PSG Series Cone 91导航 for Sale

What is the working principle of the PSG Series Cone 91导航?

◎The PSG series cone crusher utilizes high-efficiency laminated crushing (inter-particle crushing) technology, driven by an electric motor that rotates the eccentric sleeve via a durable V-belt drive and coupling. This rotation forces the main shaft and crushing cone (mantle) to gyrate in a continuous oscillatory motion, periodically moving closer to and farther from the stationary bowl liner (concave).

Laminated Compression & Particle Sizing: When the mantle gyrates toward the concave, the crushing gap narrows. The incoming feed material undergoes high-force compression, bending, and shear. Through advanced inter-particle laminated crushing, material is crushed not only by the liner surfaces but also by intense pressure between the ore particles themselves, significantly maximizing crushing efficiency and yielding cubical, uniform product shapes.
Continuous Gravity Discharge: As the crushing cone moves away from the fixed cone, the crushing chamber opens up. Ore particles that have reached the target size discharge freely downward under gravity. This continuous cycle of gyratory compression and discharge repeats seamlessly, completing one full crushing cycle with each oscillation.
Hydraulic Discharge Setting & Overload Protection: The PSG cone crusher features an integrated hydraulic system for precise, real-time discharge opening adjustment, allowing operators to tightly control final output particle size.
Spring Tramp Release & Cavity Clearing: Equipped with a heavy-duty mechanical spring safety system, the crusher automatically lifts the bowl assembly when tramp iron or uncrushable objects enter the cavity, allowing foreign material to pass safely before resetting immediately. Complementing this, an auxiliary hydraulic cavity clearing system rapidly clears stalled material or blockages, minimizing operational downtime and ensuring non-stop performance in secondary and tertiary mining circuits.

Common Problems

This section is designed to address the most pressing inquiries customers may have regarding the daily operation, maintenance, product advantages, and after-sales service of our machine. Our aim is to help you gain a comprehensive understanding of our overall capabilities and enable you to make informed decisions for your projects.

The PSG series cone crusher is designed for crushing various hard and medium-hard materials with compressive strengths up to 350 MPa, including granite, basalt, iron ore, limestone, quartzite, marble, copper ore, and river pebbles. It is widely used in mining, metallurgy, construction, and aggregate production industries.

Based on the lamination crushing principle, the PSG series cone crusher provides superior product quality with a high percentage of cubic-shaped particles and fewer flaky particles. The PSG series cone crusher features a robust structural design with a large-diameter main shaft and heavy-duty frame, ensuring high stability and reliability. Equipped with an independent forced lubrication system and tramp iron protection device, it minimizes downtime and reduces operating costs. All components of the PSG series cone crusher can be accessed from the top or side for easy maintenance.

The capacity of the PSG series cone crusher varies depending on the model, cavity type (coarse, medium, fine), and feed conditions, typically ranging from 45 tons/hour to 700 tons/hour.

The PSG series cone crusher adjusts the discharge opening by rotating the adjustment ring using a hydraulic system, thereby raising or lowering the fixed cone. After adjustment, the adjustment ring is locked with nuts and lock washers to prevent loosening due to vibration during operation.

1. Monitor oil level, oil quality, and oil temperature: Maintain the oil level within the specified range, keep the oil clean (lubricating oil NAS grade ≤ 8), and control the oil temperature between 35-55℃ (stop the machine immediately if the temperature exceeds 70℃). 2. Ensure sufficient air pressure in the positive pressure air system (0.02-0.05 MPa) to prevent dust contamination. 3. Use appropriate lubricants, such as ISO VG46/68 lubricating oil for the lubrication system and molybdenum disulfide lithium-based grease for the bearings. 4. Regularly check the oil pump, filter, and hoses for leaks or blockages, and replace aging hoses every 1-2 years.

The liners should be replaced when the crushing wall and concave liner wear exceeds 30% of their original thickness or when cracks appear. Before replacement, clean the burrs on the cone surface, remove rust from the new liners, and tighten the bolts to the specified torque. After installation, recalibrate the discharge opening gap to ensure crushing efficiency. The service life varies depending on the material hardness and feed rate, usually 3 to 12 months.

Common reasons include uneven wear of the liners (especially at the lower crushing wall and feed opening), loose discharge opening adjustment, or oversized feed particle size (exceeding equipment limits). Solution: Replace severely worn liners, recalibrate the gap and relock the adjustment ring, and install a pre-screening device to control the feed particle size within 80% of the maximum allowable feed size

1. Immediately stop the machine, use a hydraulic lifting device to lift the main shaft, and manually remove foreign objects (such as iron blocks) from the crushing chamber (do not force start). 2. Disassemble the main shaft bushing, remove the deteriorated grease, and refill with high-temperature extreme-pressure grease, ensuring that the lubrication channels are unobstructed. 3. Check the safety spring assembly, replace damaged or failed springs, and adjust the compression amount to 20-30mm (as specified).

Product Inquiry

PSG Series Cone Crusher

The PSG series cone crusher is widely used in metallurgy, construction, road building, chemical industry, and silicate industry. It is designed to crush hard and medium-hard ores and rocks such as iron ore, copper ore, limestone, quartz, granite, and sandstone. In a crushing line, the PSG series is typically placed after a primary 91导航 crusher or gyratory crusher to perform secondary and tertiary crushing stages.One key improvement of the PSG series over the PY series is the redesigned distribution plate. This allows the PSG series to achieve full-chamber feeding, resulting in higher output and better particle shape compared to the PY series.The PSG series is available in two cavity types: Standard and Short Head. The Standard type accepts larger feed sizes and produces coarser output, making it suitable for secondary crushing. The Short Head type accepts smaller feed sizes and produces finer output, making it ideal for tertiary and fine crushing applications. In general, the Standard type is used for coarse and medium crushing, while the Short Head type is used for medium and fine crushing.
