An Example of Our Gyratory Crusher Concaves
Larger Concave Segments
The fewer concave segments you need to handle during relining, the faster you can get your gyratory crusher back online. Shengda Machine understands this operational value deeply, which is why we’ve engineered double-height, double-width, and dual-dimension (double height & width) concave segments for countless satisfied customers across the globe.
This design delivers tangible benefits to your operations:
- Streamlined ordering and replacement processes for enhanced efficiency
- Lower cost per pound of wear-resistant metal compared to smaller segments
- Reduced seam lines, which are typically the most vulnerable areas to severe wear
- Less backing material required for installation, cutting down on auxiliary costs and labor time
Thicker Concaves
Standard general-purpose concaves with uniform thickness often underperform, as wear patterns vary drastically across different applications. Our engineering team has verified that targeted thickness increases can double or even triple the service life of concave segments. To ensure secure installation, all our concaves are precision-machined with side grooves designed to accommodate spacer or keeper dowels.
Hard Facing
We offer proprietary wear-resistant overlays for select concave segments manufactured from our H or L series steels. Field feedback from our clients confirms dramatic improvements in wear life—with extensions of up to 100% in certain applications. This translates to dual benefits: you’ll cut costs on replacement wear metals, while simultaneously reducing labor expenses and equipment downtime associated with frequent part changeouts.
The overlay can be precisely applied to high-wear zones (such as areas beneath feeders), eliminating the need to replace an entire row of segments due to localized wear.
