1. Hard rock crushing plant
Abstract:
Hard rock crushing plant is mainly used in crushing hard stones. It mainly consists of jaw crusher,
cone crusher, and vsi/vsi5x crusher, etc. Hard rock crushers have expanded stone crushing filed.
Hard rock crusher is widely used in crushing gold ore, iron ore, copper, etc.

HARD ROCK CRUSHERS
Hard Rock is the ultimate compressive strength of rock specimens under saturated humidity (the
specimen diameter of 7 ~ 10CM, same height and diameter) greater than 29.4 × 103kPa (such as
granite, diorite, basalt and other igneous rocks; iron nature, cemented calcareous conglomerate,
sandstone, limestone, argillaceous limestone, dolomite and other sedimentary rocks; gneiss,
quartzite, marble, slate and other metamorphic rocks), to abrasive wear parts is very high. Thus,
Hard Rock Crushing Plant design should be reasonable, taking into account not only the
investment costs broken item, also taking into account operating costs. The typical process is
currently broken: Jaw Crusher PE600*900 + two SMH hydraulic cone crusher. Hard Rock higher
silicon content, difficult broken, broken by a cone crusher a higher proportion of aniseed, so use
two cone crushers, feed production line capacity to make uniform efficiency.

2. HARD ROCK CRUSHING PLANT
Hard Rock applicable to hydropower, highway, urban construction and other industries, Hard
Rock Crushing Plant finished size can be combined and graded according to the different needs of
users. Hard Rock Crushing Plant basic process: hard rock evenly sent by the vibrating feeder
machine for coarse broken jaw broken by rough broken jaw broken after the material is fed by a
belt conveyor to the crushing cone crusher for further crushing, crushing after being transported
to the hard rock vibrating screen for screening, to the finished size requirements of material
handling by belt conveyor to the finished product stockpile; does not meet the size requirements
of the finished hard rock screen returns breaking or crushing cone crusher processing from
vibration, form a closed loop.
SBM HARD ROCK CRUSHING PLANT ADVANTAGES
High degree of automation in the jaw crusher and double hydraulic cone crusher is the major
equipment Hard Rock Crushing Plant, crushing rate, low operating cost, energy saving, uniform
particle size, particle shape is good, with reasonable level. This production line is mainly based on
rock hardness and customer requirements for product size to be, depending on the production
scene, SBM can provide customers with a comprehensive program of hard rock and technical
support process, but also the actual installation conditions designed to non-customers standard
supporting components.
