Granite is a hard igneous rock with Mohs hardness 6-7 and compressive strength 100-300MPa, featuring high silica content and strong abrasiveness. Ordinary stone crushers suffer fast wear of spare parts, insufficient output and poor aggregate shape when processing granite. Professional granite crusher machine adopts interparticle laminated crushing technology and high wear-resistant alloy wear parts, specially designed for raw granite ore, quarry waste granite and demolition granite residues. It can stably produce cuboid aggregate and high-quality manufactured sand, widely applied in highway construction, bridge engineering, concrete batching plant, railway ballast, infrastructure building and landscaping aggregate processing.1. Main Types of Granite Crusher & Application
(1) Jaw Crusher for Granite – Primary Crushing Core Equipment
Jaw granite crusher is the standard primary crushing machine in complete granite crushing plant. Its large feeding opening can directly handle granite boulders over 1m, with deep crushing cavity without dead zone for high reduction ratio. The fixed and movable jaw plates are made of high manganese steel, perfectly matching the severe abrasion of granite. PE and PEX series jaw granite crushers cover hourly capacity from 50t/h to 1200t/h, with simple structure and low failure rate. It is essential quarry granite crushing equipment for long-term stable primary crushing operations.
(2) Hydraulic Cone Granite Crusher – Optimal Secondary & Tertiary Crushing Machine
For high-hardness granite processing, hydraulic cone granite crusher applies laminated crushing principle: materials grind and extrude against each other, greatly reducing blow bar wear compared with impact crusher. The finished granite aggregate owns low flaky particle content and standard cuboid shape, meeting aggregate requirements of high-grade concrete and highway pavement. Single-cylinder & multi-cylinder hydraulic cone granite crushers equip automatic overload hydraulic protection, which retracts instantly to prevent damage when unbreakable iron blocks enter the cavity. Discharge size can be adjusted precisely via hydraulic system, ideal for producing 10-50mm granite crushed stone in medium & large granite aggregate production lines.
(3) Mobile Granite Crushing Station – Portable On-site Crushing Equipment
Tracked and wheeled mobile granite crushing plant integrates primary crusher, secondary crusher, vibrating screen and conveyor as one set. No fixed factory foundation is required; the whole unit can directly move to quarries or demolition sites for granite crushing on location, cutting huge raw material transportation costs. It is divided into mobile jaw crushing station, mobile cone crushing station and mobile sand making integrated machine, freely combined to form portable granite crushing line with 50-400t/h flexible capacity, suitable for frequently changed construction sites, small quarries and temporary engineering stone processing projects.
(4) VSI Granite Sand Making Machine – Shaping Equipment for Fine Manufactured Sand
Granite crushed stones after jaw & cone crushing enter VSI granite sand making machine for fine crushing and shaping, producing 0-5mm high-quality granite manufactured sand with round uniform grading. It solves the problem of sharp edges and unbalanced powder content of raw granite aggregate. Matched with washing and screening machines, the complete granite crushing & sand making plant can produce aggregate and manufactured sand simultaneously.
2. Standard Flow of Complete Granite Crushing Plant
Full granite aggregate processing workflow: Raw material bin → vibrating feeder → jaw granite crusher (primary crushing) → belt conveyor → hydraulic cone granite crusher (secondary crushing) → multi-layer vibrating screen for grading → qualified aggregate stockpile, oversized materials return for re-crushing. If sand production is needed, screened materials are sent to granite sand making machine, matched with dust removal system for eco-friendly production.Common configurations: 100tph, 200tph, 300tph complete granite crushing plant. Manufacturers provide free 3D production line layout design according to different quarry terrain conditions.

5. Tips to Choose Suitable Granite Crusher
Distinguish primary & secondary crushing demands first: Select jaw granite crusher for large raw boulders primary crushing, hydraulic cone crusher is a must for secondary fine crushing;
Choose mobile granite crushing station if limited site space or short-term construction projects;
Match budget and output: Small 50-150tph line matches single jaw crusher + small cone crusher; 200tph+ large-scale production line equips multi-cylinder hydraulic cone crusher;
Cooperate with professional granite crusher manufacturer instead of middlemen, guaranteeing machine quality, export packaging and customs clearance supporting service.
