30-50 TPH Granite Crushing Plant In Tanzania

Client Profile

A Tanzanian construction firm specializing in infrastructure development sought reliable sand-making equipment to process local granite into high-quality aggregates for road and building projects.

Project Overview

• Location: Tanzania
• Material: Hard granite (compressive strength 250-300MPa)
• Required Output: 30-50 tons per hour (TPH) of 0-5mm sand & 5-20mm aggregates
• Challenge: Granite’s abrasiveness demanded durable equipment with low maintenance costs.

Challenges

1. Hard Material Wear: Granite accelerates equipment wear.
2. Consistent Output: Needed stable production of uniformly graded sand.
3. Space Constraints: Compact footprint required for remote site.

Solution: Liming’s Granite Crushing Line

1. Primary Crushing: C6X Jaw Crusher

• Model: C6X125
• Role: Coarse crushing of 500mm granite blocks to ≤150mm.
• Advantages: Integral cast steel frame, wedge adjustment for granularity control.

2. Secondary Crushing: HPT Hydraulic Cone Crusher

• Model: HPT200
• Role: Further crushes ≤150mm granite to ≤30mm.
• Advantages: Multi-cylinder design for higher crushing efficiency, 30% longer liner lifespan.

3. Sand Making: VSI6X Sand Maker

• Model: VSI6X1263
• Role: Transforms ≤30mm feed into 0-5mm high-quality sand.
• Advantages: “Rock-on-rock” crushing reduces metal wear, PLC-controlled gradation.

4. Screening: S5X Vibrating Screen

• Model: S5X1860-3
• Role: Classifies outputs into 0-5mm sand and 5-20mm aggregates.
• Advantages: Rubber damping springs reduce noise by 25%.

Flowchart:
Granite → C6X Jaw Crusher → HPT Cone Crusher → VSI6X Sand Maker → S5X Screen → Final Products

Technical Highlights

• Intelligent Control: Centralized PLC system monitors production in real-time.
• Dust Suppression: Equipped with fog cannons for EPA compliance.
• Low Maintenance: HPT’s hydraulic clearing reduces downtime by 40%.

Results

• Output Achieved: 48TPH consistently (exceeding 50TPH peak).
• Product Quality: Sand with ≤3% needle content, meeting ASTM C33 standards.
• ROI: Payback period shortened to 8 months due to energy-efficient VSI6X.

Client Feedback

“Liming’s team configured the perfect line for our granite. The VSI6X’s sand shape boosted our concrete strength by 15%.”
