This used SC315S single-cylinder cone crusher has a 500mm feed opening and 400mm maximum feed size. Manufactured in 2018, it was previously used by a building materials company in Zhengzhou, Henan. The machine is in excellent overall condition with no major failures or structural damages. It has about 11,000 operating hours in total, operated strictly in compliance with standards without overloading, resulting in very low wear on core components.The frame is made of high-strength cast steel as a solid structure, free of cracks and deformation, with stable load-bearing capacity. The main shaft is undamaged without bending or wear, the journal is in good condition with standard fitting clearance, ensuring smooth power transmission and high coaxiality during operation. The single-cylinder hydraulic cylinder is leak‑proof and pressure‑stable, with well‑conditioned seals, sensitive and reliable hydraulic adjustment and overload protection, providing steady crushing force. The hydraulic system features unobstructed pipelines and flexible valves with stable working pressure; the lubrication system supplies oil evenly to effectively reduce wear on rotating parts. The main motor runs smoothly without ablation or aging; the electric control system has neat wiring, normal instruments and sensors, complete functions of start-stop, speed regulation and protection, with no attenuation in control performance.The machine shows only minor surface rust and paint wear, no collision damage, and can be restored neatly with simple treatment. It runs stably without vibration or abnormal noise, producing uniform particle size. The core performance remains intact. Only regular replacement of wearing parts such as concave and mantle is needed. There is no repair or replacement record of core components, and the performance is close to a new machine.With a mature single-cylinder hydraulic design, this crusher features low failure rate, long-term stable production, easy maintenance and low running cost. Its second-hand cost is much lower than a new unit while retaining full performance, no hidden troubles, low investment and fast payback, representing high cost-performance and practical value.

     This used SC315S single-cylinder cone crusher is equipped with a 500mm feed opening and a maximum feed size of 400mm. It was officially manufactured in 2018 and previously served a building materials enterprise in Zhengzhou, Henan Province. The overall condition of the equipment is at the top level among second-hand cone crushers of the same type, featuring extremely high operational integrity and operational stability, making it a rare high-quality second-hand cone crushing equipment on the market. Judging from the overall operation history of the equipment, it has a cumulative operating time of about 11,000 hours, with an average annual operating time stably controlled at around 1,600 hours. During its entire service period, it has strictly complied with standardized industrial operating procedures, and has never experienced improper use such as overloaded forced operation, frequent illegal start-stop, or brutal operation. There have been no major mechanical failures, main structural damages or core component failures during its service life. The overall service intensity is mild and controllable, and there are no hidden dangers such as excessive wear or recessive failures at all.

     Focusing on the detailed status of the core components of the equipment, the high-quality working condition of this machine can be more intuitively reflected: First, the frame part, as the load-bearing foundation of the equipment, is integrally cast with thickened high-strength cast steel, with a compact and stable overall structure. There are no visible stress cracks, weld cracks or local deformations, and the bolts at the frame connection parts are fastened without looseness. The pressure-bearing capacity has always maintained the factory standard, and can stably withstand the high-intensity impact load during crushing operations. Second, the main shaft part, as the core transmission component, has no bending deformation or obvious wear scratches on the whole body, the journal part is smooth and undamaged, the fit clearance with the shaft sleeve accurately meets the industry standard range, the coaxiality is extremely high during operation, there is no radial movement or axial offset, and the power transmission efficiency is not reduced at all. Third, the single-cylinder hydraulic cylinder part, the cylinder body has no scratches or rust, the piston seal has no serious aging, no hydraulic oil leakage or pressure relief, the functions such as hydraulic jacking, overload protection and pressure relief reset are fast and accurate, the hydraulic operation performance is fully up to standard, and can stably provide sufficient crushing force for crushing operations.

     Looking at the status of the core systems of the equipment, both the hydraulic system and the lubrication system maintain excellent working conditions: The hydraulic pipeline has no aging cracks or collision damage, there are no impurities or oil deposits inside the pipeline, each control valve opens and closes flexibly and smoothly, no internal or external leakage, the system working pressure is always stable within the standard value range, and there will be no excessive pressure fluctuation. The lubricating oil circuit is unobstructed without blockage, the distribution valve can evenly deliver lubricating oil to each operating component, no dead corners of lubrication, the oil level sensor and pressure sensor work normally, and can continuously provide sufficient and clean lubrication protection for rotating parts such as gears, bearings and main shafts, fundamentally reducing friction and wear between components. As the power core and control core of the equipment, the motor and electric control system are also in good condition: The stator and rotor of the main motor have no ablation traces, the insulation layer has no aging damage, no abnormal heating or noise during operation, and the power output is stable. The internal wiring of the electric control cabinet is neatly arranged, the wiring terminals have no looseness, oxidation or rust, all instruments display accurately, the sensor sensitivity is normal, the functions such as equipment start-stop, speed regulation, overload protection and fault alarm can be triggered accurately, the control response is sensitive, and the core control performance has no attenuation.

     The appearance of the equipment only retains normal industrial use traces, with a small amount of local paint peeling and superficial floating rust, no large-area rust penetration, collision dents, or serious mechanical scratches. There is no need to invest in large-scale renovation, and only simple derusting and paint repair can quickly restore a regular and tidy appearance. The operation status of the equipment is even more remarkable: whether it is no-load test operation or load operation, it runs smoothly and stably, the fuselage has no abnormal jitter or shaking, the operation noise meets the standards of industrial equipment, no harsh noise, the discharge particle size is uniform and stable, the impact load and operation speed during crushing operation are strictly within the design standard range, and the core crushing performance has not attenuated at all. Overall, this equipment only has normal natural wear of vulnerable parts such as concave and mantle, there is no maintenance or replacement history of core components, the overall mechanical performance is very close to that of a new machine, and it can be put into efficient production immediately after replacing the vulnerable parts.
