In 1907, Germany developed a mobile crushing unit, which walked by itself on rollers and was equipped with a screening device.
       In 1956, German krupp company developed mobile crushing station, which was the first large-scale mobile crushing station in the world and was applied to quarries, which had a great influence on the development of mobile crushing station in the future.
       With the rapid development of industry in our country and constant progress, for a variety of resources, such as phosphate rock, non-ferrous metals, coal demand increasing, many from the ground or near the ground mining developed into deep mining, the current adopt the broken pieces of stationary or mobile station has been unable to play the advantages of its own, so develop the mobile crushing plant has become an important development direction in the future, and the situation became more and more urgent.
       Chongqing longjian group has been focusing on mining machinery and equipment for nearly 30 years and is committed to making a contribution to China's manufacturing industry.
Through continuous research and innovation, the successful launch of cross trowel mobile crushing station brand.
       Small make up, here is a brief analysis of the development of mobile crushing station in the future,        the shortcomings hope to be understanding.

       Mobile crushing station is a large equipment that integrates feeding, crushing and conveying. At present, it can be used in material conveying and processing places, such as metallurgy, mining, chemical industry, building materials, hydropower and other industries.
Mobile crushing station has gradually become the main equipment for continuous operation and semi-continuous process intermittent operation. It has been widely used in iron ore, phosphate ore, non-ferrous metal, limestone and other hard rock stopes.

1. Structure characteristics of mobile crushing station

Generally speaking, mobile crushing station is mainly composed of receiving hopper, feeder, crusher, discharging arm, steel structure, crawler walking device and other parts.
According to the difference between its position and shifting mode, it can be divided into two types at present: self-shifting mode and other shifting mode. From the perspective of market application, the former one is widely used and has a trend of increasing gradually.

When the self-moving crushing station is in operation, the material is directly fed by the excavator or bucket, which has many functions such as feeding, crushing and conveying. It can eliminate the intermediate link of automobile transportation and improve the loading speed and efficiency. At the same time, the semi-continuous process system of the self-moving crushing station has low production cost and flexible walking movement.
Its walking device has the tire walking type, the hydraulic step type, the crawler type and the track walking type and so on.

He moves the crushing station.
Generally, the movement is completed by crawler transporter or other towing (towing) equipment. According to the weight and height of the whole equipment, the moving and setting mode can be divided into integral moving and setting or split moving and setting.

Second, the advantages of mobile crushing station

1. Mobile crushing station has the characteristics of flexibility, convenience and strong mobility, which can greatly save the cost of infrastructure investment or equipment relocation in mining, transportation or processing.

2. The installation of a whole set of integrated unit equipment avoids the installation of infrastructure such as split components on complex sites and reduces the consumption of human, material and financial resources.

3. Mobile crushing station can not only process materials on site, but also move along with the continuous advance of the mining face. It is not necessary to move materials away from the site through automobiles or conveyors before crushing and processing materials, which can greatly save the transportation cost and time of materials.

4. Flexible combination and strong adaptability.
According to different crushing process requirements to form a different process, but also can be run separately.

5. Reliable performance and convenient maintenance.
At present, the main equipment components of mobile crushing station have been optimized and strengthened, showing the characteristics of high strength, excellent performance, compact structure and convenient maintenance.

Third, the domestic mobile crushing station development

Compared with the advanced countries in the world, China is accelerating the development of mobile crushing stations and has made continuous progress.
In 1968, in the process of learning from and absorbing the experience and technology of foreign mobile crusher, China independently developed the first mobile crushing station, whose crushing capacity reached a medium level, high production efficiency, energy saving, flexible movement and easy installation laid a foundation for the development of China's mobile crushing station.

At present, domestic mobile crushing station manufacturers constantly adjust the direction and focus of the industry, on the basis of constantly learning from and absorbing foreign advanced technology, increase the support of scientific research funds, and vigorously improve the level of independent research and development and manufacturing of mobile crushing station.
Chongqing longjian group is fully aware of the development trend of mobile crushing station, overcomes all kinds of difficulties, increases the development strength, and successfully launches the klaas trowel KLSM mobile crushing station, striving to make a contribution to the rejuvenation of the national equipment industry.

Iv. Development and improvement direction of mobile crushing station

Cross trowel mobile crushing station under chongqing longjian group will continue to innovate and develop from the following aspects:

1. Large scale and oversize.
Large scale can improve the processing efficiency of equipment, reduce the investment in infrastructure and save the cost. Therefore, it is necessary to strengthen the research and development in the future, and the development of large mobile crushing stations will become the development trend of mobile crushing stations in the future.

2. Improve the level of automation.
Through the use of advanced equipment or technology, make the whole crushing system more perfect, the whole crushing process to achieve a high degree of automation control.

3. Improve the reliability of the equipment.
As mobile crushing stations are heavy in weight and generally work in very harsh environments, they require high reliability. Therefore, on the premise of meeting the production needs of mobile crushing stations, the structure of mobile crushing stations should be simplified as much as possible to reduce production costs and improve reliability.

4. Improve the maintainability of the equipment.
Because the mobile crushing station is generally uninterrupted work, once shut down will cause a great loss, so the requirements for its maintainability is higher.

5. Noise prevention and control.
The existing mobile crushing station has a large noise, which is harmful to the physical and mental health of the workers, so it is necessary to strengthen the research on the prevention and control of the noise in the future.

6. Dustproof.
Mobile crushing stations generally work in very bad conditions, with serious dust and air pollution, which is not conducive to the physical and mental health of workers. Therefore, it is necessary to strengthen the research on dust prevention and pay more attention to environmental and social benefits.

The development prospect of mobile crushing station

At present, as the world resources consumption increasing, the large increase in mine production, the mining depth increasing, the advantages of mobile crushing plant more highlights, and mobile crushing plant technology matures, more diverse products, in the mining industry to promote large complete mobile crushing station, to reduce the mining cost, promote the rapid development of the mine is of great significance in the world.
