The HPT Hydraulic Cone Crusher is a high-efficiency medium-fine crushing equipment utilizing the laminar crushing principle, specifically designed for secondary/tertiary crushing operations in metal mining, construction aggregates, and similar industries. Its core structure comprises a fixed cone assembly, a moving cone assembly, multiple hydraulic cylinders, and an intelligent control system. Through a unique design featuring a fixed main shaft and rotating eccentric sleeve, it achieves continuous compression and laminar crushing of materials within the crushing chamber. This equipment achieves a maximum processing capacity of 1200 tons per hour, handling medium-hard materials like iron ore and granite. In iron ore fine crushing projects, its output reaches 1.9 times that of traditional equipment. Its modular design incorporates 10-16 integrated hydraulic cylinders, featuring both iron overload protection and automatic discharge opening adjustment. Equipped with a Siemens PLC control system, it enables fully automated operation and real-time monitoring. As a technological upgrade to spring cone crushers, the HPT series significantly enhances crushing efficiency and product quality by optimizing the moving cone trajectory and crushing chamber configuration. The HPT hydraulic cone crusher operates on the principle of laminar crushing, centered on the rotating swing motion of the moving cone driven by an eccentric sleeve. The motor drives the eccentric sleeve via a transmission shaft, forcing the moving cone to swing along the crushing chamber wall. Material undergoes multidirectional compression, bending, and shearing between the moving and fixed cones. This unique laminated crushing design shifts the primary crushing action between particles rather than direct liner contact, reducing energy consumption and over-crushing. The hydraulic system achieves three functions through multiple cylinders: dynamic adjustment of the discharge opening size (with ±1mm precision), iron overload protection (with adjustable pressure thresholds), and automatic crushing chamber cleaning. When non-crushable objects enter the chamber, the hydraulic system triggers pressure relief protection. The movable cone instantly descends to widen the discharge opening for ejecting foreign objects, then automatically resets. The intelligent control system continuously monitors main shaft speed, oil pressure, and vibration data. Through PLC algorithms, it optimizes the matching of eccentricity and swing frequency, boosting crushing efficiency by over 30%. This synergy of mechanical, hydraulic, and electrical systems enables the equipment to maintain a wide processing capacity range of 45-1200 tons/hour while reducing energy consumption by 43% compared to traditional models. The technical advantages of the HPT hydraulic cone crusher manifest in three dimensions: First, its multi-cylinder hydraulic system synergizes with the laminating crushing chamber to elevate the cubic content of finished aggregates to over 90% while reducing needle- and flake-shaped particles by 50%, significantly enhancing concrete aggregate quality. Second, the intelligent control system, powered by Siemens PLC, enables automatic discharge opening adjustment (±0.5mm precision) and overload protection. Combined with ABB low-voltage components, it reduces failure rates by 60% and extends maintenance intervals to 2000 hours. Finally, the modular design permits side-access replacement of the moving cone assembly. A triple-path lubrication system ensures stable operation of critical components like the eccentric sleeve and spherical bearings across temperatures from -30°C to 50°C, extending the machine's service life by 40% compared to conventional models. This equipment holds ISO9001 certification. Its eco-friendly mining characteristics have been validated in projects like Hubei pebble sand production, achieving a capacity of 200 tons/hour with dust emissions below 10mg/m³.

In terms of high-efficiency laminar crushing technology

The HPT hydraulic cone crusher achieves multi-angle continuous compression of materials within the crushing chamber through the coordinated design of a fixed main shaft and rotating eccentric sleeve. Its optimized eccentricity combined with motion parameters increases the compression stroke at the upper part of the moving cone, providing ample crushing pressure to the middle and lower sections of the chamber while preventing over-crushing of materials. This technology is particularly suited for high-hardness materials like iron ore and granite. In the Baotou magnetite project in Inner Mongolia, the HPT model served as the core equipment in the fine crushing stage, successfully reducing material to below 13mm. This significantly reduced energy consumption in subsequent grinding processes. The layer compression crushing principle enhances efficiency through mutual material compression, reducing needle and flake content in finished aggregates by 20%-30% while significantly increasing cubic particle proportions. This meets stringent aggregate shape requirements for high-grade concrete. Furthermore, by minimizing direct impact between metal components and materials, combined with a high-manganese steel crushing wall design, this technology enables the equipment to achieve outstanding performance—continuous operation for 8,000 hours without major repairs—in projects such as the Luanping Iron Ore Mine in Hebei Province.

