Best crushing machine for sandstone breaking
Sandstone is a medium-hard sedimentary rock with moderate compressive strength and clay impurities. Breaking it requires three key performance points: high feeding capacity for primary crushing, strong wear resistance for secondary and fine crushing, and good shaping for final aggregate grain shape.
Based on sandstone’s physical traits, Li Ming has developed three core machines for three-stage processing: C6X jaw crusher for primary crushing, HST/HPT cone crushers for medium and fine crushing, and VSI6X sand maker for shaping. We also offer wheeled mobile crushing plants and VU tower-type integrated systems, which work perfectly for both aggregate and manufactured sand production with reliable performance and low running costs.
1.Primary Crushing Stage
The C6X European-style jaw crusher is our standard primary breaker for large raw sandstone blocks. Its deep V-shaped crushing cavity can take sandstone lumps up to 1 meter across with a large crushing ratio. The moving jaw assembly uses heavy cast-weld construction. We upgraded high-manganese jaw plates to handle mild abrasion from sandstone mixed with mud, delivering a 30% longer service life than regular jaw crushers. It handles big rough stones and muddy rock steadily.
Paired with the F5X heavy-duty vibrating feeder fitted with bar screens, it sifts out surface clay from sandstone ahead of crushing. This stops mud from wearing down downstream machines and prevents blockages and clogged crushing chambers. Unit output ranges from 100 to 800 tons per hour, fitting production lines of all sizes.
2.Medium & Fine Crushing Stage
Pick the cone crusher based on rock hardness: use the HST single-cylinder hydraulic cone crusher for regular sandstone, and the HPT multi-cylinder hydraulic cone crusher for hard quartz sandstone.
Both crush sandstone via interparticle layer compression, producing material with few flaky pieces that meets crushing value standards for high-grade concrete.
The HST comes with an automatic hydraulic control system: operators adjust discharge size with one click, and an auto pressure relief system protects the machine if uncrushable metal or extra hard rock gets inside.
The HPT withstands heavier pressure for finer, more uniform crushed material. Its segmented modular wear liners let workers swap only worn sections instead of whole plates, cutting downtime for maintenance drastically.
A 2.5-million-ton annual quartz sandstone production line in Shandong runs stably all year with a C6X plus dual HST cone setup, suffering far fewer breakdowns than competing equipment combinations.
3.Sand Making & Shaping Stage
The VSI6X vertical shaft impact sand maker turns crushed sandstone rock into standard manufactured sand. It switches easily between two working modes: rock-on-rock mode for pure sand production with minimal wear, and rock-on-iron mode for heavy shaping to create round, well-graded sand grains.
Split peripheral guard plates can be flipped and reused, and modular rotor hammers get replaced individually. Overall costs for wear parts drop by 40%. An automatic hydraulic opening cover lets one worker carry out internal inspections and repairs alone. A circulating thin oil temperature control system supports nonstop full-load operation. It accepts feed material up to 80 mm in size, runs 60 to 640 tons per hour, and outputs premium 0–5 mm sand ideal for commercial concrete, dry-mix mortar and road base filling.
