180-220 tph Stone Crusher Plant

Process Introduction

200tph stone crusher plant is a stationary stone crushing and screening plant. It could be customized to two stage crushing process or three stage crushing plant. The main machines includes: jaw crusher , cone crusher , or impact crusher, vibrating screen and belt conveyors.  It could manufacture of aggregates (coarse aggregates, crusher run, rock sand, fine aggregates) from limestone, granite, andesite, etc. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making. Fine aggregates are used for the production of concrete and plastering.

Crushing Process Introduction

Feeding
The excavator pours the raw materials into the silo, and the vibrating feeder evenly transports them to the jaw crusher.

Coarse crushing stage
The jaw crusher crushes the raw materials to ≤150mm, and transports them to the transfer yard or directly to the medium crushing through a belt conveyor.

Fine crushing stage
The cone crusher further crushes the coarse aggregate to produce the materials we want. After screening, the oversized materials return to the cone crusher.

Screening and finished product classification
The vibrating screen divides the materials into 4 specifications:
0-5mm (machine-made sand), 5-10mm (fine aggregate), 10-20mm (medium aggregate), 20-40mm (return to crushing)

Process advantages

• Ultra-high productivity and stable operation:
  Hydraulic + mechanical double overload protection system；Key components life (spindle ≥ 100,000 hours, bearing ≥ 50,000 hours)
• Intelligent control system:
  Remote operation and maintenance platform (real-time monitoring of 20+ parameters)；Automatic warning: automatic speed reduction when vibration value >4mm/s
• Military-grade wear-resistant configuration:
  Cone breaker liner: high chrome cast iron + tungsten carbide composite layer (life 3800 hours)；Jaw plate: isothermal quenching high manganese steel (hardness HB380-450)
• Green environmental protection design:
  Fully enclosed structure + negative pressure dust removal (dust <10mg/m³)；Noise control: factory boundary daytime <60dB (with acoustic enclosure)
