Cone crusher

Cone Crusher A crushing machine suitable for use in raw materials in the metallurgical, construction, road construction, chemical and silicate industries. According to the different crushing principle and different product particle size, it is divided into many models. The crusher is widely used in many sectors such as mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The cone crusher has large crushing ratio, high efficiency, low energy consumption and uniform product size. It is suitable for medium and fine crushed ores and rocks. The models are mainly divided into SMG series, spring type and HPC series, and their working principle and structure are introduced respectively. It also introduces in detail the development history, working principle, composition, influencing factors, technical advantages, operational matters, common faults and inspection and maintenance of the cone crusher.

Cone crusher history

In 1927, a cone-shaped cone crusher (hereinafter referred to as a slow cone cone crusher) was officially used in industry. This type of cone crusher has a Simon standard and a short cone crusher and a spherical cone crusher.

Soon, the steeply inclined compression cone crusher was also introduced. The crusher was called a compression rotary crusher. In essence, the crusher was improved on the basis of the gyratory crusher and used between medium and fine crush. The crusher has the same shape and structure as the short-shaft gyratory crusher. It has a steep taper surface, a small discharge port, a short spindle, a large stroke and a high speed.

By the end of the 1950s, the cone crushers manufactured in various countries began to use hydraulic technology extensively, which further improved the cone crusher. At this time, the slow cone crusher used hydraulic pressure or the original spring overload protection device and the tapered surface. Air pressure regulating discharge port device, hydraulic overload protection device and hydraulic locking device.

At the same time, the steep cone cone crusher also adopts hydraulic technology while retaining the original steep moving cone surface. According to the location of its hydraulic setting, it can be divided into bottom hydraulic support or top hydraulic suspension. Cone crusher. Since the regulation of the discharge port and the overload protection device adopt a unified hydraulic system, the structure is simple.

In the 1970s, the cone crusher made progress in two aspects. One was the large cone crusher of 3050 mm, and the second was a steep cone and a cone cone cone crusher capable of producing extra fine materials. The latter has a new type of crushing cavity structure, the spindle is short, and the material of 4 mesh can be obtained.

The cone crusher consists of the above two main types, but other types, such as the multi-cylinder hydraulic crusher without gear rotation, the multi-cylinder crusher is actually only used for the locking device, and can not be combined with the bottom single-cylinder hydraulic crusher. The top single cylinder hydraulic crusher is comparable.

Multi-cylinder hydraulic cone crusher

Structural principle of hydraulic cone crusher

When the multi-cylinder hydraulic cone crusher is working, the motor drives the eccentric sleeve to rotate through the V-belt, the transmission shaft and the bevel gear pair, and the moving cone performs the swing motion under the action of the eccentric sleeve, so that the moving cone and the fixed cone are sometimes deviated from each other. The material is continuously crushed and impacted in the crushing chamber and broken, and the material is broken to the required particle size, and the drop is discharged from the bottom.

The special crushing chamber designed by the principle of intergranular lamination and the matching speed are used to achieve selective crushing of the material, so that the material to be crushed has a higher degree of fineness and better granularity. Multi-cylinder hydraulic cone crushing capacity has higher output than similar models, and there are many crusher types for each specification. Users can choose different cavity types according to different process requirements.

Product advantages of hydraulic cone crusher

Structural upgrades are more efficient

Based on the unique spindle fixed and eccentric sleeve rotating structure, the equipment further optimizes the design of the rotating parts of the transmission and the lubrication and sealing structure. The equipment has strong bearing capacity, and the installed power reaches the same machine type, which is very large, small in size and high in efficiency. low.

Laminated broken, good grain shape

The material is crushed by the principle of laminating and crushing. By optimizing the equipment and cavity type, the laminating crushing efficiency is improved, the crushing efficiency is high, the wear of the wearing parts is low, the finished grain shape is cubic, the fine grain content is high, and the finished product quality is improved. Reduce the production costs of equipment and the entire system.

Full hydraulic control, accurate and reliable

The use of full hydraulic control, the equipment from the insurance clearing chamber to adjustment and locking, all hydraulic operation, work more stable and reliable, easy to operate. Combined with rich practical experience, the hydraulic system structure is fully optimized, the adjustment control is more accurate, the automatic protection reaction speed is faster, and the fully automated operation can be realized.

Multi-cavity conversion

It is equipped with a variety of medium and fine crushing chambers. It only needs to replace a small number of parts such as corresponding cavity liners, which can be converted between cavity types, combined with the principle of laminating and crushing, to better meet the requirements of medium and fine crushing process. A multi-purpose machine.

Hydraulic lubrication integration equipment control automation

Equipped with an integrated hydraulic lubrication system and a centralized intelligent intelligent control system, it saves the cost of hydraulic lubrication and monitors the operating status of the equipment in real time. The control system is further optimized, the system is more stable and reliable, and the safe and stable operation of the equipment is ensured, and the operation of the device is more worry-free and labor-saving.

Single cylinder hydraulic cone crusher

Working principle

cone crusher

When the HST series single-cylinder hydraulic cone crusher is working, the motor drives the transmission shaft of the equipment through the pulley and the V-belt. The transmission shaft drives the eccentric sleeve to rotate through the large and small bevel gears. The moving cone makes the swing motion through the eccentric sleeve through the main shaft. The cone and the fixed cone are sometimes close to each other, and sometimes away from the rolling wall, and the material is continuously crushed and impacted in the crushing chamber between the rolling wall and the crusher, and the broken material is discharged from the lower portion.

High efficiency spring cone crusher

High-efficiency spring cone crusher is based on the introduction and absorption of foreign technology, based on the customer's needs, based on the principle of laminating crushing and multi-breaking and grinding concept design, the high swing frequency, optimized cavity and reasonable stroke are integrated. Modern high performance crusher.
