Cone Crusher Main Shaft

The cone crusher main shaft, a critical rotating component connecting the eccentric bushing to the moving cone, performs key functions such as power transmission (driving the moving cone's eccentric rotation), load bearing (withstanding axial and radial loads up to thousands of kilonewtons), eccentric motion guidance (maintaining the moving cone's orbital path), and structural alignment (ensuring concentricity between the moving and fixed cones). It requires exceptional tensile strength, fatigue resistance, and dimensional precision for operation at 500–1500 rpm. Structurally, it is a stepped, cylindrical or conical forged component consisting of the shaft body (high-strength alloy steel 42CrMo or 35CrNiMo with 100–500 mm diameter and 500–2000 mm length), upper cone mount, eccentric bushing interface, bearing journals, shoulders and keyways, and lubrication channels. The manufacturing process involves forging (billet heating to 1100–1200°C, open-die forging, precision forging) and heat treatment (quenching and tempering, local surface hardening). Its machining and manufacturing process includes rough machining, precision machining of critical features, lubrication channel drilling, balancing, and surface treatment. Quality control processes cover material and forging testing (chemical composition analysis, ultrasonic testing), dimensional accuracy checks (using CMM and laser alignment tool), mechanical property testing (hardness and tensile testing), non-destructive testing (MPT and eddy current testing), and functional testing (rotational and load testing). These processes ensure the main shaft achieves the required precision, strength, and reliability to drive the cone crusher's crushing motion in mining and aggregate processing applications

Cone Crusher Frame

The cone crusher frame, as the foundational structural component of the crusher, serves as the "backbone" with core functions including overall structural support (bearing the weight of all components and crushing forces up to thousands of tons), force transmission (distributing loads to the foundation), component positioning (providing precise mounting surfaces), and protective enclosure (housing internal components). It requires high rigidity, strength, and dimensional stability to withstand long-term heavy loads and dynamic impacts. Structurally, it is a large, heavy-duty casting or welded structure composed of the frame body (high-strength cast steel ZG35CrMo or welded low-alloy steel Q355B with 80–200 mm thick walls), bearing housing, eccentric bushing chamber, mounting flanges (base and upper flanges), reinforcing ribs (30–80 mm thick), lubrication and cooling channels, and inspection and access doors. For large and complex frames, the casting process involves material selection, pattern making (with 1.5–2.5% shrinkage allowances), molding (using resin-bonded sand), melting and pouring (controlled temperature and flow rate), and cooling and heat treatment (normalization and tempering). The machining and manufacturing process includes rough machining, bearing housing and chamber machining, flange and mounting surface machining, reinforcing rib and external surface machining, and surface treatment. Quality control processes cover material testing (chemical composition, tensile and impact testing), dimensional inspection (using CMM and laser scanning), non-destructive testing (UT and MPT), mechanical testing (hardness and load testing), and assembly and functional testing. These processes ensure the frame provides stability, reliability, and long service life for the crusher in heavy-duty applications.

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 Mantle

The cone crusher mantle, also known as the moving cone liner, is a critical wear-resistant component mounted on the outer surface of the moving cone, forming the rotating part of the crushing chamber. Its main functions include active crushing (rotating eccentrically with the bowl liner to reduce materials), wear protection (shielding the moving cone), material flow control (guiding materials through the crushing chamber via its tapered profile), and force distribution (ensuring even force distribution to minimize localized wear). It requires exceptional wear resistance (hardness ≥HRC 60), impact toughness (≥12 J/cm²), and dimensional stability. Structurally, it is a conical or frustoconical component consisting of the mantle body (high-chromium cast iron like Cr20–Cr26 or nickel-hard cast iron), outer wear profile (with 15°–30° taper angle, ribbed/grooved surfaces, and smooth transition zones), mounting features (conical inner surface, bolt flange, locking nut interface, locating keys), reinforcement ribs, and chamfered/rounded edges. The casting process 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), and heat treatment (solution annealing and austempering). The machining process includes rough machining, precision machining of the inner surface, mounting feature machining, outer profile finishing, and surface treatment. Quality control covers 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 validation (accelerated testing and field trials). These ensure the mantle achieves the required wear resistance, precision, and durability for efficient cone crusher operation in mining, quarrying, and aggregate processing
