Crushing Machinery for Limestone Mines

Crushing operations in limestone mines mainly consist of a complete process: primary crushing, secondary and fine crushing, sand shaping and screening. Based on the low-to-medium hardness and easy-crushing nature of limestone, SBM Group provides complete equipment solutions suitable for mines of different scales.

1. Primary Crushing Equipment: Efficient Processing of Large Raw Ore

C6X Series Jaw CrusherIdeal for large-scale mine primary crushing. It features a V-shaped deep crushing chamber, with a feed size up to 1300 mm and a capacity of 300–1200 tph. Equipped with hydraulic cavity cleaning and automatic discharge adjustment, it is perfect as the primary crusher for large limestone mines.

PE / PEW Series Jaw CrushersThe mainstream choice for small and medium-sized mines. The PEW European hydraulic jaw crusher uses an integrated cast steel bearing housing and heavy eccentric shaft for high stability. It can crush large limestone to below 25 cm in one pass, ready for secondary and fine crushing.

HGT Series Gyratory CrusherThe top choice for extra-large mines. Feed size ranges from 0–1350 mm, with a capacity of 2000–9000 tph. It has a large-inclination long crushing surface and automatic hydraulic control, suitable for continuous production in super-large limestone mines.

2. Secondary & Fine Crushing Equipment: Precise Finished Product Size Control

CI5X Series Impact CrusherThe main machine for limestone secondary and fine crushing. With an involute crushing chamber, it produces excellent cubical-shaped finished products. Capacity ranges from 250–2000 tph. Full hydraulic operation and easy wear parts replacement make it ideal for high-quality aggregate production.

PFW Series European Impact CrusherDesigned with crescent blow bars for strong impact and good wear resistance. Three-chamber crushing ensures even discharge, with a capacity of 70–400 tph. Hydraulic opening enables efficient maintenance, suitable for secondary and fine crushing in small and medium mines.

HST / HPT Series Cone CrushersSuitable for hard or impure limestone. Using inter-particle crushing, they produce low needle-like and flaky materials. With hydraulic cavity clearing and overload protection, they run stably and meet high-standard aggregate production lines.

3. Sand Making & Shaping Equipment: High-Quality Manufactured Sand

VSI6X Series Vertical Shaft Impact CrusherCombines sand making and shaping functions with dual modes: rock-on-rock and rock-on-iron. It produces round, well-graded sand with a capacity of 100–580 tph, perfect for limestone manufactured sand for concrete batching plants and infrastructure projects.

4. Auxiliary & Mobile Equipment

F5X Vibrating Feeder & S5X Vibrating ScreenThe feeder ensures uniform feeding and pre-screening to remove soil. The screen provides accurate classification to guarantee qualified finished products.

K3 Series Mobile Crushing PlantModular design requires no installation and allows fast relocation. Integrated with jaw crusher, impact crusher and screening unit, it is ideal for scattered mining operations or emergency production.
