Cone crusher is one of the widely used mining machinery and equipment. With the development of the market, there are many types of cone crushers at home and abroad which have various performances. Therefore, how to correctly select the models has become one of the most concerned issues for users. And at the following introduction, we will take the three mainstream cone crushers on the market as examples to help users choose the most suitable machine by analyzing their structural characteristics, advantages and disadvantages.
Symons cone crusher
Symons cone crusher is the earliest cone crusher, as well as the most widely used crusher in the world. Based on the introduction and absorption of foreign technology and according to the customer's needs, it has been developed into a modern and high-performance cone crusher integrated with high swing frequency, optimized cavity and reasonable stroke by adopting the principle of laminating crushing and the concept of more crushing and less grinding. After the optimization and improvement of the experts, Symons cone crusher has a more reasonable structure and advanced technology, and performs excellently in manufacturing, installation, use and maintenance.
Applicable and non-applicable areas
It can be widely used in metal and non-metal mines, cement plants, building construction, sand making and metallurgy, etc. It is also suitable for iron ore, non-ferrous metal ore, granite, limestone, quartzite, sandstone, pebbles, etc.
However, since the Symons cone crusher crushes by reducing the size of the discharge port to control the particle size of the product, the machine is not suitable for use as ultrafine crusher or sand making.
It has the following advantages
Many types of crushing chambers: According to the site conditions, the user can choose three different chambers which have high crushing efficiency, uniform product size, well-shaped granule, uniformly worn concave and wear parts with long service life.
Dry oil seal for dustproof: It adopts a unique dustproof sealing structure which is reliable, effectively prolonging the replacement cycle of lubricating oil and the service life of parts.
Support for large crushing ratios: Key parts are manufactured by special material. The space when the crushing cone leaves the concave is large in each stroke, allowing more material to enter the crushing chamber and forming a larger discharge volume, which speeds up the passage of the material through the crushing chamber.
High output: Compared with other models, Symons cone crusher has a long broken arm with large stroke and crushing force. So it can crush much more materials in the crushing chamber effectively.
High efficiency: The main shaft of the machine has support at both upper and lower ends, which can withstand greater crushing force and larger stroke. In addition, it has a special crushing cavity shape suitable for the lamination principle, which makes the machine have higher crushing efficiency.
Low maintenance cost for daily operation: Because of reasonable part selection and structural design, long service life of parts and long crushing arm length, load on sliding bearings, gears and frames have been reduced greatly; uniform particle size of crushed products reduces cyclic load; hydraulic clearing system is easy to operate and control, reducing downtime and power consumption.
Discharge port adjustment: Symons cone crusher includes a hydraulic adjustment mechanism to quickly adjust the size of the discharge port.
Lubrication circulation system: Special light oil lubrication circulation system ensures that the oil return temperature is within60℃; the new oil filtration system ensures that the transmission device is not accidentally worn, thus stabilizing the service life. This advanced and reliable double pump oil supply lubrication system ensures the temperature rise of the main shaft and copper tile, long service life, reliable operation and extended maintenance period.
Overload protection: The spring safety system is an overload protection device that allows metal objects to pass through the crushing chamber without damaging the machine.
Single cylinder hydraulic cone crusher
The single-cylinder hydraulic cone crusher is developed with the world's advanced crushing technology, integrating mechanical, hydraulic, electrical and intelligent technologies. The new crushing structure, optimized laminated crushing chamber and fully automatic control system make the single-cylinder hydraulic cone crusher special with the performance characteristics that traditional cone crusher does not have.
Applicable and non-applicable areas
It is widely used in metallurgy, construction, cement, water conservancy, highways, railways, mineral processing and other fields, with medium, fine, ultra-fine crushing functions.
However, the crushing force of the single-cylinder hydraulic cone is slightly insufficient, especially for crushing hard materials. Because the adjustment method is to lift and lower movable cone, the wear and tear of concave is not uniform under the condition of uneven feeding. Besides, the oil cylinder is at the bottom, leaving small space for lower parts, which brings certain difficulties to maintain.
It has the following advantages
More uniform grain size: The single-cylinder hydraulic cone crusher adopts the unique crushing cavity shape and laminating crushing principle, so that the proportion of cubes in the finished product is obviously increased, the needle-like stones are reduced, and the grain size is more uniform;
Large production capacity: The high swing frequency and large inclination of steep slope design make the throughput of the single-cylinder hydraulic cone crusher 40% larger than the ordinary cone. In addition, the feed port of the machine is also larger than the ordinary cone. So it will be destined to have a higher production capacity than the general ones;
High degree of automation: Compared with the old version of the spring cone crusher, the new single-cylinder hydraulic cone crusher can automatically adjust the size of the discharge port without stopping the machine, and can also be equipped with a computer control system for remote operation;
Good energy-saving and environmental protection: Under the same production capacity, the single-cylinder hydraulic cone crusher consumes less energy per unit hour.
Multi-cylinder hydraulic cone crusher
The multi-cylinder hydraulic cone crusher is suitable for crushing various ores and rocks of medium and or above hardness, such as limestone, iron ore, pebbles, non-ferrous metal ore, granite, basalt, limestone, quartzite and sandstone.
Its high speed, high crushing capacity and unique patented design make the finished product with an extremely high-quality cube shape, and the easy maintenance features ensure extraordinary high stability operation. It is a new generation of products that replaces spring cone crushers and newer general hydraulic cone crushers.
Main strengths and weaknesses
Its high speed, high crushing capacity and unique patented design make the finished product with an extremely high-quality cube shape, and the easy maintenance features ensure extraordinary high stability operation. It is a new generation of products that replaces spring cone crushers and newer general hydraulic cone crushers.
However, since the multi-cylinder cone crusher has small a R radius of the spherical surface, so the radius of the swing is small, causing unstable phenomena such as swaying, tipping, and flying of the moving cone, as well as problems such as poor contact between the main shaft and the bushing, and large impact force, which affects the normal work of the machine. But its processing capacity is higher, and the material smaller than the discharge port can even account for 70%~80% of the total volume.
It has the following advantages
Hydraulic motor adjusts the discharge port: The whole hydraulic operation is adopted from the insurance clearing chamber to the adjustment and locking, and hydraulic lubrication combined oil station is small in size and simple to wire.
Fixed shaft structure design: It adopts a unique structure that the main shaft is fixed and the eccentric sleeve rotates around the main shaft. Optimized transmission components and internal structure design make it strong in bearing capacity with advantages of large installed power, small size, high efficiency and low noise.
Laminated crushing chamber design: The material is crushed by the principle of laminating crushing, and the crushing efficiency is greatly improved by optimizing the equipment and cavity type; the finished material has a cubic shape, uniform fineness with high quality.
PLC+ touch screen automatic control system: The operation is more stable and reliable, easier to operate. The downtime is reduced greatly, achieving completely automatic operation.
Various crushing chamber configuration: When equipped with the medium and fine crushing chamber, only a small number of parts such as the corresponding cavity liner are needed to replace, meeting the needs of medium and fine crushing process and achieving a versatile use of the machine.
