What is jaw crusher used for?

Friday June 9, 2023 Comments 0

The jaw crusher can be used for the processing of granite, marble, basalt, limestone, quartz stone, river pebble, iron ore, copper ore, and other materials. Generally used for primary crushing, it is the first-choice equipment for various crushing production lines.


Jaw crushers are mainly used as coarse crushers and medium crushers in mining, building materials, infrastructure, and other sectors. According to the width of the feed port, it is divided into three types: large, medium, and small. The width of the feed port is greater than 600MM for large machines, the width of the feed port is 300-600MM for medium-sized machines, and the width of the feed port is less than 300MM for small machines. machine. The working part of the jaw crusher is two jaws.


One is a fixed jaw (fixed jaw), which is vertically (or slightly inclined at the upper end) fixed on the front wall of the machine body, and the other is a movable jaw (moving jaw). Inclined to form a crushing cavity (working cavity) with a large upper and a lower jaw with a fixed jaw. The movable jaw plate makes periodic reciprocating motions against the fixed jaw plate, sometimes separating and sometimes approaching. When separated, the material enters the crushing cavity, and the finished product is discharged from the lower part; when it is close, the material installed between the two jaws is crushed by squeezing, bending, and splitting.


The mining industry. Since the raw ore materials are relatively large, a certain amount of crushing is required during mining, which is convenient for transportation. The jaw crusher has a large crushing ratio and uniform product size. The discharge opening has a wide adjustment range, which can meet the requirements of different users and other excellent performances. It is an ideal crushing equipment for the exploitation of various mine resources.

Construction industry. For the construction industry, all kinds of concrete used also need to be crushed to achieve the required particle size before it can be used in construction production; for example, the application of raw material crushing in cement production, the application in concrete production, and even construction The application of garbage recycling links, etc., in short, the development of the construction industry is indispensable for the help of jaw crushers.

Road construction. The road construction industry is the same as the construction industry. The materials needed for road construction must be crushed. The higher efficiency of the jaw crusher is exactly what is needed in road construction.

Water conservancy industry. In recent years, the demand for sand and gravel aggregates for water conservancy projects is very large. The early supporting projects including the construction of production and living infrastructure and the construction of construction roads, as well as the main construction of the hub project in the later stage, require a large supply of sand and gravel aggregates. The supply and production of these large amounts of sand and gravel aggregates are also inseparable from the participation of jaw crushers.

A jaw crusher is an earlier crushing equipment. Because of its simple structure, sturdiness, reliable work, easy maintenance and repair, and relatively low production and construction costs, it is still widely used in metallurgy, the chemical industry, building materials, electric power, For transportation, and other industrial sectors, it is used for coarse, medium and fine crushing of various ores and rocks with a compressive strength between 147 and 245MPa.


Jaw crushers are mainly used for medium-size crushing of various ores and bulk materials, and are widely used in mining, smelting, building materials, highways, railways, water conservancy, and chemical industries. The maximum compressive strength of the crushed material is 320MPa.
