The appearance of jaw crusher was in 1858, which was widely used in road paving, mining. Jaw crusher owns the advantages such as bigger crushing ratio, simple structure, credible operation, easy to be maintained, average granularity, lower operation cost, and this machine is being used to crush those materials whose compression strength is no more than 350Mpa.
The demand for mineral resources is being increased all the time because of the social and economic development in the modern society, but our national mineral resources cannot satisfy the overall marketing demand because the economist analysis that there will be one new tide for mineral resources, so the demand of the whole mining market will still be strong and enormous.
The excessive exploration of mineral resources in the past certainly would lead to the pollution and resources wasted, and the main reasons of causing one situation are owing to the poor technology. That is the reason why our country enhances the creation and development ability in order to avoid some problems happened.
The main function of those large-sized jaw crusher in the mineral resources' exploration is being used for the primary crushing, so it becomes one of the most popular machines in the whole mining field because all of those processed mineral ores are required to be crushed by jaw crusher for the primary crushing process. The quality of the whole mineral ores can directly be determined by the performance characteristics of jaw crusher.
