Malaysia hosts several key players in stone grinding and aggregate production, such as Lafarge Malaysia, Hume Concrete, and Kuari Pati Sdn Bhd. These companies specialize in processing granite, limestone, and other hard rocks into high-quality aggregates for construction and infrastructure projects.
A modern stone processing line typically includes:
1. Primary Jaw Crusher: Breaks large rocks into smaller pieces (e.g., Feed size: ≤1,200mm, Output: 50–300mm).
2. Secondary Cone Crusher: Further reduces material size (e.g., Output: 20–60mm).
3. Tertiary Impact Crusher/VSI Sand Maker: Produces fine aggregates or manufactured sand (0–5mm).
4. Vibrating Screens: Classifies materials by size.
5. Sand Washer: Removes impurities for premium-grade sand.

Q1: What’s the lifespan of crusher wear parts?
A: Manganese steel jaws/cones last ~6–12 months under normal use, depending on material hardness.
Q2: How to control dust in crushing plants?
A: Use water spray systems or bag filters alongside enclosed conveyors.
