Project Background
A large granite mine in Southeast Asia has adopted a Liming Heavy Industry NK300HS tire-mounted mobile crushing station as its core equipment. The plant processes hard rock materials with a hardness of up to 280 MPa and has a designed capacity of 200-250 t/h. The plant integrates an HST300 hydraulic cone crusher with an intelligent pre-screening system, enabling automated control of the entire process from primary crushing to finished product grading.
Technical Highlights
Modular Design: Utilizing the patented NK series mobile crusher structure, the crusher can be relocated within two hours without disassembling the main unit.
Intelligent Control: Equipped with a CMS central control system, it monitors crushing chamber pressure and power load in real time, automatically adjusting the discharge opening (10-25mm) and feed rate.
Wear-Resistant: The movable cone liner is made of Mn18Cr2 alloy, extending its lifespan by 40% compared to traditional materials.
Operational Results
- Productivity Target Achieved: Stable output of 220 tons/h of finished material for three consecutive months, exceeding design capacity by 10%.
- Cost Optimization: The mobile crusher can be directly deployed on-site, reducing material transportation costs by 30%.
- Environmental Compliance: Integrated pulse dust removal ensures dust emission concentrations below 15 mg/m³.
Market Value
This project has become a benchmark for Liming Heavy Industry in Southeast Asia, leading to the signing of five subsequent similar projects in the Philippines, Laos, and other countries, demonstrating the comprehensive advantages of its mobile crushing technology in hard rock mining.
