The above crushing chamber can also be made for coarse crushing (ГP, ГP2 type) and for ultrafine crushing (T, T1, T2, T3... type) crushing equipment. Its structure is shown in Fig. 20. Its remote control, automatic lubrication system and associated supply equipment are basically the same as the company's rotary crusher. Model meaning example KMД-3000T2-ДП: KMД——fine crusher cone crusher, 3000——breaking cone diameter (mm), T2——breaking chamber is T2 type, Д——with remote controller, П——with feed Dispenser. [next] (2) Spring overload protection. Spring overload protection does not require any actual maintenance to reliably protect the crusher. The spring safety system consists of several sets of coil springs that press the support ring and the adjustment ring onto the frame. When a small unbroken object falls into the crusher, the adjustment ring rises due to the supplemental compression of the compensated crushing cone stroke spring. As the discharge opening returns to its original size, the adjustment ring automatically returns to its original position. The unbroken material is passed through the crusher after being squeezed two or three times. (4) Discharge port hydraulic adjustment system. The system eliminates the heavy manual handling during maintenance and guarantees the stability of the quality of the broken product. The size of the discharge opening can be adjusted by means of the adjusting ring swivel mechanism. Pre-press the coil spring on the flange of the threaded ring, first pull the adjusting ring out for axial fixing. Before adjusting the discharge opening, remove the fixing force with a hydraulic cylinder supplemented with a compression spring. A hydraulic cylinder with a push rod fixed to the rotating column is used as the swing mechanism. The discharge port size adjustment system (Fig. 23) can be operated in fully automatic and manual control systems to sequentially complete all movements of a single cycle (rotating the sheath one tooth) or each action.

The PYH series hydraulic high-efficiency cone crusher developed and produced by the company has the superiority of the over-spring cone crusher and the general hydraulic cone crusher. Its characteristics are as follows:
(1) The machine adopts the unique patented design of “eccentric bushing around the fixed axis rotationâ€, which strengthens the strength of the main shaft and creates conditions for achieving high power crushing. At the same time, through the use of the special crushing chamber designed by the principle of intergranular lamination and the matching speed, the crushing ratio and the output are significantly improved, and the content of the cube of the finished material is increased.
(2) In the case of iron and instantaneous smoldering, the machine can hydraulically lift the top and automatically discharge the material, which greatly reduces the trouble that the original spring cone crusher needs to stop for manual discharging, making maintenance easier and more expensive. saving.
(3) Hydraulic adjustment, thin oil lubrication, and effective labyrinth sealing method, fundamentally eliminate common faults such as oil-water mixing of the original spring cone crusher.

The technical parameters of PYH hydraulic high efficiency cone crusher are shown in Table 25. The external dimensions are shown in Figure 9.
(1) S series spring cone crusher. The spring cone crusher is the world's first cone crusher. After nearly a hundred years of continuous improvement, its machine structure design is reasonable, the crushing principle and technical parameters are advanced, and the operation is reliable. The S series spring cone crusher features high efficiency, high output and low operating cost.
1) High efficiency. According to the advanced crushing principle, the crushing chamber and the crushing cone are quickly combined to make the material in the crushing chamber crush under the huge impact and crushing action of the crushing cone, and the crushing efficiency is high and the power consumption is low; The material is continuously crushed and falls freely under the action of self-weight and continuously discharged; the incoming material is subjected to multiple crushing actions, and each time it is broken, the orientation is re-arranged during the process of falling and being squeezed again. Therefore it is broken very fine and gets a good shape.
2) High yield. Compared with other models, the S series cone crusher has a long broken arm, large stroke and large crushing force. Large strokes and large crushing forces result in high yields. This is because: the material in the crushing chamber can be crushed more effectively; more material is crushed per stroke; the distance of the crushing cone from each stroke is larger than that of the rolling wall, allowing more material to enter the crushing chamber, A larger discharge volume is formed and the velocity of the material through the crushing chamber is increased.
3) Low daily operation and maintenance costs. The material selection and structure design are reasonable, the service life is long; the crushing force arm length reduces the load on the sliding bearing, gear and frame; the crushed product has uniform particle size and reduces the cyclic load; the overload protection device is reliable and reduces the overload; The clearing system is easy to operate and reduces downtime; the power consumption is allocated reasonably. The special design of the cavity of the s series cone crusher has many types of crushing chambers. The user can select the crushing cavity type with high crushing efficiency, uniform product size and good shape, uniform wear of the rolling wall and broken wall and long service life according to the site conditions. Dry oil seal dustproof: The dust seal structure is unique, the sealing effect is reliable, the lubricant replacement cycle and the service life of the parts are prolonged; special materials are selected to support the large crushing force.
The open circuit performance parameters of the S series standard cone crusher and short head cone crusher are listed in Tables 26 and 27, respectively. The external dimensions and base dimensions are shown in Figures 10 and 11, respectively.
1) The crushed product has finer particle size, realizes more crushing and less grinding, improves the production capacity of subsequent grinding operations, and reduces system power consumption.
