Cone Crusher
Introduction
The Cone Crusher (NT Series) is a secondary and tertiary crushing machine designed for processing hard and medium hard materials in metallurgy, building materials, road construction, chemical, and silicate industries. Pre-crushed material is fed through the top of the cone crusher, where it is compressed and crushed between the rotating mantle and the fixed concave bowl liner.
Henan Innovative Industry manufactures Cone Crushers with processing capacity from 12 to 2200 t/h and maximum feeding size from 35 to 300 mm. Applicable materials include quartz, river pebbles, calcite, dolomite, granite, basalt, iron ore, limestone, diabase, and bluestone. Available in single cylinder and multi-cylinder hydraulic configurations to match your production requirements.

APPLICATION RANGE
STRUCTURE & WORKING PRINCIPLE OF CONE CRUSHER
The Cone Crusher operates through two cutter heads: a fixed cone (outer cone) and a movable cone (inner cone). The outer cone is fixed as part of the frame, while the movable cone sits in an eccentric bush, causing the central axes of the two cones to intersect at a bevel angle.
When the drive shaft rotates, the movable cone gyrates along the inner surface of the fixed cone. The zone where the movable cone presses against the fixed cone becomes the crushing cavity, where material is compressed, impacted, and bent until it breaks. The zone where the movable cone moves away from the fixed cone becomes the discharge opening, allowing crushed material to fall out under gravity. This continuous eccentric motion delivers efficient, uniform crushing with laminated crushing action for consistent particle size output.
TECHNICAL ADVANTAGES AND FEATURES
01.
High Capacity and Crushing Efficiency
Large production capacity and high crushing efficiency with simple structure, easy maintenance, and low running costs across continuous heavy-duty operations.
02.
Laminated Crushing for Uniform Output
Laminated crushing cavity design produces uniform-sized, cubic-shaped product with low energy consumption, reducing the need for additional reshaping stages.
03.
Multiple Cavity Types for Versatile Applications
A variety of cavity configurations are available to meet different output granularity requirements across coarse, medium, and fine crushing applications.
04.
Fully Automatic Control System
Fully automatic control ensures safe equipment operation, real-time monitoring, and automatic overload protection during continuous production.
05.
Advanced Oil Lubrication System
Durable and advanced oil lubrication system extends the service life of key components and ensures reliable long-term performance.
06.
Overload Protection System
Built-in overload protection prevents metal objects or uncrushable material from damaging the crushing chamber, protecting the equipment and reducing costly downtime.
SINGLE CYLINDER CONE CRUSHER VS MULTI-CYLINDER HYDRAULIC CONE CRUSHER
Comparison of Working Mechanism
Single-cylinder
During normal operation, the oil pump fills or drains the spindle hydraulic cylinder to move the spindle up and down and adjust the discharge port size. Best suited for soft ores and weathered materials where simpler adjustment is sufficient.
Multi-cylinder
The short, thick main shaft is supported directly by the frame, providing high bearing capacity. The eccentric sleeve drives the moving cone directly. Discharge port adjustment is achieved through a hydraulic pusher or hydraulic motor, making locking easier and more precise. Better suited for medium and high hardness materials where finer output and higher productivity are required.
Comparison of Crushing Components
Single-cylinder
Main shaft and moving cone are combined and supported by a bowl-shaped tile. The eccentric sleeve drives the main shaft to provide crushing force. Simple structure with low failure rate and low production cost.
Multi-cylinder
Adjusting the cap via hydraulic pusher or hydraulic motor drives the adjusting ring to rotate in the support sleeve, providing precise discharge port control and easy locking even under hard ore conditions.
Comparison of Maintenance
Single-cylinder
Simple and reliable mechanical structure results in a low failure rate and lower maintenance costs. The simpler the system, the higher the reliability.
Multi-cylinder
Top or side disassembly allows quick and convenient repair. Moving cone and top cone can be removed without disassembling the frame or fastening bolts, making daily part replacement faster and more practical.
