Cone Crusher clamping ring

The cone crusher clamping ring, a key fastening component between the adjustment ring and lower frame, secures the concave and stabilizes the bowl assembly. It fixes the concave, locks adjustments, distributes loads, and enhances sealing, enduring high clamping forces and cyclic loads. Structurally, it includes a high-strength cast/forged steel ring body, precision clamping surface, bolt holes, lifting lugs, locating features, and reinforcement ribs, with optional wear-resistant coatings. Manufacturing involves sand casting (ZG35CrMo) or forging (35CrMo), followed by heat treatment, machining (CNC turning/grinding for precision), and surface treatment. Quality control covers material testing (composition, mechanics), dimensional checks (CMM, laser tracking), structural integrity tests (UT, MPT), mechanical performance trials (clamping force, fatigue), and assembly validation. These ensure it reliably secures components for consistent crusher operation in mining and aggregate processing.

Cone Crusher Concave

The cone crusher concave, also called the fixed cone liner or bowl liner, is a key wear-resistant component mounted on the inner surface of the bowl, forming the stationary part of the crushing chamber. Its main functions include material crushing (cooperating with the rotating mantle), wear protection (shielding the bowl), material flow guidance (via its inner profile), and product size control (influenced by inner geometry). It needs exceptional wear resistance (surface hardness ≥HRC 60), impact toughness (≥12 J/cm²), and structural integrity to withstand continuous material impact. Structurally, it is a segmented (3–8 pieces for large crushers) or one-piece conical component. It consists of concave segments/one-piece structure, a wear-resistant body (high-chromium cast iron Cr20–Cr26 or Ni-Hard 4), an inner wear profile (tapered design with 15°–30° angle, ribs/grooves, parallel sections), mounting features (dovetail tabs, clamping holes, locating pins), outer backing (in bimetallic designs), and top/bottom flanges. The casting process for high-chromium cast iron concaves involves material selection (Cr20Mo3 with controlled composition), pattern making (segmented patterns with shrinkage allowances), molding (resin-bonded sand mold with refractory wash), melting and pouring (induction furnace, controlled temperature and flow rate), and cooling and heat treatment (solution annealing and austempering). The machining process includes rough machining, mounting feature machining, inner profile finishing, segment assembly (for multi-piece designs), and surface treatment. Quality control processes cover material testing (chemical composition and metallographic analysis), mechanical property testing (hardness and impact testing), dimensional accuracy checks (CMM and laser scanner), non-destructive testing (UT and MPT), and wear performance validation (accelerated testing and field trials). These ensure the concave achieves the required wear resistance, precision, and durability for efficient, long-term crushing performance in mining, quarrying, and aggregate processing

Cone Crusher Bowl

The cone crusher bowl, also known as the fixed cone housing or concave frame, is a key structural component forming the stationary outer shell of the crushing chamber. Positioned above the eccentric bushing and surrounding the mantle, its main functions include providing structural support for the bowl liner, forming the crushing chamber with the mantle, distributing loads to the base frame, and containing materials to ensure efficient flow. It requires high mechanical strength, rigidity, and dimensional accuracy, typically made of high-strength cast steel or welded steel plates. Structurally, it is a large conical or cylindrical-frustoconical component with a hollow interior, consisting of the bowl body (high-strength cast steel like ZG35CrMo), bowl liner mounting interface (dovetail grooves, clamping flange), adjustment mechanism interface (threaded outer surface, guide slots), reinforcing ribs, discharge opening, and lubrication/inspection ports. The casting process for the bowl involves material selection (ZG35CrMo), pattern making (with shrinkage allowances), molding (resin-bonded sand mold), melting and pouring (controlled temperature and flow rate), and cooling with heat treatment (normalization and tempering). Its machining process includes rough machining, thread and guide feature machining, inner surface and mounting interface machining, flange and bolt hole machining, and surface treatment. Quality control processes cover material testing (chemical composition and tensile strength), dimensional accuracy checks (CMM and laser scanner), structural integrity testing (ultrasonic and magnetic particle testing), mechanical performance testing (hardness and load testing), and assembly/functional testing. These ensure the bowl has the required structural strength, precision, and reliability to withstand extreme crushing forces, enabling efficient long-term operation in mining and aggregate processing.

Cone Crusher Bowl liner

The cone crusher bowl liner, also known as the fixed cone liner or concave liner, is a wear-resistant component mounted on the inner surface of the upper frame or bowl, forming the stationary part of the crushing chamber. Its main functions include material crushing (cooperating with the moving cone liner to reduce materials), wear protection (shielding the upper frame), material guidance (ensuring uniform material distribution via its inner profile), and product size control (influencing particle size distribution through its inner profile). It requires exceptional wear resistance, impact toughness, and structural integrity, with a service life of 500–2000 hours depending on material hardness. Structurally, it is a conical or frustoconical component consisting of the liner body (high-chromium cast iron like Cr20–Cr26 or martensitic steel), inner wear profile (with parallel sections, stepped/grooved surfaces, and a 15°–30° taper angle), mounting features (dovetail grooves, bolt holes, locating pins), reinforcement ribs, and a top flange. The casting process of the bowl liner involves material selection (high-chromium cast iron Cr20Mo3), pattern making (with shrinkage allowances), molding (resin-bonded sand mold), melting and pouring (controlled temperature and flow rate), cooling and shakeout, and heat treatment (solution annealing and austempering). Its machining and manufacturing process includes rough machining, mounting feature machining, inner profile machining, and surface treatment. Quality control processes cover material testing (chemical composition and metallographic analysis), mechanical property testing (hardness and impact testing), dimensional accuracy checks (using CMM and laser scanner), non-destructive testing (ultrasonic and magnetic particle testing), and wear performance testing. These processes ensure the bowl liner has the required wear resistance, precision, and durabil

Cone Crusher Adjustment Gear

The cone crusher adjustment gear, a key part of the gap adjustment system, modifies the crushing gap between mantle and concave to control product size. Its functions include gap adjustment (converting rotation to vertical bowl movement), torque transmission, locking adjusted positions, and load distribution, requiring high strength and precise tooth geometry. Structurally, it is a ring-shaped component with a gear ring body (high-strength cast steel ZG42CrMo), external/internal teeth (module 8–20), mounting flange, optional threaded interface, lubrication channels, and locking features. Manufacturing involves sand casting (material selection, pattern making, molding, melting/pouring, heat treatment), machining (rough machining, tooth machining, thread/flange processing, drilling lubrication channels), and surface treatment (tooth carburizing, epoxy coating). Quality control includes material testing (composition, tensile strength), dimensional checks (CMM, gear measuring center), structural testing (UT, MPT), mechanical performance testing (hardness, load tests), and functional testing.
