To clear away these confusions, we&#;ve put together a brief guide to cone crushers that explores their particular capabilities and production advantages.
The cone crusher was invented back in the s by the Symons brothers, in Milwaukee, WI. Their creation&#;called a spring cone crusher&#;soon became standard equipment for industries that require high-quality rock crushing machines. In later years, the invention of the hydraulic cone crusher provided additional options for businesses that use this type of equipment.
Today, cone crushers are commonly used in a variety of business sectors, including:
In most cases, cone crushers are used as secondary or tertiary machines in a crushing system. They process materials that have already passed through a primary crusher (which is usually a jaw or impact crusher). This ensures that the cone crushers are handling material of a manageable size.
The design of a cone crusher is fairly simple. First, the material (or feed) is dropped into the crushing cavity. Inside this cavity is the mantle, an iron or steel part that resembles an inverted cone. While in operation, the mantle gyrates in an eccentric pattern. As a result, the gap between the gyrating mantle and the concave (or bowl)&#;that is, the stationary ring around the crushing cavity&#;rapidly and continuously increases and decreases at any given point. This forceful gyration repeatedly crushes rocks against the concave.
There are two vital data points associated with the movement of the mantle: the open side setting (OSS) and the closed side setting (CSS). The OSS is the largest gap that can be created by the movement of the mantle, and the CSS is the smallest possible gap. These two settings determine the range of the sizes of the materials that are produced by the crusher.
When the machine is running, the generated crushing forces result in the gradual reduction of the size of the debris. These materials are also subject to interparticle crushing&#;that is, they are also frequently smashed against one another inside the chamber. This phenomenon aids in the efficient reduction of feed materials. Every piece of material fed into the cavity will be crushed around ten times before it leaves the machine.
Crushed objects drop lower and lower down the chamber until they become small enough to fall out of the opening at the bottom of the crusher. From there, they can be conveyed to another crushing machine, if further processing is needed. Cone crushers typically come with springs or hydraulics that enable tramp metal (such as bolts) and other uncrushable objects to pass through the chamber harmlessly.
The cone crusher is similar to the older gyratory crusher, the main difference being the design of the spindle. In a cone crusher, the spindle is shorter and supported at the bottom of the cone, rather than suspended as with a gyratory crusher.
For many types of businesses, cone crushers have long been valued pieces of equipment, due to their unique design features that provide multiple advantages over similar kinds of rock processing machines. The benefits associated with cone crushers include:
Accommodates a wide range of materials &#; Cone crushers can handle a large variety of rocks and other crushable materials, including hard and medium-hard objects. These machines are also designed to allow uncrushable objects such as tramp metals to exit the chamber without causing harm to the equipment. Only soft or viscous objects are really unsuited to the crushing process.
Adjustability &#; Cone crushers can be modified in various ways for specific production purposes. For instance, it&#;s quite common to alter the open side setting (OSS) and/or the closed side setting (CSS) in order to create products of the desired size. Many types of cone crushers also allow for the easy adjustment of mantle rotation speed, which can also play a role in the quality of the treated materials.
Few maintenance demands &#; Cone crushers have always been noted for their simplicity of design&#;there are fewer moving parts than you tend to find in similar types of machinery. As a result, there are also fewer components that are prone to wearing out, breaking down, or requiring replacement. You should, however, be sure to perform routine inspections, such as regular oil checks, to ensure that everything is working correctly.
Reliability &#; Cone crushers will serve you well for years, provided that they are given a reasonable amount of care. Over time, this durability will help to offset the initial costs of purchase.
High residence time &#; The nearly parallel angles of the concave and the mantle ensure that materials stay in the crushing chamber long enough to be properly treated. This increases the proportion of output materials that comply with your desired specifications as determined by machine settings.
High reduction ratio &#; The reduction ratio (or crushing ratio) refers to the size of the objects entering the chamber compared with their size upon exiting it. Cone crushers typically generate a reduction ratio of 4:1 to 6:1&#;and sometimes substantially higher, depending on equipment settings and other factors.
Speed &#; Not only can cone crushers smash materials into considerably smaller sizes, these machines achieve this feat in speedy fashion, which can bolster your overall production efficiency.
