Hi-Pro Primary Jaw Crusher

4432 Hi-Pro Primary Jaw Crusher mounted on civil foundations at a 200 TPH Crushing Plant

Hi-Pro Series Primary Jaw Crushers are among the most advanced Crushers in the world. We have turned the conventional “Single Toggle” crushing technology upon its head with the unique “Inverted Toggle Plate” technology. Our crushers are Stronger, Require Less Maintenance and Last Much Longer.

Our Primary Jaw Crushers effectively incorporate the Strength and Economy of Double Toggle Jaw Crusher in a Single Toggle Machine.

High Quality Components

Only the highest quality components go inside our Primary Jaw Crushers. Intelligent Design and Precision Manufacturing ensure a Very High Uptime in our machinery.

Shaft: Massive AISI 4340 Forged Shaft, Hardened and Precision Ground to give a Long Life under extreme conditions

Flywheels: Cast Carbon Steel with Heavy Outer Rim ensure a smooth crushing action.

Bearings: Large Oversized Cylindrical Bore Spherical Roller Bearings manufactured by FAG, Germany

Main Frame and Pitman: Fabricated using Heavy Section Mild Steel Plates manufactured by SAIL, India.

Crushing Chamber: Completely lined with Easily Replaceable Wear Plates:

  • Jaw Plates: High Manganese Steel Castings with Machined Faces to ensure High Productivity, held in place by Easily Replaceable Clamping Bars and Wedges.
  • Cheek Plates: Two Piece Geometry for Easy Handling
  • Deflector Plate: Hardened Alloy Steel Casting for Additional Protection against Wear .

Hydraulic CSS Adjustment: Supplied as Standard in all Hi-Pro Series Primary Jaw Crushers.

Toggle Plate and Toggle Bearings: Machined and Hardened Castings. Lubrication Free Design.


Strong by Design

Owing to the unique inverted toggle technology, load distribution in our Primary Jaw Crusher substantially balanced. The absence of compressive stress in the main frame ensures a much higher fatigue life.

On the other hand, the main frame of a Conventional Jaw Crusher has to endure both compressive and tensile loads. This causes excessive stress at the lower portion of the side wall, often leading to failure


Very Low Jaw Plate Wear

The crushing stroke in our Primary Jaw Crushers has been optimized to ensure minimum slippage of material between the Jaw Plates.

The material to be crushed gets squarely compressed between the jaw plates, minimizing friction during crushing.

On the other hand, rubbing action is inherent in all Conventional Single Toggle Jaw Crushers. The crushing stroke pushes the material up and down against the fixed jaw plate leading to faster wear and greater fines generation.