2) Optimize the design parameters to make the output higher and the finer grain size, thus reducing the cyclic load. Less cycle load means less wear on the screen chute and belt conveyor, and lower power consumption of the conveyor.
3) The liner is easy to replace quickly, reducing downtime.
The open circuit production capacity and crushing chamber structure parameters of the H series cone crusher are shown in Tables 28 and 29, respectively, and the external dimensions are shown in Fig. 12.
Structural features of the inertia cone crusher: The structure of the inertia cone crusher is shown in Figure 13. The body is mounted on the vibration isolating device. The working mechanism of the crusher consists of a fixed cone and a rotatable crushing cone. The two cone working faces are respectively provided with a protective lining, and the opposite surface of the lining plate forms a crushing cavity. A bearing lining is arranged in the cylindrical hole of the vibration exciter, and the shaft of the crushing cone is mounted in the bearing lining, and there is a certain assembly gap between the two. The rotary motion of the motor is transmitted to the exciter through the V-belt drive system and the elastic coupling to rotate around the center line of the crusher. When the exciter rotates, centrifugal force is generated, and the centrifugal force forces the crushing cone to swing around the center of the spherical tile. If there is no material to be broken in the crushing chamber, the crushing cone rolls along the inner surface of the fixed cone without any gap. If there is material in the crushing chamber, it passes through the material layer, and the rolling is accompanied by the impact of the thickness of the material layer. Break the material. The broken product is discharged from the discharge opening, and the size of the discharge opening can be adjusted by adjusting the ring. In the working state, the resistance of the material along the crushing cavity is uneven, which will cause the change of the amplitude of the crushing cone. When the crushing cavity falls into the unbreakable object, the crushing cone will temporarily stop moving, but the unbalanced body exciter will Continue to rotate so there is no damage to the drive train.
The technical parameters of the inertia cone crusher are listed in Table 30. [next]
(1) The crushing chamber. The KCД and KMД-type crushing chambers (Fig. 21) can safely receive large pieces of material and crush them, but do not compact the material without overloading the crusher. In the calibration area, each piece of material must be squeezed to form a uniform particle size. The product has a large processing capacity. During the squeezing interval, the material can pass freely to improve the processing capacity; the computer program developed by the research equipment of the mining equipment technology company can match the shape of the crushing cavity and the inclination of the busbar, the eccentricity of the crushing cone and the oscillating frequency. Combined, the minimum power and liner consumption is guaranteed given the product size and throughput.
(3) Hydraulic unloading system. The hydraulic unloading of large unbroken objects guarantees the minimum downtime of the crusher in the event of an accident. When a large unbroken object falls into the crushing chamber and the crusher is stuck, the special hydraulic jack of the lifting support ring is used to quickly and safely unload the stuck crusher. The hydraulic unloading system (Figure 22) can also be used to unload crushers that are in a blocked state.
The hydraulic tool for tightening the cone lining and the adjusting ring journal lining are shown in Figure 24.

Cone crusher selection example (2)
Inertial cone crusher is a new type of ultra-fine crushing equipment with unique principle and structure. It relies on the inertial force generated by the high-speed rotation of the eccentric rotor to deflect the moving cone to break the material, and there is no rigid connection between the eccentric rotor and the moving cone, so it is broken with the eccentric cone. Compared with the machine, it has the following advantages.
(1) The material layer is selectively broken. Because the material layer between the two cones is subjected to strong pulsation impact, the self-crushing between the particles is caused, so that the wear rate of the equipment is low, and the power consumption per unit crushing is only 50% of the ordinary equipment.
(2) The crushing ratio is large and the product size is adjustable. The crushing force of the machine has nothing to do with the hardness and filling rate of the material, and the eccentric static torque and the rotational speed are adjusted. The crushing ratio is adjustable within the range of 4 to 30; if necessary, the over-grinding can be effectively prevented, and the yield of a certain fraction can be improved, or Increase the output of fine powder.
(3) Technical indicators are stable. The machine works at full load and the lining wear hardly affects the product size.
(4) Easy to operate and install. The machine is full of feed, no need for a special feeder, full load start and stop, operation, monitoring and control is very convenient.
(5) A wide range of applications. The inertia cone crusher can break brittle materials of any hardness. 1 various metal and non-metallic minerals. It can greatly reduce the particle size of human grinding, and achieve the most effective "multi-grinding and less grinding"; 2 refractory materials and abrasives. It can process refractory materials and abrasives with certain "toughness" and hardness; 3 metallurgical slag. It can fully dissociate the useful components and impurities, and create conditions for effective sorting and comprehensive utilization; 4 building materials. It can directly replace the rod mill to produce glass raw materials, effectively reduce over-grinding, improve resource utilization, and be used for crushing cement raw materials, which can increase mill output by more than 40%; 5 powder metallurgy. It has been broken for neodymium-iron-boron carbide material, metal manganese, molybdenum, cobalt alloy; â‘¥ foundry sand broken all the required finely divided materials.
