Crushing Challenges
Extreme Hardness
Granite's Mohs 6–7 hardness places it at the upper limit of what standard crushers handle comfortably. Primary crushing demands a jaw crusher with a deep, reinforced crushing chamber and a high-powered motor to maintain consistent throughput without stalling under peak load.
Rapid Wear on Liners
The high silica content in granite is highly abrasive. Jaw plates, cone liners, and screen media wear significantly faster than on softer materials. Equipment selection and liner material grade directly affect operating costs - manganese steel grades and liner geometry must be matched to the feed size and reduction ratio.
High Impact Load
Run-of-mine granite often arrives in large, irregular blocks with sharp edges. The sudden impact loads during primary crushing create stress spikes in the crusher frame. A properly rated jaw crusher with a heavy flywheel absorbs these peaks and protects the drivetrain.

FAQ
Which Crusher Type is Best for Granite Primary Crushing?
A jaw crusher is the standard choice for granite primary crushing. Its compressive crushing action suits the hardness, and the simple chamber geometry is easy to maintain in quarry conditions. For very high capacities above 800 t/h, a gyratory crusher may be considered.
How Quickly do Wear Parts Wear out on Granite?
Faster than on most other materials. Jaw plate life on granite typically runs 300–600 operating hours depending on liner grade and feed size. We recommend keeping a spare set on site to avoid unplanned downtime. Our engineers can advise on the right liner specification for your specific granite source.
Can you Achieve Manufactured Sand (0–5mm) from Granite?
Yes. Granite is one of the most common materials for manufactured sand production. A VSI (vertical shaft impact) crusher in the third stage shapes the particles and produces a well-graded 0–5mm product that meets most concrete sand standards.
Can you Supply a Complete Turnkey Granite Crushing Line?
Yes. We supply everything from the primary jaw crusher through to final screening and stockpiling, including conveyors, feeders, and control systems. We also provide site layout, installation supervision, and commissioning support.
What is the Typical Power Consumption for a 300 t/h Granite Line?
A complete three-stage 300 t/h granite crushing and screening plant typically requires 500–700 kW of installed power, depending on the number of crushing stages and screen decks. We provide a full power and load analysis as part of the proposal.
