250-300 TPH Granite Crushing Plant in Guyana

Client Overview

Our client in Guyana operates a large-scale quarry specializing in high-quality granite aggregates for construction and infrastructure projects. They needed a reliable crushing plant to produce 250-300 tons of sand and gravel per hour for road and building material applications.

Project Overview

• Location: Guyana, South America
• Material: Hard granite (compressive strength: 150-200 MPa)
• Required Output: 250-300 TPH
• Final Products: 0-5mm, 5-10mm, 10-20mm, and 20-40mm aggregates for construction.

Challenges

1. Hard Material Processing – Granite is abrasive and requires robust crushing equipment.
2. High Production Demand – The plant must maintain steady output at 250-300 TPH.
3. Strict Gradation Requirements – Multiple final specs for different applications.
4. Dust & Noise Control – Compliance with environmental regulations.

Solution by Liming Heavy Industry
