50 TPH Limestone Crushing Plant In Tanzania

Customer Profile

Client: A construction materials supplier in Tanzania
Industry: Building materials & aggregates production
Location: Tanzania

Project Overview

The client needed a reliable 50-ton-per-hour (50TPH) limestone crushing and sand-making plant to produce high-quality aggregates for local construction projects. The primary material was medium-hard limestone, requiring efficient crushing, screening, and grading for optimal sand and gravel output.

Challenges

• Material Hardness: Limestone’s moderate abrasiveness required durable crushing equipment.
• Production Demand: Consistent 50TPH output to meet construction timelines.
• Site Conditions: Harsh working environment with dust and high temperatures.

Solution: Customized Crushing & Sand-Making Line

Liming Heavy Industry designed a complete limestone crushing and sand production line, including:

1. Primary Crushing – PE400×600 Jaw Crusher
   • High crushing ratio and sturdy structure for limestone initial breakdown.
   • Ensures stable feed size for secondary crushing.
2. Secondary Crushing – PF1010 Impact Crusher
   • Fine crushing for shaping aggregates with superior grain shape.
   • Energy-efficient operation, reducing particle size to 0-30mm.
3. Screening & Grading – 3YZS1548 Vibrating Screen
   • Three-deck screening for precise particle size control (0-5mm, 5-10mm, 10-20mm).
   • Low noise and high screening efficiency.
4. Optional Sand Making – VSI7611 Sand Maker (if fine sand required)
   • Produces high-quality 0-5mm artificial sand for concrete and asphalt.

Technical Highlights

• Automated Control: PLC system for real-time monitoring.
• Dust Suppression: Water spray system at transfer points.
• Energy Saving: Optimized motor and drive design.

Project Results

• Output: Achieved stable 50-55TPH, exceeding client expectations.
• Product Quality: Uniform sand and gravel, meeting Tanzania’s construction standards.
• Operational Cost: Low maintenance and energy consumption.
