Stone of crushing by the following factors usually:
1) the type of material
2) hardness, content of silicon, water content broken material of
3) Before in the crushing system , the material of particle size on average
4) granularity , and the proportion of each size range requirements, finished product use
MissionKitBasalt, fai green rock, granite, and other stones belong to high hardness, which silicon content is higher. in the actual operation it is rather diffcult to crushing, and have high cost of materials crushed.
Generally speaking, basalt and hui green rock is hard and fat material. granite is hard and brittle material. HeLuanShi has relatively low hardness a bit, but the highest content silicon.
In the actual operation of the broken, some customers use limestone, the board of jaw crusher wear down low .So a pair of board to the service life of a year is a very common phenomenon.
This is because the limestone is not only very low hardness (4 ~ 5 level), and stone of silicon content is very low, the crusher of wear parts of the abrasive is very low.
For crushing of basalt and granite, jaw plate, plate hammer, impact plate of the loss of wear parts is very high. Customers' production cost is more than the cost of production. Therefore,in the design of the process of broken,we dopt the selection of the pressure of the principle of crushing equipment as far as possible , in order to reduce the loss of wear parts. The typical laminated equipment configuration is two level jaw broken or jaw broken and cone broken technology configuration. If customers have higher demand for the final shape of the stone, we can configuration a impact crusher ,which can formed three sections of broken technology configuration. Three sections of broken will inevitably lead to the project investment cost more higher, but to long-term operation of the aggregated rock , three sections of lower production cost is very considerable.
On the above difficult material,it also can use jaw breaker and impact breaker . But this will inevitably lead to the counter of the plate hammer loss very high, plate hammer short life, return material higher proportion . which is worth manufacturer and customer problems needing attention.
Below are the three typical work process scheme:
Solution one: feeder machine,jaw crusher,imapct crusher,vibrating screen conveying system, control system.
Scheme two: the feeding machine mandibles crusher fine type jaw crusher, impact breaker (optional) vibrating screen conveying system control system.
Solution three: the feeding machine jaw crusher, cone crusher, impact breaker (optional) vibrating screen conveying system control system
In the three solutions, the second way is to choose to blow broken broken the impact breaker mainly, or with laminated broken primarily finely jaw crusher, cone crusher.
If the market for the finished products of stone type grain have requirement, the user wants to reduce the cost of tons of parts, we can consider the coarse jaw small jaw broken/cone broken as thick with two broken So it not only reduce the wear of the counter cost, also can get grain shape good stone.


As the professional manufacturer of complete sets of mining machinery, such as Secondary cone crusher,Sand washer supplier,Ball mills,Hydraulic cone crusher, Henan Hongxing is always doing the best in products and service.
