Now, cone crusher technology is applied in industrial production. It has made great social and economic benefits, but the use of vibration crushing technology is still not stopped, especially the use of vibration crushing technology. Due to the large crusher larger self-unbalanced force needs is the basis of the carrying capacity of the whole suspension of this program on the basis of the crusher higher, reliability, security, poor but inertia cone crusher products than conventional crusher the superior alternative crushing and coarse grinding two paragraphs job.

By improving access to the second generation of inertia cone crusher spring supports the entire crusher, use of spring-loaded machine height decreased, improve security, but for this structure using the articulated sleeves and intermediate shaft, hinged using spherical ends with the difficulties in processing and manufacturing, lubrication is not convenient, and at the same time this uranium under exciter, exciter fulcrum under alternating load, reduce the service life of the components skewed because of the uranium in the role of the eccentric weight at the same time, so that the moving cone boundary effects, often crushing ratio decreased.

Inertial jaw crusher and other crushers further development is the use of the hydraulic system regulating uninstall gap, the method is to move along the vertical direction and supported on the hydraulic cylinder piston inner cone. And the development of a dedicated cross-sectional shape of the crushing chamber, the best cross-sectional shape of the crushing chamber can significantly increase the degree of the largest block of the material to be broken, and new inertia cone crusher, its block by 20mm increased to 60mm. Crushing block in this growing state and inertia cone crusher production capacity actually has not changed. Above program founded more large inertia cone crusher can replace two devices for crushing and grinding.

The crushing process there will be a big step forward, vibrating cone crusher can produce a lot of fine ingredients, used in mining production, most of the production has reached the size requirements, to simplify the process, and classifying device composed of closed-circuit. Completely cancel the follow-up of the grinding process, such as the and hydro cyclone combination, form the final mill system, eliminating the need for a process under the ball mill; combined inertia cone crushers and classifiers used in powder metallurgy, ceramics, refractory materials and other industries joint operations, without the ball mill and then.

Impact crusher, commonly known as the sand making machine, is one kind impact which has the international advanced level of energy consumption. It’s the most effective, practical and reliable gravel machine and impact crusher is mainly used in four areas:
(1) Artificial sand making.
(2) Production of aggregate and high-purity materials.
(3) For the pre-production stage of mining crushing process, widely used in the chemical, mineral, cement and building materials industries where materials are broken;
(4) For high corrosive substances and other materials secondary crushing disintegration metallurgy, metallurgical industry and construction waste crushing etc.

The following are several applications in the industrial production of impact crusher all-rounder:

Sand making

When the industry is not yet developed, river gravel resource has been shelved, and later with the development of architectural changes and materials, river pebbles gradually became a momentous source of building materials. Now these river gravels have entered into our line of sight, the truck carries large stones go to the factory with the impact crusher for crushing. River gravels become the main building materials through further grinding and processing. During the process of sand production, impact crusher contributes to its incomparable abilities to crush materials.

Here we will list some professional tips for using and maintaining the portable jaw crusher and the way of ruling out the trouble.


Jaw crusher as primary crushing equipment in the process of crushing, generally deals with the first time crushing for large materials because of its simple working principles, product durability, simple maintenance and crushing higher compressive strength. So it has been widely used in the field of broken.

Before starting the jaw crusher, we should best drive wheel to turn first one to two laps to confirm the rotation part well. In the work process of the jaw crusher we should pay attention to the temperature of the bearing parts. We should also make the bearing parts keep good lubrication and pay attention to the noise and vibration at work without abnormal situation. When there is abnormal sound or vibration, we should stop it and check whether jaw crusher parts are damaged.

Jaw crusher is a kind of coarse crushing equipment. In using the portable jaw crusher process we cannot full the crusher of ores in a time. The method of directly unloading ores into the mouth of jaw crusher is not feasible. It may affect the normal work of the jaw crusher and exert its efficiency. Jaw crusher and other crushing equipment should feed the ores by professional feeders. Before feeding the ores into jaw crusher we should rule out the iron to avoid damage to the crusher. In addition, because the jaw crusher must be started when the bin is clean, at the end of each use the jaw crusher should be emptied the ores before it is closed. In the using process we should also pay attention to the angle between fixed jaw of jaw crusher body and static jaw body which should has a proper scope. Usually the production efficiency is inversely proportional to the size of the mouth. So we need to adjust the angle according to the actual size.

In the work process of the jaw crusher we should keep feeding uniform and prevent instantaneous overload. We should also prevent the broken objects with materials such as metal and wood from going into the machine. Regularly check the jaw crusher whether the discharging granularity is in line with the requirements. If there is too much excess of the prescribed size of particles, we should find out why the gap is too large (such as bar, discharging mouth too wide, the hammer wear, etc.), and take the appropriate improvement measures. Power supply safety device should be kept in good condition. It is strictly prohibited to use unqualified materials in order to save trouble or money.

Before the end of the operation of jaw crushers, we should stop feeding and wait for the emptying of materials in the first row of net. We can cut off the jaw crusher power input.

Maintenance for jaw crusher: keep every month two minor repair, once a yearlong and once every three years the overhaul maintenance frequency. The major part of the jaw crusher should be paid special attention to being regularly checked, especially the dynamic and static jaw body due to its direct contact with the ore. We should keep replacing it periodically and regular maintenance. In addition, the temperature of the bearing and the use of bearing grease should also be noticed during jaw broken hardware maintenance. We must pay attention to that the bearing temperature cannot be higher than 70 ℃. If the bearing temperature is too high, we should check the lack of grease. After a period of use, we should also fix the anchor bolts. During the maintenance of jaw crusher, we should check whether the fastening bolts are strong and the wearing degree of the parts which is easy to wear. And we should give timely replacement or repair once we find the problems.
