Product Overview
What is a Spring Cone Crusher?
The CS Efficiency Spring Cone Crusher is a time-proven compression crusher built for secondary and tertiary crushing of hard and medium-hard rock. Spring overload protection – the design that made the cone crusher the industry standard for aggregate and mining applications – automatically opens the CSS to pass uncrushable objects and resets without operator intervention, protecting the machine from tramp iron and sudden feed surges.
Six models from CS75B to CS400B cover cone diameters from 900 mm up to 2,134 mm and capacities from 45 t/h to 1,270 t/h. Each model is available in Fine, Medium, and Coarse cavity configurations to match the crushing stage and target product size. The spring cone’s simpler hydraulic-free design – fewer components, no hydraulic power unit, straightforward CSS adjustment – makes it the preferred choice for operations where maintenance simplicity and lower capital cost are the priority.

Key Features & Advantages
-
Forged 42CrMo Main Shaft - Strength, Toughness, Deep Hardenability
The main shaft is forged from 42CrMo chromium-molybdenum alloy steel. Forging produces a dense, defect-free grain structure; chromium-molybdenum alloying provides combined high strength, toughness, and hardenability for heavy eccentric crushing loads - well beyond plain carbon or low-alloy steels.
-
Copper Alloy Eccentric Sleeve Bearing - Low Friction, Extended Life
The eccentric sleeve runs on copper alloy bearings engineered for continuous high-load oscillating motion - lower running friction and superior wear resistance versus ferrous alternatives, extending bearing life and reducing heat under sustained high-duty operation.
-
Mn18 High-Manganese Liner Plates - Maximum Work-Hardening
Mantle and concave are cast from Mn18 high-manganese steel. Elevated manganese content maximizes work-hardening response: the liner surface hardens progressively in service while the core stays tough, delivering longer life than standard Mn13 on hard, abrasive feed.
-
Spring Overload Protection - Simple, Reliable, Auto-Reset
A ring of compression springs surrounds the bowl assembly and acts as a mechanical fuse. When an uncrushable object enters the chamber, the springs allow the bowl to rise, opening the CSS to pass the object. Springs reset automatically when the object clears - no manual intervention, no hydraulic system required.
-
Simple Structure - Lower Cost, Easier Maintenance
No hydraulic power unit, no PLC controller, fewer components overall. CSS adjustment is mechanical via the adjustment ring - straightforward for any maintenance team. Lower initial investment and simpler on-site servicing make the spring cone the practical choice for budget-conscious operations and remote sites with limited technical support.
-
Fine / Medium / Coarse Cavity Options - One Machine, Multiple Stages
Each CS-B model offers up to three cavity configurations covering coarse secondary crushing (large feed, wide CSS) through fine tertiary crushing (small feed, tight CSS). Cavity selection at the time of order matches the machine to its specific position in the crushing circuit.
What Is the Working Principle Of the CS Spring Cone Crusher
Feed material enters the crushing chamber between the mantle (moving cone) and the concave (fixed cone). The eccentric sleeve drives the main shaft in an oscillating motion - on each forward stroke the mantle compresses material against the concave and fractures it; on the return stroke, broken material drops through the CSS gap and exits onto the discharge conveyor.
The adjustment ring, supported by compression springs, controls the CSS by raising or lowering the concave position. To adjust CSS, the operator turns the adjustment ring via the adjustment motor or manually - opening or closing the gap as required. If an uncrushable object enters the chamber, the crushing force exceeds the spring pre-load, the bowl rises to pass the object, and springs pull the bowl back to the set position automatically.

FAQ
What is the Main Practical Advantage of a Spring Cone Over a Hydraulic Cone?
Simplicity and cost. No hydraulic power unit to maintain, no PLC to program, no hydraulic seals to replace. CSS adjustment is mechanical and can be done by any maintenance technician. Initial purchase price is lower, and on-site spare parts requirements are fewer. For medium-hard materials at operations where maintenance resources are limited, the spring cone delivers reliable performance at the lowest total cost of ownership.
How is the CSS Adjusted on a Spring Cone Crusher?
The concave is mounted on an adjustment ring that threads into the main frame. Rotating the ring clockwise closes the CSS; counterclockwise opens it. On CS-B models, the adjustment motor turns the ring on command. Manual adjustment with a spanner is also possible. The machine should be running (or stopped for a small adjustment) before locking the ring in position with the locking cylinders.
How Often do Mn18 Liners Need Replacing on Granite?
On granite (200–260 MPa), Mn18 mantles typically run 500–900 operating hours before requiring replacement, depending on CSS and feed gradation. Plan change-outs during scheduled maintenance windows. OEM Mn18 mantle and concave sets are stocked for all CS-B models – keep one spare set on site.
Can a Spring Cone Handle High Tramp Iron Content in Demolition or rRecycling Applications?
Spring cones can pass occasional tramp iron via the spring overload mechanism, but high or continuous tramp iron content (as found in C&D waste or reinforced concrete) will accelerate spring fatigue and liner wear. For recycling applications with significant metal content, a hydraulic cone with automatic CSS reset or an impact crusher with magnetic separator is the more durable solution.

Is On-site Commissioning Support Available?
Remote commissioning support via video call is included at no charge. On-site engineer dispatch is available as an optional paid service — lead time and cost depend on location. Please discuss before purchase.
