Industrial & Mining Applications

Optimized for processing high-hardness geological materials across demanding industrial sectors requiring high automation.

Aggregate & Sand Production

Processes abrasive river pebbles, granite, and basalt to supply reliable feed material for concrete batching and dry powder mortar plants.

Metallic Mine Extraction

Serves as a critical primary or secondary reduction stage for tough metallic ores, including iron, gold, and copper.

Industrial & Chemical Sectors

Provides precise size reduction of limestone and quartz sand essential for power plant desulfurization and refractory material manufacturing.

Coal & Specialized Mining

Adapts to harsh mining environments, utilizing advanced hydraulic systems to minimize downtime and maintain continuous extraction workflows.

Structural & Mechanical Advantages

Integral Cast Steel Bearing Housing

Replaces conventional two-piece designs with a single integral cast steel structure. This configuration eliminates unnecessary structural burden on main frames, significantly improving overall machine stability and operational reliability.

V-Shaped Crushing Cavity

Cavity geometry ensures actual feed opening width perfectly matches nominal dimensions, accommodating larger input sizes. Tooth-shaped guard plates increase effective jaw length, maximizing crushing area and preventing material blockages.

Hydraulic Wedge CSS Adjustment

Outdated shim plates are replaced by advanced wedge systems. Working in tandem with hydraulic controls, operators can adjust discharge settings to predetermined values within minutes, even while idling.

Dual Overload Protection Mechanisms

Toggle plates fracture intentionally to protect expensive components when uncrushable objects enter. Additionally, hydraulic cylinders feature overload protection; during overload events, relief valves discharge oil, forcing wedges outward to enlarge discharge gaps safely.

Hydraulic Cavity Clearing & Lubrication

Dedicated hydraulic oil stations ensure continuous lubrication to critical moving parts. If machines stall under heavy load, hydraulic cavity clearing systems rapidly evacuate trapped rock, drastically cutting maintenance downtime.

FEA & High-Strength Metallurgy

Developed utilizing Finite Element Analysis (FEA). Moving jaw assemblies utilize high-quality cast steel, while heavy-duty eccentric shafts are machined from forged blanks. This combination increases structural strength while optimizing total equipment mass.

How It Works On-Site

PEW Series Jaw Crusher
  • 1

    Motor & Pulley Transmission

    Electric motors provide continuous motive force, driving heavy-duty pulleys via V-belts. Rotational torque transfers directly into forged eccentric shafts.

  • 2

    Eccentric Kinematics

    Driven by eccentric shafts, moving jaws oscillate up, down, forward, and backward. This specific motion profile maximizes compressive force application against trapped rock.

  • 3

    Compressive Material Fracture

    As moving jaw plates push toward fixed jaw plates, V-shaped cavity volume shrinks. Materials undergo immense compressive and splitting forces, fracturing into smaller aggregate grades.

  • 4

    Spring-Assisted Discharge

    When eccentric shafts cycle backward, tension springs pull moving jaw plates away from fixed plates. Fragmented material drops through widened bottom openings via gravity.
