1. 프로젝트 배경: 말레이시아의 백운석 자원 및 시장 수요

Malaysia boasts significant dolomite deposits, primarily distributed in states such as Perak, Selangor, and Johor. The dolomite in these regions is characterized by high purity (CaO content 30-35%, MgO content 20-25%), dense structure, and hardness ranging from 3 to 4 on the Mohs scale, making it an ideal raw material for producing high-strength concrete aggregates, road base materials, and flux in steelmaking. With the Malaysian government’s continuous investment in infrastructure development under the 12th Malaysia Plan (2021-2025), the demand for high-quality dolomite aggregates has increased exponentially. Traditional fixed crushing plants, however, face insurmountable challenges in meeting this demand, including high upfront investment, long construction cycles, difficulty in adapting to scattered dolomite mining sites, and high transportation costs of raw ore.

The client, a well-established Malaysian mining enterprise specializing in dolomite extraction and processing, was confronted with these pain points. Its existing fixed crushing line had low production efficiency, high energy consumption, and poor mobility, making it unable to efficiently utilize scattered dolomite resources. Moreover, the uneven particle size of the final aggregates failed to meet the quality standards for high-grade construction projects. To address these issues, the client sought a flexible, efficient, and cost-effective crushing solution. After in-depth market research and technical communication, SBM's NK portable crusher plant stood out due to its superior mobility, high crushing efficiency, and intelligent control system, ultimately becoming the core equipment for the client’s new dolomite crushing line.
