Understand The Structure And Principle Of Jaw Crusher

In the data released by the Department of transportation, the construction cost of Expressway alone has reached more than 700 billion yuan. There are 31 expressway projects under construction in China. With such a huge number, the demand for raw materials in the infrastructure industry is growing, and the production demand for jaw crushers is also expanding. In the process of construction, subgrade is often an important part of the highway. Jawbone has played a great role in the construction of 7 projects of 203 km in many highway sections. Therefore, it is necessary to understand the jaw crusher structure diagram, jaw crusher structure principle and jaw crusher mechanism.

It is necessary to understand the structure diagram of jaw crusher, the structure principle of jaw crusher and the construction of jaw crusher. First of all, we all know that the subgrade of expressway has two basic forms according to the different terrain conditions: embankment and cutting, commonly known as filling and excavation. The materials for subgrade construction, whether filling or excavation, are mainly earth rock bulk materials. Guangdong is rich in stone resources. At present, many expressways use stone roadbed. However, in order to ensure the stability and comfort of the train in high-speed driving, the subgrade should have enough firmness, stability, durability and reasonable rigidity. How to achieve this effect? Crushing is the key! If large stones are directly used for paving, it will inevitably bring hidden dangers to the safety and stability of the road. Our expressway project team is an expert with rich construction experience. They decided to use the structural principle of jaw crusher to carry out the preliminary processing of stone before the commencement of construction. Therefore, the stone particle size is very uniform, with less dust and no debris, which is very in line with the standard of sand and stone for subgrade construction.

In the process of high-speed construction, especially in Shenzhen section of Guangzhou Shenzhen Expressway, due to the rich resources of pebbles in the local area, the crushed stones of pebbles are mostly used as subgrade. However, the hardness of the pebble is very large, which leads to the rapid wear of the equipment, and the replacement of moving jaw plate and other parts is very frequent, even the whole equipment can not be spared. After looking up and comparing the structural drawings of various jaw crushers, the project team decided to invite the jaw crusher manufacturers to participate in the design and improvement of the equipment. After analyzing the local stone and the existing jaw crusher structure principle, the engineer improved the jaw crusher structure, and introduced the jaw crusher suitable for the continuous production of hard stone, which is more efficient, energy-saving, more convenient and reliable.
