What are cone crushers?
Cone crushers are used to take hard rock and other tough materials that have already been crushed once and reduce them even further.They are most often used after a jaw crusher or another primary crusher has done the first stage of the work.
A cone crusher uses compression to break the material down. Think of it as a moving cone inside a fixed bowl. The rock gets caught between the two surfaces and squeezed until it breaks.
Cone crushers are commonly used in aggregate production because they can produce a smaller, more consistent and more evenly shaped finished product.
Depending on the application and crusher setup, they can also achieve fairly high reduction ratios. A 4:1 reduction ratio, for example, means material can be reduced to roughly one-quarter of its original size.
How cone crushers work.
Crushing chamber
Inside the crushing chamber of cone crushers is two main crushing surfaces: a stationary outer liner called the concave and a moving inner liner called the mantle.
The mantle is continuously moving in a slightly off-centre (elliptical) motion. As it moves, the space between the mantle and concave constantly opens and closes. The changing gap is what does the crushing. When the gap gets smaller, the material is squeezed between the two surfaces with enough force to fracture and break. As the mantle moves away again, the broken material drops further down into the crushing chamber where it is then caught and crushed again.
The process continues until all of the material has passed through the bottom of the crusher.

Open and Closed Side Settings
The smallest distance between the the mantle and concave is called the closed side setting (CSS). CSS is one of the main adjustments used to control the size of the finished product. A smaller CSS produces finer material. A larger setting allows larger material to pass through the crusher.
The widest distance between the mantle and concave is called open side setting, or OSS.
Maxtrak Cone Crushers – Designed for Mobility and Maximum Productivity.
The Maxtrak range of cone crushers from Powerscreen have been designed and engineered with an eye on maximum productivity, which is the cornerstone of the highly successful Powerscreen philosophy.
Powerscreen Maxtrak cone crushers are suitable for crushing a wide range of materials, medium to fine crushing ratios and continuous feed grinding. The machine offers the most flexible design of any cone crusher, meaning it can be used as a secondary or tertiary crusher in a wide range of aggregate and recycling applications.
Automax Cone Crusher – The Heart of Maxtrak
The heart of the Maxtrak crushing plant is the Automax® cone crusher with hydraulic setting, Tramp Iron Release, and (2) Unblocking System. Its unique crushing action provides excellent capacity, high reduction, and good product cubicity to produce high-quality aggregate and sub-base materials.
Tramp Iron Release is a safety feature.
Tramp iron refers to any unwanted metal piece, like a bolt or a piece of steel, that accidentally gets mixed with the material being crushed. These pieces can cause damage to the crusher. The tramp iron release feature allows the crusher to adjust automatically to let this unwanted metal pass through without causing damage. Think of it like a safety valve that opens up when something too hard to crush comes along.
Unblocking
Sometimes, the material in the crushing chamber can get stuck or block the crusher, stopping it from working correctly. The unblocking feature helps quickly clear these blockages without manually removing the stuck material, which keeps the crusher running smoothly and reduces downtime.