Low energy consumption &#; Compared with many similar types of machines, cone crushers require less energy to perform properly.
With cone crushers, the best practice is to maintain a steady choke feed, with input materials distributed into the center of the crushing chamber. This will aid the machine in outputting reasonably consistent product sizes.

The cone crusher is a widely used crushing machine in non-metallic mines, cement plants, sand and gravel metallurgy, and other industries, suitable for intermediate or fine crushing of various ores and rocks with a Proctor hardness less than 15.
Cone crushers use the gap between two inverted cones to break down ores. As the crushing force is pulsating during the operation, a spring mechanism is required. Depending on the properties of the spring, cone crushers can be divided into mechanical spring crushers and hydraulic spring crushers. Thanks to modern computer and automation technology, hydraulic cone crushers are superior to mechanical spring cone crushers in all aspects and are more popular crushing equipment.
Mechanical Spring Cone CrusherHydraulic Cone CrusherAGICO multi-cylinder hydraulic cone crusher is developed and improved by the company based on the introduction of German technology and years of our own technical experience. Our cone crusher combines perfect design of crushing speed, eccentricity, and high-performance crushing chamber. It not only has outstanding production capacity and crushing efficiency, but also expands the application range. From limestone to basalt, it can provide excellent performance in various medium crushing, fine crushing, and ultra-fine crushing operations. Its high speed and high crushing capacity characteristics ensure that the crushed materials have a high-quality cubic shape. Moreover, its easy maintenance ensures the high stability of the machine during the production operation.
Our hydraulic cone crusher features significant structural improvements over the mechanical spring cone crusher:
In addition to the improvements made to the structure of the mechanical spring cone crusher, Our hydraulic cone crusher has further optimized the performance, offering several advantages:
The hydraulic cone crusher consists of the main frame, adjustment ring, feed hopper, bowl-shaped bearing, crushing cone, mantle, bowl liner, adjusting sleeve, hydraulic control system, hydraulic cleaning chamber, and lubrication system.
The working principle of the cone crusher is to crush the ore by the squeezing and bending of the materials between the moving cone liner and the fixed cone liner. The motor drives the horizontal shaft through the V-belt and pulley, and the horizontal shaft drives the eccentric sleeve to rotate through the gear. The eccentric sleeve drives the main shaft to swing, causing the crushing cone assembly to move back and forth between the moving cone liner and the fixed cone liner, thereby crushing the ore.
The multi-cylinder hydraulic cone crusher adopts a special crushing chamber designed based on the inter-particle crushing principle, which replaces the traditional single-particle crushing principle and achieves selective crushing of materials, resulting in uniform particle size distribution. The hydraulic safety system can quickly remove the faulty material by lifting the support sleeve and the fixed cone part when the machine encounters iron or gets stuck, reducing maintenance downtime and improving production efficiency.
The hydraulic cone crusher is equipped with a TC automatic control system based on PLC and computer technology, which comprehensively detects and analyzes the relevant equipment of the crusher for control. The TC automatic control system not only has automatic control functions but also records various information, including discharge port, power, current, voltage, oil temperature, bearing temperature, feed material position, filter pressure difference, overload vibration, alarm signals, etc. Moreover, it is equipped with a communication interface, which facilitates the management staff to access and view the on-site data.
The TC automatic control system has four control loops, including the equipment operation and input power control loop, the equipment operation and feeding control loop, the lubricating oil circuit oil temperature, oil pressure, and oil cleanliness control loop, and the hydraulic discharge port adjustment and clearing the warehouse and releasing the control loop for iron blockages. Supported by these four sub-control loops, the system optimizes processing through the computer and achieves automatic control of the crusher.
The TC automatic control system is the most advanced control system that monitors the complex operating conditions of the crusher effectively with advanced intelligent control technology. It can instantly display and adjust the discharge port, motor running power, crushing force, and wear information of the lining plate and automatically compensate, keeping the discharge port running at the set value. Moreover, it can preset various operating conditions for different material properties and achieve unmanned operation to the maximum extent.
