Hard rock, including basalt, granite and diabase, is a core raw material for infrastructure, mining and cement industries. With high Mohs hardness (6-8), strong abrasiveness and poor toughness, it brings great challenges to crushing. Choosing the right hard rock crusher directly determines production efficiency, product quality and enterprise competitiveness. This guide highlights key selection points and reliable solutions.

Three core factors affect selection: material characteristics (different hard rocks require different crusher performance), production demand (hourly output and finished product specifications), and cost control (investment, maintenance and energy consumption).

In the global market, jaw crushers and sand making machines are core equipment for hard rock crushing. Westlakemachinery,a professional manufacturer, has won trust in over 100 countries with advanced technology and perfect services.

Westlakemachinery’s jaw crusher is designed for hard rock: super wear-resistant (high-chromium alloy parts, 1.5-2x longer service life), high efficiency (deep cavity design, crushing ratio 6-10, handles 1500mm raw rock), and easy to operate (adjust discharge size without stopping).

Its sand making machine is ideal for hard rock shaping, adopting "stone-on-stone" and "stone-on-iron" principles. It produces cubic finished products (needle content <5%) with 30% higher output and 20-30% lower energy consumption than ordinary models.