Intelligent Hydraulic System

The HPT hydraulic cone crusher achieves precise production control through multi-cylinder hydraulic coordination technology. Its hydraulic system incorporates a triple mechanism of relief cylinders, locking cylinders, and thrust cylinders. This not only enables automatic pressure release during iron overload events but also allows millimeter-level discharge opening adjustment via hydraulic motor-driven fixed cone rotation. This technology is deeply integrated with the Siemens PLC control system, enabling real-time monitoring of critical parameters such as crushing chamber pressure and main shaft speed. It automatically adjusts the eccentric sleeve stroke to match different material characteristics, controlling product particle size fluctuations within ±0.5mm at the Dandong Gold Mine project in Liaoning. The hydraulic cavity-clearing system eliminates the need for shutdowns during material discharge, a common pain point in traditional equipment. Upon encountering non-crushable materials, the system completes pressure release and fault clearance within 3 seconds, achieving over 90% efficiency improvement compared to manual intervention. Additionally, the hydraulic lubrication system employs a labyrinth seal design, completely eliminating bearing wear caused by oil-water mixing. Combined with circulating oil cooling technology, it achieves zero lubrication system failures during continuous operations like granite processing in Macheng, Hubei. The system's intelligent diagnostics also use vibration sensors to provide early warnings of bearing abnormalities, boosting preventive maintenance efficiency by 40% and significantly reducing unplanned downtime risks.

Energy Efficiency and Environmental Design

The HPT hydraulic cone crusher achieves dual optimization of energy consumption and emissions through innovative technology. Its hydraulic system replaces traditional spring structures, boosting power transmission efficiency by 15%-20%. At the Luanping Iron Ore Project in Hebei, unit energy consumption dropped to 0.609 kW·h/t—a 43% reduction compared to conventional equipment. The optimized crushing chamber design, combined with the layer compression principle, forms a dense material layer within the chamber. This reduces ineffective crushing energy consumption while lowering dust generation by 60%. The equipment features a fully enclosed dust-proof design, with labyrinth seals at critical joints and negative pressure dust extraction interfaces.

This design aligns with green mining construction requirements, assisting clients in passing environmental inspections at projects like the Baotou magnetite mine in Inner Mongolia while lowering operational costs.

Fully Hydraulic Control HPT100 Cone Crusher: Stable, Reliable, and Hassle-Free! Works Principle

The HPT hydraulic cone crusher employs the laminar crushing principle, achieving efficient and precise material crushing through a multi-cylinder hydraulic system. Its core operating mechanism can be divided into the following three key stages:
The motor drives the transmission shaft via a pulley or coupling, causing the eccentric sleeve to rotate. The rotational motion of the eccentric sleeve is transmitted through the main shaft to the moving cone, causing it to perform a swinging motion around a fixed point.
This design causes the gap between the crushing wall and the bowl liner to periodically change, creating a continuous squeezing action on the material. The bottom of the moving cone is supported by a single hydraulic piston, which not only bears the crushing load but also replaces the traditional spring relief device, simplifying the structure. After entering the crushing chamber, the material is subjected to multi-directional forces due to the swinging motion of the moving cone. Based on the layer compression theory, a stable material layer forms within the crushing chamber. Efficient crushing is achieved through the “material crushing material” layer compression effect. This crushing method produces more uniform final particle shapes, significantly increases the cubic content, and reduces needle and flake particles by 20%-30%. When the material meets discharge requirements, it falls through the gap created by the swinging crushing walls. Material that does not meet specifications continues to be crushed.
The multi-cylinder hydraulic system automatically adjusts the discharge opening via 10-16 hydraulic cylinders. When the oil pump supplies hydraulic fluid to the cylinders, the moving cone rises to reduce the discharge opening. When oil is released, the movable cone descends, enlarging the discharge opening. Should uncrushable foreign objects enter the crushing chamber, the hydraulic system automatically triggers protection: the accumulator piston compresses nitrogen, hydraulic oil enters the accumulator, and the movable cone descends to widen the discharge opening for foreign object ejection. After ejection, the hydraulic system automatically resets the movable cone to restore the original discharge opening position.
The equipment features a Siemens PLC and touchscreen system for real-time monitoring of parameters such as spindle speed and hydraulic pressure. Displacement sensors enable precise control of the discharge opening size with millimeter-level adjustment accuracy. The hydraulic lubrication system employs a labyrinth seal structure to effectively prevent dust contamination and extend the service life of critical components.