9. Sandvik For more than 100 years, Sandvik has developed, produced and delivered a wide range of technologically advanced crushers that are used in a wide range of industries including mining, construction and mineral processing worldwide. These include stationary and mobile crushers for a wide range of materials, and the equipment range covers everything from high-capacity primary crushers to fine crushers for sand making.
The structure of the Sandvik hydraulic cone crusher produced by the company (see Figure 14) is derived from the single-cylinder hydraulic breaker and has maintained a leading position through continuous improvement and upgrading.
The hydraulically tuned Hydrocone cone crusher manufactured by Sandvik's crushing and screening division combines ruggedness and high performance with a CLP constant crushing cavity design and high-powered motors, making these crushers capable of other types of specifications. The bigger crusher rivals it. The Hydrocone cone crusher can be equipped with an ASRi discharge automatic control system to further enhance its performance. At the same time, ASRi also enables the crusher to be integrated into complex crushing plant automation systems.
The hydraulic cone crusher is an ideal crushing device for medium and fine crushing. The compact design and easy-to-maintain design make it the best choice for mobile crushing plants.
CLP means that the performance of the liner remains constant. The feed port area of ​​this crushing chamber (Fig. 15) remains almost vertical, and the shape and volume of the crushing chamber are almost constant throughout the wear of the liner. Therefore, the production capacity is also kept constant. The traditional non-CLP cavity type has a significant decrease in productivity with the wear of the liner.
Advantages of CLP constant crushing chamber: The allowable feeding size of the feeding port remains unchanged; the processing capacity is increased, more high-quality products are produced; the life of the lining plate is extended, and the running cost is greatly reduced.
Each type of hydraulic cone crusher has several standard crushing chamber types. By selecting different crushing chamber type and eccentricity, it can be easily adapted to the parameters such as feeding and crushing products, so the application range is very wide. When used in combination with a jaw crusher or a primary crusher, the hydraulic cone crusher can be used as a two-stage crusher. It can also be used as a three-stage or four-stage crusher to produce a variety of crushing that fully meets the requirements. Products, such as the CSC technology developed by the company (Cylinder Crushing Technology), can produce high-quality stone with excellent grain shape.
The hydraulic cone crusher uses a comprehensive automatic control technology. The Hydroset hydraulic adjustment system features overload protection and drain adjustment. It contains a heavy duty hydraulic cylinder to support the spindle and adjust the spindle position.
The Hydroset hydraulic adjustment system provides automatic overload protection for the crusher. It allows the spindle to be lowered with the moving cone liner so that the iron or other non-breakable material quickly passes through the crushing chamber.
The hydraulic cone crusher is equipped with the ASRi intelligent discharge automatic control system (Fig. 16), which can continuously monitor the actual crushing load inside the crusher, so that the crusher utilization can be optimized and the crusher can be used throughout the work. Can perform at its best. [next]
Among them, large crushers such as the H8800 have a certain production capacity, and they can all be incorporated into the automatic process control system of the crushing plant. When these crushers are delivered from the factory, the ASRi automatic discharge opening adjustment system is available as standard.
ASRi has strong data sharing capabilities and is easily connected to the user's control system and computer network. At the same time, ASRi also has a variety of display languages ​​including Chinese, which is convenient for users in various countries.
The hydraulic cone crusher is easy to operate and maintain. All maintenance and inspection can be done from the top of the crusher. This makes the operation of the crusher easier and the maintenance cost is lower. The improvement of the internal structure seal of the crusher provides effective protection against dust and other fine particles entering the internal parts of the machine, thereby reducing the maintenance workload and further improving the service life of the crusher.
The optional ASRi Drainage Automatic Control System not only optimizes the crushed product, but also tracks the wear of the liner. With the ASRi system, it is easy to develop a liner replacement plan that minimizes downtime.
(1) Product particle size curve. The product particle size curve and the percentage of broken product smaller than the tight side discharge opening (CSS) size (square hole sieve, mm) are related to the crushing work index (Wi) of the ore supply, the grain size characteristics of the ore, and other factors. The product particle size curves of the S-type and H-type hydraulic cone crushers are shown in Figures 17 and 18, respectively.
(2) Its characteristics are: 1 The structure of the body is simple and sturdy. The horizontal force of the moving cone is supported by the upper and lower ends of the main shaft at the same time. The force condition is good, and the broken shaft and the bushing are not easy to be damaged. 2 The constant crushing chamber (CLP) design makes the maximum feed size and the diameter during the wear period of the lining. The production capacity remains basically unchanged, and the total operating cost is low; 3 S type and H type are optional. The S type is used for the two-stage crushing of the large feed particle size, and the H type is used for the two-stage and three-stage crushing. Up to ten kinds of crushing cavity type changes, adapt to different product requirements; 4 the same eccentric bushing can be rotated 4 positions, thus obtaining 4 different eccentricities to adapt to different working conditions; 5 intelligent breaking The machine control system ASRi maximizes crusher performance and reduces operating costs. ASRi also features advanced operational data logging, liner wear display, better overload protection and easy drain measurement. ASRi has a multi-language display interface including Chinese. It also has strong network functions. Remote monitoring and data sharing can be realized through dedicated or general-purpose software such as WINI.
