibaba) for pre-built machines.

Alternative Options
– Manual Stone Crushers: Cheaper but slower.
– Mobile Crushers: For on-site crushing (higher cost).
