In recent years , the development of highways, railways, housing construction , and its construction materials that end icing on the cake . Over the years, the stone is one of the indispensable materials of construction projects , whether it is water or road construction projects are inseparable from the sand and gravel aggregate.
As we all know , there are generally sand and gravel ore production, such as granite , basalt , limestone, river gravel, pebbles, calcite , where granite , basalt is the major highway and railway projects most commonly used materials.
Basalts are extrusive rock , volcanic eruption more relevant in the magma flow process, cooled and solidified to form , the main feature is a blowhole , rhyolite , etc., hard and tough . Granite intrusive rocks belong , because there is no spray the surface, close to the surface in the ground, the movement is slow, slow decline in temperature , so crystalline clear , hard and brittle. But they have in common is that both granite and basalt are high hardness and high silicon content , are more difficult to broken or crushed material in high -cost real crushing operations.
About basalt, granite crushing and processing of materials , generally choose jaw crusher and impact crusher two-stage crushing, but with the country in recent years to improve the requirements for the type of stone tablets , the choice of three stage crushing as possible , which is then plus a hydraulic cone crusher, reduce flakiness . Judging from the surface of a device be more enhanced the production costs, but the long-term operation of the quarry , the broken by crushing to a high hardness and high silicon content of the three sections of stone reduced production cost is very considerable.
The following is a typical granite , basalt crushing processing program :
1 vibrating feeder + jaw crusher + impact crusher + vibrating screen + Conveyor
2 vibrating feeder + jaw crusher crushing jaw crusher + vibrating screen + Conveyor
3 vibrating feeder + jaw crusher + crushing jaw crusher + impact crusher + vibrating screen + Conveyor
4 vibrating feeder + jaw crusher + impact crusher + hydraulic cone crusher + vibrating screen + Conveyor
Several more programs , if you do not ask for the material shape , you can use jaw crusher , fine jaw broken or broken jaw crusher + build production lines, but this program is to produce the stone buildings of the important buildings or high-grade unacceptable. For this production out of stone to fit a wider range of areas that need with hydraulic cone crusher, its biggest feature is the use of inter-particle crushing effect , reduce flakiness , more uniform grain size , can be used in roads, railways , airports , docks, building higher and so on.
