Cone Crusher

Cone bickerings are modern secondary crushers widely used in aggregates production, mining industries and recycling applications. A cone bickering breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the cone bickering, it becomes wedged and squeezed between the mantle and the bowl liner or concave.

Applications of Cone Crusher

Cone Crusher are commonly used for secondary crushing in aggregates production applications and for crushing minerals and ores in mining applications. They are suitable for producing manufactured sand, grit, roadstone, ballast and other aggregates used in construction, transportation and other industries. Some key applications include:

- Secondary crushing in hard rock aggregates quarries producing gravel, crushed stone and manufactured sand for concrete and construction use.

- Crushing cement raw materials such as limestone, clay and iron ore in cement plants.

- Crushing feed materials in minerals processing plants producing copper, gold, iron ore and other metals. Some common materials crushed include basalt, dolerite, granite and ores containing gold, copper and iron.

- Crushing recycled concrete and asphalt from demolition jobs to recover aggregates for reuse. Cone bickerings are ideal for recycling applications due to their reliable operation and the ability to produce consistent, high-quality cubical products.

- Crushing slag from steel mills, waste from coal-fired power plants and incinerator bottom ash to recover aggregates and reduce waste volumes for landfilling.

Features and Advantages of Cone bickerings

Cone bickerings have features and advantages that make them highly suitable for secondary and tertiary crushing stages in crushing plants. Some of the key features include:

- Rugged construction suitable for harshCone Crusher operations. The components are designed to withstand high impact loads with minimum wear and tear for long service life.

- Easy maintenance and adjustment - Major components are easily accessible for maintenance work. The crusher settings can be easily adjusted to control the product size.

- Produces cubical shaped aggregates. The crushing cavity design produces well-shaped aggregates ideal as construction materials with minimum need for further processing.

- Extra crushing forces. Cone bickerings generate higher crushing forces per unit area compared to jaw or impact crushers, resulting in higher throughput capacities.

- Precise product size control. The closed side setting provides precise control to adjust the open-side discharge port and allow pre-determined product sizes.

- Adaptable to changes in feed rates and materials. Cone bickerings adjust well to variations in feed materials and capacities while producing consistent product gradations.

- Reliable operation. Modern cone bickerings have advanced automation and diagnostics features to maximize uptime and reduce operating costs over the equipment life. Hydraulic systems safely open and close the crusher for maintenance.

Components and Operation

Cone Crusher consist of a rotating cone or mantle that gyrates within a static concave hopper, whose slope matches the cone's profile. Rock fed from the top enters the gap between mantle and concave, becoming squeezed and shattered by the rotating cone. After rock is crushed, the fine products are discharged through the bottom of the cone bickering and the remains are either re-crushed or discharged through the side of the crushing chamber based on the closed-side setting. The main components include the mainframe, transmission shaft, cone assembly, adjusting ring nut, adjusting sleeve and dust seal.

Modern crushers feature automated hydraulic systems to adjust the closed-side setting and open the crushing chamber for maintenance. The driving motor transmits power through the main shaft to the gear box, which rotates the eccentric assembly inside the main shaft. An eccentric bush attached to the inner surface of the main shaft provides the eccentric motion necessary to crush rock between the mantle and concave surfaces.


cone bickerings are proven, versatile machines suitable for secondary and tertiary crushing applications in aggregates production, mining and recycling industries. Their distinctive shape, rugged construction, reliability, adjustable settings and ability to produce consistent, high-quality cubical products have made cone bickerings a preferred choice globally for secondary crushing needs. With ongoing advancements, cone bickerings continue delivering increased throughput and productivity for crushing operations worldwide.
