Based on the traditional multi-cylinder hydraulic cone crusher design—with a fixed main shaft, eccentric sleeve rotating around the main shaft, and lamination crushing principle—the HPT series multi-cylinder hydraulic cone crusher has undergone groundbreaking structural optimization, significantly improving the equipment's performance and crushing capacity. Additionally, the supporting hydraulic lubrication system ensures the equipment operates more intelligently and reliably. This series of equipment uses an advanced PLC electrical system, which continuously monitors the crusher and provides alerts, displaying operating parameters so operators can understand the crusher's status in real-time, thereby simplifying production line operations, reducing operational risks, and enhancing the safety of the crushing production line. The HPT series has a processing capacity of 45-1200 t/h, a maximum installed power of 630 kW, and a feed size of 0-350 mm. It covers six models: HPT100, HPT200, HPT300, HPT400, HPT500, and HPT800. Each model is equipped with five cavity configurations—C1 Extra Coarse, C2 Coarse, M Medium, F1 Fine, and F2 Extra Fine—to meet the needs of medium crushing, fine crushing, and ultra-fine crushing operations. Why choose the HPT series multi-cylinder hydraulic cone crusher? 1. Higher capacity: Utilizing a unique working principle and optimized structural design, it offers higher load-bearing capacity, greater installed power, and improved output. 2. Better final product shape: Using the lamination crushing principle, the final product is cubic with a high fine fraction, meeting the requirements for high-quality sand and gravel aggregates. 3. Versatile operation: By simply replacing the corresponding cavity liners and other components, the crusher can switch between cavity types to meet different medium and fine crushing process requirements. 4. Fully hydraulic control: Accurate and reliable, the discharge port size can be remotely adjusted continuously and precisely via the forward and reverse rotation of the hydraulic motor. 5. PLC integrated control: Easier operation and safer production. 6. Hydraulic protection and automatic cavity clearing: Equipped with a bidirectional hydraulic safety cylinder, it has a sensitive iron protection function, reducing downtime for maintenance. The HPT series multi-cylinder hydraulic cone crushers are mainly used in the metal mining industry. They are used for medium and fine crushing of ores in gold, copper, iron, and other metal mining operations, providing high-quality raw materials for subsequent beneficiation processes such as ball milling, flotation, and magnetic separation. Construction aggregate production can process materials such as limestone, river pebbles, and basalt into construction aggregates that meet different specifications, widely used in concrete batching plants, dry mortar production, and other fields; the cement and metallurgical industries can perform medium and fine crushing of raw materials such as limestone and clay, and crush and process iron ore, manganese ore, and so on; gravel quarries, railway and highway construction, water conservancy projects, and other projects. The people who need the HPT series include metal mining enterprises, gravel yards and aggregate producers, equipment purchasing departments of cement and building material enterprises, equipment maintenance departments of metallurgical and chemical enterprises, EPC contractors of crushing and screening production lines, equipment dealers and stockists, and procurement parties of overseas mining and building material projects. Under what circumstances should you choose or replace the HPT series cone crusher? When medium and fine crushing of high-hardness ores and rocks such as granite, basalt, iron ore, etc., is required; when high product particle shape is required, with a high proportion of cubic shape and few flaky particles; when you want to increase output and replace traditional spring cone crushers or old cone crushers; when multi-functionality is needed, with conversion between medium and fine crushing achievable by changing the chamber liner; when the old cone crusher is severely worn, has insufficient capacity, or the finished particle shape does not meet standards; when a new sand and aggregate production line or mine crushing line requires medium and fine crushing equipment. How to choose an HPT series multi-cylinder hydraulic cone crusher? Step one: Confirm material hardness and feed size. The HPT series is suitable for a feed size of 0-350mm and can handle various ores with compressive strength not exceeding 300MPa. Step two: Confirm the crushing stage, choosing medium crushing (C1/C2/M chamber type) or fine/ultra-fine crushing (F1/F2 chamber type). Step three: Confirm the maximum feeding size and select the corresponding chamber feed opening size according to the material particle size. Step four: Confirm processing capacity and select a model within the 45-1200t/h range according to production line capacity requirements. Step five: Confirm motor power and choose a motor from 90-630kW based on processing capacity. Step six: Confirm chamber conversion requirements; simply replace the corresponding chamber liner and other components to achieve the chamber conversion. Step seven: Confirm the installation foundation, as the cone crusher needs to be installed on a solid concrete foundation, secured with anchor bolts; Step eight: Confirm the hydraulic and lubrication system configuration. The full hydraulic control system and PLC integrated control system ensure overload protection and intelligent operation.

Installation method: HPT series multi-cylinder hydraulic cone crushers need to be installed on a solid concrete foundation, which should withstand the equipment’s own weight and the huge impact load during crushing operations. During installation, ensure the foundation level meets requirements, and tighten anchor bolts according to torque specifications. After positioning the equipment, adjust the level to ensure the main shaft is parallel to the motor shaft. The motor and crusher are connected via V-belt or direct drive; belt tension or alignment accuracy needs adjustment to ensure smooth transmission. The hydraulic system should be properly connected, and overload protection, iron-block protection, and discharge port adjustment functions should be debugged. The lubrication system must be correctly connected to ensure proper bearing lubrication. The PLC control system must be correctly wired and debugged for online monitoring and fault alarm functions. After installation, perform a no-load trial run to check whether the main shaft rotates smoothly without abnormal vibration or noise and confirm the gap between the crushing wall and mantle is even. During load trial runs, gradually increase the feed, observe crushing performance and motor current, and ensure it does not exceed the rated current. A dust removal system must be equipped to reduce dust pollution.

Selection considerations (compared with the HST series single-cylinder hydraulic cone crusher): The core differences between the HPT series multicylinder hydraulic cone crusher and the HST series single-cylinder hydraulic cone crusher arestructural principle, hydraulic system configuration, and applicable scenariosThe HPT series adopts a spindle-fixed, eccentric sleeve rotating around the spindle structure and the laminated crushing principle. It is equipped with a PLC integrated control system and a fully hydraulic operating system. The bidirectional hydraulic safety cylinder has a sensitive iron-overload protection function. It has a processing capacity of 45-1200 t/h, covering a full range from coarse, medium, fine, to ultra-fine crushing. The HST series uses a spindle supported at both the top and bottom ends, capable of withstanding greater crushing force and larger stroke, with high crushing efficiency. Its output is 35%-60% higher than that of the old spring cone crusher, and the proportion of cubical finished products is high. When selecting, projects with high requirements for intelligent control, iron-overload protection, and multi-functionality should preferentially choose the HPT series, while projects requiring high crushing force and stroke and pursuing high capacity should preferentially choose the HST series. Both are suitable for medium and fine crushing operations in metal mines, sand and gravel aggregates, and the cement industry.
