Multi-cylinder Hydraulic Cone Crusher

The multi-cylinder hydraulic cone crusher, an advanced equipment for medium-to-fine crushing of hard/ultra-hard materials (granite, basalt, etc.), utilizes "lamination crushing" technology. Driven by a motor, its eccentric shaft sleeve rotates to make the moving cone oscillate, crushing materials between the moving and fixed cones into uniform particles, with a capacity of 50–2000 t/h, widely used in mining, construction aggregates, etc. Structurally, it includes: main frame assembly (upper frame ZG270-500, lower frame ZG35CrMo); crushing assembly (42CrMo moving cone with Cr20/ZGMn13 liner, segmented fixed cone); transmission assembly (ZG35CrMo eccentric shaft sleeve, 20CrMnTi bevel gears); 6–12 hydraulic cylinders for discharge port adjustment (5–50 mm) and overload protection; plus lubrication (ISO VG 46 oil) and dustproof systems. Key components undergo precise manufacturing: casting (frames, eccentric sleeve) with heat treatment; forging (moving cone) and CNC machining. Quality control involves material testing (spectrometry, tensile tests), dimensional inspection (CMM, laser scanning), NDT (UT, MPT), and performance tests (dynamic balancing, 48-hour crushing run). Its advantages lie in high efficiency, excellent product cubicity (≥85%), reliable hydraulic safety, and adaptability to tough materials, serving as core equipment in modern crushing lines

Single Cylinder Hydraulic Cone Crusher

a. High efficiency: The hydraulic cone crusher has supports at the upper and lower ends of the main shaft, which can withstand greater crushing force and greater stroke, and the special crushing cavity shape compatible with the lamination principle makes the machine more High crushing efficiency. b. Large production capacity: The hydraulic cone crusher is designed with a perfect combination of crushing stroke, crushing speed and crushing cavity shape, so that the output of the machine is 35% ~60% higher than that of the old spring cone crusher when the diameter of the large end of the moving cone is the same. c. High-quality stones: The hydraulic cone crusher adopts the unique shape of the crushing cavity and the principle of lamination crushing to produce the crushing effect between particles, so that the proportion of cubes in the finished product is significantly increased, the needle-shaped stones are reduced, and the particles are reduced. The level is more uniform. d. The medium and fine crushing of various cavity shapes can be realized by only replacing the fixed cone. e. The hydraulic and lubrication system controlled by double insurance can ensure the overload protection of the machine and good bearing lubrication. f. Easy to maintain: the cone crusher has a simple and compact structure, stable performance and not easy to malfunction. Maintenance is convenient and quick.

Gyratory Crusher

The gyratory crusher is a large-scale primary crushing equipment widely used in mining and metallurgy. It features a vertical spindle with a conical crushing head that gyrates within a fixed concave, forming a crushing cavity. Its structure includes a heavy-duty frame, a rotating main shaft, an eccentric sleeve, a crushing cone, and a fixed cone. The main shaft, driven by a motor via gears, gyrates to make the crushing cone oscillate, squeezing and breaking materials between the cone and concave. Advantages include high throughput, continuous operation, and suitability for crushing large, hard ores (up to several meters in diameter). It offers stable performance and low maintenance, making it ideal for primary crushing stages in large-scale mineral processing plants

Compound Cone Crusher

The compound cone crusher, a multi-cavity advanced crusher for medium-to-fine crushing of hard materials, integrates spring and hydraulic cone crusher advantages. Its 2–4 stage crushing cavities enable gradual material reduction via lamination crushing, ensuring uniform particle sizes with high cubicity. Structurally, it comprises key assemblies: a heavy-duty cast steel main frame (ZG270-500) supporting components; a crushing assembly with a 42CrMo forged movable cone (manganese steel/high-chromium liner) and multi-section fixed cone; a transmission system with a ZG35CrMo eccentric shaft sleeve and 20CrMnTi bevel gears; hydraulic adjustment (5–50 mm discharge port) and safety systems; plus dustproof (labyrinth seal, air purge) and lubrication setups. Manufacturing involves precision casting (frame, eccentric sleeve) and forging (movable cone, main shaft) with heat treatment, followed by CNC machining for tight tolerances. Quality control includes material testing, dimensional inspection (CMM, laser scanning), NDT (UT, MPT), and performance tests (dynamic balancing, 24-hour crushing runs). Its advantages lie in high efficiency, compact design, adjustable stages, and reliable safety, suiting mining, construction, and aggregate processing

Spring Cone Crusher

The Symons cone crusher, an upgraded replacement for PY series spring cone crushers, features a spring safety system as an over-protection device, allowing metal foreign bodies to pass through the crushing cavity without damaging the machine. It adopts dry oil sealing to isolate stone powder from lubricating oil, ensuring reliable operation, and is widely used in industries such as mining, cement production, construction, and metallurgy for crushing ores (metal, non-metal, ferrous, non-ferrous), lime, limestone, quartzite, sandstone, and pebbles. Its working mechanism comprises a crushing cone (with a manganese steel liner) and a fixed cone (adjustment ring), with zinc alloy poured between the liner and cone for tight integration. The crushing cone is press-fitted on the main shaft, whose lower end fits into the tapered hole of an eccentric shaft sleeve (with bronze or MC-6 nylon bushings). Rotation of the eccentric shaft sleeve via bevel gears drives the main shaft and crushing cone (supported by a spherical bearing) to swing, achieving ore crushing.

Cone Crusher step plate

The cone crusher step plate (main shaft step plate) is a key load-bearing and structural component, primarily responsible for axial load transmission (handling several tons in medium-sized crushers), positioning/guiding the main shaft and moving cone, and providing mechanical support to reduce vibration. Structurally, it is a disc-shaped part made of high-strength alloy steel (40CrNiMoA/35CrMo) with a 30–80 mm thickness. It features a central hole (±0.05 mm tolerance) for main shaft fit, step features (10–30 mm height, 20–50 mm width) interacting with thrust bearings, and 8–24 mounting holes for high-strength bolts (grade 8.8+). Manufacturing involves: Casting: Alloy steel melting (1500–1550°C), sand mold casting, followed by normalization (850–900°C) and quenching-tempering (820–860°C quenching, 500–600°C tempering). Machining: Rough turning (2–3 mm allowance), precision grinding (Ra0.8–1.6 μm surface finish, ±0.02 mm dimensional tolerance), and drilling/tapping (±0.1 mm positional tolerance for holes). Surface treatment: Shot-blasting and anti-rust coating (80–120 μm). Quality control includes material testing (chemical composition, tensile strength ≥980 MPa for 40CrNiMoA), dimensional inspection (CMM and gauges), NDT (ultrasonic/magnetic particle testing for defects), and assembly/performance validation to ensure fit and stability
