After international financial crisis, the railway construction investment was put on an unprecedented level as an important means of stimulating domestic demand. Railway construction has entered into a summit; a large number of the stone production lines are put into operation. Therefore, a large number of quarry crusher machine is highly demanded.
First, quarry stone from the stone field is separated from the quarry face by blasting. Then, quarry stone is transported to the rock field. Through a series of crushing machine, screening equipment, the stone is crushed, screened into different size windrow. In this process, we must ensure that productivity meet the requirements, and reduce needle flaky particles while producing cube-shaped aggregates that meet specified size. For saving energy, reducing workman and machine maintenance, and expand equipment life span, it is better to reduce the maximum size of input material, to reduce congestion and blocking when feeding, and to exclude hard broken materials.
Large stone through the hopper are evenly sent by the vibrating feeder to jaw crusher for broken. After the first broken, the stone through the belt conveyor are sent to impact crusher for further broken. Then different types of stone are screened out by vibrating screen. Stones that meet the size requirements are sent to the finished windrow through conveyor belt, while those that do not meet requirements are sent back to impact crusher to crush again. Finished size can be adjusted and graded in accordance with the needs of users. Being equipped with auxiliary dust deducing equipment, the crushing plant is more environmental-friendly.
In the quarry production process, the stone crusher machine is very important. It is related to the final product. Now we will introduce the stone crushing in details.
