Cone Crusher socket liner

The cone crusher socket liner, a replaceable wear-resistant component in the socket’s bearing cavity, acts as an interface between the rotating main shaft and stationary socket. It protects against wear, reduces friction (≤0.15 with lubrication), distributes loads, and compensates for minor misalignment, requiring good wear resistance and lubricant compatibility. Structurally, it is a cylindrical/flanged sleeve with a liner body (bronze, babbitt, or bimetallic materials), inner bearing surface (Ra0.8–1.6 μm with oil grooves), outer surface (interference fit), optional flange, lubrication features, and chamfers, with 5–15 mm wall thickness. Manufacturing involves casting (centrifugal/sand) for bronze liners, plus heat treatment and machining, or steel shell preparation, bearing layer application (sintering/roll bonding) and machining for bimetallic ones. Quality control includes material testing (composition, hardness), dimensional checks (CMM, roundness testing), microstructural analysis, performance tests (friction, wear), and fit checks, ensuring it protects components for efficient crusher operation

Cone Crusher socket

The cone crusher socket, a key component at the moving cone's bottom, functions as a pivot for the main shaft, transmits loads to the frame, facilitates lubrication, and maintains alignment. It operates under high loads, requiring strength, wear resistance, and precision. Structurally, it includes a high-strength alloy steel (42CrMo) body, a precision bearing cavity, eccentric bushing interface, lubrication channels, a mounting flange, and locating pins, with optional wear-resistant inserts. Manufacturing involves sand casting (pattern making, molding, melting/pouring), heat treatment (quenching/tempering, local hardening), and machining (precision boring, flange processing, channel drilling). Quality control covers material testing (composition, mechanics), dimensional checks (CMM, roundness testing), NDT (UT, MPT), mechanical tests (hardness, compression), and functional trials. These ensure it supports stable 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 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.
