Weathered Rock Expert: Technical FAQ
Q1: How can the Double-Roll Crusher achieve 50mm to 3mm in a single pass?
Weathered rock has a naturally fractured internal structure. HSM’s hydraulic system applies consistent, high-torque pressure that exploits these internal cleavage planes. Because of the high reduction ratio provided by the inter-particle crushing principle, a single pass replaces the multi-stage circuits required by traditional impact or cone crushers.
Q2: What happens if the weathered rock is wet or contains high clay content?
This is where our design excels. Traditional sand makers (VSI crushers) rely on bottom screens that clog instantly with sticky materials. HSM crushers feature a screen-free bottom and use gravity-assisted discharge. Material falls directly through after crushing, ensuring 24/7 operation even in rainy seasons or with high-moisture feed.
Q3: How does the output grain shape compare to VSI sand makers?
Actually, it’s often superior for weathered rock. Because the material fractures along its natural planes under compression, the resulting sand is highly cubical and rounded with very low needle-flake content. This improves the binding properties of the aggregate, making it highly sought after for high-grade concrete production.
