1. The development of mobile stations
With the gradual expansion and increase in the number of open-pit mining in my country in recent years, the use of semi-continuous mining technology is the fundamental way to reduce mining costs and save fuel consumption, and is the development trend of open-pit mining projects. The emergence of the mobile crushing station has created conditions for the realization of the advanced semi-continuous process of mining with a single bucket electric saw, a mobile crushing station, a belt conveyor, and a dumper, which has been gradually applied and promoted in China. The semi-continuous process is a new type of open pit mining process developed in the 1960s and first applied to a limestone mining company in Germany. After years of application and development, the technology has become increasingly mature.

The mobile crushing station is one of the important core equipment for open-pit mining. Its innovation lies in its unique functionality and mobility. It assembles traditional crushing and screening equipment together, and realizes automatic or Semi-automatic control enables it to move freely with the electric shovel on the mining face, and transport the crushed materials through the belt conveyor system, thus completely getting rid of the use of trucks, greatly reducing the operating cost of open-pit coal mines, and bringing significant impact to the mine Economic benefits. This equipment has been used in many large open-pit mines in Inner Mongolia and Shanxi. With the development of large open-pit mines throughout my country, mobile crushing stations will be more and more used. Therefore, the development and localization of this equipment has become an important issue in open-pit mining. Now let's talk about the mobile crushing plant based on the domestic situation.

2. Composition of mobile crushing station
The mobile crushing station is a crushing and screening unit composed of several crushing and screening units that are combined and installed on a movable frame according to the process requirements. According to the material crushing process, several crushing and screening units are selected to form a crushing production line. Usually, the materials are uniformly transported to the crushing equipment through the feeding silo and feeder, and the crushed materials are transported to other crushing and screening units by belt conveyors. The materials are crushed and screened into the required particle size, and then transported to the finished product pile by the belt conveyor. The mobile crushing station is a mobile crushing and screening equipment that integrates feeding, crushing, screening, conveying and electrical control.

The core equipment of a mobile crushing station should be a crusher. There are several types of crushers currently in use in mobile crushing stations: jaw crusher, gyratory crusher, cone crusher, impact crusher, hammer crusher, roller crusher, toothed roller crusher , Vertical shaft impact crusher, etc.

3. Mobile crushing station has the following advantages:
1. Flexible mobility:

It is very convenient for ordinary mobile transition and saves the time of quickly entering the construction site. It is more conducive to stationing in a reasonable construction area, eliminating the cumbersome steel frame structure and foundation construction during the crushing process, saving a lot of time.

2. Reduce material costs:

The station can be directly selected and opened to the station to directly reach the finished product size; in addition, the expansion unit can directly send the crushed material to the specific conveyor belt conveyor, thus eliminating the transportation cost. Customers can provide more flexible process planning configuration according to the material types and product requirements in the process, and meet the various requirements of users such as mobile crushing and mobile screening, so that the organization and logistics transfer are more direct and effective, and the cost is low. maximize. .

3. Strong adaptability and flexible configuration:

The mobile crushing station provides customers with a simple and low-cost special combination unit configuration. For the medium crushing and screening system, it can be operated independently by a single unit, or can be flexibly composed of system configuration units.

4. Reliable performance and reliable maintenance:

Mobile crushing stations are generally equipped with high-performance crushers, which have high crushing efficiency, strong versatility, excellent quality of crushed products, lightweight and reasonable structure design and excellent crushing performance. The largest range meets the requirements for crushing and screening of coarse, medium and fine materials.

The mobile crushing station developed and produced by Zhejiang Lizhi Machinery Co., Ltd. has the characteristics of high processing capacity, large feed inlet, small transportation volume and low wear cost. It can directly penetrate the construction site of the builder. Small stone processing plant, intelligent and efficient.
